Description
Technical field
The present invention relates to a kind of carbonic acid gas (CO
2) removal device, the carbonic acid gas (CO in particularly a kind of water bodys such as the keep-alive system of supporting temporarily that can be applicable to (batch production) high-density fish culture system, marketable fish and the transporting something containerized system of juvenile fish seed in the fishery territory, various fish
2) removal device.
Background technology
The high concentration of carbonic acid gas scientists draws to(for) the research of fish is very harmful for growth and the existence of fish, after surpassing a certain numerical value, its concentration will the toxigenicity effect cause fish death by suffocation, because fish and bacterium can be brought carbonic acid gas in the water body into by respiration and other vital movement, cause that the gas concentration lwevel in the fish blood increases, cause the oxygen carrying capability of fish body blood to reduce, thereby influence the normal activities of fish.
In the Modern Fishery field, the industrial aquaculture dealer is just making great efforts to improve output and reduce making of water resource by the cultivation density that increases fish to be used for reducing energy resource consumption and to reduce environmental pollution, thereby reduces production costs and the raising economic benefit of breeding fish; Similarly, in the fresh and living aquatic products process of circulation, can raise the efficiency and reduce operating cost by the carrying density that increases fish.But; in above-mentioned industrial fish farming; fresh and living aquatic products transportation and fish keep-alive are supported in the process temporarily; because the densification degree of fish is higher; excreta and residual bait that the fish vital movement produces all can produce carbonic acid gas and constantly dissolve in the water body because of biochemical reaction; As time goes on; gas concentration lwevel in the water body can rise to very high; unless method for treating water and reliable device device targetedly; from above-mentioned water body in time and effectively carbonic acid gas is discharged; otherwise will cause the fish toxic reaction, even unnecessary fish kills accident takes place.
In fact in some circulating water culture system, exactly because the gas concentration lwevel in the water body of breeding fish is too high and its alkali effect that disappears makes that pH value decline is too fast, the acid base equilibrium of heavy damage water body has caused the generation of circular water treating system paralysis (for example: biofilter lost efficacy) and fish kill incident.
As the 15～30kg/m of density that breed fish from conventional art
360～100kg/m to modern technologies
3During development, and live fish transportation fish and water ratio is up to 1: 2 when above, people's great majority adopt the pure oxygen method to come oxygen supply, want from breeding water body a large amount of carbonic acid gas to be got rid of fast this moment, traditional aeration process is malfunctioning, therefore, need a kind of carbonic acid gas removal device to realize effective eliminating of carbonic acid gas in the fishery water body especially.
