中文摘要:
      近几年,国外的工厂化循环水养鱼系统中普遍采用了一种新型的水处理设备--蛋白质分离器(protein skimmer)[1].国内的一些单位已开始从德国、美国等引进小型的蛋白质分离器,并应用在水族馆及宾馆、饭店的观赏鱼的养殖中,使用效果较好.蛋白质分离器利用泡沫分离原理并与臭氧联合使用,可有效地去除水中的悬浮物、蛋白质和氨氮,并增加水中的溶解氧,同时具有杀菌消毒作用[2].
英文摘要:
      The water treatment effect of a protein skimmer with different ozone concentrations for recirculation system of industrial fish farming was studied in this paper. Foam separation principle and ammonia nitrogen removing theory of the protein skimmer was described. A protein skimmer with a discharge of 50 m^3?h^-1 was designed. The skimmer was used in a recirculation system, and relative water quality parameters:protein, ammonia nitrogen, nitrite, nitrate, organic nitrogen, suspended solid, dissolved oxygen, were tested. The results showed that the egesta of the fish reared and the feedstuff residual could be removed efficiently. The removal efficiency of ammonia nitrogen and protein in the recirculation system was very high by entering ozone into the protein skimmer. The removal rate of protein, ammonia nitrogen, nitrite, nitrate, organic nitrogen, suspended solid were various along with the different ozone concentrations. And the dissolved oxygen was greatly increased.
