医院水污染源排放量估算及污染源评价

采用产排污系数法对某区域4家综合医院水污染物的产排污情况进行了估算与分析,分别采用等标污染负荷法和单位产值等标污染负荷法对研究区域4家医院水污染源进行评价,指出该区域医院行业的主要污染源及主要污染物.结果表明,单位产值等标污染负荷法剔除了行业规模对污染负荷的影响,在一定程度上反映了污染源对环境和经济的综合影响,但该法仅适用于工业污染源和赢利性质的生活污染源评价,而不适用于非赢利单位污染源的评价.

Estimation of Discharge from Water Pollution Source of Hospital and Pollution Source Assessment

The production and discharge of pollutants from four hospitals were estimated via the coefficients of production-discharge pollutant. Water pollution sources of these four hospitals were assessed by equal standard pollution load method and unit product equal standard pollution load method. The main pollution sources and main pollutants of hospital in studied area were pointed out according to the calculated results. The results indicated that unit product equal standard pollution load method could reflect the combined influence of pollution source on the environment and economic,which picked out the effect of industry scale for pollution load,but it is unsuitable to assess the pollution source of non-profit unit.
