摘要
针对人工模拟的印染废水,设计了缺氧/好氧膜生物反应器相结合的处理装置。系统经过165d的运行,结果表明:系统对COD和氨氮一直有很好的去除效果,稳定期COD的去除率可以达到95.0%,NH4+-N平均去除率为96.5%,TP的平均去除率低于50%,TN的去除率处在60%~80%之间,活性艳红染料x-3B的去除率在60%~73%之间,出水含有少量色度。水样中长链的壬基酚聚氧乙烯醚NP10 E0的去除率可以达到99%,出水仅含有少量的NPlEO,NP:EO和NP。
Focusing on the simulated printing and dyeing wastewater, in this experiment, a wastewater treatment system was designed combined Anoxic/Aerobic process of membrane bioreactor. After running for 165 days, the results showed that: the removal efficiency of COD and NH4-N by this system was very outstanding. And in the stable period, the removal efficiency of COD could reach 95.0%, the average removal efficiency of NH4+-N was 96.5%. And the average removal efficiency of TP was below 50%. Moreover, the removal efficiency of TN was varied from 60.0% to 80.0%. The removal efficiency of reactive brilliant red X-3B was between 60% to 73%, the effluent contained a few chrominance. The final removal efficiency of NP10EO could reach 99% and the effluent only contained with low concentrations of NPIEO, NP2EO and NP.
