摘　　要：对滦河水进行 O_3—GAC 工艺深度处理中试研究表明：O_3—GAC 能在较长时间内保持对水中有机物的去除，COD_(Mn)的平均去除率为60.19%；TOC 的平均去除率为64%；UV_(254)的平均去除率为70.41%；NH_3-N 的平均去除率为53.83%；对水中的浊度和色度都有明显的去除效果，尤其臭氧化对改善难生物降解有机物的可生化性有十分显著的作用；O_3—GAC 能有效地去除饮用水中的有害、有毒物质，提高饮用水的安全性。Pilot plant research of ozonation activated carbon process(O_3/GAC)was conducted foradvanced treatment of polluted raw water of Luanhe River.The results showed that the removal abilityof organic substances of this process could conserve consistently for a long time,mean removal ratios of60.19%,64%,70.41% and 53.83% have been obtained for COD_(Mn),TOC,UV_(254) and NH_3-Nrespectively,and found that the combination process has obvious effect on removal of turbidity andcolority.Especially,the ozonation can significantly improve the biodegradability of refractory organicsubstances.O_3/GAC can effectively remove the hazardous and toxic substances from drinking water,and thus improve its safety.
