TOC and color in the bleaching effluent from straw pulp paper process could not reach draining standard after its treatment by a biochemical process. In this study, advanced treatment by integrated micro-electrolysis (Fe 0 ) method and Fenton-like process was investigated under various conditions, i.e. pH, Fe/C ratio, initial H_ 2 O_ 2 concentration and carrier gas. Results showed that Fe/C ratio(V/V= 1.5) , larger H_ 2 O_ 2 dosage around 50 mg/L, lower pH(pH=3) turned out to be particularly efficient. Temperature was a key parameter, remarkably increasing reaction rates. Carrier air not only improved reaction efficiency, but also saved H_ 2 O_ 2 dosage. Chlorinated organic compounds could be reductive dechlorinated by Fe 0 reaction and oxidated by ·OH produced from Fenton process. The combination of Fe 0 and H_2O_2 reactions had been proved to be highly effective for the advanced treatment of such a type of wastewaters, and important advantages concerning the application in the study.
