摘　　要：以中试试验为基础,在约6周时间内以生物预处理后出水和东江北干流枯水期河水两种不同水体作为系统试验原水,分两个不同阶段进行工程试验,考察臭氧-生物活性炭工艺(O3-BAC)处理净化微污染原水的性能与效果。浓度由低到高的原水试验结果表明,臭氧-生物活性炭工艺对CODMn和NH3-N的平均去除率分别均可达55%和80%以上;对NO2--N和浊度平均去除率也分别可达85%和95%以上,由此验证了臭氧-生物活性炭工艺是一种行之有效的处理微污染源水的深度处理技术。Based on the pilot scale experiment, with two kinds of water： effluent water after the biological pretreatment, water from north main stream of dongjiang river in low-flow period as experimental raw water respectively, the experiment of engineering in two different phases was carried out and lasted about 6 weeks so as to investigate the characteristics and the effect of ozone-biological activated carbon（O3-BAC） process treating micropolluted raw water. Using raw water with different mass concentration as the experimental water, the results showed that, the average removal rates of CODMn, NH3-N, NO2-N, and turbidity were above 55%, 80%, 85% and 95% respectively. So it was revealed that, ozone-biological activated carbon process was an effective and practical process for advanced treatment of micro-polluted source water.
