    • A fish rearing system having a water circulation system comprising: a trapping section including a particle trap 2 for capturing residual feed and fish feces contained in the water, a sediment trap 6 for accumulating a sediment in a rearing tank and separating the sediment from the water, a residual feed detecting sensor 5 interposed in a pipe 4 communicating with the particle trap 2 and the sediment trap 6, and a micro-screen filter 7; a denitrification device 12 for denitrifying a nitrogen compound dissolved and contained in the water; a bubble surfacing device 11 for generating bubbles by supplying air and/or ozone and removing surface active substances contained in the water by capturing the bubbles; an ultraviolet disinfection device 13 for disinfecting the circulating rearing water; an ammonium treatment section consisting of a immersion treatment device 15 and a non-immersion treatment device 14 and having a function of decomposing ammonium contained in the water; and an aeration device 21 for dissolving oxygen into the water; wherein the denitrification device 12 is disposed at the upstream of the bubble surfacing device 11 and includes a bypass pipe 10. Thus, the fish rearing system capable of performing water quality control at a low cost can be obtained by a rational combination of devices.
    • 一种具有水循环系统的鱼饲养系统,包括:捕集部分,包括用于捕获残留饲料的颗粒捕获器2和包含在水中的鱼粪;沉淀池6,用于在饲养槽中积聚沉淀物并将沉淀物与水分离 插入与颗粒捕集器2和沉淀物捕集器6连通的管4中的残留进料检测传感器5和微滤器7; 用于使溶解并包含在水中的氮化合物脱氮的脱氮装置12; 用于通过供应空气和/或臭氧并通过捕获气泡去除包含在水中的表面活性物质来产生气泡的气泡表面装置11; 用于对循环饲养水进行消毒的紫外消毒装置13; 由浸渍处理装置15和非浸渍处理装置14构成的具有分解水分中的铵的功能的铵处理部, 以及用于将氧气溶解到水中的曝气装置21; 其中脱氮装置12设置在气泡堆积装置11的上游,并且包括旁通管10.因此,能够以低成本执行水质控制的鱼饲养系统可以通过装置的合理组合来获得。
