- 摘要:
- 采用InfoWorks ICM水力模型软件构建了深圳市某水质净化厂的海绵体模型，模拟分析了各低影响开发（LID）设施的径流控制特性。结果表明，各LID设施具有明显的径流调控性能差异，在进行LID设施布设时应尽量考虑LID设施的组合，避免过度依赖单一LID设施。另外，对海绵体各排水分区的径流控制效果进行了模拟，根据模拟结果，建议对2号排水分区增设植草沟以提高其径流控制能力，当径流污染较严重时，可直接收集后排入水质净化厂进行处理。
- 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.
