摘　　要：含水介质对垃圾污染质的自然净化能力受多项因素影响,是一个相当复杂的综合过程。本文选定生活垃圾淋滤液中对地下水有影响的主要污染物TP、COD、TN、NH3-N和细菌为试验污染组分,天津地区常见的中砂、粉砂和粉土为试验土样,通过室内模拟试验,利用表征指标—截留量和净化率,探讨砂性含水介质对垃圾污染质的自然净化能力。试验结果表明,指标值越大,含水介质对污染组分的自然净化能力越强;不同砂性含水介质对不同垃圾污染质的自然净化能力没有一致性规律。因此,在探讨含水介质对垃圾污染质的自然净化能力时,既要考虑含水介质的不同,也要分析污染质中不同污染组分含量的大小。The natural purification abilities of sandy water-bearing media to garbage pollutants are influenced hy many factors, which are a rather complicated process. Taking the main pouutants such as the TP, COD, TN, NH3 - N and bacteria as the test pollution compositions, and taking the medium sand, the silty sand and the silt in Tanjin as the test soil samples, though the laboratory simulation test, the purification abilities of sandy water-bearing media to garbage pollutants; the natural purification abilities have unconformity rules for different sandy water-bearing media to different garbage pollutants. So when the natural purification abilities of sandy water-bearing media to garbag difference of water-bearing media should be considered and the contents of e pollutants are discassed the pollution compositions, should also be analyzed.
