摘要
用电渗析法处理高浓度氨氮废水。使用阴阳离子双隔膜三室电解槽,以铁作阳极,碳作阴极,把废水中的氨氮富集到阴极液中,在阳极中产生Fe2+,滴加H2O2后生成Fenton试剂,用以氧化降解废水中的有机物,6h可将垃圾渗滤液中的氨氮和CODCr同时除去80%。
NH3-N in garbage leachates was enriched in catholyte by electrodialysis in triple chambers cell equipped by coupling membranes, then removed by following chemical precipitation. CODCr was removed by Fenton reagent, which was generated in anodic chamber by dropping H2P2 to the anolyte to react with the dissolving Fe^2+ at anode. The results of experiment show that the removal rate of ammonia in simulate wastewater was up to 80% and CODcr and NH^4+ -N in garbage leachates were reduced efficiendy for 6 h.
