Agriforest Disposal and Utilization of Sludge

污泥的农林处置与利用 ,要解决三个主要问题 :①污泥中重金属能否造成土壤及作物的二次污染 ;②污泥中病原体能否对环境造成影响 ;③氮磷等物质浓度过高能否对地下水造成污染 ,针对这三个问题 ,进行国内外研究工作综述。

Three problems should be settled in agriforest disposal and utilization of sludge:whether the heavy metals in the sludge will lead to the secondary pollution in soils and crops,whether the pathogen will exert influence on the environment and whether the highly-concentrated Nitrogen and Phosphate will result in Pollution in the underwater.The study of these problems at home and abroad is summarized in the article.
