含砷废水处理研究进展

Progress of the research on the treatment of As-containing wastewater

含砷废水的传统处理方法如物理法和化学法的不足之处是费用高、二次污染大、工程化程度小。微生物法在含砷废水处理方面的研究取得了显著进展,研究成果已投入工程应用。作者全面介绍了各种微生物方法,着重论述了活性污泥法处理含砷废水的可行性及其主要的影响因素,认为活性污泥法对含砷废水的处理有着广阔的应用前景。

The traditional methods for treating As-containing wastewater, such as physical and chemical ones, have some shortcomings: high cost, serious second pollution, and hard to be applied. Great progress has been made in the research on the treatment of As-containing wastewater with microbiology, and the result has been put into application. In this article, all kind of microbiology methods are introduced. The feasibility and main factor of the treatment of As-containing wastewater with activated sludge are discussed especitally. Wild prospect about the treatment of As-containing wastewater with activated sludge is pointed out.
