摘要

某电厂工业废水中有机物含量较高

而BOD5/COD(B/C)很低

直接生物处理效果不佳。对此，本文通过臭氧氧化提高废水中难降解有机物的可生化性

再联合生物活性炭(BAC)工艺处理该废水

同时对臭氧接触氧化时间、原水pH值及臭氧投加量对氧化效果的影响

以及对臭氧-生物活性炭工艺(O3-BAC)的整体性能进行了分析研究。结果表明：臭氧氧化最佳工艺条件为臭氧接触氧化时间15 min、原水pH值约为8.00、按O3/TOC质量比为3.0投加臭氧；臭氧氧化后原水B/C值可提高到0.21左右，总有机碳(TOC)的去除率为33.95％

化学需氧量(COD)的去除率为47.69％；O3-BAC工艺在进水流量为0.60 L/h时对有机物的去除效果最优

产水TOC质量浓度平均约为11.30 mg/L

对TOC的去除率高达70％；产水COD质量浓度平均约为42.00 mg/L，对COD的去除率约为68％；原水浊度平均降低87.08％。O3-BAC工艺运行期间，产水温度、pH值、溶解氧量在正常范围内，表明O3-BAC工艺运行稳定。
