絮凝法强化处理垃圾渗滤液的试验研究

Study on the Intensified Treatment of the Landfill Leachate with Flocculation Technology

絮凝法对垃圾渗滤液进行深度处理的研究中,分别对硫酸铝、聚丙烯酰胺进行了絮凝试验。结果表明:硫酸铝、聚丙烯酰胺各自单独作用时处理效果均不能达到要求,水样的pH对硫酸铝的絮凝效果有较大影响,而对聚丙烯酰胺的絮凝效果影响不大,当两者联合作用时,COD去除率可达到60%左右。

In the research of the intensified treatment of the landfill leachate with flocculation tech-nology,experiment of flocculant with aluminium sulphate and polyacry lamide has been conducted respectively.Results showed that both of the effects of the treatment could not meet the requirement and the pH of the water sampling affected the flocculant effect of alu-minium sulphate greatly,while almost hardly affects the polyacry lamide's.When the aluminium sulphate and polyacry lamide was used simultaneouly,the removal rate of COD can reach60%or more.
