摘　　要：采用Fe/C微电解-Fenton与O_(3)氧化耦合工艺预处理废润滑油再生废水,分别探讨了Fe/C微电解、Fenton和O_(3)氧化单独和耦合反应中工艺参数对处理效果的影响.试验结果表明,Fe/C微电解、Fenton、O3氧化及其耦合技术在最佳反应条件下CODcr去除率分别为45.1%、36.3%、28.7%和65.9%,相应的BOD_(5)/CODcr分别为0.33、0.21、0.28和0.47.3种技术单独使用均可有效去除废水CODcr且改善其可生化性,但处理效果明显不如耦合技术,且重复性试验表明其运行稳定性好.工程实例表明,废润滑油再生废水经该工艺预处理后,整体处理效果和经济效益俱佳.The Fe/C micro electrolysis-Fenton and O_(3) oxidation coupling process was applied to pretreat the waste lubricating oil regeneration wastewater,the influences of process parameters on the treatment effect in the individual and coupling reactions of Fe/C micro electrolysis,Fenton and O_(3) oxidation were investigated respectively.The results showed that under the optimal reaction condition,the removal rates of CODcr by Fe/C micro-electrolysis,Fenton,O_(3) oxidation and their coupling technologies were 45.1%,36.3%,28.7%and 65.9%,respectively,while the BOD_(5)/CODcr were 0.33,0.21,0.28 and 0.47,respectively.Although using three methods respectively could have certain effect on CODcr removal and biodegradability improvement of the wastewater,it was obviously not as effective as the coupling technology.Moreover,the repeated experiment showed that the operation stability of coupling reaction was stable.The project case indicated that after treated by the process,the treatment effect and economic benefits were good.
