摘要
为找出抗生素废水适合的生物处理方法,研究了水解酸化-厌氧-好氧组合工艺处理高浓度抗生素废水的试验.结果表明:采用相同体积(62 L)的升流厌氧污泥床和厌氧复合床(UBF)处理水解酸化后的抗生素废水,当COD容积负荷为6.0 kg/(m3.d)时,厌氧复合床对SS、COD、BOD5的去除率分别为75.6%、91.7%、96.1%;出水采用相同体积(64 L)的生物接触氧化反应器和周期循环活性污泥系统(CASS)进行处理,当COD容积负荷为1.6 kg/(m3.d)时,周期循环活性污泥系统对SS、COD、BOD5的去除率分别为91.6%、88.7%9、5.4%.结果表明UBF和CASS系统是抗生素废水处理中先进高效的生物反应器.
To find a suitable biotreatment process for antibiotic wastewater, acidification-anaerobic hydrolysis digestion process was used in this paper. A upflow anaerobic sludge blanket and a upflow blanket filter were used with the same volume（62 L） for treatment of antibiotic wastewater, when COD volume loading was 6.0 kg/（m^3·d）, the removal efficiency of UBF to SS,COD,BODs were 75.6 % ,91.7 %, 96.1% respectively. A biological contact oxidation process and a cyclic activated sludge system were used with the same volume （64 L） for treatment anaerobic bioreactors efflument, when COD volume loading was 1.6 kg/（m^3·d）, the removal efficiency of CASS to SS,COD,BOD5 were 91.6 % ,88.7 %, 95.4 % respectively. The results demonstrated that the UBF and CASS are advanced and efficient bioreactor.
