摘　　要：利用铁炭微电解反应器对印染废水的深度处理进行了实验研究,检验了微电解设备的性能,确定了其设备的最大负荷、反冲洗周期以及填料更换的周期,并对曝气影响反应器运行的状况进行了研究。该工艺对COD的去除率均达到70%以上,色度去除率为99%,盐度达1 000 mg/L以下,硬度达220 mg/L以下,出水水质达到印染废水的回用水质标准。The application of iron - carbon micro - electrolysis reactor to the advanced treatment of dyeing wastewater was studied. Performance of micro - electrolysis equipment was tested to determine the maximum hydraulic load, anti - wash cycle and filler replacement cycle. Operating conditions of the reactor impacted by aeration were also studied. The removal rates of COD and chroma reached 70% and 99% , respectively, the salinity and hardness were below 1 000 mg/L and 220 mg/L, respectively. The effluent quality met the reuse standard of printing and dyeing wastewater.
