CLR厌氧反应器在庆大霉素发酵废水处理中的运行效能
|
摘要
对CLR沼气提升式厌氧反应器处理硫酸庆大霉素发酵废水的工程运行效能进行了研究。结果表明,CLR反应器对硫酸庆大霉素废水具有较好的处理能力,容积COD负荷可达到5 kg/(m~3·d),出水COD稳定在2 700~3 200 mg/L,COD和SS去除率可分别维持在70%和62%左右。在CLR稳定运行过程中,系统p H为7.8~8.3,且VFA质量浓度低于900 mg/L,显示出较好的稳定性。虽然系统的氨氮质量浓度可以达到600~900 mg/L,但是其并未对CLR的处理效能产生显著影响。CLR出水Ca~(2+)质量浓度可稳定在200~300 mg/L,Ca~(2+)的平均截留率为74%。但是较高的进水Ca~(2+)质量浓度会导致污泥钙化,VSS/TSS逐渐下降,且这种趋势在反应器底部表现得更为显著。
The operational performance of Circular Lift Reactor(CLR) anaerobic reactor for gentamicin wastewater treatment was investigated in this study. The CLR anaerobic reactor exhibited a good efficiency in treating gentamicin wastewater. The volume loading rate(VLR) could reach to5 kg COD/(m~3·d) and the effluent with the level of chemical oxygen demand(COD) was within 2 500~3 200 mg/L. The removal efficiency for COD and SS reached as high as 70% and62%,respectively. The solution p H was kept at 7.8~8.3 and the content of VFA was below 900 mg/L in the stable operation duration,which showed a better stability of CLR anaerobic reactor. However,there was no significant influence to the processing efficiency of CLR anaerobic reactor. The effluent concentration of Ca~(2+)was maintained at 200~300 mg/L with an average rejection rate of Ca~(2+)of 74%.In the other side,the high influent concentration of Ca~(2+)would lead to the calcification of granular sludge and a gradual decline of VSS/TSS,which was more serious in the bottom of the reactor than that in the upper.
