【摘要】：针对高浓度医药废水,采用预处理+IC+CASS+BAF工艺可有效降解污染物,但由于排污标准的提高,水质不能达标,于是采用以下措施进行改造:将曝气生物滤池(BAF)单体分为三级,重新组合;向BAF各单体投加淀粉和高效脱氮除磷菌,增加碳源和微生物量;增设高效催化氧化反应池。经过调试,出水COD50 mg/L,氨氮2.5 mg/L,去除率分别为99.6%和99.1%,均可达标排放。
[Abstract]:For high concentration pharmaceutical wastewater, pretreatment with IC CASS BAF process can effectively degrade pollutants, but due to the improvement of sewage standards, the water quality is not up to standard. As a result, the following measures were adopted: the BAFs were divided into three levels and reassembled; Adding starch and high efficiency nitrogen and phosphorus removal bacteria to each monomer of BAF to increase carbon source and microbial biomass; After debugging, the effluent COD50 mg / L, ammonia nitrogen 2.5 mg / L, removal rates were 99.6% and 99.1, respectively.
