摘要:城市排水系統(tǒng)旱季階段性冒溢對生活污水污染物的收集處理和排水系統(tǒng)的安全穩(wěn)定運行造成了不利影響。從污水收集管道長期高水位運行對管網(wǎng)調(diào)蓄能力的影響，城市河湖水、地下水、山泉山溪水、工業(yè)企業(yè)廢水、施工降水、商業(yè)娛樂活動排水等非生活污水排入擠占管網(wǎng)空間和瞬時排入形成的沖擊影響等方面，探討了城市排水系統(tǒng)旱季階段性冒溢的成因。在此基礎(chǔ)上提出逐步降低污水收集管道的運行水位、將非生活污水溯源清退作為重點工作方向，以及進一步強化排水戶監(jiān)管和管網(wǎng)日常維護管理等工程和管理對策建議。
Abstract:The periodic overflow in dry season has negative impact on the centralized collection and treatment of urban domestic sewage. It is also unfavorable to the safety and operation stability of the drainage system. This paper discusses the causes of periodic overflow of urban drainage system in dry season including the following two aspects： Ⅰ) reduced storage capacity of the pipe network due to the long-term operation of sewage collection pipes with high liquid level, Ⅱ) non-domestic sewage discharge into the pipe network space, such as urban river and lake water, groundwater, mountain springs and streams, industrial enterprise wastewater, construction dewatering, commercial and recreational drainage, etc. On this basis, some engineering and management countermeasures and suggestions are put forward, such as gradually reducing the liquid level of sewage collection pipelines, focusing on the tracing to the source and removal of non-domestic sewage, strengthening supervision of drainage households and daily maintenance and management of pipe network.
