摘　　要：按照传统规范设计的排水系统,在实际运行中往往难以达到预期效果。为此提出了改进雨水管出水口和收水口、建设雨水管道之间的连通管、建设住宅小区雨水管道、推广渗水型雨水排水系统等改进意见。对污水系统的改进也提出了户线出口建立格栅井和水质检测井、检查井井底设置沉淀池、检查井内设置闸槽、检查井爬梯安装位置、泵站集水池有效容积和最低水位线确定、集中与分散相结合方式建设污水厂、铺设污水厂进水总管复线等建议。Based on the design idea of traditional specification , the drainage system cannot arrive at the desired results during operation. Several improvement measures are proposed such as improving the outlets and inlets of rainwater pipelines, building connecting pipe between rainwater pipelines, developing the rainwater pipelines in residence community and promoting water leakage drainage system, etc. Moreover, the measures to better the sewage system are also mentioned for instance, building the grid well and water quality monitoring well in the line export, setting a sedimentation tank on the bottom of a manhole and other cautions about the manhole, determining the effective volume and the lowest water line of bumping station collecting tank, building sewage treatment plants with the combination of concentration and decentralization, and paving the complex lines of the inlet general pipeline, etc.
