摘　　要：延迟焦化含硫污水中焦粉、油、硫化物等污染物含量高,焦粉和焦油的粒径较小,乳化油占比较大,污水流量波动大,导致焦化含硫污水的预处理难度较大。介绍了焦化含硫污水的常规处理技术和部分新型处理技术,其中旋流溶气气浮、陶瓷膜处理技术具有良好的处理效果,值得推广应用。The pre-treatment of sulfur-bearing wastewater from delayed coking unit is difficult because of its features such as high concentration of coke powder,oil and sulfide,small particle diameter of coke powder and oil,large proportion of emulsified oil,large volume fluctuation,and so on.The conventional treatment technologies and some new treatment technologies of sulfur-bearing wastewater from delayed coking unit were introduced briefly.Swirl dissolved air floatation method and ceramic membrane treatment method achieved good results,which were worthy of spreading to application.
