Wastewater reforming was done rationally on technological process and equipment for treating Vitamin C wastewater with full scale UBF. High concentration wastewater was mixed with recycle effluent from anaerobic treatment, so influent COD was reduced and total alkalinity was increased, meanwhile, appropriate hydraulic loading to the reactor was controlled during its running, thus treatment capacity of reactor was improved. Volumetric loading rate was raised from 6 0 kg COD/(m 3·d) to 10 0 kg COD/(m 3·d), biogas production rate was raised from 1 8 m 3/(m 3·d) to 3 2 m 3/(m 3·d), the amount of alkali and dilution water for adjusting pH were also reduced. 展开更多
