摘　　要：采用复合式厌氧折板流和好氧曝气生物滤池的组合工艺(HABR-BAF)处理生物法烟气脱硫脱氮的循环液,研究最佳的工艺条件。结果表明:BAF装置中pH取6、C/N为10、溶解氧为2 mg/L、温度为28℃;HABR装置中pH取6、C/S为3、温度为32℃:双塔串联式生物法烟气同时脱硫脱氮系统的循环液混合液以先经过BAF装置再经过HABR装置的方式进行处理,最终SO2-4的去除率达86%,NO-3的去除率达99%。This paper aimed to research the combined process treating desulphurization and denitrification in series microbial tower and to acquire the optimal experiment conditions. The results indicated that the optimum process conditions of BAF were found when pH was 6 with 10 of C/N and 28℃ of T and 2mg/L of DO. The optimum process conditions of HABR were examined when pH was 6 with 3 of C/S and 32℃ of T. The removal rates of SO4^2- and NOx could reach 86% and 99% respectively when the mixed sewage first reacted in the BAF and then went through the HABR.
