[Research on Fenton treatment of the biochemical processes effluent of bamboo industry wastewater].
The decolorization and organic matter reduction of bamboo wastewater using Fenton oxidation was studied. Considering the cost and the removal efficiency, the optimal conditions were t = 30 degrees C, pH = 3.5, p(H2O2) = 1 665 mg x L(-1), c(Fe2+)/c(H2O2) = 0.072 and reaction time 3 h, with an initial COD and color concentration of wastewater of 430 mg x L(-1) and 1 500 times, under these conditions, the removal efficiency of COD and color could achieve 87.5% and 94.4%, respectively. It was found that the color reduction was higher than that of organics, and less affected by operation factors. The GC-MS analysis revealed that the chromophoric groups and auxochromic groups were greatly removed after Fenton treatment. The intermediates were mainly ester derivatives, and the by-products included 1-iodo-tridecane and 1,1'-oxybisoctane.
