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2．5min时的45．15％、18．71％、8．50％，增加到水力停留时间为3．8min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。[著者文摘]

Water treatment efficiency of foam fractionator in the recirculating aquaculture system
SUN Da-chuan, WU Jia-min （ College of Aqua-life Science and Technology, Shanghai Fisheries University, Shanghai 200090, China）
Abstract:
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.[著者文摘]
