An Approach to the Assessment of Environmental Pollution Caused by House Refuse
生活垃圾对环境的污染评价方法探讨

Environmental pollution caused by house refuse mainly finds expression in the pollution of garbage leachate to surface water, ground-water and soil. The pollution assessment involves the determination of pollutant indexes and pollutant standard values as well as the formulation of calculation modulus. According to previous similar assessment and currently-used assessment method for house refuse pollution, the pollution monitoring items for surface water, groundwater and soil determined in The Environmental Monitoring Standard for the House Refuse Landfill (CJJ/T3037-95) have already been put forward. On such a basis, the authors classify the indexes of these pollution items into five classes, i.e. , Class I, extremely toxic pollution index; Class II, highly toxic pollution index; Class III, moderately toxic pollution index; Class IV, lowly toxic or slightly toxic pollution index; and Class V, common (or non-toxic) pollution index. Through a further comparison, the maximum value is sorted out as the comprehensive pollution index of the total pollutants. An analysis of the case study shows that the suitability of this technique for the data distribution of various pollutants is better than other commonly-used methods.
