摘　　要：采用浅层气浮／微电解／生化／过滤法处理广济药业维生素营养药类生产废水。系统对进水水质具有良好的抗冲击性能，浓浆经浅层气浮／微电解预处理后，对cOD的平均去除率达69．04％；系统最终出水水质能达到《污水综合排放标准》（GB8978—1996）的三级标准，对cOD的平均去除率达89．92％，部分指标如SS、色度、氨氮等达到了二级标准，对总磷的去除率达99．5％，彻底解决了现有工艺中经多效蒸发后存在难以处理的浓浆问题。同时处理费用由30～50元／m3降低到5．365元／m3。The combined process of shallow air flotation, microelectrolysis, biochemical treatment and filtration was applied to treat the pharmaceutical wastewater containing vitamin-type nutraceuticals from the Guangji Pharmaceutical Plant. The treatment system showed satisfactory performance of impact resistance. The average COD removal rate reached 69.04% after shallow air flotation and microelectrolys- is pretreatment. The final effluent water quality met the third class criteria specified in the Integrated Wastewater Discharge Standard （GB 8978 -1996）. The total COD removal rate was 89.92%, some in- dexes such as SS, color and ammonia nitrogen met the second class criteria, and the TP removal rate was 99.5 %. The problem of treating high-concentration liquid in the existing process was completely solved. Also, the treatment cost decreased from 30 - 50 yuan/m3 to 5. 365 yuan/m3.
