【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,并对含砷废水的处理方法进行了展望。更多还原

【Abstract】 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 biofilters.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.更多还原
