摘要/Abstract

摘要： 在室温下采用缓慢加入法合成了两种聚合镁铝絮凝剂, 并对实验室废水中化学需氧量(COD)进行脱
除研究。结果表明, 絮凝剂种类、絮凝剂的体积、pH , 处理样品的慢速搅拌时间和沉降时间影响COD 的脱除效果。
聚合硫酸镁铝(PM AS)在pH =8 , 快速搅拌时间为3 min , 慢速搅拌时间为10 min , 沉降时间为30 min, 絮凝剂体积为
20 mL(1 L 废水)的最佳处理条件下, 废水中COD 的脱除率达到98 %以上。

Abstract:

Two kinds of polymerization Mg-Al flocculants were synthesized under normal atmospheric temperature with slow-addition method, which is used on the laboratory wastewater COD removal examination. The results show that the COD removal is effected by flocculants kind, flocculants dose, pH, stirring time and settling time. Over 98% of COD is removed by polymerization sulfuric Mg-Al flocculants(PMAS) at pH=8, 3 minutes rapid agitation and 10 minutes slowly, 30 minutes settling time, 20 mL flocculants dosage in 1 L wastewater.
