随着工农业的发展，水体遭受硒污染的情况越来越严重，水体中硒超标的现象也日趋普遍。含硒工业废水主要来源于生产硒和应用硒的行业，如冶炼含硒金属矿石、炼油、火力发电、制造硫酸、颜料及特种玻璃等行业。对炼厂污水水质进行详细的硒含量分析，并对炼厂污水进行混凝实验及活性炭吸附实验，为含硒废水的处理提供参考。实验结果表明，只采用三氯化铁溶液作为混凝剂的混凝实验对硒等污染物的去除效果较好，硒的去除率在活性炭吸附实验中的去除效果相对较差，粉末活性炭、煤质颗粒活性炭、柱状活性炭中，柱状活性炭的去除效果较好。

With the development of industry and agriculture, selenium pollution has become more and more serious. The phenomenon that selenium content exceeds the standard is also becoming increasingly common. Selenium containing wastewater comes mainly from the production and application in selenium industry, such as smelting selenium metal ore, oil refining, power generation, and production of sulfuric acid, pigment and special glass industry. In the research, selenium content in refinery waste water was analyzed, and coagulation experiment and activated carbon adsorption experiment of the refinery sewage were carried out. The experimental results indicate that, the coagulation experiment with ferric chloride as coagulant has removal effect for selenium, but removal effect of activated carbon adsorption for selenium is relatively poor, and removal effect of columnar activated carbon is better than powdered activated carbon and coal granular activated carbon.
