摘要： 探讨利用膜生物反应器(MBR)处理丁基黄药(简称黄药)废水时的启动期及好氧活性污泥驯化过程的运行特征,分析其好氧活性污泥的形成过程、形态特征、性质及对污染物的去除机制.以啤酒污水处理曝气池污泥为接种污泥,以乙酸钠和黄药为碳源,培养及驯化絮体污泥.结果表明,MBR系统经过35 d启动及驯化即可达到正常运行状态,絮体污泥的SVI为100 mL/g,MLVSS/MLSS为0.75,生物量大且沉降性良好,COD及黄药去除率分别可以达到80%和90%.絮体污泥的形成及膜的高效截留增强了MBR运行的稳定性,为黄药废水的高效降解提供了保证.

Abstract: Operating characteristics of acclimation processes of the aerobic activated sludge and the start-up period of the treatment of the butyl xanthogenate wastewater using membrane bioreactor (MBR) were discussed. The formation, morphology, character and mechanism for the pollutant removal of the aerobic active sludge using MBR were analyzed. Floccule sludge was acclimated using beer wastewater treatment aeration tank sludge as the inoculum sludge and with the sodium acetate and butyl xanthogenate as the carbon sources. The results showed that after 35 days start-up period and acclimated, the MBR system reached normal operating state with the SVI of the floc sludge of 100 mL/g and MLVSS/MLSS of 0.75, the removal rates of COD and xanthogenate of 80% and 90% respectively. The formation of floc sludge and membrane efficient rejection enhanced the stability of the MBR and provided a guarantee for the efficient degradation of the xanthogenate wastewater.
