摘　　要：污水厂进水易生物降解有机物(S S)含量低时难以保证污水处理效率,主要针对提高S S方法进行研究。采用铁碳微电解法作为污水的预处理工艺,考察不同pH、停留时间和Fe/C比对微电解系统处理效能的影响。结果表明,在进水pH为4,停留时间为90 min,Fe/C为4∶1时,S S提高率为35.4%,COD去除率为51.8%。模拟污水厂处理工艺,二沉池出水COD值为77.4 mg/L,增加铁碳微电解系统后二沉池出水COD值为48.9 mg/L。Less biodegradable organic matter depress the efficiency of wastewater treatment.The proportion of biodegradable organic matter.Iron-carbon micro-electrolysis process was employed for pretreatment process in a simulated wastewater treatment plant was aimed to enhance.Technological conditions of the influent pH,the influent HRT and the iron-carbon ratio were optimized.The results showed that the proportion of Ss and removal rate of COD was increased 35.4％ and 51.8％ respectively under the conditions of pH 4,HRT 90 min and the iron-carbon ratio 4：1.During the simulation of the sewage treatment plant,the effluent COD of secondary sedimentation tank was 77.4 mg/L,while it was reduced to 48.9 mg/L after adding the iron-carbon micro-electrolysis process.
