悬浮填料-SBR工艺处理难降解青霉素制药废水的研究

采用悬浮填料 SBR工艺处理青霉素制药废水 ,结果表明 :青霉素废水中含有的抗生素对微生物有抑制作用 ,宜采用非限制曝气的进水方式 ;最佳运行工艺为一周期 8h ,非限制曝气进水 1h ,反应 5h ,沉淀、排水和闲置 2h ;该工艺与单一SBR工艺相比 ,可提高CODCr去除率 2 0 %以上 ,缩短反应时间 2h ;且具有良好的稳定性 ,当进水CODCr浓度变化较大( 80 0— 2 5 0 0mg L)时 ,CODCr去除率一直稳定于 83 %— 85 %之间 ,出水CODCr在 136— 35 0mg L之间 ,达到国家二级排放标准。

The study on the treatment of penicillin-making wastewater by suspended bio-media-SBR

Suspended bio-media-SBR process was used to treat penicillin-making wastewater. The results demonstrated: the antibiotic of penicillin-making wastewater has inhibition on microorganisms, thus unlimited aeration filling pattern is more feasible; the operation strategy of the suspended bio-media-SBR consisted of 1 h filling, 5 h reacting, 2 h settling, drawing and idling. Compared with single SBR process, the system can increase COD Cr removal efficiency by more than 20% and reduce reaction time by about 2 h, In addition, the system showed good stability, when influent COD Cr concentration varied greatly from 800 to 2500 mg/L, COD Cr removal remained highly 83%-85% and COD Cr concentration of effluent was reduced to 136-350 mg/L.
