The present invention relates to an aquaculture water treatment and oxygen increasing apparatus, mainly involving the use of a water flow generating device. Because flow channels within the water flow generating device have different diameters, a pressure difference can be generated to bring the outside air into the water and mix them uniformly for producing a large amount of fine bubbles, which are then transported and dispersed into the water through a distributed configuration of ducts. Also, the potential energy due to the difference between the inside and outside water level generated by this water flow generating device can be used to produce the DO (dissolved oxygen) phenomenon for facilitating nitrification, and the effects of filtering and optimizing the living environment for nitrobacteria in the device can be achieved by subjecting to cotton filters or biological filter, thus making the aquaculture pond to have a large area of dissolved oxygen and high dissolved oxygen efficiency, so that sufficient dissolved oxygen may exist in the pond bottom therefore, it is possible to transform the highly toxic ammonia nitrogen into nitric acid of low toxicity, delay the formation of hydrogen sulfide, and purify the water, so as to improve the survival rate of aquaculture and reduce aquaculture water consumption. In short, this invention meets requirements of novelty, inventive step, and industrial applicability.本發明係有關一種養殖用水質處理及增氧裝置,其主要包括一種利用水流產生裝置,藉由水流產生裝置內流道之管徑不同,而產生壓差,進而將外部之空氣帶入與水均勻混合產生大量細微氣泡,並透過分佈設置之導管將細微氣泡運送分散至水體中,並藉由水流產生裝置所產生之內外水位差,運用其位能產生溶氧現象以利硝化作用,再通過濾棉或生物濾材,具有過濾及優化裝置中硝化菌生存環境之功效,可達到使養殖池溶氧面積大、溶氧效率高、使池底溶氧充足與轉化毒性高之氨態氮成毒性低之硝酸並延緩硫化氫的形成及淨化水質,以提高養殖生物存活率及減少養殖用水量,為一甚具新穎性、進步性及可供產業上應用之發明。(1)‧‧‧水流產生裝置(11)‧‧‧外殼本體(111)‧‧‧水流入口(12)‧‧‧流道(13)‧‧‧馬達(131)‧‧‧驅動軸(132)‧‧‧流水驅動裝置(14)‧‧‧流體壓差元件(141)‧‧‧入口(142)‧‧‧內徑較小部(143)‧‧‧進氣孔(15)‧‧‧空氣管(16)‧‧‧過濾棉(17)‧‧‧生物濾材(18)‧‧‧導管(2)‧‧‧水(21)‧‧‧細微氣泡
