初期雨水调蓄池控制溢流污染研究

Study on Pollution Control of Overflow from Initial Rainwater Storage Tank

利用苏州河沿岸典型排水系统雨天溢流水量、水质变化以及调蓄池处理技术的研究成果,与数学模型研究有机结合,建立了苏州河沿岸排水系统降雨径流水量水质与河网水量水质动态耦合的集成模型,计算分析了在3个典型年实际降雨条件下,苏州河沿岸调蓄池工程对溢流水量、溢流污染物的削减效果,以及控制溢流污染对苏州河水质的改善效果。

Study results on the variation of overflow water quantity and quality from the drainage system in rainy days along the Suzhou Creek and the treatment technology for storage tank were used and combined with the mathematic model to set up the integrative model by dynamically coupling of the rainwater runoff capacity and quality in drainage system with the quantity and quality of water from river net along the Suzhou Creek. Calculation analysis was made for the effect of storage tank on reduction of overflow water quantity and overflow pollutant, and the effect of pollution control of overflow on improvement of water quality in Suzhou Creek under the actual rainfall conditions in three typical years.
