土滤法处理生活污水对土壤理化性质的影响

[目的]为土滤法处理生活污水的深入研究提供参考。[方法]分别检测土滤法生活污水处理区及未处理区(CK)土壤的7个理化指标,探讨土滤法处理生活污水对土壤理化性质的影响。[结果]土滤法生活污水处理区的土壤容重有所增大,土壤孔隙度减小,全氮、速效磷、速效钾的含量均显著高于CK,有机质含量有所提高,土壤pH值平均为5.24,CK土壤pH值为5.30。土滤法生活污水处理区植物生长良好,无病害出现。[结论]土滤法处理生活污水对提高土壤肥力有一定的促进作用,对土壤养分的存在状态和转化无明显影响。

Effects of Treating Domestic Sewage by Soil-filtering on the Physical and Chemical Properties of Soil

[Objective] The study aimed to provide references for the deep research on treating domestic sewage by soil-filtering.[Method] Seven physical and chemical indices of soil in treated area and non-treated area(CK) of domestic sewage by soil-filtering were detected resp.The effects of treating domestic sewage by soil-filtering on the physical and chemical properties of soil were discussed.[Result] In the treated area of domestic sewage by soil-filtering,the soil volume weight had some increase,the soil porosity reduced,the contents of total nitrogen,available phosphorous and potassium were significantly higher than that in CK,the content of organic matter had some enhancement,the average pH value in soil was 5.24 and that in CK was 5.30,the plant grew well and there was no disease occurred.[Conclusion] Treating domestic sewage by soil-filtering had some promoting effects on enhancing soil fertility and had no significant effect on the existing state and transformation of soil nutrients.
