Integrated circulating aquaculture water purification equipment

Abstract

The invention discloses integrated recirculating aquaculture water purification equipment which comprises a box body, and a first-stage filter box, a second-stage filter box and a third-stage filter box are arranged in the box body; a water inlet cabin and a filtering cabin are arranged in the primary filtering box, the water inlet cabin is communicated with a water outlet pipe of the aquaculturepond, and a drum-type micro-filter is arranged in the filtering cabin; the top of the secondary filter tank is communicated with the bottom of the filter cabin, and water filtered by the drum-type micro-filter enters the secondary filter tank; a filtering brush and a sterilization cabin are arranged in the second-stage filtering box, a sterilization device is arranged in the sterilization cabin, the second-stage filtering box is communicated with the third-stage filtering box, the water enters the third-stage filtering box after being filtered by the second-stage filtering box, and the third-stage filtering box is a biological filter and is used for removing harmful substances such as nitrogen, ammonia and nitrite in the water; an aeration device for providing oxygen for microorganisms inwater is arranged in the biofilter, the biofilter is further provided with a filter water outlet pipe, and the filter water outlet pipe is communicated with a water inlet pipe of the aquaculture pond,so that aquaculture sewage is purified integrally.

Description

technical field

[0001] The invention relates to the field of sewage treatment, in particular to an integrated circulating aquaculture water purification equipment. Background technique

[0002] Water is the living environment of aquatic animals, and water quality plays an important role in aquaculture. In the circulating aquaculture system, due to the accumulation of a large amount of fish feces, secretions, and residual bait during the breeding process, the ammonia nitrogen in the aquaculture circulating water will The concentration of nitrogen-containing pollutants such as nitrite and nitrite increases, which makes farmed fish prone to disease and even death. That is to say, the main factors affecting water quality in the aquaculture system are ammonia nitrogen, nitrite and fine particles. Therefore, it is necessary to efficiently remove various water-soluble Harmful pollutants appear to be crucial.

[0003] In the existing aquaculture system, it is mainly set outside the...
