摘要: 根據抗生素生產混合廢水的特點,采用水解酸化-膜生物反應器(MBR)工藝對混合廢水進行了工業化實驗,系統研究了多種抗生素混合廢水處理工藝的運行參數和處理效果.結果表明,當膜生物反應器的進水COD容積負荷7~10kg·m^-3·d^-1時,系統的COD去除率達到90%,NH₄-N和TN去除率分別達到80%和65%,出水水質滿足《GB18918-2002污水綜合排放標準》中二級標準的要求.

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.
