| Abstract: | In this study, the possibility and mechanism of anaerobic acidification, ultraviolet radiation, and ozonation as pretreatment methods for improving the biotreatabi lity 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 waste-water. |
