摘要
为达到深圳市水环境长治久清及可持续发展总体要求,结合龙岗河流域水环境治理工程提出“封闭的污水系统、开放的雨水系统以及高效的截流系统”为一体的三水分离总体方案。以重点排口溯源分流、截污点改造为手段,实现清洁基流释放、污水系统同初小雨系统相对独立,达到面源污染减缓、污水处理厂提质增效、管网系统运维调度强化的目的。随着三水分离工程实施,2020年下半年之后龙岗河流域污水处理厂进水BOD浓度较2019年有显著提升。因此,实现深圳市治水提质考核要求及建设任务,水环境治理中应用三水分离工程十分必要。
To fulfill the overall requirement of long-term cleanliness and sustainable development of the water environment in Shenzhen, this paper investigates the Longgang River Basin Water Environment Management Project to propose a general three-water separation plan that integrates “closed sewage system, open rainwater system, and efficient interception system”.Tracing to the source and diversion of key outlets and sewage interception transformation are carried out to release the clean base flow, drive the sewage system to be relatively independent from the initial light rain system, and ultimately to slow down non-point source pollution, improve the quality and efficiency of the sewage treatment plant, and strengthen the operation and maintenance scheduling of the pipe network system.With the implementation of the three-water separation project, the influent biochemical oxygen demand(BOD) concentration of the sewage treatment plant in the Longgang River Basin is significantly lower than that in 2019 after the second half of 2020.Therefore, applying the three-water separation project to water environment treatment is essential for fulfilling the assessment requirements on water control and quality improvement in Shenzhen and accomplishing relevant construction tasks.
