水污染物总量综合权重系数分配方法研究

Distribution of Total Water Pollutants by Comprehensive Weight Coefficients

区域污染物排放总量分配是水污染总量控制的重要内容,分配合理与否将直接影响总量控制工作成效。以陆域排污-水体水质响应空间单元为基础,构建了综合考虑水环境质量、排污及污染治理水平、区域经济实力等因素的总量分配指标体系,提出一套单元的水污染物总量分配综合权重系数计算方法。并将该方法应用于北京市,结果表明本方法较好地解决了目前分配方法中总量目标与水质改善需求衔接不足、分配指标体系过于单一的问题。

How to distribute water pollutants is very important in water pollution total amount control.The distribution is reasonable or not will directly affect the effectiveness of water pollution control.In this paper,a distribution method of total water pollutants was introduced,including structuring land built sewage-water quality response space unit,establishing the multi-index system of total amount distribution based on water quality,sewage and pollution control status,the level of regional economic factors.This method was used in Beijing.The results indicate that it can improve consistency between total amount of water pollutants and water quality,and enrich index system of total amount distribution.
