摘要:针对经 I级 (化学回收法 )、II级 (预反硝化 /硝化法 ,或称 A/O工艺 )和化学絮凝处理后的不能直接排放的轻污染焦化废水体系 ,通过研究动态膜及其分离机制 ,使废水色度≤ 50 (稀释倍数法 ) ,氟≤ 6mg/L,氰≤ 0 .5mg/L,CODcr≤ 1 0 0 mg/L。
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.
