摘要： 针对传统铁碳微电解装置存在的偏流、堵塞、填料板结等问题，对装置结构进行优化，采用催化微电解填料对络合铜废水进行了预处理。在装置内部增加挡圈防止设备偏流，增设废水内循环工艺防止设备堵塞，改变填料的结构防止设备板结，采用催化微电解填料提高反应速率。在此基础上，研究了不同催化填料、进水浓度、反应时间及pH对微电解反应过程的影响。结果表明，采用铁碳填料、络合铜的质量浓度为10 mg/L、反应时间为60 min、pH为3.0时，反应达到最佳状态，出水能够达到《电镀污染物排放标准》（GB 21900-2008），设备运行稳定可靠。

Abstract: Aiming at the probelm that bias current,clogging,filler hardening,etc. existed in the conventional iron-carbon micro-electrolysis device,the device structure has been optimized,and catalytic micro-electrolysis filler used for the pretreatment of the complex copper wastewater. The retainer ring was added inside the reactor to prevent the device from bias current,wastewater internal circulation process added to prevent the equipment from clogging,the structure of the filler changed to prevent the equipment from hardening,and the catalytic micro-electrolysis used for improving the reaction rate. On this basis,the influences of different catalytic fillers,concentration of influent,reaction time and pH value on the micro-electrolysis reaction process have been investigated. The results indicate that when iron carbon fillers are used,the optimal reaction conditions are as follows,the mass concentration of complex copper is 10 mg/L,reaction time 60 min,and pH=3,the reaction state reaches the Pollutant Discharge Standard for Electroplating(GB 21900-2008),and the equipment runs stably and reliablely.
