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。
該研究對硅藻土進行痠改性,併用來預處理垃圾滲濾液。研究得齣2 mol/L硫痠為最佳痠改性劑,痠改性硅藻土預處理垃圾滲濾液的最佳投加量為6 g/L,最佳pH為4.5,最佳攪拌時間為25 min,此時對垃圾滲濾液COD的去除率為33.1%,去除效果較為理想,具有一定的經濟可行性。
해연구대규조토진행산개성,병용래예처리랄급삼려액。연구득출2 mol/L류산위최가산개성제,산개성규조토예처리랄급삼려액적최가투가량위6 g/L,최가pH위4.5,최가교반시간위25 min,차시대랄급삼려액COD적거제솔위33.1%,거제효과교위이상,구유일정적경제가행성。
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.
