摘要:- 在消除水體黑臭的過程中，合流制溢流(CSO)污染不容忽視。如何實(shí)現(xiàn)溢流頻次大幅度減少和削減入河污染量，是CSO污染控制的關(guān)鍵。詳盡分析黑臭水體的現(xiàn)狀問題和成因，制定合理的CSO控制目標(biāo)和技術(shù)路線，比選多目標(biāo)多階段下的工程措施，才能給出切實(shí)可行的治理方案。以重度黑臭水體浯溪為例，梳理國內(nèi)外CSO污染控制有效做法，根據(jù)浯溪特點(diǎn)和問題成因，以治理目標(biāo)和技術(shù)思路為指引，統(tǒng)籌末端出口截流、調(diào)蓄池建設(shè)、污水處理和生態(tài)設(shè)施等工程，經(jīng)模型優(yōu)化比選得出最佳實(shí)施方案。結(jié)合合流改造工程開展動(dòng)態(tài)評(píng)估，制定近遠(yuǎn)期工程措施，實(shí)現(xiàn)浯溪CSO污染得以有效控制和消除黑臭長制久清。
Abstract:- In the process of eliminating black and odorous water body, the pollution of combined sewer overflow(CSO) can not be ignored. How to reduce the overflow frequency and reduce the amount of pollution into the river is the key of CSO pollution control. This paper analyzes the current problems and causes in detail, formulates reasonable CSO control objectives and technical routes, compares and selects engineering measures under multi-objective and multi-stage, and gives feasible treatment scheme. Taking Wuxi River as an example, the effective methods of CSO pollution control at home and abroad are summarized. According to the characteristics and causes of Wuxi River, the treatment objectives and technical ideas are taken as the guidance. With the coordination of outlet interception, the construction of storage tank, sewage treatment and ecological facilities engineering, the best implementation scheme is obtained through model optimization and selection. Combined with the confluence reconstruction project, the dynamic evaluation was carried out, and the short-term and long-term engineering measures were formulated to effectively control and eliminate the black-odor and long-term pollution.
