摘要
本文选用聚合氯化铝做混凝剂,海藻酸钠做助凝剂混凝处理富营养化水体,以总磷、总氮去除率为评价指标,探究海藻酸钠的优化混凝效果及最佳处理条件.结果表明,聚合氯化铝、海藻酸钠的最佳投加量分别为75 mg/L及5 mg/L,投加比例为15:1,pH值为6,快搅时间为90 s,慢搅时间为10 min时混凝效果最好.
Abstract
In this paper,polyaluminum chloride was used as coagulant and sodium alginate was used as coagulant aid to treat eutrophication water.The removal rate of total phosphorus and total nitrogen were used as evaluation index to explore the enhanced coagulant effect and the best treatment conditions of sodium alginate.The results showed that the optimal dosage of polyaluminum chloride and sodium alginate were 75 mg/L and 5 mg/L respectively,the dosage ratio was 15:1,the pH value was 6,the fast stirring time was 90 s,and the slow stirring time was 10 min.
