造成水体黑臭的主要原因有:外源污染、污水直排、面源污染、内源污染、底泥释放、自净能力差、缺乏长效机制。
The main causes of black odor are: external pollution, sewage direct discharge, non-point source pollution, endogenous pollution, sediment release, poor self-purification capacity, lack of long-term mechanism.
外源污染主要包括城市污水直排、工业废水偷排、合流制管网溢流污染、城市初期雨水、农业面源及沿岸乱扔的垃圾等
Exogenous pollution mainly includes direct discharge of municipal sewage, stolen discharge of industrial wastewater, Overflow Pollution of combined pipe network, rainwater in the early period of city, agricultural non-point source and litter littering along the coast.
针对污水直排治理措施:截污纳管:末端截污或源头截污、直排口污水原位处理、旁路一体化设备处理。
For sewage treatment measures: sewage interception pipe: end or source of sewage interception, sewage treatment in situ, bypass integrated equipment treatment.
针对面源控制治理措施:海绵城市措施:植被缓冲带、雨水花园等、初期混合水调蓄池、人工湿地
Control measures for non-point source: sponge city measures: vegetation buffer zone, rainwater garden, initial mixed water storage tank, constructed wetland
内源污染主要包括河底底泥释放、水生植物腐烂等
The internal pollution mainly includes sediment release from the bottom of the river and decay of aquatic plants.
针对内源污染治理措施:清淤疏浚、生物底改、水生植物残体清理;
The measures to control the internal pollution include dredging and dredging, biological bottom alteration and aquatic plant residue cleaning.
自净能力差主要包括水动力不足,流动性差、缺氧、水生态系统脆弱等等
Poor self purification capacity mainly includes inadequate hydrodynamic, poor mobility, anoxia, fragile aquatic ecosystems, etc.
针对自净能力差治理措施:人工增氧、混凝沉淀、微生物强化净化、生态浮岛、水生态系统构建、水华藻类控制、水生生物恢复、清水或再生水补给。
In view of the poor self-purification measures: artificial oxygen, coagulation and sedimentation, microbial enhanced purification, ecological floating island, aquatic ecosystem construction, algae control, aquatic biological restoration, clean water or recharge of reclaimed water.
缺乏长效机制主要为部门职能存在冲突,管理不到位等;由于以上一种或多种原因综合的结果,导致水体黑臭。
The lack of long-term mechanism is mainly due to the conflict of departments'functions and the inadequate management, etc. As a result of one or more of the above reasons, resulting in the black and stinky water.
针对缺乏长效机制措施:加强水体管理,实施“河长制”,实施“一河一策”、水质成效考核付费、增加执法力度,杜绝偷排污水、健全监测体制。
In view of the lack of long-term mechanisms and measures: to strengthen water management, the implementation of the "long River system", the implementation of the "one river one policy", water quality assessment and payment, increase law enforcement efforts, stop the illegal discharge of sewage, improve the monitoring system.
