预处理／复合水解酸化／复合好氧氧化工艺处理综合制药废水

针对传统水解酸化和好氧氧化处理工艺存在的问题,对水解酸化工艺及好氧氧化处理工艺进行了改进;并针对东北制药集团制药废水水质特征,设计开发了预处理 复合水解酸化 复合好氧氧化的生物处理技术。工程设计规模为30000 m3/d,两年的运行结果表明,此工艺运行稳定,耐冲击负荷能力强。当平均进水浓度COD为3600 mg/L、BOD5为1000 mg/L、SS为450 mg/L时,平均出水浓度COD≤300mg/L、BOD5≤100 mg/L、SS≤50 mg/L,达到了国家城市排水三级标准医药企业污水排放标准(COD300mg/L)。

Treatment of Synthetic Wastewater of Pharmacy by Pretreatment,Comprehensive Hydrolysis Acidation and Comprehensive Aerobic Oxidation

The traditional hydrolysis acidation and aerobic oxidation processes were improved.Based on analysis of wastewater from the Northeast General Pharmaceutical Factory,a complex process of pretreatment,comprehensive hydrolysis acidation and comprehensive aerobic oxidation was designed and applied in wastewater treatment engineering with capacities of 30 000 m3/d.Results of the two years operation showed that this process has property of stable efficiency and strong ability for resisting shock load.When average influent COD concentration was 3 600 mg/L,BOD5 was 1 000 mg/L and SS was 450 mg/L.The effluent concentration of COD was below 300 mg/L,BOD5 was below 100 mg/L,SS was below 50 mg/L.The effluent's concentration achieves the national pharmaceutical enterprises effluent standards for grade 3.
