ABR-生物接触氧化-BAF工艺处理中药提取废水实例

Wastewater Treatment Project for Use ABR & Bio-contact Oxidation & BAF Process on Extraction of Chinese Traditional Medicine

本文主要介绍了ABR+生物接触氧化+BAF工艺对中药提取废水的处理情况,工程实践表明,该工艺可以缓解水质变化及酸化对生化处理的冲击,对污染物有较高的去除率。出水可稳定达到《城镇污水处理厂污染物排放标准》(GB18918-2002)和《中药类制药工业水污染物排放标准》(GB21906-2008)较严值要求。

This paper introduced a wastewater treatment project case for use ABR bio-contact oxidation BAF process on extraction of Chinese traditional medicine. The engineering indicated that this process can mitigate the impact of water quality change and acidification on biochemical treatment, and had a higher removal rate of pollutants. The effluent can stably meet the stricter requirements for ＂Discharge standard of pollutants for municipal wastewater treatmentplant＂（GB18918-2002） and ＂Discharge standard of water pollutants for pharmaceutical industry Chinese traditional medicine category＂（GB21906-2008）.
