Efficacy of pre-treatment methods in the activated sludge removal of refractory compounds in coke-plant wastewater

, : Efficacy of pre-treatment methods in the activated sludge removal of refractory compounds in coke-plant wastewater. Water Research 28(3): 701-707

In this study, the possibility and mechanism of anaerobic acidification, ultraviolet radiation, and ozonation as pretreatment methods for improving the biotreatability of coke-plant wastewater have been investigated, a new process-A-A/O system-has been proposed and experiments in lab-scale apparatus and pilot plant have been conducted. It has been concluded that the tested A-A/O system is an efficient and cost-effective way for removing refractory organics from coke-plant wastewater.
