摘　　要：如何经济、有效地去除难降解有机物是当前水处理领域的难题之一。针对臭氧+FlopacTM工艺对化工废水难降解有机物的去除效果开展中试研究,并应用于具体工程实例。中试结果表明,增加臭氧投加量可有效提高化工废水的可生化性,当臭氧投加量由35 mg/L增加到75mg/L时,出水B/C值由0. 13提高到0. 17,对COD的去除率由27%提高到38%,出水COD浓度稳定在60 mg/L以下。实际工程运行数据表明,臭氧+Flopac^(TM)工艺可有效去除化工废水中的难降解有机物,出水水质稳定,臭氧投加量为65 mg/L、Flopac^(TM)平均滤速为6. 7 m/h时,COD去除率达到44%。Economic and effective removal of refractory organics is a challenging topic in wastewater treatment. The performance of the 03 ＋ FlopacTM process in removing refractory organics in wastewater of chemical industry was studied in both pilot experiment and actual project. The results showed that biodegradability of wastewater was improved by increasing the dosage of 03. When the dosage of 03 was increased from 35 mg/L to 75 mg/L, the effluent B/C ratio rose from 0.13 to 0.17 and the COD removal rate was improved from 27% to 38%, also the effluent COD was maintained below 60 mg/ L. Results from actual project demonstrated effective removal of refractory organics by the 03 ＋ FlopacTM process. When the ozone dosage was 65 mg/L and the filtration rate was 6.7 m/h, the total COD removal rate reached 44%.
