摘要

本文研究了微波功率、臭氧和芬顿试剂在微波耦合臭氧和芬ton氧化过程中对渗滤液COD分解的影响。实验参数如pH、COD、温度、氧化剂用量、微波功率和反应时间都是不同的。结果表明,在微波处理中,在450 W、10分钟内COD去除率达到70%,在臭氧用量为159 mg/L、pH为11的条件下,60分钟COD去除率达57.4%。在Fenton工艺中,H2O2和Fe2+80 mµ/L在60分钟内对COD的去除率为52.91%。个别过程显示出不良反应时间消耗。通过三种工艺的比较,微波对COD的去除率较高,反应时间较短。在O3+Fe工艺中,反应时间为75分钟,COD去除率达到83%。实验表明,M+O3+Fe的联合作用可使渗滤液中的COD在较短的反应时间内分解。

Municipal solid waste leachate treatment using ultrasonication microwave & Ozonation combined Fenton process
ABSTRACT This work focus on the effect of Microwave power, Ozonation and Fenton reagent in microwave coupling Ozonation and Fenton oxidation process for the disintegration of COD of leachate. The experimental parameters like pH, COD, temperature, Oxidant dosage, microwave power and reaction time were varied. The results showed that 70% of COD removal efficiency was achieved at 450 W within 10 minutes interval in microwave process, 57.4% of COD removal efficiency was achieved at 60 minutes, ozone dosage 159 mg/L, pH 11. In Fenton Process, 52.91% COD removal efficiency at 60 minutes with H2O2 66.47 mµ/L and Fe2+ 80 mµ/L. Individual process showed an adverse reaction time consumption. On comparison of three processes, microwave achieved higher COD removal with shorter reaction time. In O3+ Fe process 83% COD removal was achieved at 75 minutes of reaction time. The experiment revealed the combined process of M+ O3+ Fe induces to the disintegration of COD in Leachate with a shorter reaction period.
