摘要
介绍了多级A/O+生物脱氮技术在高浓度制药废水处理工程中的应用。实际工程运行结果表明,处理出水pH值为6~9、COD≤500 mg/L、SS≤400 mg/L、氨氮≤35 mg/L、TN≤70 mg/L、TP≤8 mg/L,符合《污水综合排放标准》(GB 8978-1996)的三级标准,其中总氮、总磷达到《污水排入城镇下水道水质标准》(CJ 343-2010)的B级标准,氨氮达到《工业企业废水氮、磷污染物间接排放限值》(DB 33/887-2013)要求。该工程采用的点对点水解布水、生物脱氮、磁悬浮风机等新型技术和设备,具有较好的推广应用价值。
The application of multi-stage A/O and biological nitrogen removal technology in high concentration pharmaceutical wastewater treatment project was introduced.The practical operation results showed that the effluent pH was 6-9,and the effluent COD,SS,ammonia nitrogen,TN,TP concentrations were no more than 500 mg/L,400 mg/L,35 mg/L,70 mg/L,8 mg/L,respectively,which met the third-level standards of Integrated Wastewater Discharge Standard(GB 8978-1996).Among them,TN and TP met level B criteria in Wastewater Quality Standards for Discharge to Municipal Sewers(CJ 343-2010)and ammonia nitrogen met the requirements of Indirect Discharge for Emission Limitation of Nitrogen and Phosphorus for Industrial Wastewater(DB 33/887-2013).The new technologies and equipment applied in this process,such as point-to-point hydrolysis water distribution,biological nitrogen removal and magnetic suspension fan,have great application value.
