浅析用生物淋滤法去除城市污泥中的重金属

Removal of the Heavy Metals from the Urban Sewage Sludge by Using the Bioleaching Process

随着城区污泥量的增加,污泥中重金属造成的二次污染越来越受到人们的重视。在介绍国内外污泥中重金属去除技术发展现状基础上,较为详细地介绍了生物淋滤法去除污泥中重金属机理及影响淋滤效果的因素。

With the increasing of the amount of the urban sludge in sewage treatment plants, more and more attention to the sludge has been paid to heavy metals of the sludge disposal to avoid secondary pollution. This paper introduces the domestic and foreign technologies for removal of the heavy metals from the sewage sludge, and expounds in detail the mechanism of removal of the heavy metals from the sewage sludge by using the bioleaching process and the factors influencing the effect of the bioleaching process.
