| 摘 要： | 以北京市大兴区庞各庄镇污水处理厂的堆肥污泥、生污泥和通州区的熟土为对象,探讨污泥混配土淋溶液中相关指标的动态变化.结果表明,生污泥、堆肥污泥和熟土混配后可降低土壤pH值,增加土壤全氮、全磷含量,同时也增加了土壤中重金属As、Cd、Ni、Cu、Ph的含量,生污泥系列淋滤液中Pb对地下水造成污染的可能性最大;堆肥污泥系列淋滤液中给地下水带来污染可能性最大的因子是As.但各处理中重金属的污染程度都很低,基本符合国家第II类地下水水质标准,因此淋滤液中的重金属基本不会对地下水造成污染.

| Abstract: | Taking Panggezhuang town,Daxing district sewage treatment plant's composting sludge,raw sludge,and Tongzhou local mellow soil as an example,This paper explores the dynamic changes of the sludge mixed soil leachate index.The results show that,the pH of mixed soil was reduced,and the soil total nitrogen,total phosphorus content of mixed soil were increased,also increased soil heavy metals As,Cd,Ni,Cu,Pb content,the heavy matal Pb in raw sludge series leachate maybe takes the most important part in polluting t... |
