摘　　要：通过对昆明东郊垃圾填埋场渗滤水水样进行采集分析,探讨了垃圾渗滤水水质污染现状及其污染特性。结果表明,渗滤水原液及经初步处理后水池水质电导率、溶解氧量、化学需氧量、氨氮量、全磷量、氟离子、氯离子均超标(Ⅴ类)严重;pH值、浊度与叶绿素3项指标有不同程度偏高。垃圾渗滤水含盐量高、还原性物质多、水质表观差。渗滤水经最终处理后有多项水质指标得到明显改善,但有些指标(如氟离子、氯离子、氨氮量)仍然较高,未达到地表水Ⅴ类标准。经综合评价分析,垃圾渗滤水原液、经初步处理后的渗滤水及最终处理后的渗滤水,其水质综合污染指数均远大于3.0,属重度污染水平,而当地水库的水质在清洁水平范畴,未受垃圾渗滤水污染。In this paper, based on sampling and analyzing the percolating water of Eastern Suburbs Refuse iandfill Site in Kunming, the present situation and pollution characteristics of the refuse percolating water quality were discussed. The results showed that the conductivity, DO, CODcr, NH3 - N, TP - P, F-, C1 - of the raw and preliminary disposed per- colating water greatly exceeded the standards （GradeV）. The pH value, turbidity and chlorophyll were higher than their normal values to different degrees. The salt content of the percolating water was higher, the reductive material was in large amount and the water had a poor appearance. After the treatment, several water quality indexes were improved. But some （F-, C1-, NH3 -N） were still higher, worse than the Grade V standards. The results of the comprehensive evaluation and analysis of the raw water, the preliminary treated and the finally treated percolating water showed that their pollution index was far more than 3.0. In other words, they were heavily polluted. However, the water quality of the local reservoir was still clean, without being polluted by the landfill percolating water.
