Fenton试剂强化微电解工艺预处理中纤板热磨废水
Micro-electrolysis treatment for hot, grinding wastewater from MDF production using Fenton's reagent
摘要
Abstract
The hot, grinding wastewater from medium density fiberboard (MDF) production contains high concentrated toxic oranic maters. It is not fit for biochemical treatment even after pretreatment of micro-electrolysis. Fenton's reagent method was employed to improve the former micro-electrolysis treatment by means of jar test. Optimal parameters of the Fenton process were determined as 0.05-0.10 of [Fe2+]/[H2O2] with 1 h reaction time. When Fenton treated effluent was controlled at pH 8.5, the sedimentation process further removed pollutants, and the chemical oxygen demand (COD) concentration of the former micro-electrolysis treatment effluent was reduced from 14 000 mg· L-1 to about 3 500 mg·L-1 . GC-MS analysis indicated that the combined process of micro-electrolysis and Fenton oxidation broke almost all of the monocyclic terpene bonds in the wastewater, oxidizing them to esters, alcohols, and ketones with a lower carbon number. However, for double ring terpense the combined process only broke some of the bonds. These obtained results evidenced the efficiency of the combined process to the hot, grinding wastewater pretreatment and should contribute to further studies of MDF wastewater treatment.
