摘　　要：重金属是目前污泥土地利用的最大障碍,有效去除污泥中的重金属成为污泥再次利用的关键。微生物淋滤法作为一种高效、低成本、绿色的污泥重金属的处理方法,展现出广阔的应用前景。综述了污泥重金属去除技术的优缺点,分析了微生物淋滤技术的优越性及去除效果,展望了微生物淋滤技术的前景与方向。Heavy metals is the biggest obstacle to sludge land utilization, to effectively remove heavy metals from sludge has become the key point of sludge reutilization. Bioleaching, as an efficient, low-cost, and green method for sludge heavy metals processing, has showing its broad application prospect. Through an overview of the advantages and disadvantages of heavy metals removal technology, the superiority of bioleaching technology and its performance for heavy metals removing were analyzed, the foreground and development direction of bi- oleaching technology were prospected.
