摘　　要：以含难降解有机物的港口化学品废水为研究对象,采用单因素实验和正交试验方法,研究了臭氧/活性炭催化氧化体系最佳运行参数及对废水降解效果,得到最佳运行方案为:体系pH为9,臭氧投加量700 mg/L,活性炭投加量20 g/L。以该方案连续运行30 d,废水CODCr去除率在55%~63%,出水CODCr在800~1250 mg/L,且B/C比由0.29提高至0.43,可生化性显著提高,为后续生化处理提供数据支持。The optimum operational parameters and degradation effect of catalytic oxidation of ozone/active carbon were studied by single factor experiment andorthogonal experiment,with port chemical water as subject.The result shows that the optimal working parameters are as follows:pH 9,ozone dosage 700 mg/L,catalyst dosage 20 g/L.With 30 days of continuous operation of the system,the COD removal rate was about 50%.Catalytic oxidation of ozone/activated carbon can increase the B/C ratio of wastewater from 0.29 to 0.43,which significantly improved the biodegradability of wastewater.
