摘　　要：文章对完全直排式合流排水体制、截流式合流排水体制、完全分流排水体制、截流式分流排水体制四种排水体制进行对比分析,实际工程中应经方案对比确定适合旧城区排水系统改造的体制;同时对雨污分流设计中的设计要素进行了研究,雨水系统与污水系统的设计参数不尽相同,需要分别研究。此外,文章还对旧城区排水系统雨污分流改造过程中可能遇到的管线接入问题、地下水问题及养护问题进行了研究,并提出了相应的解决方法。This paper makes a comparative analysis of four drainage systems of fully direct combined drainage system,intercepting combined drainage system,fully separate drainage system and intercepting separate drainage system.In the actual project,the system suitable for the reconstruction of the drainage system in the old urban area should be determined through scheme comparison.At the same time,the design elements in the design of rainwater and sewage diversion are studied.The design parameters of rainwater system and sewage system are different,which need to be studied separately.In addition,this paper also studies the problems of pipeline access,groundwater and maintenance that may be encountered in the rainwater and sewage diversion reconstruction of the old urban drainage system,and puts forward the corresponding solutions.
