新时期城市环境工程改造模式更加优化,尤其在给排水工程建设方面提出新思想。作为现代给排水系统的一种改造方式,“集中式”给排水系统结构更加合理化,所承载的污水处理效能更高。结合集中式给排水现状,总结了对环境除污的治理作用,提出切实可行的集中式给排水系统方案。 In the new era, the urban environmental engineering mode is more optimized, especially in water supply and drainage engineering. As a modification of modern water supply and drainage system, the structure of “centralized” water supply and drainage system is more rationalized and the sewage treatment carried by it is more efficient. Combined with the status of centralized water supply and drainage, summing up the role of environmental decontamination governance, put forward a practical program of centralized drainage system.
