摘要/Abstract

摘要： 科学合理地处置城市污泥业已成为中国当前亟待解决的重要环境问题.剩余污泥土地利用是一种最具发展潜力的处置方式,但是污泥中含有多种重金属、有机污染物、养分元素等,土地利用后能否产生淋溶风险,是否对土壤、地下水甚至人体健康产生危害存在较大争议.为此,本文对污泥土地利用后重金属、有机污染物以及养分的淋溶风险进行了论述,并对污泥土地利用的未来发展方向进行了展望.

关键词: 城市污泥, 淋溶, 土地利用, 环境风险

Abstract: In our country,dealing with sewage sludge scientifically and reasonably has become an important and urgent environmental problem.Land application of urban sewage sludge is the most promising way of the disposal.However,sludge contains a variety of heavy metals,organic contaminants and nutrients.It remains unclear whether these pollutants in the sludge may leach into soil and groundwater,and cause harm to human health.In this paper,the risk of heavy metals,organic contaminants and nutrients after the sludge land use were reviewed.The problems in the future development about land application of urban sewage sludge were pointed out.

Key words: urban sludge, leaching, land application, environmental risk
