Abstract:

At present,the research on steroid hormone pharmaceutical wastewater mainly focuses on the treatment of specific drug wastewater,the reduction of characteristic pollutants and the special treatment process. There were few reports on the standard treatment of all kinds of wastewater and the engineering design guidance. In this paper,the pilot-scale treatment of comprehensive wastewater from a steroid hormone pharmaceutical company was studied by using the combined process of primary sedimentation tank-micro-electrolysis/Fenton-hydrolytic acidification-anaerobic system-anoxic system-aerobic system-first-stage immobilized microorganism biological aerated filter(G-BAF)-micro-electrolysis/Fenton-second-stage(G-BAF). The designed treatment capacity of the pilot plant was 24 L/d,and the designed total hydraulic retention time of the process unit was 239.3 h. The actual operation results showed that,after the combined process,the removal rates of COD,NH3-N and TN were 99.1%,96.9% and 95.4%,respectively. The effluent COD,NH3-N and TN were 220,35 and 50 mg/L,respectively,which met the grade B standard of Indirect Discharge Standard of Water Pollutants in Chemical Synthesis Pharmaceutical Industry(DB 41/756—2012) in Henan Province.

摘要:

目前甾体激素类制药废水的处理研究主要集中在特定药品废水处理、特征污染物减量化或专项处理工艺方面,对相关的全类废水达标处理和工程设计指导方面的报道较为少见。对此,采用初沉池-微电解/Fenton-水解酸化-厌氧-缺氧-好氧-一级固定化微生物曝气生物滤池(G-BAF)-微电解/Fenton-二级(G-BAF)组合工艺对某甾体激素类制药厂的综合废水进行中试处理研究,中试装置设计处理规模为24 L/d,工艺单元设计总水力停留时间为239.3 h。实际运行结果表明,经组合工艺处理后,废水中COD、NH3-N、TN的去除率分别为99.1%、96.9%、95.4%,出水指标分别为220、35、50 mg/L,满足河南省《化学合成类制药工业水污染物间接排放标准》(DB 41/756—2012)B级标准。
