| 摘 要： | 以北京某垃圾转运站的垃圾渗滤液原液为研究对象,采用催化湿式氧化技术进行实验研究。实验以Fe2+为催化剂,H2O2为氧化剂,在反应釜中高温高压处理转运站的渗滤液。同时,实验分别研究了反应温度、反应时间、催化剂种类和添加量等几种因素对渗滤液处理效果的影响。结果表明,当反应温度达到120℃,反应60 min时,在Fe2+催化条件下,按初始COD和Fe2+质量比为6投加催化剂,初始COD和H2O2当量比为1投加氧化剂,反应出水的COD去除率达到91%。

| Abstract: | Catalytic wet air oxidation technology was used to study the landfill leachate collected from a refuse transfer station in Beijing.This experiment was carried out in a high temperature and high pressure reactor,using Fe2+ as the catalyst and H2O2 as the oxidant.Meanwhile,the impacts of temperature,residence time,catalyst types and its dosing quantity on the degradation of leachate were researched.The results showed that when the temperature reached 120℃ and the residence time was 60 minutes,the COD removal rate of the effluent reached 91%,under the conditions of the mass ratio of Fe2+ was 1/6 and the equivalence ratio of H2O2 was 1 according to the initial COD of landfill leachate. |
