摘　　要：　为考察给水深度处理中活性炭单元在发挥吸附和生物作用的同时是否也能发挥过滤作用,以高藻源水为处理对象,对溶气气浮+活性炭过滤(工艺1)和溶气气浮+砂滤+活性炭过滤(工艺2)的处理效果和过滤单元的产水能力进行了比较。结果显示,两工艺的处理效果都比较好,而且差异不显著;工艺1中活性炭过滤单元的产水能力显著优于工艺2的砂滤单元。因此可初步断定,工艺1可以取代工艺2,即砂滤单元可以省掉。In order to investigate whether the GAC unit can give play to the filtration,while exerting adsorption and biological action in advanced water treatment,comparison was made on the treatment effect of dissolved air floatation + GAC filtration (process A) and dissolved air floatation + sand filtration + GAC filtration (process B),and water production capacity of filtering unit during high algae-laden raw water treatment.The result indicates that the two processes are good in treatment effect with little difference.Water production capacity of GAC filtering unit in process A is much more superior to that of sand filtering unit in process B.Therefore,it can be concluded roughly that the process A can be substi-(tuted) for process B,that is sand filtering unit can be omitted.
