摘要
基于我国排水体制现存特有问题,首次明确了混流排水系统的概念。针对典型混流排水系统——芙蓉江排水系统,对其排江水质污染过程进行研究。结果表明,排江水质污染负荷高、排江水体污染总负荷大,同时在一定降雨条件下存在较明显的排江污染初期效应。在分析导致排江水质较差因素的基础上,对雨水调蓄的污染控制对策进行了分析,得到调蓄池削减污染负荷率最高的调蓄池启动时间点。
Based on the special problems existing in drainage system in China, a new drainage system called disordered drainage system （DDS） was defined. In the light of the representative DDS, namely the Furongjiang drainage system, the pollutants discharge characteristics were studied. The results indicate that the pollution load of water discharged into the river is high, and the total pollution load is high. Under a given rainfall, there is a remarkable first flush effect. Based on the analysis of poor quality of water discharged into the river, control measures of pollutants discharge by storm detention tank are proposed, and the optimal start time of the detention tank is obtained.
