摘　　要：鉴于历史原因,许多城镇旧城排水系统大部分采用完全合流制,城镇道路普遍狭窄,无法实现完全分流制的改造,因此,城镇污水管网改造项目可考虑采用截流式合流制的排水体制,那坡县污水处理厂一期配套管网工程沿涝水河、城厢河河床两侧布置截流式合流制排水干管,从投资、拆迁、施工、管理等方面进行方案对比和优化设计,最终提出一个较优的方案。Due to historical reasons, the combined system has been adopted in most old sewage systems in many cities and towns. Because the urban roads are narrow, the reconstruction of separate system cannot be achieved. Therefore, the interception combined system could be adopted in reconstruction of urban sewage pipe network. The interception combined sewer system was planned to be arranged on the both sides of the riverbeds of Laoshui River and Chengxiang River in the auxiliary pipe network project in first＂ phase of Sewage Treatment Plant in Napo County. The scheme comparison and optimization design were conducted in terms of investment, removal, construction, management and so on. A better design scheme was proposed.
