A Review of Hybrid Process to Treat Coking Wastewater

Abstract:

Coking wastewater contains high concentration of refractory and toxic compounds. The effluent quality usually cannot meet the discharge limits after single conventional biological treatment processes. In order to find more effective coking wastewater treatment process, a serious hybrid treatment process were reviewed in this paper, which include: anoxic-anaerobic-oxic(A2/O) combined with membrane bioreactor (MBR); Fe/C micro electrolysis combined with Fenton process. Fenton oxidation combined with biologically process. Wastewater quality and operating parameters were compared. Through this review, we found that hybrid process is more efficiency to treat coking wastewater.
