宁波市铜盆浦垃圾填埋场对周边水环境影响分析

Quality Evaluation of the Water Around the Ningbo TongponpuMunicipal Waste Landfill Site

为探讨铜盆浦垃圾填埋场对周围水体的污染特征，对近年来该区域附近的水质监测结果进行分析研究及P值评价，结果表明，该垃圾填埋场对周围水体的污染主体上为中度污染，填埋场内部的Ⅲ区水域为重污染。主要污染物为CODcr、BOD5、NO2-N、D0等有机质类指标，重金属含量很低。各监测站位在不同水期污染程度不同，一般丰水期的水质差于枯水期。

For studying the water contamination characteristics around the Tongponpu municipal waste landfill site,the water quality monitoring results in the lastly six years is analysed, and the evaluation is carried out using the integrated pollutde index （P value） .The results show that water quality of the Tongponpu area was mainly middle polluted in 2001,few was seriously polluted. The evaluation also showes that some are the mainly indicators to affect the water quahty：CODcr,BODs,NO2 -N,DO.The degrees of pollution in different times were different.
