The high-density temporary culture water treatment equipment for the living bodies of the freshwater aquatic products aims at the high-density temporary culture freshwater, and the freshwater is generally transported along with the living bodies of the freshwater aquatic products and can also be added after reaching a transportation destination. The living bodies of the fresh water aquatic products in the temporary culture pond can be fishes, shrimps, crabs, shellfishes and the like, and a large amount of excrement, mucus and other substances can be discharged under the condition of high-density temporary culture. Without a water treatment system, the water quality becomes rapidly turbid and the dissolved oxygen concentration in the water decreases rapidly. Meanwhile, under the decomposition of the organic matters by bacteria, a large amount of harmful substances such as ammonia and nitrite are generated, so that the capability of the living blood of the freshwater aquatic products for carrying oxygen is reduced, and the living bodies of the freshwater aquatic products die due to oxygen deficiency. The living bodies of the freshwater aquatic products are temporarily cultured for a long time by using the temporary culture pond for the living bodies of the freshwater aquatic products, so that the living bodies of the freshwater aquatic products keep alive for a long time, and the sale of merchants is facilitated. In order to eliminate the hidden troubles by using simple equipment, the equipment adopts a two-way circulation mode to comprehensively treat water.
In the first way, the water is pressurized by the water pump, when the water pressurized by the water pump passes through the filter, solid particles, partial mucus and the like in the water are blocked by the filter, the filter is subjected to backwashing operation after a period of time, filter residues are discharged and separated from the whole temporary culture water body, so that the filter residues are prevented from being changed into soluble substances such as nitrite, ammonia, hydrogen sulfide and the like under the decomposition action of bacteria, and the load of subsequent equipment can be reduced. Filtered water enters the automatic constant-temperature refrigerating machine through the pipeline, the automatic constant-temperature refrigerating device can reduce the water temperature, and after long-time circulation, the automatic constant-temperature refrigerating machine stops running after the water of the whole device is reduced to the target temperature, so that the living body survival state of the fresh water aquatic products can be kept.
The second path of circulating water is treated by the ultramicro bubble generating device and the ozone generator, ozone generated by the ozone generator enters from an air inlet of the ultramicro bubble generating device, water passes through the ultramicro bubble generating device and is fully mixed with the entering ozone to form a large number of ultramicro bubbles with the diameter smaller than 0.1mm, the total contact area of the ozone and the water is greatly increased, the concentration of the ozone in the water is improved, the oxygen content in the water is further improved, the ultramicro bubble generating device mainly plays a role in mixing the water and the ozone, an additional gas dissolving device is not needed, and the cost is saved.
The ozone has strong oxidizing property, and can make the protein on the surface of the microorganism such as bacteria, viruses and the like lose activity, so that the ozone can quickly and thoroughly kill most of pathogenic microorganisms such as bacteria, viruses and the like, and can effectively prevent aquatic products in the temporary rearing pond from dying due to wound infection. Ozone dissolved in water can react with some soluble toxic substances, part of ammonia is contained in the excrement of seafood, and part of organic excrement can be decomposed into nitrite, and the substances can generate fatal toxicity to the living bodies of aquatic products. The ozone can oxidize the harmful substances to generate substances, such as nitrate, which are non-toxic to the live seafood, and can effectively reduce the risk of poisoning and death of the live seafood due to the accumulation of the harmful substances. Chemical Oxygen Demand (COD) refers to the amount of oxygen consumed by the chemical oxidation of the oxidizable substances in the water. Ozone reduces COD in water and reduces the probability of oxygen deficiency death of living aquatic products caused by overhigh COD. Meanwhile, the water quality of temporary culture can be clear, and the appearance of customers in selecting the living aquatic products is facilitated. The residual ozone can be rapidly decomposed in water, and the only product after decomposition is pure oxygen, so that the dissolved oxygen degree in water can be further increased.
After the device operates for more than 2 hours, the water in the temporary culture pond is taken for detection, the turbidity of the water is less than 2, the total amount of suspended matters is 60mg/L, the dissolved oxygen reaches 8.5ppm, the ammonia nitrogen content is 0.05ppm, and the nitrite is detected to be 0ppm, which all accord with the national fishery water quality standard.
As described above, the present invention can be realized well, and the above embodiments are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention; all equivalent changes and modifications made according to the present invention are intended to be covered by the scope of the claims of the present invention.
