生物淋滤技术在污泥重金属处理中的效果研究进展及对比分析

摘要

文章阐述了生物淋滤法在去除污泥重金属中的机理、影响因素以及处理效果．并与植物提取、电动修复、化学法去除污泥重金属等方法的应用进行了对比。生物淋滤法去除污泥重金属表现出了较好的应用前景，未来从污泥中筛选淋滤菌种，开展生物淋滤工艺研究和配套设备开发将成为生物淋滤技术规模化应用的研究重点。%In the paper, a review of bioleaching in removing heavy metals from sewage sludge was presented in mechanism, influencing factors and treatment effect, and comparisons of the application was made among the methods of phytoextraction, electro reclamation, and chemistry. There shows a better application prospect for the method of bioleaching in removing heavy metals from sewage sludge. The study about the screening of leaching strains from sludge, process of bioleaching, exploitation of matching equipments would becoming the research priorities about the large-scale application of bioleaching in the further.
