提高生物法分离制革污泥中铬分离效率的研究
Study on enhancing chromium separation efficiency from tannery sludge by bioleaching
摘要
Abstract
The study on enhancing the heavy metal chromium separation efficiency in tannery sludge by bioleaching, through changing the filters material, the solid separation condition, as well as low pH nutrients and so on was carried out. The chromium separation efficiency of chemical leaching (1: 1 H_2SO_4) under the same condition was investigated. The experiment showed that it could enhance the separation efficiency with the acid liquor(l: 1 H_2SO_4 configuration). In bioleaching when the pH dropped to 1.8, the separation efficiency could achieve 94. 65% .compared to using the distilled water. In chemical leaching when the pH value dropped to 1, the separation efficiency could achieve 96. 7% , the surplus chromium content in the sludge may achieve the standard of making the leather sludge as agriculture fertilizer.关键词
