摘      要：Chroma is not effectively removed from Vitamin C(VC)wastewater by traditional anaerobic-aerobic *** means cur-rent treatment does not meet the strict new discharge standard for VC wastewater in ***,to date,no studies have investigated the removal of chroma from VC wastewater,or characterized the chromophoric organic matter in *** this study,choromophoric organic matter in effluent from anaerobic-aerobic treatment of Vitamin C wastewater was characterized using high performance gel permeation chromatography(HPGPC),ultrafiltration,and infrared(IR)and ultraviolet-visible(UV/Vis)*** water-quality indices were determined,and indicated that the organic matter in the effluent contained *** molecular weight of most organic matter in this effluent was below 1000 Da,while the remainder was between 1000-3000 *** compounds are likely biodegradation products of high molecular weight organic matter in the effluent,which are raw materials and byproducts from VC *** spectra indicated that the low molecular weight(1000 Da)organic matter and higher molecular weight(1000-3000 Da)organic matter contain similar major functional groups,including-OH,-NH2,-CO-NH2,-C=O-,and-COO-.The effluent was treated using electrolysis,and UV/Vis spectra of this effluent before and after electrolysis indicated that-C=O is an important chroma group in this *** can easily break-C=O,and provides a feasible technology for the advanced treatment of anaerobic-aerobic effluent from VC wastewater treatment.
