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
The present invention relates to carbonic acid gas and finely ground particles integration removal device in a kind of mariculture, belong to technical field of aquaculture equipment.
Background technology
China has become the first in the world aquaculture big country, accounts for about 70% of world aquaculture total amount.How to change existing aquaculture model, improve cultivation operating automation degree and water treatment efficiency, all will have remarkable impact to the development of the current aquaculture of China.Carbonic acid gas in breeding water body and finely ground particles all can cause larger impact to the existence of water quality and fish, growth.The CO of high concentration
2be harmful to fish body, when exceeding fish tolerance level, significantly can reduce the oxygen carrying capacity of fish body blood, can death by suffocation be caused time serious, also obviously can reduce the pH value of breeding water body simultaneously, affect biological cleaning effect.Research shows, for Tilapia mossambica and perch, and CO
2safe concentration be up to 60mg/L, for responsive fish, CO
2safe concentration be up to 20mg/L.CO in general breeding water body
2concentration requirement be: be less than 10mg/L.In prior art, the general mode of ventilating that adopts removes CO
2, but removal effect is not obvious, and the processing time is long.
Solid particulate matter (SS) in breeding water body is mainly derived from fish faeces, residual bait and fish body deformed limb etc.Result of study shows, its domain size distribution is mainly within the scope of 6.5 ~ 130 μm.Wherein, the particle being less than 100 μm has accounted for the overwhelming majority of particle gross mass; In high-density cultivation system, the molecule proportion of less than 30 μm is then higher, has accounted for 80% ~ 90% of particle total amount in water.The long stop in water body of these solid particulate matters can cause: corrupt decomposition produces ammonia and other noxious products; Blocking wastewater treatment biofilter, the bearing capacity of restriction system; Oxygen is consumed in decomposable process; Directly damage the fish gill, reduce fish growth speed etc.So, how effectively to remove the finely ground particles in marine culture water, very large impact will be had on aquaculture.In prior art, will water to be processed be needed to pass in sieves the oarse-grained solids removing certain content, but the molecule of less than 30 μm cannot be removed, if the screen cloth of sieves is meticulous, easy blockage phenomenon, postpones treatment time of water, reduces water treatment quality.
