摘要
我国矿产资源丰富,有色金属矿中均含有有害金属铊。近年来铊中毒事件频发,水体污染严重,对人们的生产和生活造成了严重影响。为保护生态环境,国家和地方政府制定了更加严格的控制标准。对含铊废水的治理提出了更高要求。根据国内外铊治理技术现状和研究进展,综述了近年来国内外常用的铊治理方法和工艺特点,对硫化沉淀法、吸附法、离子交换法、生物制剂法、电化学法等方法的优缺点进行分析。在处理含铊工业废水时,不应当只进行单个工艺操作,应当综合各种工艺优点,组合工艺将会时未来的发展重点。
China is rich in mineral resources,and all nonferrous metals contain thallium metal in non-ferrous mines.In recent years,thallium poisoning was frequent and water pollution was serious,which seriously affected people's production and life.In order to protect the ecological environment,the state and local governments have formulated more stringent control standards.Higher requirements were put forward for the treatment of wastewater containing thallium.According to the present situation and research progress of thallium treatment technology at home and abroad,the characteristics of thallium treatment methods and processes commonly used at home and abroad in recent years were summarized,and the advantages and disadvantages of sulfide precipitation,adsorption,ion exchange,biological preparation and electrochemical methods were analyzed.When treating thallium-containing industrial wastewater,we should not only carry out a single process operation,but also integrate the advantages of various processes,and the combined process will be the focus of future development.
