摘要：
针对中药生产废水色度高、有机物含量高的特点,采用电解气浮强化预处理—UBF—MBR工艺进行处理。工程实践表明:电解气浮强化预处理对COD和色度去除率分别为45%和80%左右,并且能改善废水的可生化性能,保证了后续生化的处理效果。该工艺可有效去除COD、BOD5、SS和色度,出水达到《中药类制药工业水污染物排放标准》(GB 21906—2008)中新建企业水污染物排放标准。

Abstract:
Traditional Chinese medicine wastewater with high chroma and high content of organic matter has been intensively pretreated by electrolysis-flotation，and then by UBF and MBR. The technological practice shows that the removal rates of COD and chroma by electrolytic-flotation enhanced pretreatment are about 45% and 80%，respectively，and the pretreatment improves the biodegradability of the wastewater to ensure the effect of the subsequent biochemical treatment. The process can remove COD，BOD5，SS and chroma effectively and its effluent can reach the discharge standard of water pollutants from new enterprises in the Discharge Standard of Water Pollutants from Pharmaceutical Industry of Chinese Medicine Category(GB 21906—2008).
