摘　　要：受微量硒污染的原水处理目前尚无现成的处理工艺或方法套用 ,为此考察了铁硒共沉淀法的除硒效果。结果表明 ,当原水硒浓度为 5 0 μg/L、FeCl3投量为 5～ 80mg/L时 ,对硒的去除率为 83.84 %～ 98.39% ,出水硒浓度为 0 .818.0 8μg/L ,完全满足生活饮用水水质标准中对硒含量的规定。研究中还发现 ,FeCl3的除硒效果比FeSO4 好。As it stand,there is no mature process to be used to treat the raw water polluted with micro-level selenium.For this reason,the process of Fe/Se co-precipitation was studied on its selenium removal efficiency.Result shows that selenium removal efficiency can reach 83.84%-98.39% under selenium concentration of 50 μg/L in influent and FeCl_3 dosage of 5-80 mg/L.After being treated by using Fe/Se co-precipitation process,the outlet water quality with the selenium concentration of 0.81-8.08 μg/L totally meets the drinking water standard for selenium content.In addition,it was found that the effectiveness of selenium removal by FeCl_3 is better than that by FeSO_4.
