摘　　要：研究了以UV(紫外线)照射、O_3氧化及厌氧酸化作为预处理方法来提高焦化废水生物降解性能的可行性和作用机理,并由此提出了一条新的工艺路线:A-A/O工艺。研究表明,以A-A/O工艺去除焦化废水中的难降解有机物效果显著,经济可行。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.
