智能分流井在流域治理中的设计应用及思考

Design and Application of Intelligent Diverting Well in Watershed Management

以湛江某流域治理排污口截流井选型为例,研究智能分流井在流域治理中的技术优势及应用场景。通过下开式堰门智能分流井在主要排污口的应用,证实智能分流井在防止河水倒灌及溢流污染控制方面的巨大优势,智能分流井能够有效改善河道水质,提高水环境的治理效果,为其他水环境治理项目提供借鉴。同时,提出沿河排污口截流改造是流域水环境治理第一步,要实现长制久清,应进一步考虑合流制溢流CSOs污染控制、合流暗渠清污分流、排水单元源头精准截污及雨污分流改造等建议。

Taking the selection of sewage interception well in a watershed in Zhanjiang as an example,the technical advantages and ap‐plication scenarios of intelligent diversion well in watershed governance are studied.Through the application of the down weir gate intelligent diverting well in the main sewage outlet,it is proved that the intelligent diverting well has great advantages in the control of river water backflow and overflow pollution control.The intelligent diverting well can effectively improve the water quality of the river and improve the treatment effect of the water environment,and provide reference for other water environment treatment projects.At the same time,it is put forward that the interception and improvement of drainage outlets along the river is the first step of environmental governance in the basin.In order to achieve long-term control and long-term cleaning,some suggestions should be further considered,such as CSOs pollution control of combined overflow system,pollution diversion of combined culvert,accurate interception of drainage units at the source and rain and pol‐lution diversion transformation.
