摘　　要：应用铁碳内电解法对安普霉素生产废水进行毒性去除及污染物处理,在固定铁屑和活性炭的体积比为1∶1的条件下,考察了水力停留时间(HRT)和pH对处理效果的影响.在对原水不进行pH调节的条件下,HRT为1 h时,铁碳内电解工艺对安普霉素废水中的COD和安普霉素去除率均可达50%以上,对NH3-N的去除率可达70%以上,废水可生化系数从处理前的0.26提高到处理后的0.45.产甲烷活性试验表明,经铁碳内电解工艺处理的废水,毒性消除,可以采用厌氧生物技术和好氧生物技术对其作进一步的有效处理.Iron internal electrolysis technology was evaluated for the pretreatment and toxicity reduction of apramycin wastewater. The volume ratio of Fe and C was fixed to 1 ： 1, and the effects of varying Hydraulic Retention Time （HRT） and pH value on pollutant removal efficiency were investigated under this condition. According to the experimental results, the optimum HRT was 1 hour, and the removal efficiencies of Chemical Oxygen Demand （COD） and apramycin were nearly independent on pH value at optimum HRT. The removal rates of COD and apramycin were above 50% and the removal rate of NH3 - N was above 70%. BOD5/COD ratio of the pretreated wastewater increased from 0. 26 to 0. 45. The results of methane formation toxicity experiment indicated that the toxicity of the pretreated effluent was reduced to a great extent and the pretreated wastewater was easily biodegradable to anaerobic microorganisms.
