摘要:
水质调蓄池削减城市径流污染的作用已被广泛关注，其设计及运行规则是优化控制效果的关键。为此，采用InfoWorks ICM排水模型建立区域概化水文模型、模拟径流污染特征，并重点设计了调蓄池运行规则。研究发现，采用时间、径流污染物浓度两种调蓄规则均优于传统遇雨则开的方式。基于时间运行规则时，单位池容污染负荷控制率呈现先上升再下降的趋势，最优参数是降雨后20 min开启调蓄；基于污染物浓度运行规则，调蓄池体积为5 800 m3时采用COD浓度控制，调蓄池体积为5 000 m3时采用TP浓度控制，均在池容未100%利用时达到了较好的污染物控制效果。最后，基于污染物变化特征和区域用地限制提出了适宜的调蓄池运行规则，可为调蓄池运行规则设计提供新思路，并为水质调蓄池智能运行提供技术支撑。
Abstract:
The effect of water quality storage tank on urban runoff pollution control has been widely concerned, and its design and operation rules are the key to optimize the control performance. In this paper, InfoWorks ICM drainage model was used to establish a regional generalized hydrological model, simulate the characteristics of runoff pollution, and design the operation rules of the storage tank. The two regulation rules based on time and runoff pollutants concentration were superior to the traditional opening mode in case of rainfall. When the operation rule based on time was employed, the pollution load control rate per unit tank volume increased first and then decreased, and the optimal start-up time was 20 min after rainfall. Based on the pollutants concentration operation rule, COD concentration control was adopted when the storage tank volume was 5 800 m3, and TP concentration control was employed when the storage tank volume was 5 000 m3, both of which achieved good pollutants control performance when the tank volume was not 100% utilized. The appropriate operation rules of the storage tank were proposed based on the characteristics of pollutants change and the restriction of regional land use, which provided a new idea for the design of the operation rules and technical support for the intelligent operation of the water quality storage tank.
