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(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.

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