【摘要】：平顶山市区目前的排水体系基本采用分流排水体制,现建有污水处理厂和提升泵站各一座即第一污水处理厂和第一污水泵站。根据平顶山市排水系统总体发展规划及调整,需要建设第二污水处理厂,近期工程为2012年,远期工程为2020年。本工程服务范围为神马大道与湛南路以南,光明路以东,南三环路以北,神马路以西,服务面积约29.6km2。第二污水处理厂收水范围规划为二个区,分别是铁东区和铁西区。近期服务面积约14.6km2。铁东区距拟建的第二污水厂较近,处于沙河下游,规划为高新工业园区,工业园区内以轻度污染和无污染的高科技企业为主;铁西区距老城区较近,处于沙河上游,规划以商住区为主。根据平顶山市排水工程现状,城市污水量预测近期污水量40万吨/日,远期60万吨/日。第一污水处理厂设计总规模为日处理污水25万吨。2000年12月完成一期工程,日处理量为15万吨,污水处理后排入湛河,二期工程日处理污水10万吨于2005年底建成并已经投入运营,目前一厂已经满负荷运行。规划排水体制采用分流制,新区建设采用严格的雨污分流制,现建成区范围对管网系统进行全面整治,逐步改造成严格的分流制,平顶山市第二污水处理工程近期建设规模为5万m3/d,远期建设规模为15万m3/d。根据平顶山市相关规定和环境保护要求,处理后的水厂出水水质要求达到《城镇污水处理厂污染物排放标准》中一级A标准,采用氧化沟为主体的污水处理工艺。
[Abstract]:At present, the drainage system of Pingdingshan city is divided into two parts, namely, the first sewage treatment plant and the first sewage pump station. According to the overall development plan and adjustment of drainage system in Pingdingshan, the second sewage treatment plant should be built. The short-term project is 2012 and the long-term project is 2020. The service scope of the project is south of Shenma Avenue and Zhan Nan Road, east of Guangming Road, north of South third Ring Road and west of Shenma Road, with a service area of about 29.6km2. The second sewage treatment works area is planned as two districts, namely Tiedong District and Tiexi District. Recent service area is about 14.6 km2. Tiedong District is close to the proposed second sewage plant, located in the lower reaches of the Shahe River, and is planned as a high-tech industrial park with light and no pollution. Tiexi from the old urban area near, in the upper reaches of the Shahe River, mainly planning commercial settlements. According to the present situation of drainage engineering in Pingdingshan City, urban sewage volume is predicted to be 400000 tons / day in the near future and 600000 tons / day in the future. The total design scale of the first sewage treatment plant is 250000 tons of sewage per day. The first phase of the project was completed in December 2000, with a daily treatment capacity of 150000 tons, and then discharged into Zhanhe. 100000 tons of sewage treatment was completed and put into operation at the end of 2005. The planning and drainage system adopts a diversion system, and the construction of a new area adopts a strict system of distribution of rain and pollution. Now the scope of the built area comprehensively renovates the pipe network system and gradually transforms it into a strict diversion system. The construction scale of the second sewage treatment project in Pingdingshan is 50, 000 m3 / d in the near future and 150000 m3 / d in the future. According to the relevant regulations and environmental protection requirements of Pingdingshan City, the effluent quality requirement of treated water works reached the first class A standard of the pollutant discharge standard of the municipal wastewater treatment plant, and the wastewater treatment process with oxidation ditch as the main body was adopted.
