摘要
我国已进入2020年基本消除城市黑臭水体的关键时期,为打赢、打好这场污染防治攻坚战的"标志性"战役,党中央和国务院近期提出了污水处理"提质增效"三年行动计划,旨在进一步指导和督促各地采取有效、对路、符合实际的措施,从根本上解决导致黑臭的核心问题。"提质增效"三年行动计划的重点是针对污水收集系统,就是在深入调查的基础上,重点解决污水直排、清污不分、排水管道旱天满管流、污水处理厂进水浓度低、管道积泥多等问题。实现污水不进河、清水不进管、溢流少污染,支撑消除城市黑臭水体整治和巩固提升整治成效。
China has entered the crucial period to eliminate the urban black and odorous water bodies by 2020.To win the battle of pollution prevention and control,the Party Central Committee and the State Council have proposed a three-year action plan to improve the quality and efficiency of the urban drainage system,providing the guidelines for local governments to take effective and practical measures.The three—year action plan focuses on the problems solving in the sewerage system based on the complete investigation,including the sewage direct discharge,mixed flow of clean and dirty water,full-section pipe-flow of drainage pipes in the dry season,low pollutants concentration of the influent in wastewater treatment plant and accumulated sludge in the pipelines.This paper summarized the strategies and methods in avoiding the sewage into the river,preventing the clean water into sewers and reducing overflow pollutants,thereby enhancing and consolidating the remediation effect of black and odorous water bodies.
