| 摘 要： | 采用废铁屑-焦碳组成微电解工艺预处理高浓度酒精废液。通过正交试验和单因素分析试验考察了反应时间、铁碳比、曝气强度对铁碳微电解工艺降解有机物，提高废水可生化性和pH的影响，最终确定了最佳反应条件。试验结果表明，反应时间、铁碳比和曝气强度对铁碳微电解处理酒精废液的影响程度依次降低，且最佳反应条件为反应时间2小时，铁水比125：500，曝气强度4m^3／m^2h，CODcr的去除率达到50％，废水的BOD5／CODcr值可由O．3提升到0．48，pH由3．5提高到5．2左右。作为高浓度酒精废液预处理工艺，铁碳微电解能够经济、有效降低后续处理工艺的负荷，提高废水的可生化性和碱度。

| Abstract: | The micro-electrolysis process composed of waste iron and coke was adopted in pretreating high strength alcohol wastewater.The effects of reaction time,Fe/C ratio and aeration intensity on CODcr removal,biodegradability as well as pH value improvement were studied according to orthogonal and single factor test.The results showed that the influence sequence was reaction time at first,followed by Fe/C ratio,and aeration intensity was the lowest.Additionally,the optimum operation status were determined as foll... |
