苏州市长桥街道北片区生活污水处理提质增效达标区工程设计

Engineering Design of Domestic Sewage Treatment Quality Improvement and Efficiency Up-to-Standard Area in North Changqiao Street, Suzhou

摘要:

长桥街道北片区生活污水处理提质增效“333”达标区工程总面积约665.92 hm2，达标区块内共有11条河道，234个雨水排口，其中36处雨水排口存在晴天出流现象。经排查，对存在雨污混接问题的20个小区进行雨污分流改造，工程投资约8 000万元，工程建设完成后解决了长桥街道北片区污水入河问题，改善了长桥街道北片区河道水质，为其他地区开展污水提质增效达标区建设提供了示范意义。

Abstract:

The total area of the domestic sewage treatment quality improvement and efficiency "333" up-to-standard area project in the north section of Changqiao Street is about 665.92 hm2. There are 11 rivers and 234 rainwater outlets in the up-to-standard area, in which there are discharge phenomena in 36 rainwater outlets in sunny days. Through investigation, there are 20 communities with the problem of mixing the rainwater and sewage, which will be reconstructed for the separation of rainwater and sewage. The engineering investment is about 80 million yuan. After the completion of the project, the problem of sewage flowing into the river in the north section of Changqiao Street is solved. The water quality of the river in the north section of Changqiao Street has been improved, which provides the demonstration significance for the construction of sewage quality improvement and efficiency up-to-standard areas in the other regions.
