摘要 采用接触氧化-水解-MBR处理头孢类抗生素化学合成废水,设计进水量350m^3/d,实际处理水量385m^3/d。在进水COD为2125~11561mg/L(平均进水COD为4164mg/L)时,出水COD为79~282mg/L(平均出水COD为178mg/L),出水BOD5低于10mg/L,完全满足该工业园区污水纳管标准(COD≤300mg/L,BOD5≤100mg/L).在平均进水TN、ρ(NH4^+—N)和ρ(NO3^--N)分别为145.47,0.89,49.25mg/L时,平均出水分别为91.76,78.11,18.61mg/L,系统脱氮能力有限. The wastewater in chemical synthesis of cephalosporin was treated by contact oxidation - hydrolysis - MBR process. The design influent rate is 350 m^3/d and the practical treatment rate is 385 m^3/d. When the influent COD is 2 125 -11 561 mg/L (average 4 164 mg/L), the effluent COD is 79-282 mg/L (average 178 mg/L) and the effluent BOD5 is below 10 mg/L, which can meet the standards for the wastewater reception system in this industrial park (COD ≤300 mg/L, BOD5 ≤ 100 mg/L). When the average TN, ρ(NH4-N) and ρ(NO3-N) of the influent are 145.47, 0. 89, 49.25 mg/L respectively, those of the effluent are 91. 76, 78. 11, 18. 61 mg/L respectively, it indicates that the system has a limited ability of denitrogenation.
