Background technique

With the increasing development and utilization of environmental resources by human beings, industrial development and the high concentration of urban population, a large amount of industrial wastewater and domestic sewage generated in production and life are discharged into river water bodies, making the concentration of nitrogen, phosphorus and organic oxygen-depleting substances in water bodies The rise of the water body has exceeded the production capacity of the water body itself, making the water body continuously enriched with a large amount of nutrients, causing the phenomenon of eutrophication of the water body to intensify. Under these conditions, blue-green algae will grow wildly, and eventually cover the entire water area, resulting in serious algal blooms. When an algae bloom breaks out, the dominant algal species proliferate abnormally, which increases the viscosity of the water body, which not only consumes dissolved oxygen in the water body, but also produces toxic substances, which are harmful to human health, water ecosystems, aquatic animals and plants, and water landscapes. big influence.

At present, my country's control measures for algae blooms are still mainly based on governance, that is, countermeasures are generally taken after the outbreak of algae blooms. The commonly used methods mainly include physical, chemical and biological methods. The physical method is to remove algae by manual salvage, machinery or sediment dredging, which is not only time-consuming and labor-intensive, but also cannot fundamentally solve the problem; the chemical method mainly removes algae in the water by injecting chemicals or coagulants, but The result is that chemical agents cause poisonous effects on aquatic animals and plants, resulting in secondary pollution; biological methods mainly include algae removal of aquatic plants and aquatic animals. Among aquatic animals, silver carp and bighead carp are two common domestic fishes, which are relatively easy to obtain; both of these two fishes feed on phytoplankton and have strong survival ability. They can feed on the poisonous Microcystis algae, have strong resistance to the toxins secreted by the algae, and grow fast and consume a large amount of food. They are considered to be used to control cyanobacteria blooms.

Using this method to inhibit the growth of algae has the advantages of high efficiency, no pollution, and safety. But, in the process of transportation, conditions such as the stress response of fish such as silver carp and bighead carp (collision in transportation process as impatient silver carp), water quality and water temperature seriously affect its survival rate. If no measures are taken, under normal circumstances, the survival rate of silver carp during transportation is only 50%; when there is interference from external factors, the survival rate will be even lower.

Therefore, new technologies and equipment are needed for the transport of live fish such as silver carp.

The following silver carp is an example to illustrate how to utilize the system of the present invention to carry out transportation work.

According to the ratio of primary water: target water=1:1～3:1 (volume ratio), the water body is put into the box body 2, and the silver carp to be transported is put into the fishing net 17 with a side length of 1～3mm pores, and the The water in the box is then added with a concentration of 15-25mg/L and a ratio of vitamin C: MS-222 anesthetic = 1:3-3:1 (mass ratio), and mix well. In the process of transportation, open the water circulation and temperature control system and the dissolved oxygen system, the oxygen bottle 10 controls the flow and the flow rate of the oxygen through the oxygen delivery control valve 13 according to the data of the dissolved oxygen sensor 14, and prevents the silver carp from dying due to lack of oxygen in the water. During the water circulation process, the dirty water at the water outlet 3 is converted into usable water entering the tank 2 through the water circulation system 7, and the temperature of the water body is regulated by the water temperature regulator 8 to meet the temperature requirements of silver carp during transportation. Illumination lamp 9 is opened all the time, avoids silver carp to cause death of stress reaction because of light. After transporting to the water area where algae removal is required, put the mesh bag and silver carp into the water body together. After the algae removal effect reaches the expected effect, it can continue to be placed in the box to replace the water body and continue to use.
