摘要
通过林地处理城市污水污泥实验，结合硝态氮不易被土壤吸附及易溶性，研究了硝态氮在土壤中的迁移及对地下水的影响。确定了天津地区污泥的施用时间以３月份最佳，严格控制污泥负荷量不超过７５ｔ／ｈｍ２．ａ。为污泥资源化提供了依据。
Nitrate movement in soil and its effect on groundwater were studied by using expriement on forest land where sewage sludge had been utilized.The results showed that suitable application time for agricultural use of sludge in Tianjin was in march with the highest loading rate of 75 t/hm 2·a.
