摘　　要：采用两级生物强化的好氧工艺处理高盐难降解三元前驱体生产废水,考察了白腐菌和嗜盐单胞菌在高盐环境下处理低浓度COD和氨氮的去除效果。结果表明:一级好氧阶段投加嗜盐单胞菌能够将生化系统COD去除率由20%~26%提高到40%~60%。经过驯化的活性污泥对氨氮的去除率可达90%以上,氨氮的去除能力与投加的嗜盐单胞菌及白腐菌无关。二级好氧阶段投加白腐菌能够继续提升COD去除率10%~40%,而投加白腐菌和嗜盐单胞菌可使出水COD去除率继续提升40%~60%,两菌可相互协同强化生化处理效果,并使其出水稳定达到国家排放标准。因此,采用投加白腐菌和嗜盐单胞菌的生物强化技术可有效提升三元前驱体生产废水中难降解COD去除效果。A two-stage aerobic bioaugmentation process was used to treat ternary precursor wastewater with high salinity and difficult biodegradation.The removal effect of Phanerochaete chrysosporium and Halobacillus sp.for the low-concentration COD and ammonia nitrogen in a high-salinity environment was discussed.The results showed that Halobacillus sp.could increase the COD removal rate of the biochemical system from 20%~26%to 40%~60%in the first aerobic stage.The ammonia nitrogen removal rate of acclimated activated sludge could reach more than 90%,however,the ammonia nitrogen removal effect had nothing to do with the addition of Phanerochaete chrysosporium and Halobacillus sp.The Phanerochaete chrysosporium could continue to improve the COD removal rate by 10%~40%in the secondary aerobic stage.And the cooperation of Phanerochaete chrysosporium and Halobacillus sp.could continue to improve the COD removal rate of effluent by 40%~60%.The research showed that the bio-intensification technology based on Phanerochaete chrysosporium and Halobacillus sp.could effectively remove the COD in the ternary precursor wastewater and met the discharge standard.
