摘　　要：对泡沫分离器生产运用中的注意事项进行了探讨,并对生产中不同工况下的水处理效果进行比较,结果表明泡沫分离器对水体中微小悬浮颗粒、溶解有机物有良好去除效果,并能脱去部分氨氮。在不同工况下,随着进水流量的减小,泡沫分离器对这三种水质指标的去除效率逐渐增加,分别由水力停留时间为2.5 min时的45.15%、18.71%、8.50%,增加到水力停留时间为3.8 min时的72.66%、34.11%、18.89%;同时,泡沫分离器不同工况对流经水体的溶解氧和pH都能有很好的调节作用。In this paper, the water treatment efficiency of foam fractionator under different work conditions was studied; at the same time, the working principle and the functions of it were discussed. The result of experimentation indicated that the foam fraetionator was in effect at removing of micro-suspended solids and COD, and also could take off some NH4^＋-N. Under the different conditions, the water treatment efficiency of foam fraetionator also increased along with the reducing of the water influent. The removal rates of SS, COD and NH4^＋ -N are increased respectively from 45.15%, 18.71% and 8.50% at 30 m^3/h influent（HRT：2.5 min） to 72. 66%, 34. 11% and 18. 89% at 20 m^3/h influent （HRT： 3. 0 min）; besides those, the foam fractionator also have good modulation and stabilization functions to DO and pH.
