摘　　要：电镀污泥含铜、镍、锌等重金属,属于危险废物,必须进行无害化处理。同时,电镀污泥含的重金属又是不可多得的资源,具有资源回收价值。微生物淋滤技术具有反应温和、产生二次污染物少等优点,与酸浸出相比具有优势。本文介绍了生物淋滤技术在电镀污泥资源回收有价金属方面的应用,并提出了发展趋势。Electroplating sludges contain various heavy metals such as copper, nickel and zinc which are hazardous wastes, must be treated innocuously.However, the heavy metals in electroplating sludge are also rare resources, which are worth recycling. Compared with acid leaching, bioleaching technology has the advantages of mild reaction and less secondary pollutants. This paper introduced the application of bioleaching technology in the valuable metals recycling from electroplating sludge, and put forward the developing trends.
