摘要
针对制药废水特征污染物浓度高、COD浓度高和可生化性差等特点,浙江某药业公司预先采用污水分流和分质处理,臭氧预氧化后综合废水处理量为250 m^3/d。其后通过水解酸化-厌氧-A/O组合工艺进行处理。运行结果表明,该工艺处理系统稳定,处理效果好,对COD和BOD_5平均去除率达91%以上,出水水质满足当地污水处理厂的纳管要求。
According to the characteristics of high pollutant concentration, COD concentration and poor biodegradability of pharmaceutical wastewater, the sewage was drained and treated separately in a pharmaceutical company in Zhejiang Province. A combined process of hydrolytic acidification, anaero- bic, and A/O was applied to treat 250 m3/d of comprehensive wastewater after pre-ozonation. Results from practical operation showed that the treatment process had the advantages of high stability arid efficiency. The average removal efficiency of both COD and BOD5 was greater than 91%. The final effluent could meet the inlet standard for local municipal sewage plant.
