| 摘 要： | 土地利用是解决城市污泥处理处置的有效途径之一,本文从土壤理化性质、重金属污染风险以及有机污染风险3方面综述城市污泥农用对土壤环境的影响。城市污泥利用为植物提供营养元素,改良土壤结构,提高土壤肥力。污泥施用年限的长短与土壤中重金属的含量高低关系不明显,导致土壤重金属含量增加的主要因素是污泥施用量和污泥中重金属含量。在正常...

| Abstract: | Land application of sewage sludge is one of the effective disposal alternatives.In this paper,the effects of agricultural application of domestic sewage sludge on soil environment were discussed from the respects of physicochemical properties,heavy metals pollution and organic pollution.Sewage sludge application provides nutrients to improve the soil structure and enhance the soil fertility.There was no significant correlation between the length of application lasting time and the heavy metals concentration... |
