- Abstract:
- Shahe Reservoir in Beijing has been faced with problems such as the afflux of multiple source pollution, fragile ecosystems, and lack of hydrodynamic force, representing the characteristics of a slow stagnant water body replenished with reclaimed water. The demonstration project which mainly include overflow pollution prevention and control, non-point source pollution reduction, and reservoir ecological restoration was adopted in order to solve the above problems. Treatment measures include reservoir-side vegetation buffer zone, initial rain interception and overflow pollution control of the combined drainage system, ecological restoration of wetland, etc. Before the implementation of the project, it is necessary to predict indicators such as incoming pollution volume, water environment capacity, and pollution reduction loads of engineering measures, then analyze the target accessibility and correct design parameters. After the implementation of the project phase, the external source pollution of Shahe Reservoir has been controlled, and the water environment quality has been significantly improved. The systematic scheme is effective in Shahe Reservoir treatment and can provide practical reference for similar reservoir and lake water environment treatment projects.
