摘要：

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。

Abstract:

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.

Key words: arsenic, heavy metal, wastewater, microbiology, activated sludge
