上海市苏州河综合整治一期工程正有效、扎实地开展,通过几次调水试验,发现一些问题后,采取了一系列积极有效的措施,为达到苏州河综合整治的阶段目标创造了良好的条件。通过调水试验,发现苏州河市区段的市政泵站,对苏州河防污染的贡献很大。据统计,1996～1999年沿线37座泵站的合流污水排江量如表1所示。 近年来苏州河沿线泵站合流污水排江量 表1 造成合流污水排江量持续较高的原因很多,如沿线泵站设备老化、检修频率高;合流污水治理一期工程总管截流倍数较低、截流管偏小;分流制排
Shanghai Suzhou River Comprehensive Remediation Phase I project is being carried out effectively and steadily, through several water transfer tests and found some problems, adopted a series of positive and effective measures to achieve the goal of Suzhou River comprehensive renovation phase to create a good condition. Through the water transfer test, it was found that the municipal pumping station in the section of Suzhou Creek contributed greatly to the anti-pollution of Suzhou Creek. According to statistics, from 1996 to 1999 along the 37 pumping stations combined discharge of water discharge as shown in Table 1. In recent years, the confluence of pumping stations along the Suzhou Creek along the river drainage meter 1 caused confluence of sewer discharge continued high for many reasons, such as equipment along the aging pump, maintenance frequency is high; confluence of sewage treatment a project of the lower closure of the manifold, Closure tube is small; shunt system
