摘要
污水在处理过程中会产生大量的剩余污泥,其中含有的重金属会造成严重的污染。为了解决剩余污泥污染的问题,本文详述了国内外有关污泥重金属方面的研究原理、特点、现状以及存在的主要问题,并讨论了剩余污泥无害化处理技术的未来发展方向。
A large amount of Excess Sludge is produced in the process of wastewater treatment, which contains lots of heavy metals that might cause serious pollution. In order to solve the problem of excess sludge pollution, this paper summerized the research principle, characteristic, current status and the main problems of heavy metals in sludge both of domestic and abroad, and the developing direction of harmless treatment technology of excess sludge was discussed.
