水中重金属污染处理方法研究

Study on Treatment of Heavy Metal Pollution in Water

水中重金属污染对环境的危害极大,如何去除水中有毒重金属是一个重要的研究课题。综述了目前常见的重金属处理方法,包括化学沉淀法、氧化还原法、电解法、渗透膜法、理化吸附法等传统处理方法,以及生物吸附法、生物表面活性剂修复、硫酸盐还原菌去除法、纳米材料与微生物复合材料等生物处理方法。相比传统处理方法,生物法具有处理效率高、无二次污染、来源广、成本低、环境友好、易于原位修复等优点,具有广阔的应用前景。

The heavy metal pollution in water will cause serious damage to the environment,so how to remove the toxic heavy metals in the water is an important research topic. The common methods of heavy metal treatment were summarized,including chemical precipitation,oxidation reduction,electrolysis,osmotic membrane,adsorption and other traditional treatment methods,as well as biological adsorption,biological surface active agent,sulfate reducing bacteria to divide,nano materials and microbial composite materials and other biological treatment methods. Compared with the traditional processing method,biological method has the advantages of high efficiency,no secondary pollution,wide sources,low cost,environmental friendliness,easy in-situ repair and so on,which has broad application prospect.
