摘要: 高强度好氧反应器(jet-loop compact reactor,JLCR)采用射流曝气强制溶氧。对JLCR处理制药废水进行了试验研究,考察了JLCR的运行效果、反应器的启动与污泥驯化、抗冲击负荷性能以及污泥沉降性能等。初步结果表明,该系统启动时间较短,运行稳定,COD去除效果较好。进水COD为8000 mg/L左右时,去除率达到80%。Abstract: Aerobic jet-loop compact bioreactor(JLCR) can improve the concentration of dissolved oxygen in wastewater using the high strength jet flow.The wastewater from the process of pharmaceutic production was treated using JLCR. The operation, strat process, cultivation of sludge and organic loading were studied. The results show that the start time was short,the operation was stable and the removal rate was very high.While the COD of influent was 8000 mg/L,the removal rate of COD reached 80%.
