摘　　要：针对不同高砷地下水污染问题,为探索有效的治理措施,介绍了我国地下水砷污染现状,阐明了地下水中砷的释放机理,综述了当前高砷地下水常用处理工艺,并对各处理工艺特点进行了详细归纳和总结。研究表明:混凝沉淀法和吸附法因其工艺简单,成本较低,应用范围较广;离子交换法和膜分离法去除率高,但因运行费用高,工艺复杂,应用较少;生物处理法具有工艺简单,成本低,无二次污染等特点,在高砷地下水修复领域具有较好的应用前景,有待进一步深入研究,并有可能发展成为未来治理地下水砷污染的有效方法。In order to explore effective treatment measures for different groundwater pollution problems with high arsenic content, the present situation of arsenic pollution in groundwater in China was introduced, the releasing mechanism of arsenic in groundwater was elucidated, and the common treatment technology for treating high arsenic in groundwater was reviewed. The characteristics of each treatment process mentioned above were concluded and summarized in detail. The study showed that coagulation sedimentation method and adsorption method are widely used because of their simple process and low cost. Ion exchange method and membrane separation method have high removal rate, but they were rarely used because of high operation cost and complex process. The biological treatment has a good application prospect in the field of arsenic groundwater remediation due to its simple process, low cost and no secondary pollution. The biological treatment needs to be further studied and may be developed into an effective method to treat groundwater arsenic pollution in the future.
