焦点提醒：我国城市排水系统近况、问题与成长建议 作者:邢玉坤1, 曹秀芹1, 柳婷1, 徐国庆1, 杨超2, 卢长松2, 何嘉伟2 要害词:font-size: 10pt; ">管网问题; 排水系统; 污水处置举措措施; 水情况管理; 污水排放量
跟着城市化、工业化速度的加速，我国城市污水排放量逐年增加，污水处置举措措施范围逐年增年夜，但城市水情况管理仍然具有问题。经由过程阐发2002年—2016年我国城市污水处置举措措施的成长与近况，发觉我国污水处置举措措施的根本扶植已根基完成，污水排放量与结尾处置举措措施能力的矛盾已获得减缓且污水处置举措措施留不足量，污水处置举措措施的扶植由阶梯式的快速增加模式改变为跟着城市生齿转变与城市扶植而转变的可延续成长模式。而城市水情况污染管理的首要标的目的已改变为处理管网问题与水情况管理近况之间的矛盾，管网范围不足、混接问题严峻、地下水入渗、合流制溢流、调蓄扶植不足是将来排水系统应当处理的首要问题。

With the acceleration of urbanization and industrialization,the discharge of municipal wastewater and the scale of wastewater treatment facilities in Chinahave been increasing year by year.However, there are still problems in urban water environment management. By analyzing the development and current situation of municipal wastewater treatment facilities in China from 2002 to 2016, the infrastructureof wastewater treatment facilities have been basically completed, the contradiction between the endtreatmentinfrastructure capacity and wastewater dischangehas been alleviated, and the wastewater treatment facilities have left the remaining treatment capacity, so the construction of wastewater treatment facilities has changed from a stepped rapid growth model to a sustainable development model dominated by urban population change and urban construction. At the present stage, the main direction of urban water environmental pollutiontreatment has been transformed into solving the contradiction between the problems of pipe networkand the current situation of water environment treatment. Insufficient length of pipe network, serious problem of misconnection of pipe network, infiltration of groundwater in pipe network, overflow of combined flow and construction of storage facilities are the main problems, which should be solved in future drainage system.
