【摘要】 抗生素类发酵废水是一类富含难降解有机物和生物毒性物质的有机工业废水,具有治理难度大、处理成本高和有毒有害等特点。抗生素废水采用传统的废水处理工艺很难达标排放,废水的处理问题成为丁国内外研究的热点和难点。为有效解决抗生素生产废水的污染问题,科研机构及企业本身都进行丁不断的探索和研究.寻找有效的治污方法。本研究课题依托华北制药股份有限公司三废治理中心污水生化处理系统,首先分析了三废治理中心废水水质特点及废水处理系统不能达标排放的原因,从而开展高效微生物+A/O生化处理系统的探索和研究。研究的小试阶段进行了高效微生物菌种对青霉素为主的抗生素发酵废水的适应性试验；中试阶段开展了高效微生物+A/O生化处理系统在废水进水水量、水质波动大的条件下,在预定的运行参数条件下运行稳定性试验,得出了COD、NH3-N去除率达到试验要求,参数设定符合实际情况的结论。工程化运行在小试和中试实验结果及三废治理中心升级改造完成的基础上,在工程新增15000m3的好氧处理装置中接种高效微生物菌种,按设计要求开展生产性试验,测试新增的高效微生物处理装置和三废治理中心废水处理工艺的污染物去除率及技改完成后废水排放浓度。监测数据显示工程化试验阶段系统的废水处理量为6000-7000 m3.d-1之间,进水COD平均浓度在10000-20000 mg-L-1之间,NH3-N平均浓度在500-1000mg.L-1之间,操作参数pH值在8左右,出水水质COD浓度稳定保持在200-400 mg·L-1之间,NH3-N浓度稳定保持在10-20 mg.L-1之间,新增的“高效微生物+A/O生化处理”工艺的COD平均去除率达到85%以上,NH3-N平均去除率达到95%以上,技改工程完成后三废治理中心原水经厌氧水解、常规好氧曝气和高效微生物生化处理后COD平均去除率达到95%以上,NH3-N平均去除率达到98%以上,出水COD浓度控制在400 mg.L-1以内,NH3-N浓度控制在20 mg.L-1以内,出水水质达到预期的设计目标。研究结果表明,三废治理中心技改工程的高效微生物处理工艺及系统运行参数符合工程要求,应用高效微生物技术处理抗生素制药废水,处理效果显著,能有效保证出水水质稳定达标,该处理工艺解决了抗生素废水治理的难题,为有效解决抗生素类发酵废水的治理提供了有效手段。更多还原

【Abstract】 Antibiotic wastewater with high refractory and toxic Organic compounds is high cost and difficult to be treated by traditional biotreatment technology. The effective of traditional treatment technology also did not match the discharged standard. The low removal rate and effective is still important question in this field. Therefore. more attention should have been focused on the novel and cost-effective treatment technology.This experiment was conducted in the centre of three waste treatments in North China Pharmaceutical Company Ltd. First, the reason and question of the existed engineering was analyzed. Then the high effective micoorgannism with A/O biological treatment technology was studied in details. Last engineering was designed in light of the experiment and conducted to study the effect of the new technology. The results of lab scale and pilot scale experiments showed that the high effective micoorgannism with A/O biological treatment technology have high removal rate of COD、NH3-N and meeted to the decharged standard. The new construted aerobic bank of 1 5000 m3 was performed at the following inlet parameters:6 000～7000 m3·d-1, in 10 000～20 000 mg·L-1 COD, in 500～1 000 mg·L-1 NH3-N, pH of 8; and the outlet effective was 200～400 mg·L-1 COD and 10～20 mg·L-1 NH3-N. The removal rate of COD and NH3-N was 95～98% and 98～99%, respectively.Therefore, the high effective micoorgannism with A/O biological technology was very effectivly for the antibiotic wastewater treatment of the centre of three waste treatments in North China Pharmaceutical Company Ltd, and the designed engineering based on the new technology might match with the decharged standard and has the practical application and knowledge values for the similar engineering or wastewater.更多还原
