Treatment of butyl xanthogenate wastewater by membrane bioreactor
摘要
Abstract
As a utility and high efficient wastewater treatment technology,membrane bioreactor (MBR) was applied to deal with high concentrations of simulated butyl xanthate wastewater for the first time.The effects of carbon source dosage,hydraulic retention time (HRT) and temperature on the biodegradation of butyl xanthate were investigated.And the mechanism of xanthate biodegradation by MBR was then conjectured based on hydrolysis character and oxidation feature of xanthate combined with experimental data.The results show that the optimum operating conditions are 0.5 g/L anhydrous sodium acetate as additional carbon source,HRT of 24 h,reaction temperature of 30 ℃,respectively.During steady-state phase of high volumetric load,the average effluent concentration of COD and butyl xanthenes concentration are 91.89 mg/L and 1.048-2.101 mg/L.The removal rate of COD and substrate butyl xanthate maintain at 94.0% and 99.7% respectively.The experiment provides the theoretical basis and prognosticates a good outlook of the MBR application on biodegradation of mine flotation wastewater.关键词
