乙酰螺旋霉素废水生物处理的试验研究

采用相同体积 (6 2L)的升流厌氧污泥床和厌氧复合床处理乙酰螺旋霉素废水 ,当容积负荷为 6 0kg(COD) (m3 ·d)时 ,升流厌氧污泥床和厌氧复合床反应器对SS、COD、BOD5的去除率分别为 6 7 4 %、85 1%、91 2 %和 75 6 %、91 7%、96 1%,结果表明厌氧复合床是高效实用的厌氧生物反应器 ;厌氧出水采用相同体积 (6 4L)的生物接触氧化工艺和周期循环活性污泥系统进行处理 ,当容积负荷为 1 6kg(COD) (m3 ·d)时 ,生物接触氧化反应器和周期循环活性污泥系统对SS、COD、BOD5的去除率分别为 87 9%、85 1%、92 8%和 91 6 %、88 7%、95 4 %,结果表明周期循环活性污泥系统是高效实用的好氧生物反应器 .

Study on a test of acetylspiromysin wastewater biotreatment

An upflow anaerobic sludge blanket and a upflow blanket filter with same volume(62L) were used to treat acetylspiromysin wastewater, when the volume laoding rate was 6.0kg(COD)/(m³·d),the removal efficiency of SS,COD,BOD₅ in the upflow anaerobic sludge blanket and the upflow blanket filter were 67.4%,85.1%,91.2% and 75.6%,91.7%,96.1% respectively, the test results demonstrated that the upflow blanket filter was more efficient anaerobic bioreactor. A biological contact oxidation process and a cyclic activated sludge system with same volume(64L) were used to treat the effluent in the anaerobic bioreactors,when the volume laoding rate was 1.6kg(COD)/(m³·d), the removal efficiency of SS, COD, BOD₅ in the biological contact oxidation process and the cyclic activated sludge system were 87.9%,85.1%,92.8% and 91.6%,88.7%,95.4% respectively, the test results demonstrated that the cyclic activated sludge system was more efficient aerobic bioreactor.
