- Abstract:
- “Clear water replenishment” is an important technical means to comprehensively eliminate black and odorous water bodies in cities. Taking the Maozhou River basin in Shenzhen and Dongguan as the research object, the amount of reclaimed water replenishment was demonstrated by multi-methods. Then reclaimed water replenishment scheme was optimized considering the non-point source pollution after rainfall, which had a significant effect on improving the water quality and water exchange frequency of the river channel, and the water quality could be restored to the standard within 3 days after rain. Taking the reclaimed water replenishment project with a total scale of 150×104 m3/d in Maozhou River basin as an example and adopting the design idea of “water replenishment scale demonstration+pump station pipeline redundancy design + water quality recovery after rain”, a temporal- spatial multi?point dynamic allocation system in the whole basin was constructed, which could provide reference for similar reclaimed water replenishment to rain-source river in high-density built-up areas at home and abroad.
