摘要
该研究对硅藻土进行酸改性,并用来预处理垃圾渗滤液。研究得出2 mol/L硫酸为最佳酸改性剂,酸改性硅藻土预处理垃圾渗滤液的最佳投加量为6 g/L,最佳pH为4.5,最佳搅拌时间为25 min,此时对垃圾渗滤液COD的去除率为33.1%,去除效果较为理想,具有一定的经济可行性。
In this study,the diatomite was modified by acid,and then it was used for the pretreatment of landfill leachate.It resulted that 2 mol/L sulfuric acid was the best acid modifier,the optimal dosage was 6 g/L,the optimum pH was 4.5 and the best mixing time was 25 min.In the case,the removal ratio of COD could get 33.1%,which was more desirable.Otherwise,the pretreatment of landfill leachate by the acid-modified diatomite has a certain degree of economic feasibility.
