摘    要:为解决污泥农用的主要障碍之一——污泥中重金属含量超标的问题,采用生物法对污泥中的重金属沥滤进行了研究.试验结果表明,在土著硫杆菌的作用下,可使污泥中的Cu、Zn、Cd、Cr、Ni、Pb分别有77.7%、80.3%、54.1%、38.5%、71.6%和26.4%溶出;而硫氧化成硫酸可使污泥中的总大肠菌群大量减少.污泥经生物沥滤后,其重金属含量大大低于污泥农用质量标准.

关 键 词:重金属  硫杆菌  生物沥滤  总大肠菌群  污泥

Abstract:In order to solve the problem that high concentration of heavy metals in wastewater sludge limit the application of the sludge on agricultural land, an experiment for metals bioleaching by indigenous sulfur oxidizing bacteria present in sludge was conducted and evaluated. It was found that the heavy metals solubilization results reach 77.7%, 80.3%, 54.1%, 38.5%, 71.6% and 26.4% for Cu, Zn, Cd, Cr, Ni and Pb respectively, and the sulfate, as a result of sulfur oxidation by indigenous thiobacilli of sludge, allows a considerable reduction in the total coliforms.
Keywords:heavy metals  thiobacilli  bioleaching  total coliforms  sewage sludge
