Three-year action plan for improving the quality and efficiency of sewage treatment

3. Strengthen the standardization of sewage pumping stations. Focus on the improvement of transfer capacity, and promote the standardized construction and intelligent operation of sewage pumping stations (Wells) in accordance with the requirements of "advanced technology, safety and reliability, unified standards, and economic and reasonable". The construction of new sewage pumping stations with high standards, the current sewage pumping stations through investigation and evaluation, classification and implementation of capacity improvement or upgrading, 152 new or upgraded sewage pumping stations. Unify the selection and configuration standards of key equipment and facilities of sewage pumping stations, implement dual-circuit power supply transformation or equip standby power facilities, improve basic functions, enhance versatility and interoperability, add water quality and water quantity monitoring facilities at key node pumping stations, coordinate the promotion of water supply and drainage zoning metering, strengthen water balance analysis, and help sewage collection.

4. Strengthen the emergency response capacity of the sewage system. Focusing on the improvement of the toughness of the system, fully considering the impact on the operation of the sewage treatment plant caused by fluctuations in the amount of water coming into the plant, extreme low temperature, single tank maintenance, sewage pipe network and treatment system accident emergency, actively promote the construction of inter-plant and inter-regional interconnection pipelines in the sewage collection section, break administrative barriers, strengthen the overall planning of the interconnection pipeline system at the city level, and actively explore regional collaboration. Construction of 82.3 kilometers of sewage interconnection network. Strengthen the engineering and management measures for sewage collection, treatment and other facilities to effectively cope with overload, extremely low temperature, power loss, construction accidents, meteorological disasters and other factors, improve operation scheduling plans and emergency plans, strictly prohibit reduced operation, do relevant training, exercise, assessment, supervision and evaluation, and improve anti-risk ability.

5. Strengthen the standardized treatment and disposal of sludge. Focusing on the safe disposal of sludge, coordinating the construction of comprehensive utilization or permanent treatment and disposal facilities for sludge and municipal waste in sewage treatment plants, rationally arranging and constructing pipeline network drainage sludge disposal facilities, building 7 new and upgraded facilities, increasing the treatment and disposal capacity of 320 tons/day, and gradually improving the mutual guarantee system for sludge treatment and disposal in the municipal area. A traceable supervision system for the whole process of sludge transport, treatment and disposal has been established, GPS dynamic tracking instruments have been installed on all sludge transport vehicles and vessels, and the whole process and all-round supervision of sludge transport have been implemented online.

6. Improve the effectiveness of rural domestic sewage treatment. Focusing on the comprehensive treatment of agricultural pollution, promoting the extension of urban sewage treatment facilities and services to the countryside, the villages close to the municipal sewage network in principle adopt the takeover method, and carry out sewage treatment for 862 untreated natural villages, and strive to achieve 100% of the city's rural domestic sewage treatment rate. Evaluate the existing facilities, upgrade degraded and backward facilities, independent facilities of Taihu Lake and Yangcheng Lake first and second level protection areas, key national and provincial examination sections of villages, can not meet the effluent water quality requirements, priority to take over the transformation and upgrading. Implement unified operation and maintenance at the county and district levels, strengthen long-term management, improve the level of information supervision, strengthen daily assessment and supervision, and ensure the normal operation of facilities and discharge of water up to standard.

(2) Implementing the construction project of areas where the quality and efficiency of sewage treatment meet the standards.

Seven. Eliminate sewage direct discharge and mixing outlet. Further find out the drainage of farmers' markets, small restaurants, night stalls, farmers' music, barber shops, baths, auto repair and car washing, laundry, small clinics and other "small scattered" drainage households and construction sites, waste transfer stations, water quality, pretreatment facilities and take-over, establish a list of problems and a list of tasks, timely remediation, and according to the requirements of the classification of drainage permits or sewage acceptance procedures. In urban built-up areas, we will carry out inspections of non-rain outfalls, drainage outfalls into rivers, drainage outfalls in hidden culverts, and intercepting pipes along rivers, scientifically eliminate the miscombination of rain and sewage pipes and direct sewage outfalls, effectively control the overflow pollution of combined drainage systems during rainy days, and eliminate sewage from entering river headwaters.
