摘要:

以硅藻土、ZSM5分子筛为载体,以 Fe(NO3)3·9H2O为 Fe源,制备了 Fe/硅藻土、Fe/ZSM5两种催化剂,分别与 H2O2组成非均相 Fenton体系处理垃圾渗滤液。研究了溶液 pH值、温度、H2O2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6g/L,H2O2加入量折合浓度为 02mol/L,反应时间 60min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%。

Abstract: Using diatomite and ZSM-5 molecular sieve as carriers and Fe(NO, ),9H,0 as the Fe sourceIwo catalysts, two catalysts , Fe/diatomite and Fe/ZSM-5 , were prepared to treat landfill leachate withH,0, in a non-homogeneous Fenton system. The effects of solution pH, temperature, H,0, dosage , cat.alyst 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 reach88. 78% and 92. 58% respectively under the conditions that the pH value of the solution system is 3.0the reaction temperature is 30 C , the equivalent concentration of catalyst dosage is 1. 6 g/L, the equiva-ent concentration of H,0, dosage is 0. 2 mol/L, and the reaction time is 60 min.
