高效降解菌耦合生物活性炭工艺深度处理化学合成类制药废水

生物活性炭工艺作为一种深度处理工艺，能够有效去除废水中的有机污染物，为了考察生物活性炭工艺对制药废水的深度处理效果，研究了高效降解菌对生物活性炭工艺污水处理效果的影响，并探讨了最佳运行参数。结果表明:高效降解菌的投加能够显著提高COD、氨氮等污染物去除效果。高效降解菌耦合生物活性炭工艺在填料填充度为80%，水力停留时间为10 h的工艺条件下，对COD、NH₃-N、AOX的平均去除率分别为38.2%、77.8%和84.3%，出水优于GB 8979-1996《污水综合排放标准》三级标准。

ADVANCED TREATMENT OF CHEMICALLY SYNTHESIZED PHARMACEUTICAL WASTEWATER BY HIGH EFFICIENT DEGRADATION BACTERIA COUPLED WITH BIOLOGICAL ACTIVATED CARBON PROCESS

As an advanced treatment process, biological activated carbon process can effectively remove organic pollutants from wastewater. In order to investigate the advanced treatment effect of biological activated carbon process on pharmaceutical wastewater, the effect of high-efficiency composite bacteria on wastewater treatment performance of biological activated carbon process was studied, and the influence of the operating parameters was discussed. The results showed that addition of composite bacteria could significantly improve pollutant removal effect. The high-efficiency degradation bacteria coupled with biological activated carbon process had an average removal rate of 38.2% for COD, 77.8% for ammonia nitrogen, and 84.3% for AOX under conditions of packing filling degree of 80% and hydraulic retention time of 10 h. The effluent was superior to the third-level limit value of China's Integrated Wastewater Discharge Standard (GB 8979-1996)。
