水解酸化-膜生物反应器处理抗生素废水

Treatment of antibiotic wastewater with hydrolytic acidification membrane bioreactor

摘要: 根据抗生素生产混合废水的特点,采用水解酸化-膜生物反应器(MBR)工艺对混合废水进行了工业化实验,系统研究了多种抗生素混合废水处理工艺的运行参数和处理效果.结果表明,当膜生物反应器的进水COD容积负荷7~10kg·m^-3·d^-1时,系统的COD去除率达到90%,NH₄-N和TN去除率分别达到80%和65%,出水水质满足《GB18918-2002污水综合排放标准》中二级标准的要求.

Abstract: According to the characteristic of antibiotic wastewater, industrial experiment was carried out by hydrolytic acidification membrane bioreactor (MER) process. The MBR's running parameters and treatment effect were systematically investigated during the treatment. The results show that when the volume loading of the MBR is 7-10 kg·m^-3·d^-1, the removal rates of COD, NH₄-N and TN are up to 90%, 80% and 65%, respectively. The water quality of the effluent can meet the secondary discharge standard of the GB18918-2002 Integrated Wastewater Discharge Standard of China.
