the 11th golden week slipped away quietly in "shopping, eating and eating". although we hope our motherland will have another lunar birthday, we still have to accept the fact that we have already started work. dream (pin) thinking (poor) makes me full of motivation!
several water treatment policies have been implemented during the holidays that have just passed, and some will be implemented in the next two months of this year.
"three-year action plan for improving quality and increasing efficiency of urban sewage treatment in guangzhou city, guangdong province (2019-2021)"
had passed the standing meeting of guangzhou municipal government
according to the action plan, by the end of 2021, the blank areas of domestic sewage collection and treatment facilities in built-up areas will be basically eliminated, and the centralized collection rate of urban domestic sewage will reach 80%, basically realizing the lawful access and discharge of domestic sewage in residential districts, organs and institutions. sixteen sewage treatment plants in the city will strive to be completed and operated by the end of march 2020.
_the action plan proposes that we will speed up the construction and management of sewage collection and treatment, improve drainage management system, fill the management vacuum of drainage households, realize the equal emphasis of "scale growth" and "quality improvement" of sewage collection and treatment, and ensure that it takes about three years to improve the quality and efficiency of urban sewage collection and treatment.
by the end of 2019, the municipal sewage treatment capacity will reach 6.87 million tons per day, the centralized collection rate of municipal domestic sewage will reach 74.5%, the average concentration of biochemical oxygen demand (bod) in the influent of municipal sewage treatment plant will reach 105 mg/l, and the average concentration of ammonia nitrogen in the influent will reach 21.7 mg/l; by the end of 2020, the municipal sewage treatment capacity will reach 7.7 million tons per day, and the municipal domestic sewage will reach 7.7 million tons per day. the centralized collection rate reached 76%, the average concentration of biochemical oxygen demand in municipal domestic sewage treatment plant reached 110 mg/l, and the average concentration of ammonia nitrogen reached 23.6 mg/l. by the end of 2021, the blank area of domestic sewage collection and treatment facilities in the built area was basically eliminated, and the centralized collection rate of municipal domestic sewage reached 80%, and the average concentration of biochemical oxygen demand in municipal domestic sewage treatment plant was striving to reach 120 mg/l.
the action plan proposes to speed up the construction of "intelligent drainage" information system, install on-line monitoring equipment at important nodes and key gates of drainage network, and establish a dynamic "drainage network operation chart" which can real-time feedback the operation status of drainage network combined with "one map of drainage facilities".

regulations on river management of ningbo city
entered into force on october 1, 2019
in order to strengthen river management, ensure flood control safety and smooth drainage, protect water ecological environment, and give full play to the comprehensive functions and benefits of the river, it is urgent to revise the regulations on river management of ningbo city.
on april 26, 2019, the regulations on river management of ningbo city were amended by the 20th meeting of the standing committee of the 15th ningbo people's congress, approved by the 13th meeting of the standing committee of the 13th zhejiang people's congress on august 1, 2019, and formally implemented on october 1, 2019.
the revised regulations on river management of ningbo city focus on the two major objectives of "no reduction of river area and continuous improvement of river ecosystem", further clarify the responsibilities of river management of government departments, highlight the control and management of river waters, and strengthen the protection of river ecological construction.
adding new contents such as determination of basic water surface rate, drainage management and joint law enforcement and supervision by departments to ensure that the area of river waters does not shrink, function does not decay and ecology does not degenerate, and intensifying the "co-governance of water banks" to further enhance the river water safety and water environment carrying capacity.
the key contents of the revision of the regulations are as follows:
firstly, according to the requirements of this round of government reform, the division of duties and responsibilities for river management of relevant departments should be adjusted and clarified.
the second is to improve the compilation subject, content and procedure of river professional planning.
third, highlight the control of the basic water surface rate of the river, and make it clear that the basic water surface rate of the river should be taken as the planning index of the development and construction land of the block.
fourth, to divide the management scope of different types of rivers and consolidate the foundation of river management.
fifth, strengthen source control, explicitly prohibit the direct discharge of all kinds of sewage without sewage treatment facilities into rivers, and timely dismantle, block or transform existing sewage outlets and rain-polluted mixed outlets;
sixth, strengthen the responsibility of ecological water diversion and recharge of rivers, clarify the relevant plans formulated by the water administration department, promote the flow of river water and improve the water quality of rivers;
seventh, we should strengthen government responsibility and make it clear that the municipal and district (city) people's governments should report to the standing committee of the people's congress at the same level in the first quarter of each year on the safety of river flood discharge, the control of basic water surface rate, sewage discharge and sewage treatment in the previous year.
technical standards for rural domestic sewage treatment
entered into force on december 1, 2019
recently, the ministry of housing and construction issued the new rural domestic sewage treatment technology standard, which will be implemented on december 1, 2019.
the basic framework of "new technologies standard for rural domestic sewage treatment" includes general principles, terminology, basic regulations, design water quantity and quality, sewage collection, sewage treatment, construction acceptance, operation and maintenance management, etc.
main highlights of the technical standard:
1. determine the treatment method of rural sewage.
according to the current rural demand and technological maturity, combined with the requirements of "water ten articles", the county is the unit.
"standards" suggest that the county administrative region as a unit to implement unified planning, unified construction, unified operation and unified management.
in addition, drawing on the experience of centralized and decentralized treatment of rural sewage at home and abroad, the treatment methods of domestic sewage treatment, centralized treatment of rural sewage, urban sewage treatment and other urban sewage pipe networks are put forward. on the basis of comprehensive economic comparative analysis of construction, operation, maintenance and management of rural domestic sewage treatment, appropriate treatment methods and technological processes should be selected according to local conditions.
2. design water quantity and quality. the differences of rural living habits, living standards, climatic conditions, water sources and water resources structure in different areas lead to great differences in sewage discharge and water quality in rural areas, which makes it difficult to give specific design values. the data range listed in the standard is for local reference only in the absence of basic data. field investigation should be the first choice to determine rural sewage discharge and water quality.
3. emphasize the important role of rural sewage collection network. at present, rural sewage treatment emphasizes the lack of technology and collection system. in the past, most of them referred to the design of urban drainage network, which resulted in a large amount of waste of investment. in the "standard", some requirements are put forward, and it is suggested that the diameter and flow rate of pipeline should be determined according to displacement and slope, and the management regulations of pipeline and inspection well should be formulated.
4. technical parameters optimization of rural sewage treatment. this standard optimizes the specific process parameters to adapt to the characteristics of rural sewage in china. the main basis of optimization includes summing up the experience of domestic projects in recent years, drawing lessons from foreign experience, and putting forward the requirements for toilet sewage treatment and resource utilization in view of toilet renovation.
