【摘要】 某生物制药企业排放的生产废水中含乳酸链球菌素等大量抗生素和有机物,其COD、BOD5和Cl-均较高。该企业采用UV/TiO2/Fenton—水解酸化—UASB—A/O工艺进行处理。经过两年多的稳定运行,出水COD为92mg/L、BOD5为20mg/L、NH3-N为12mg/L,完全满足《污水综合排放标准》(GB8978—1996)的一级标准。此外,甲烷产气量达到300m3/d,可为热交换器提供能源。更多还原

【Abstract】 The wastewater from a biopharmaceutical enterprise has high concentration nisin and organic pollutants.The combined process of UV/TiO 2/Fenton+hydrolysis acidification+UASB+A/O was applied to treat this wastewater with high concentration COD,BOD 5 and chloride ion.After the stable operation for more than two years,the average concentrations of COD,BOD 5 and NH 3-N in the effluent are 92 mg/L,20 mg/L and 12 mg/L,respectively.The effluent quality achieves the first level criteria specified in Integrated Wastewater Discharge Standard(GB 8978-1996).Further more,the production of biogas is 300 m3/d,which can provide energy for heat exchanger.更多还原
