【Abstract】 This paper is aimed at systems of tiny pollute coking waste water which cannot be discharged after level I(chemical recover),level II(denitrification/nitration,or A/O technology) and chemical flocculation.With the study of dynamic membrane and its separation mechanism, chroma ≤50 (dilution multiple method) containing fluorine ≤6mg/L, cyanogens ≤0.5mg/L, COD cr≤100mg/L are available to coking waste water which conforms to the discharging standard or can be allowed for main drainage recycle.更多还原
