- 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.
