生物淋滤法对污水污泥中重金属去除效果研究
Removal of Heavy Metals in Urban Sewage Sludg by Bioleaching
摘要
Abstract
Chemical forms of heavy metals from concentrated sludge from certain sewage treatment plants in Taiyuan were analyzed by Sequential Extraction Technique. All the heavy metals measured did not exceed the standard of alkalescent soil; only the content of Zn and Cu exceeded the standard of acidic soil. The unsteady chemical forms of element Zn took a high percentage in sludge, other metals were more steady. On the basis of the results, influence on removal effect with different inoculum sizes and sulfur concentration by bioleaching was investigated. The results show that efficiency was optimum with inoculum sizes of 3 % and sulfur concentration of 3 g/L.关键词
