摘要
采用厌氧-好氧处理系统可以有效地去除COD和四环素。当总停留时间为30h(其中厌氧段24h,好氧段6h),厌氧段采用中温35℃发酵时,容积负荷约为1.51kg COD/m^3·d。试验所用水样为四环素结晶母液经回收草酸,并稀释和调节pH后的水。厌氧菌对四环素的最大耐受浓度为300mg/L。
The anaerobic-aerobic process under study may effectively remove. COD and tetracycline from the tetracycline spent liquor. The total retention time for the liquor is 30h (24hfor anaerobic stage and 6h for the aerobic), the temperature for anaerobic stage is kept at 35℃ and the volumetricloading for COD is 1.51 kg/m3·d. After removal of oxalic acid, being diluted and its pH value adjusted, the tetracycline spent liquor is used as sample water. The maximum allowable concentration of tetracyline was found to be 300 mg/L for anaerobic digestion.
