摘　　要：试验以高藻水源水为处理对象,就两工艺流程(溶气气浮+活性炭过滤,溶气气浮+砂滤+活性炭过滤)对高藻原水中微量有机物的去除特性进行了考察。试验采用了强化混凝,气浮单元对有机物有一定去除效果,对DOC的去除率高于其它处理单元,而对于BDOC、AOC、HAAsFP,气浮单元的去除效果均弱于两流程的炭滤柱。流程2砂滤柱对有机物去除效果较差。对于试验考察的微量有机物,流程1的去除效果优于流程2,并且起主导作用的处理单元均为炭滤柱,而流程1炭滤柱的去除效果优于流程2炭滤柱。Characteristics of trace organics removal was studied during the treatment of algae-laden raw water with two process trains (dissolved air flotation GAC filtration, dissolved air flotation sand filtration +GAC filtration). Because of the application of enhanced coagulation, organics were removed by flotation, DOC removal by flotation was higher than that by any other treating unit; for BDOC, AOC, HAAsFP, removal by flotation was worse than that by any of the GAC filters in the two process trains. Poor organics removal was caused by sand filter in process train 2. Trace organics removal by process train 1 was better than that of process train 2, and most removal happened in GAC filters for both of the process trains, and removal by GAC filter in process train 1 was better than that by GAC filter in process train 2.
