Problems solved by technology

However, the existing technologies mostly use methods such as microbial purification and natural aeration, which are slow, affected by environmental factors such as temperature and light, and have poor tolerance to extreme conditions, and are relatively space-consuming and bulky, so there are many limiting factors. unfavorable promotion

Embodiment

[0016] Example: refer to Figure 1 to Figure 2 , the industrial aquaculture water circulation device is applied to the industrial aquaculture water circulation device, the device has a culture pond 1 with water inlet and drainage device, wherein: the drainage device of the cultivation pond 1 is connected with the biochemical pool 3 through the solid-liquid separator 2; the biochemical pond 3 is also connected A diversion three-way valve 4 is connected; one passage of the diversion three-way valve 4 is directly connected to the return three-way valve 8 and returned to the culture pond 1; the other passage of the diversion three-way valve 4 can carry out supersaturated ozone disinfection on the culture water Then the ozone water treatment system that removes residual ozone and strong oxides in the water is connected with the backflow three-way valve 8 on demand.

[0017] The ozone water treatment system has an oxidation tower 5 that is connected with the diverter three-way valve...

Abstract

The invention discloses a factory aquaculture water circulating device. Aquaculture wastewater is subjected to solid-liquid separation treatment to remove most of solid particles, remaining soluble organic matters, ammonia nitrogen and nitrite nitrogen are primarily biologically treated, the soluble organic matters, the ammonia nitrogen and the nitrite nitrogen remaining in the aquaculture wastewater are subjected to ozone contact oxidation, and the aquaculture wastewater subjected to the ozone contact oxidation treatment is aerated to reduce or remove strong oxides which are produced by the ozone contact oxidation treatment and dissolved in the aquaculture water. The device has the advantages of novel structure, complete oxidizing substance degradation, low use cost, high safety, low environmental pressure and quick effect.

Description

technical field [0001] The invention relates to a purification device for intensive aquaculture water, in particular to a water circulation device for industrialized aquaculture. Background technique [0002] The core concept of the circulating water factory aquaculture system is based on seawater treatment and system control technology, to create a pure and stable water environment, to simulate the natural marine environment on which various seafood depends, so that it can be bred and grown in the most natural way. For example, such as the Chinese invention patent "A System for Ecological Treatment and Recycling of Industrialized Fish Farming Wastewater", patent number 200810008753.1. Oxygen supply devices, temperature control facilities, artificial wetlands and other circulating water treatment facilities and equipment; use open large-flow water supply channels and return channels instead of closed pipes. Use foam separation facilities to replace protein separators; use d...
