复合絮凝剂处理印染废水的应用研究

Application Study on the Treatment of Wastewater From Printing and Dyeing Mill by a Novel Composite Coagulant

以硅酸钠、稀硫酸、硫酸铝和硫酸锌为原料制备一种新型无机高分子混凝剂———聚硅酸铝锌 (PSAZ) ,试验了它的混凝除浊性能和对印染废水的处理效果 .结果表明 :PSAZ具有良好的混凝脱色能力 ,用于处理印染废水 ,pH适用范围宽 ,用量少 ,混凝效果好 .

The coagulation effect of polysilicate aluminum zinic(PSAZ) is studied in the treatment of printing and dyeing wastewater. The experimental results show that the wastewater pretreated by PSAZ and CPAM can meet the discharge standards resulting in the good treatment effect.
