Problems solved by technology

In the prior art, the water to be treated is passed through the filter sieve to remove a certain amount of large particles of solid matter, but the tiny particles below 30 μm cannot be removed. If the mesh of the filter sieve is too fine, it is prone to clogging and delays the flow of water. treatment time, reducing the quality of water treatment

Embodiment Construction

[0033] The present invention will be further described below in conjunction with specific examples.

[0034] Such as figure 1 , figure 2 and image 3 As shown, an integrated removal device for carbon dioxide and tiny particles in seawater aquaculture is characterized in that:

[0035] The integrated removal device is a cylindrical tank as a whole, and is provided with a sewage discharge section, an air distribution section, a water inlet section, a packing section and a foam collection section in sequence from bottom to top.

[0036] The sewage discharge section is a conical sewage discharge tank 1, and the conical bottom of the sewage discharge tank 1 is connected with the sewage discharge pipe 2 and leads to the outside of the tank. The dirt deposited at the bottom of the conical sewage tank can be discharged out of the tank at any time.

[0037] The air distribution section is composed of several air distribution pipes 3 which are horizontally criss-crossed and interco...

Abstract

The invention relates to an integrated removing device for carbon dioxide and tiny particulate matter in mariculture, and belongs to the technical field of aquaculture equipment. The integrated removing device is a cylindrical groove body and is provided with a pollution discharge section, an air distribution section, a water inlet section, a padding section and a foam collection section sequentially from bottom to top. According to the integrated removing device, a fan supplies air to the air distribution section, and bubbles are formed in water and form contact reaction with inlet water flow. Due to the fact that the concentration of the carbon dioxide in aquatic water is much higher than that in air, according to the dual mode theory of gas-liquid transferring, the carbon dioxide is transferred from the liquid phase to the gas phase, and the degassing effect is generated. Due to the effect of the surface tension of sea water, the tiny suspended particulate matter, organic matter, grease and the like can adhere to a lot of the tiny bubbles formed by the integrated removing device well. Foam carrying the pollutants can be separated from the water and accumulates on the water surface along with ascent of the bubbles, and therefore when the foam is removed, the pollutants adhering to the foam are removed.

Description

technical field [0001] The invention relates to an integrated removal device for carbon dioxide and tiny particles in seawater aquaculture, and belongs to the technical field of aquaculture equipment. Background technique [0002] China has become the world's largest aquaculture country, accounting for about 70% of the world's total aquaculture. How to change the existing farming model, improve the automation of farming operations and the effect of water treatment will have a significant impact on the current development of aquaculture in my country. Carbon dioxide and tiny particles in aquaculture water will have a greater impact on water quality and the survival and growth of fish. High concentration of CO 2 It is harmful to the fish. When it exceeds the tolerance level of the fish, it will significantly reduce the oxygen transport capacity of the blood of the fish. In severe cases, it will cause suffocation and death. At the same time, it will also significantly reduce ...
