摘　　要：以硅藻土、ZSM-5分子筛为载体,以Fe(NO_(3))_(3)·9H_(2)O为Fe源,制备了Fe/硅藻土、Fe/ZSM-5两种催化剂,分别与H_(2)O_(2)组成非均相Fenton体系处理垃圾渗滤液。研究了溶液pH值、温度、H_(2)O_(2)用量、催化剂加入量和反应时间对垃圾渗滤液COD去除效果的影响。实验结果表明:利用该非均相Fenton体系处理COD浓度为1110mg/L的垃圾渗滤液,在溶液体系pH值为3.0,反应温度30℃,催化剂投加量折合浓度为1.6 g/L,H_(2)O_(2)加入量折合浓度为0.2 mol/L,反应时间60 min的条件下,Fe/硅藻土、Fe/ZSM-5两种催化剂处理垃圾渗滤液COD去除率可分别达到88.78%和92.58%。Using diatomite and ZSM-5 molecular sieve as carriers and Fe(NO_(3))_(3)·9H_(2)O as the Fe source Two catalysts,two catalysts,Fe/diatomite and Fe/ZSM-5,were prepared to treat landfill leachate with H_(2)O_(2)in a non-homogeneous Fenton system.The effects of solution pH,temperature,H_(2)O_(2)dosage,catalyst addition and reaction time on the COD removal of landfill leachate were investigated.The experimental results show that the COD removal rates of Fe/diatomite and Fe/ZSM-5 catalysts can reach 88.78%and 92.58%respectively under the conditions that the pH value of the solution system is 3.0,the reaction temperature is 30℃,the equivalent concentration of catalyst dosage is 1.6 g/L,the equivalent concentration of H_(2)O_(2)dosage is 0.2 mol/L,and the reaction time is 60 min.
