- Abstract:
- A comprehensive runoff model of sponge area in a wastewater treatment plant in Shenzhen was established by using InfoWorks ICM hydraulic model software, and the runoff control characteristics of each low impact development (LID) facility were simulated and analyzed. The results showed that the LID facilities had obvious differences in runoff control performance. The combination of LID facilities should be considered as much as possible during LID installation to avoid over-reliance on a single LID facility. Meanwhile, the runoff control effect of each sub-catchment area in sponge area was simulated. According to the simulation results, grassed swales were proposed to construct in No.2 sub-catchment area to improve its runoff control ability. When the runoff pollution was serious, it could be collected directly into the wastewater treatment plant.
