Abstract:

With coke breeze precipitated from CDQ dedusting as absorbent, the removal efficiency of COD,volatile phenol and NH3-N in coking waste water by CDQ coke breeze are investigated,including the coke breeze recycling condition.Under the required testing conditions,the removal efficiencies of COD,volatile phenol and NH3-N by coke breeze are measured 71.4%,76.9% and 8.3% respectively.Furthermore, the coke breeze can’t be recycled without regeneration.
