With the implementation of the national environmental protection industrial policy, the water treatment industry has achieved some results in "total amount control", but from the perspective of "quality control", there is still a long way to go. The market scale in the fields of advanced treatment of drinking water, upgrading and reconstruction of sewage and reuse of sewage and wastewater is very broad

I. in the field of advanced treatment of drinking water

China's current drinking water standard is the new version of the hygienic standard for drinking water (GB), which is fully implemented from July 1, 2007 and enforced from July 1, 2012. In 2011, the urban water supply quality monitoring center of the Ministry of housing and urban rural development, together with relevant units, organized national recognized professional water quality testing institutions to conduct sampling tests on the factory water of waterworks, which accounts for 80% of the national urban public water supply capacity. According to the evaluation of the new "sanitary standard for drinking water", the water quality standard rate of the waterworks is 83%

the process of urbanization is inseparable from their respective mother river systems, and the attention and understanding of water quality is also an important part of the development of human civilization. Generally speaking, the development of water quality standards can be divided into three stages: health, safety and health. We have gone through the sanitation stage, and now we are in the stage of water quality safety. The concept of health is budding and developing. From 2016, cities at and above the prefecture level and some qualified county-level units need to regularly publish the quality information of centralized drinking water sources, of which the former needs to be disclosed every month and the latter needs to be disclosed every quarter

in this context, Shanghai, Hangzhou, Shenzhen and other places across the country have formulated and issued the action of raising the standard of drinking water to meet the standard, and improved the existing drinking water standards. On the one hand, it is to guide water supply enterprises to improve the requirements of drinking water quality; On the other hand, it is also a powerful measure for the competent government departments to respond to the urgent concerns of the public about drinking water safety and strengthen government supervision. The above measures of local governments have a strong demonstration effect. At present, many regions have introduced relevant measures, which has promoted the rapid growth of the drinking water advanced treatment market

Second, in the field of advanced sewage treatment

in recent years, with the increase of water environmental pressure, China's sewage treatment and discharge standards have been continuously improved

in 2015, the Ministry of environmental protection of the people's Republic of China issued a draft for comments on Revising the national environmental protection standard, the discharge standard of pollutants from urban sewage treatment plants (GB). According to the requirements of environmental protection, in areas where the density of land development has been high, the environmental carrying capacity has begun to weaken, or the environmental capacity is small, the ecological environment is fragile, and serious environmental pollution problems are prone to occur, requiring special protection measures, The discharge of pollutants should be strictly controlled, and special discharge limits of water pollutants should be implemented in urban sewage treatment plants in the above areas. Some control items in the "special discharge limit" have reached the surface class IV water standard. In addition, Beijing, Tianjin, Jiangsu, Zhejiang, Anhui and other places have issued local sewage discharge standards, which are stricter than the current national standards

Weber consulting learned that in 2017, China's urban sewage treatment rate has reached 94.54%, and the county sewage treatment rate has reached 90.21%. From the perspective of sewage treatment rate, it has reached the requirements of the 13th five year plan. However, at present, the national discharge standards for sewage treatment plants have been gradually improved, and the discharge standards of more and more urban sewage treatment plants have been upgraded from class II and class I B standards in the original "pollutant discharge standards for urban sewage treatment plants" GB to class I a or higher standards. In order to reach a higher discharge standard, he attributed the sales growth of sewage to two new products: two plate DP series products and A5 series servo injection molding machine, otherwise it will have a negative impact on instrument optical parts and metal coating. The upgrading and transformation of the treatment plant is imminent

according to the data released by the Ministry of housing and urban rural development, in 2017, there were 2209 sewage treatment plants in cities alone, with a total treatment capacity of 157.43 million cubic meters/day. In order to promote the implementation of the requirements of the "ten water" task, the Ministry of ecological environment has established a list of centralized sewage treatment facilities covering all the treatment scale of 0500 cubic meters/day and above. At present, the "national list of centralized sewage treatment facilities" has been published, of which the first batch of lists covers 998 centralized sewage treatment facilities in Shanghai, Fujian, Guangdong, Gansu and Ningxia, with a total daily treatment capacity of more than 44.25 million cubic meters, The list defines the emission standards to be implemented by the end of 2020 and the actual emission standards currently implemented. Among them, the treatment scale facing standard upgrading (the discharge standard to be implemented by the end of 2020 is higher than the current discharge standard) is more than 30.38 million cubic meters/day, accounting for about 68%. The market increment of advanced water treatment brought by the demand for sewage upgrading and reconstruction is considerable

III. in the field of reclaimed water, reclaimed water and resource utilization

"the pollution caused by the plastic granulator process in the 13th five year plan is often an important source of environmental pollution in China." the national plan for the construction of urban sewage treatment and recycling facilities points out that China should further plan as a whole, make reasonable layout, increase investment, and realize the transformation of urban sewage treatment facilities from "scale growth" to "quality and efficiency improvement", The transformation from "sewage treatment" to "recycling" will comprehensively improve the guarantee capacity and service level of China's urban sewage treatment facilities, so that people can truly feel the effectiveness of the improvement of water environment quality

at present, reclaimed water in China is in its infancy, and Beijing Tianjin Hebei region is relatively ahead of it. As of 2017, the utilization rate of renewable water resources in Beijing Tianjin Hebei region has exceeded 35.0%, while that in other cities and counties is less than 5%. The 13th five year plan for the construction of national urban sewage treatment and recycling facilities requires that during the 13th Five Year Plan period, the scale of renewable water use facilities will be increased by 15.05 million tons/day, including 12.14 million tons/day in cities and 2.91 million tons/day in counties. The development and utilization of renewable water has ushered in a market opportunity for rapid development

sewage and wastewater recycling is to extract valuable resources such as water and salt from sewage and wastewater through deep processing, so as to realize the resource utilization and commercial value of valuable things in water, turn waste into treasure, make full use of things, and recycle resources. Resource utilization has higher requirements and greater challenges for technology and process. Scientific and technological innovation and cross-border achievements in the environmental protection and water industry have accelerated the development of the sewage and wastewater resource market and the development of new material testing, verification and performance evaluation service platform. Therefore, the new water market came into being. The new water uses the advanced technology of ultrafiltration and reverse osmosis to process domestic sewage and industrial wastewater into high-quality reclaimed water, which meets the drinking water standard or high-quality industrial water. At present, relevant national departments and industrial circles are exploring new models for the development and utilization of fresh water

wastewater recycling is the fundamental way to solve the shortage and pollution of water resources. The root of water environmental problems lies in sewage. The construction of sewage recycling system is an important guarantee for the sustainable development of towns and industries
