摘　　要：就铝硒共沉淀体系除硒影响因素进行研究 ,探讨确定含硒原水处理工程的设计参数和运行控制条件 .结果表明 ,AlCl3投加量在 40mg/L即可 ,搅拌时间在 5～ 1 0min之间为宜 ,最佳pH值则在 6.5～ 7.5之间 。Aimed at finding the design parameter and running data of removal selenium from raw water, studies were made on the effects of the treatment process by using aluminum-selenium co-precipitation system. The findings show that good effect of selenium removal can be achieved when dosage of AlCl 3 is 40 mg/L at pH of 6.5～7.5 with the mixing time of 5～10 min. Moreover, the proper scopes of turbidity and temperature of raw water are wider when this effect is achieved.
