摘要
制备新型免烧型Fe0/C功能材料作为微电解反应器的填料处理丙烯腈废水。考察反应器进水丙烯腈废水的pH值、水力停留时间(hydraulic retention time,HRT)和曝气量等因素对丙烯腈降解效率的影响,并明确反应器的最佳运行参数;结合反应器的连续运行工况,考察制备的Fe0/C复合材料的稳定性及抗板结性能。结果表明,制备出的Fe0/C复合材料具有较好的强度,可以满足微电解填料应用于水处理的要求。最佳运行工况下,Fe0/C复合材料对化学需氧量CODCr和丙烯腈的去除效率可达65.8%和70.4%。反应器在连续运行过程中出水稳定;Fe0/C复合材料在反应器运行过程的稳定性良好,没有发生板结。
Un-sintered type Fe0/C composite was prepared in this study to be used as the micro-electrolysis fillers for acrylonitrile wastewater treatment.Effects of influent pH,hydraulic retention time(HRT)and aeration rate on chemical oxygen demand(CODCr)and acrylonitrile removal efficiency were investigated to determine the optimal conditions.The results indicated that the strength of Fe0/C composite met the water treatment fillers?requirements.Acrylonitrile wastewater was treated by the un-sintered type Fe0/C composite at optimal operating conditions(influent pH of 3,HRT of 6 h and aeration rate of 0.2 L/min),and the removal efficiencies of CODCr and acrylonitrile were calculated to be 65.8%and 70.4%,respectively.During the successive running of micro-electrolysis reactor,the treating performance for acrylonitrile wastewater was stable without the harden of Fe0/C composite.
