摘要/Abstract

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COD_Cr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。

Abstract: 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(COD_Cr)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 COD_Cr 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.

Key words: micro-electrolysis, reactor, acrylonitrile, un-sintered, anti-harden
