医药化工废水处理工程实例

摘要
医药化工的化学合成废水具有有机物浓度高、可生化性差、生物毒性强的特点,设计采用铁碳微电解-芬顿氧化-水解酸化-UASB-好氧处理工艺。运行实践表明,该工艺选择合理,处理出水COD、 BOD5的质量浓度分别为400～450、 100～150 mg/L,可稳定达到GB 8978—1996《污水综合排放标准》表4三级标准,满足下游工业园污水处理厂的进水要求。
As the chemical synthetic wastewater from pharmaceutical and chemical industry has characteristics of high organic matters concentration, poor biodegradability and strong biotoxicity, a process of iron-carbon micro-electrolysis-Fenton oxidation-hydrolytic acidification-UASA-aerobic method was adopted for its treatment.The practical running showed that, the said process was a suitable option, using it to treat the said kind of wastewater, the mass concentrations of COD and BOD5 were 400-450 and 100-150 mg/L respectively, which could not only stably meet the requirement of table 4 in grade Ⅲ of GB 8978—1996 Comprehensive Wastewater Discharge Standard, but also meet the quality requirement of downstream sewage treatment plant of the industrial park.
