摘要:

以干熄焦除尘焦粉为吸附剂,考察了焦粉对焦化废水中COD、挥发酚和氨氮的去除率,同时考察了焦粉的循环使用效果。在选定的实验条件下,焦粉对废水的COD、挥发酚和氨氮去除率分别为71.4%、76.9%、8.3%,焦粉需要再生后才能重复使用。

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.
