Eliminate Bad Class V Water Zhejiang Will Carry out "Five Water Governance" to the End

3# May 22 is "World Water Day". On the morning of that day, the provincial party committee and the provincial government held a provincial water pledging conference to eliminate bad Class V . Xia Baolong, Secretary of the Provincial Party Committee and Director of the Standing Committee of the Provincial People's Congress, stressed at the meeting that departments at all levels should resolutely, resolutely win the war of extermination of inferior Class V water, unswervingly push the "five water governance" into depth, and take practical actions to create a beautiful Zhejiang model of China.

Adhere to the High Standard of Full Coverage

According to the requirements clearly put forward by the provincial party committee, the whole province will completely eliminate inferior Class V water this year. To fight the war of extermination of inferior Class V water, we must first win the war of extermination of inferior Class V water quality sections 33 in the whole province, and go up the river and drive straight in, pushing the "extermination war" deep into the creek ditch, and improving the water quality in an all-round way. Provincial control and city control sections are the top priority in eliminating inferior Class V water. They should be used as a breakthrough to "eliminate inferior" and take the lead in getting through and giving priority to getting through. At present, the number of sections with inferior grade v water quality in the province has been reduced to 6 . The number of sections with inferior grade v water quality controlled by the city has been reduced to 27 , and 70% is distributed in Wenzhou and Taizhou plain river networks. In order to make the people feel the changes in water quality, they should not only pursue the elimination of inferior Class V water on the cross section, but also achieve the goal of eliminating inferior Class V water throughout the territory, that is, all water bodies must eliminate inferior Class V water.

is the "landmark battlefield" of "five water governance". Eliminating inferior Class V water is only the basic requirement and bottom line goal. According to this requirement, the areas that have eliminated the inferior category V water should not only do a good job of consolidating the article, but also do a good job of upgrading the article. To improve the water quality in an all-round way, we should not relax and be careless. We should focus on the four links of "interception, cleaning, treatment and repair", so as to realize the whole process, whole system and all-round treatment from sewage source control, sewage treatment, sludge cleaning to water body restoration.

Pushing Forward Six Major Projects

2016 12 , the General Office of the Provincial Government issued the "Zhejiang Province Action Plan for the Elimination of Class V Water". According to this plan, our province takes improving the quality of the water environment as the core and comprehensively implements the "six major projects" to eliminate inferiority ".

sewage interception and containment works. Comprehensively strengthen the construction of urban sewage collection and treatment capacity, effectively improve the sewage treatment rate, sewage treatment plant operating load rate and discharge rate, and make every effort to improve the level of urban sewage treatment. Strengthen the daily maintenance of urban drainage and sewage collection pipe network, and strive to solve the outstanding problems such as leakage, damage, wrong connection and mixed connection of sewage pipe network. Strengthen the diversion transformation of the existing rain and sewage confluence pipe network, carry out the transformation of balcony drainage pipes in residential areas, and promote the initial collection, treatment and resource utilization of rainwater in areas where conditions permit. Strengthen the construction of facilities for the collection and treatment of pollutants from ships in ports and wharves.

River dredging works. According to the differences of silt composition, water characteristics and other factors, scientific and reasonable selection of dredging methods; encourage the selection of ecological and environmental dredging methods, realize the integration and process of ecological dredging, silt dehydration, garbage separation, residual water circulation treatment, and improve the scientific level of dredging. Gradually establish a rotating dredging mechanism to achieve a dynamic balance of silting and dredging in rivers, lakes, reservoirs and ponds.

Industrial Remediation Works. In strict accordance with the idea of cultivating a number of demonstration enterprises, gathering a number of small and scattered enterprises, and reducing a number of critical enterprises and the standards for the improvement of key industries, we will further promote the improvement of heavy pollution and high energy consumption industries. Vigorously carry out the rectification and upgrading of key industries with local characteristics such as pickling and sand washing, as well as the special rectification of backward enterprises, processing sites, and workshops that have a greater impact on the water environment. Deepen the "vacating cages for birds", focusing on "four noes" enterprises (workshops) such as unlicensed operations, no safety guarantees, no legal places, and no environmental protection measures, and accelerate the elimination of outdated production capacity. Centralized control of water pollution in industrial agglomeration areas such as economic and technological development zones, high-tech industrial development zones, and export processing zones. By the end of 2017 , all industrial agglomeration areas will have built centralized sewage treatment facilities and installed automatic online monitoring devices as required. Strictly implement the pretreatment and quality treatment of heavy metals and high-concentration refractory wastewater in heavy pollution industries, promote open-pipe transportation of wastewater in key industries, strengthen the diversion of rain and sewage and clean-up in enterprises, and strengthen the operation and maintenance management of pollution control facilities in enterprises. Strengthen water recycling and improve water use efficiency.

Agricultural and rural non-point source management project. Strictly implement the system of prohibited and restricted areas, and further improve the level of refinement and standardization of pollution prevention and control in retained farms. We will continue to promote the reduction of chemical fertilizers and pesticides to increase efficiency and reduce agricultural non-point source pollution. Improve the construction of beautiful villages to ensure the centralized and effective collection and disposal of household waste in the villages and the classification and disposal of household waste.

Outlet Remediation Works. Strengthen the examination of the setting of sewage outlets into the river, and standardize the setting of sewage outlets into the river in accordance with the law. Comprehensively publish the information on the list of sewage outlets set up in accordance with laws and regulations, establish an information management system for sewage outlets into the river, and comprehensively clean up sewage outlets that are illegally set up, set up irrationally, and still cannot meet the discharge standards after rectification. All sewage outlets and hidden pipes that are secretly or privately set shall be blocked. For direct sewage discharge outlets, all nearby pipes shall be taken or temporary sewage interception measures shall be taken. For rain and sewage mixed discharge outlets, rectification shall be made within a time limit.

Ecological water distribution and restoration project. In accordance with the requirements of introduction, flow and discharge, enhance the mobility of water bodies, improve the self-purification capacity of water bodies, and build a good water ecosystem. Open up the Broken River and gradually restore the natural connectivity of various water bodies such as ponds, rivers and lakes, and wetlands. Fully consider the basic ecological water demand, maintain a certain water surface rate, reasonable flow of rivers and reasonable water levels of lakes and reservoirs, and maintain the ecological health of rivers and lakes.
