Aerating device of water body and aeration filtering device of water body

Abstract

The invention discloses an aerating device of a water body. The aerating device comprises an aerating container and a breeding container, wherein the aerating container and the breeding container are respectively communicated with a water inlet pipe through a water return pipe; oxygen is filled in the aerating container; a pipe opening of the water inlet pipe entering the aerating container has a spraying structure and / or a fog jetting structure; the water return pipe has a connector structure and forms liquid seal corresponding to the oxygen in the aerating container by collecting the water body; the water body in the breeding container is pumped into the aerating container through a pump and then returned to the breeding container through the water return pipe after being sprayed and aerated. According to the invention, on one hand, an aeration filtering device of the water body capable of improving dissolved oxygen, filtering quality of water and utilization rate of resource is provided. The aeration filtering device has the above structure, wherein multiple layers of filter materials are arranged inside the aerating container from down to up. According to the scheme, the structure is simple and the cost is low, the oxygen dissolving effect, the filter effect and the sterilizing and disinfecting effects are excellent, the oxygen utilization rate is high, and the water resource is remarkably saved.

Description

technical field [0001] The invention relates to an oxygenation technology for a fish breeding water body, in particular to an efficient and economical water body oxygenation device utilizing oxygen. Background technique [0002] The amount of dissolved oxygen in aquaculture water and the quality of water filtration directly affect the effect of fish farming, while oxygenation, filtration methods and devices directly affect the amount of dissolved oxygen and the quality of water quality. Better now, factory fish farming utilizes pure oxygen to pass into the method for aquaculture water body oxygenation, and there are still many deficiencies in effect and benefit. The main manifestations are: the contact surface between oxygen and water is small and the time is short, most of the oxygen is directly lost in the air after leaving the water body, resulting in less dissolved oxygen, more waste, and low utilization rate; industrial fish farming must build a powerful filter The sys...
