沸石联合硫酸铝处理生活污水技术初探

Treatment of Sewage Using Zeolite and Aluminum Sulfate

[目的]探讨沸石联合无机絮凝剂硫酸铝处理生活污水的最佳投加比例。[方法]将沸石和硫酸铝联合起来处理生活污水,通过分析絮凝率的变化,研究二者联合使用的最佳投加比例。[结果]沸石和硫酸铝联合使用的最佳投加比例为1∶1,此时絮凝率高达98%以上。沸石联合硫酸铝处理生活污水不仅可以提高污水的处理效果,而且降低了化学絮凝剂的用量,从而减少了化学絮凝剂的二次排放,并降低了经济成本。[结论]该研究为今后生活污水的有效处理提供了理论依据。

[Objective] The study aimed to discuss the optimum ratio of zeolite to aluminum sulfate dosage in sewage treatment.[Method] Zeolite and aluminum sulfate were combined to treat sewage,and flocculation rate of sewage was calculated to analyze the optimum ratio of zeolite to aluminum sulfate dosage.[Result] The best ratio of zeolite to aluminum sulfate dosage in sewage treatment is 1∶ 1,and the flocculationrate is the highest,reaching above 98％.Using zeolite and aluminum sulfate to treat sewage can not only improve treatment effect,but also reduce aluminum sulfate dosage,thereby decreasing secondary emission of aluminum sulfate and economic cost.[Conclusion] The research can provide theoretical references for effective treatment of sewage in future.
