Description

Water treatment facilities is bred in fishery Technical Field The utility model relates to the technical field of aquaculture, in particular to a water treatment device for fishery cultivation. Background The quality of the cultured animals is controlled in a refined way, the influence of seasons, climates and the like on the cultured animals is reduced, and the industrial culture is often carried out by adopting an indoor pool system to replace an open-air pool. In order to save water and intensively treat pollutants, a circulating water culture system is commonly used in industrial culture, and the stability of the living environment of the cultured animals is dynamically maintained by circularly treating sewage in a water tank and supplementing the treated circulating water with normal parameters into the water tank. Along with the continuous improvement of the cultivation density, the traditional open type oxygenation facilities using air as a main oxygen source can not provide enough dissolved oxygen for cultivated animals, so that oxygenation equipment such as oxygen cones, low-head oxygenators and the like commonly use pure oxygen to replace air as an oxygen source, limit the oxygen to fully contact with water in a closed environment, and improve the utilization rate of the oxygen. The closed structure adopted by the pure oxygen oxygenation equipment cannot discharge carbon dioxide accumulated in the high-density aquaculture water body, and the high-concentration carbon dioxide not only can influence the PH value of the water body, but also has higher toxicity to aquatic organisms, especially cultured animals, so that the pure oxygen oxygenation equipment must be matched with the degassing equipment to be used together, and the occupied area is large.
