含砷废水处理新进展

含砷废水的传统处理方法，如物理法和化学法的不足之处在于费用高，二次污染大，工程化程度小。生物法在含砷废水处理方面有着广阔的应用前景，并取得了显著进展，特别是生物膜、活性污泥、生物吸附、生物滤池等处理工艺，研究成果已投入工程应用。对近年来含砷废水处理方法的进展进行了综述，并对合砷废水的处理方法进行了展望。

New Progress in the Treatment of Wastewater Containing Arsenic

Physical and chemical methodologies are traditional ways in treating the wastewater containing the arsenic. The high cost, secondary pollution and low engineering level are their disadvantages. Biological methodology has a promising application prospect with a great progress, particularly those treatment processes such as biofilms, activated sludge, bio- absorption, and biofihers. Its research results have been put into engineering practice. A review and outlook of the development of the arsenic wastewater treatment methodologies are presented in this paper.
