Abstract:

A pharmaceutical enterprise produces oral liquid, syrup and decoction for Chinese patent medicines. The combination process of internal circulation anaerobic reactor-biological contact oxidation-biological aerated filters was introduced in treatment of the Chinese patent medicine production wastewater in some pharmaceutical enterprise in Jiangxi Province, the treated water volume was 600 t/d. The operation results showed that the COD of influent wasterwater was 3 000-15 000 mg/L, the effluent COD was 55 mg/L and the removal rate was 99.48%, and the SS of influent wastewater was 500-1 200 mg/L, the effluent SS was 30 mg/L and the removal rate was 96.84%. The quality of the final effluent was stable and met the requirements of the standard of the Discharge of Water Pollutants in the Pharmaceutical Industry of Traditional Chinese Medicine(GB 21906-2008), the process cost was 3.57 yuan/m³.
