摘　　要：为降解MDEA脱硫液中的有机污染物,通过培养好氧颗粒污泥。实验中调节生长条件,在配置的葡萄糖废水中培养出高效颗粒污泥,COD降解率达70%。经不同浓度梯度替换,培养出对实际MDEA脱硫液有降解效果的微生物,降解效率降至30%~50%。实验中MDEA废液COD浓度为500mg/L时,污泥降解效率最高为48.1%。To degrade organic pollutants in MDEA desulfurization solution,aerobic granular sludge was cultured through experiments.In the experiment,the growth conditions were adjusted,and the highly efficient granular sludge was cultivated in the glucose wastewater,and the COD degradation rate was 70%.After replacing with different concentration gradients,microorganisms with degradation effects on the actual MDEA desulfurization solution were cultivated,and the degradation efficiency decreased to 30~50%.When the COD concentration of MDEA wastewater in the experiment is 500mg/L,the highest sludge degradation efficiency is 48.1%.
