摘　　要：研究铁硒共沉淀方法除硒影响因素,探讨含硒原水处理的工程设计参数和运行控制条件。研究结果表明,FeCl3作为沉淀剂适宜投加量为5mg/L,搅拌时间在5-10min为宜,最佳pH在6-8;而且适宜的原水浊度和水温范围较大。The affecting factors on Fe-Se co-precipitation system for Se removal from raw water were studied to find out the necessary design and operating parameters. The research results shown that best removal will be obtained at condition like this: dosage of precipitation agent FeCl3 5 mg/L, pH of the solvent 6-8 and mixing time 5 - 10 min. At this condition, the suitable range of turbidity and temperature of raw water were wide.
