Development prospect of China's water treatment industry in 2019: increasing investment and promoting market scale growth

In recent years, the state has taken the improvement of sewage treatment and recycling utilization rate as an important and hard index for the implementation of "energy conservation and emission reduction", not only speeding up the urban sewage treatment and recycling, but also accelerating the construction of a harmonious socialist society, a resource-saving and environment-friendly society, and a socialist ecological civilization The pace of the construction of the facilities for biological utilization has also improved the concept and technical route of sewage treatment, making the transformation of sewage treatment from the promotion of standard discharge to the promotion of "low discharge" and sewage recycling. China's water pollution control has entered a new era of comprehensive promotion and moving to a higher stage, but compared with developed countries, the current level of treatment is still low, the speed of sewage treatment still lags behind the speed of pollution, and the task of development is a long way to go.  

Water treatment refers to the process of water quality conditioning, such as sedimentation, filtration, coagulation, flocculation, corrosion inhibition and scale inhibition, which is carried out to remove some harmful substances in the water that are not necessary for production and life through a series of water treatment equipment by means of physical, chemical, biological and other means, and to apply to specific purposes. As the social production and life are closely related to water, the water treatment field involves a wide range of applications, forming a huge industrial application. According to the statistical data of prospective industry research institute up to the end of the 12th Five Year Plan period, the investment in wastewater treatment during the 12th Five Year Plan period in China has reached 450 billion yuan; according to the wastewater treatment industry plan of the 13th Five Year Plan period in China, the investment in wastewater treatment during the 13th Five Year Plan period will reach 1392.2 billion yuan, more than three times of that during the 12th Five Year Plan period.

Industry status and development trend

1. Industry status

Basic situation of domestic water pollution treatment industry

Water is the basic element of life world and ecological environment, which can not be replaced by any other substance. In the 21st century, in the face of global water shortage and serious water pollution problems, the World Summit on sustainable development ranked water resources first in the "priority areas of sustainable development". Sewage treatment industry is undoubtedly a very important industry in the national economy. Domestic water pollution treatment demand is strong, the market space is broad.  

According to the statistics of the United Nations Environment Programme, water resources per capita less than 3000 ㎡ belong to mild water shortage, less than 1000 ㎡ belong to moderate water shortage, and less than 500 ㎡ belong to extreme water shortage. According to China Statistical Yearbook 2018 issued by the National Bureau of statistics, the per capita water consumption in 2017 was only 435.91 cubic meters, which is a country with serious water shortage. At present, China is in the period of economic development. With the continuous, long-term and rapid development of urban-rural integration and industrialization, the urban population is expanding rapidly, and the demand for water is rising. According to the data of the National Bureau of statistics, from 2014 to 2017, the total amount of wastewater discharge in China was 71.618 billion tons, 73.532 billion tons, 71.109 billion tons and 69.967 billion tons, respectively.  

During the 12th Five Year Plan period, the planned investment in the construction of urban sewage treatment and recycling facilities in China is nearly 430 billion yuan. Among them, RMB 244.3 billion will be invested in the improvement and construction of pipe network, RMB 104.0 billion will be invested in the new urban sewage treatment capacity, RMB 13.7 billion will be invested in the upgrading and reconstruction of urban sewage treatment plants, RMB 34.7 billion will be invested in the construction of sludge treatment facilities, and RMB 30.4 billion will be invested in the construction of renewable water conservancy facilities. The future market capacity of sewage treatment is large. According to the statistical bulletin of urban and rural construction in 2016 issued by the Ministry of housing and urban rural development, at the end of 2016, there were 2039 sewage treatment plants in cities nationwide, an increase of 95 over the previous year, with a daily treatment capacity of 149100 cubic meters, an increase of 6.2% over the previous year, and a drainage pipeline length of 577000 kilometers, an increase of 6.9% over the previous year. The total amount of urban sewage treatment is 44.88 billion cubic meters, and the urban sewage treatment rate is 93.44%, an increase of 1.54 percentage points over the previous year, of which the centralized treatment rate of sewage treatment plant is 89.80%, an increase of 1.83 percentage points over the previous year. The daily production capacity of urban reclaimed water is 27.62 million cubic meters, and the consumption of reclaimed water is 4.53 billion cubic meters.  

China's investment in environmental pollution control has increased from 110.670 billion yuan in 2001 to 95.3895 billion yuan in 2017. In 2017, the expenditure has increased by 8.62 times, with an average compound growth rate of 14.41%. According to this growth rate, by 2020, China's investment in environmental pollution control will reach 1.42 trillion yuan.  

 

At present, there are about 35000 enterprises engaged in environmental protection industry in China, with nearly 3 million employees and total industrial income of nearly RMB 1 billion. With the further increase of environmental protection investment, China's environmental protection industry will usher in a broader development space. According to the requirements of the 12th Five year development plan for environmental protection equipment, during the 12th Five Year Plan period, the total output value of environmental protection equipment industry will increase by 20% annually, and reach 500 billion yuan in 2015. The rapid development of environmental protection industry will also drive the rapid development of water treatment industry.  

In order to implement the national strategic emerging industry development plan of the 12th Five Year Plan and the energy conservation and environmental protection industry development plan of the 12th Five Year Plan, the Ministry of industry and information technology proposed in the implementation plan of major environmental protection technology equipment and product industrialization project issued in September 2014 that the annual average growth rate of environmental protection equipment manufacturing industry should be kept above 20% by 2016 With a total industrial output value of 700 billion yuan, major environmental protection equipment can basically meet the domestic market demand. According to the 13th five year plan for the development of energy conservation and environmental protection industry jointly issued by the national development and Reform Commission, the Ministry of industry and information technology, the Ministry of environmental protection and the Ministry of science and technology, by 2020, the added value of energy conservation and environmental protection industry will account for about 3% of GDP, the technological level will be improved significantly, the degree of localization will be improved, and the sales volume of major energy conservation and environmental protection products and equipment will double in 2015.  

(2) basic situation of domestic industrial sewage treatment industry

In terms of water environment pollution, it can be roughly divided into point pollution source, non-point pollution source and internal pollution source, and industrial sewage is an important pollution point source. According to the requirements of "ten water rules" in 2015, the prevention and control of industrial pollution sources is considered as one of the overall tasks of water pollution prevention and control. At the same time, by restricting industrial enterprises, it forces them to carry out environmental protection and upgrading.  

According to the relevant data of the National Bureau of statistics, the treatment capacity of industrial sewage facilities in China in 2015 is 90.265 billion tons / year, and the actual treatment capacity is 44.45 billion tons / year. At the level of "quantity", it can meet the actual needs. But at the same time, we also need to see that the actual treatment capacity of industrial sewage is far greater than the actual discharge capacity, because there are more industrial sewage to be reused after treatment, and in most cases, the discharge standard for reuse is even higher than the discharge.  

The pollutants in industrial sewage are complex, so it is difficult to meet the discharge requirements through a single treatment method at one time. It is often necessary to carry out wastewater treatment through a combination of multiple ways. The types and concentrations of pollutants discharged by different types of industrial enterprises are quite different, even for the same industry, due to different processes, the sewage

2. Industry scale and development prospect

Industry scale

As for the whole wastewater treatment industry, under the guidance of national policies, the increase of treatment demand caused by serious water pollution, and the breakthrough of water treatment technology effectively improve the efficiency of wastewater treatment, China's water treatment industry will continue to maintain a high-speed growth. CIC predicted that the market size of the whole water treatment industry in China will reach 280 billion yuan in 2017, with an annual compound growth rate of 43.25% in the next five years (2017-2021), and 1179 billion yuan in 2021.  

Specifically in the field of industrial sewage treatment, under the shock of unprecedented supervision and punishment of the state, a large number of industrial enterprises will reduce the cost of sewage discharge through the upgrading of sewage standards, while the third-party operation of industrial water treatment is fully spread out, which is expected to bring rapid market volume.  

According to Polaris environmental protection network, compared with urban sewage treatment, the proportion of industrial wastewater treatment in China is still low, and there is a great space to improve the proportion in the future. China's industrial wastewater treatment market alone will reach about 200 billion yuan per year in the future.   

From the perspective of region, we pay more attention to zero discharge of industrial wastewater in Inner Mongolia, Xinjiang, Shaanxi, Ningxia and other regions. In terms of industry, petrochemical industry, coal chemical industry, power plant and some industrial parks pay more and more attention to zero emission. With the gradual strengthening of environmental awareness and the implementation of relevant laws and regulations, the zero emission market of papermaking, steel, petrochemical, coal chemical industry and other industries will have a strong growth in the future.  

(2) industry development trend and Prospect

At present, China's water treatment industry is in a period of rapid growth. In the future, it will gradually usher in a broader market. According to the prediction of China water network in China water industry policy and market analysis, urban sewage will become the top priority of sewage treatment. "From 2010 to 2015, the investment demand of China's urban sewage treatment industry is 700 billion yuan (including 150 billion yuan of sludge treatment investment), with an average annual increase of 110 billion yuan; the investment of sewage recycling is 30 billion yuan." China's sewage treatment will maintain a high growth in the next 10 years. In the future, the main development trends of the industry are as follows:

① the discharge standard of industrial wastewater is improved, and the trend of centralized treatment is obvious

The 12th Five Year Plan for energy conservation and emission reduction points out that the areas with dense population and relatively concentrated sewage discharge adopt centralized treatment, and the construction of specialized industrial parks can reduce the difficulty of pollution supervision and treatment in the decentralized layout, which is conducive to the centralized treatment of industrial wastewater. In the future, the construction of specialized industrial parks will become a new model for the development of industry and environmental protection in various regions. The trend of centralized treatment of industrial wastewater will further expand the market capacity. At the same time, higher requirements will be put forward for the technology, process and design scheme of wastewater treatment enterprises.  

② the demand for urban wastewater treatment and reuse is growing rapidly

According to the statistical bulletin of urban and rural construction in 2016 issued by the Ministry of housing and urban rural development, at the end of 2016, there were 2039 sewage treatment plants in cities nationwide, an increase of 95 over the previous year, with a daily treatment capacity of 149100 cubic meters, an increase of 6.2% over the previous year, and a drainage pipeline length of 577000 kilometers, an increase of 6.9% over the previous year. The total amount of urban sewage treatment is 44.88 billion cubic meters, and the urban sewage treatment rate is 93.44%, an increase of 1.54 percentage points over the previous year, of which the centralized treatment rate of sewage treatment plant is 89.80%, an increase of 1.83 percentage points over the previous year. The daily production capacity of urban reclaimed water is 27.62 million cubic meters, and the consumption of reclaimed water is 4.53 billion cubic meters. China's national economy continues to grow rapidly, the integration of urban and rural areas, the sustainable development of industrialization, the rising trend of urban population, the per capita water resource share is decreasing year by year, the demand for sewage treatment is growing rapidly. According to the rough calculation of the amount of untreated sewage in 2016 and the marginal treatment capacity of new sewage treatment plants, 118 sewage treatment plants and supporting drainage pipelines are still to be built in China, about 33400 km.

③ old industrial wastewater treatment needs to be improved

According to the 2018 China Statistical Yearbook issued by the National Bureau of statistics, the total amount of waste water discharged in 2017 was 69.966 billion tons, including 23.916 billion tons of industrial waste water discharged from 31 major cities. According to the 12th Five Year Plan for the development of energy conservation and environmental protection industry, during the 12th Five Year Plan period, we will focus on membrane treatment, new biological denitrification, prevention and control of heavy metal wastewater pollution, advanced treatment technology of high concentration and refractory organic industrial wastewater, and promote efficient energy conservation, gas exposure and upgrading of sewage treatment plants. According to the spirit of the above documents, ammonia, nitrogen, etc. are listed as important emission reduction binding indicators for energy conservation and emission reduction, the emission standards of relevant industry enterprises are further improved, and the technical requirements for wastewater treatment of newly-built and expanded industrial enterprises and industrial sewage plants are gradually increased.  

④ black and odorous water and river basin treatment have entered the stage of centralized treatment, and the market demand for ecological restoration is clear

In April 2015, the action plan for prevention and control of water pollution was officially issued, which clearly stated that by 2020, the black and odorous water bodies in cities at prefecture level and above should be controlled within 10%, and by 2030, the black and odorous water bodies in cities should be eliminated. Since then, the regulation of black and smelly water in the city has officially started. In September 2015, the Ministry of housing and urban rural development and the Ministry of environmental protection jointly issued the guidelines for the remediation of black and odorous water bodies in cities, which became the first supporting rules of the "ten water rules". In December 2016, the general office of the Central Committee of the Communist Party of China and the general office of the State Council issued the opinions on the comprehensive implementation of the river chief system. Local Party committees and governments at all levels should make the implementation of the river chief as an important measure to promote the construction of ecological civilization, practically strengthen organizational leadership, pay close attention to the implementation of responsibilities, promptly formulate and issue work plans, and clearly define the work schedule. By the end of 2018, the river chief system will be fully implemented Establish a river director system; with the local governance gradually entering the substantive stage, the black and Odorous River governance enters the centralized remediation stage, which will drive the total investment of black and odorous water treatment to exceed 450 billion yuan. During the 13th Five Year Plan period, the demand for black and odorous water treatment is expected to be released in a centralized way.  

⑤ the market scale of industrial water system tends to be stable, and the centralized treatment of industrial parks is the development trend

In January 2015, the new environmental protection law was formally implemented. Compared with the old environmental protection law, the new environmental protection law emphasizes the total emission control. For areas exceeding the national emission indicators, the approval of the environmental impact assessment documents for construction projects with the total emission of new key pollutants was suspended. For the enterprise side, the illegal cost of the enterprise will be greatly increased through the policy of "daily continuous punishment", and the illegal driving force of the enterprise and the person in charge of the enterprise will be reduced by imposing administrative and criminal penalties on the relevant person in charge of the enterprise, the government and the third-party organization. Under the pressure of environmental policy, the transformation of industrial structure and the upgrading of energy structure become the inevitable choice of China's supply side reform.  

With the development of local economy and the need of environmental treatment, many provinces and cities have put forward the industrial development strategy of "leaving the city and entering the park", which increases the centralized control and treatment of the pollution of the enterprise groups in the industrial park, and the water treatment service also develops from the point source of a single enterprise to the systematic treatment of the whole park, as well as the comprehensive utilization of water resources. With the number and scale of industrial parks With the expansion of industrial wastewater treatment standards, the comprehensive water treatment business in the industrial park will have a huge market space.
