摘要
制药废水成分复杂,而且含有难生物降解和有抑制作用的抗生素等毒性污染物质,难以处理。采用水解酸化/改良SBR(MSBR)强/化絮凝组合工艺处理抗生素制药废水,结果表明:当进水COD≤500 mg/L、BOD5≤200 mg/L、NH3-N≤60 mg/L、PO34--P≤10 mg/L时,最终出水COD<100 mg/L、BOD5<20 mg/L、NH3-N<10 mg/L、PO34--P<0.8 mg/L,各项指标均达到《污水综合排放标准》(GB 8978—1996)的一级标准。
Pharmaceutical wastewater is difficult to be degraded because of the complicated composition and toxic pollutants, such as biorefractory and inhibiting antibiotics. The combined process of hydrolysis acidification, MSBR and enhanced floeculation was used to treat this wastewater. The results show that when the influent COD, BOD5 , NH3 - N and pO4^3- - P are equal to or less than 500 mg/L, 200 mg/L, 60 mg/L and 10 mg/L respectively, their final effluent indexes are less than 100 mg/L, 20 mg/L, 10 mg/L and 0.8 mg/L respectively, meeting the first level criteria specified in the Integrated Wastewater Discharge Standard （GB 8978 -1996）.
