摘要
龙潭西湖位于北京市中心城区,承接上游地区雨污合流暗沟排水。大雨时,暗沟中的合流制溢流排入龙潭西湖,造成湖水环境恶化。为了有效缓解龙潭西湖合流制溢流污染,综合考虑水环境和水安全的治理目标,在龙潭西湖湖底设置有效容积为62000 m^(3)的调蓄系统截流合流制溢流,采用硅砂蜂巢过滤净化创新技术实现对合流制溢流过滤、净化后再排放。项目实施后,汛期年均溢流次数不大于4次,缓解了龙潭西湖合流制溢流污染,非汛期实现了湖水循环净化。
Longtanxi Lake,located in the downtown area of Beijing,undertakes the drainage of rainwater and sewage in the upper reaches through underground ditches.During heavy rain,the combined overflow water in the underground ditches is discharged into Longtanxi Lake,resulting in a deterioration of the lake’s aquatic environment.In order to effectively alleviate the pollution caused by the combined sewer overflow in Longtanxi Lake and comprehensively consider the governance goals of water environment and water safety,the project addresses this issue by installing an innovative regulation and storage system at the bottom of the lake with an effective volume of 62000 m^(3) to capture and detain the combined overflow.The regulation and storage tank system adopts silica sand honeycomb structure,which is convenient for the combined overflow to be filtered and purified before being discharged.After the project is implemented,the average annual overflow frequency shall not exceed 4 times in flood season,which can effectively alleviate the pollution caused by the combined overflow.During non‑flood season,the system enables the lake water to be circulated and purified.
