Description

A kind of industrial circulating aquaculture device

technical field

The utility model belongs to the field of aquaculture, and relates to an industrial circulating aquaculture device.

Background technique

Closed circulation water fish farming is an efficient aquaculture method developed in the world in recent years. It makes full use of water resources, improves the utilization rate of resources, reduces the discharge of breeding wastewater into the environment, and prevents environmental pollution. ; At the same time, factory farming has greatly increased production and met residents' demand for high-quality aquatic products.

But as far as the current domestic situation is concerned, it is not optimistic. With the rapid development of the aquaculture industry, aquaculture sewage is discharged without treatment, which gradually reduces the environmental self-purification and regulation capabilities of the aquaculture waters, leading to the deterioration of the water environment. In the feeding-based breeding mode, residual bait, feces, nitrogen, phosphorus and other eutrophication factors are discharged into the water body, so that the chemical oxygen demand (COD) and biological oxygen demand (BOD) in the breeding water seriously exceed the standard. The main cause of water pollution. The products formed by the decomposition of organic matter and nutrients can increase the biological oxygen consumption of the water body, and the accumulation of ammonia nitrogen, nitrite, and nitrate can cause fish poisoning and death and eutrophication of the water body. Therefore, removing or reducing the concentration of ammonia nitrogen and nitrite is an important link to ensure good water quality and reduce environmental pollution. Intensive fish farming uses technologies such as running water, water purification, oxygenation, temperature control, and sterilization to provide a high-density, rapid-growing water environment for fish farming to achieve high output, high efficiency, and low pollution. The circulating water fish farming facilities and equipment built in the country only account for 1.2% of the entire factory fish farming facilities, and a large number of flowing water fish farms and workshops need to be renovated and newly built.

Especially in recent years, the deteriorating environment of fishery waters and the increasing shortage of water resources directly endanger the continuation and development of traditional marine fishing and pond farming methods. Some developed countries in Europe and the United States have restricted the direct discharge of aquaculture wastewater to natural waters. my country sacrifices environmental protection The phenomenon of increasing the consumption of water resources in exchange for aquaculture production is still common.

Industrialized healthy aquaculture of aquatic products has become the main direction of the future development of aquaculture industry. Industrial farming mainly has the advantages of water saving, land saving, and less pollution; strong production controllability, short cycle, high output, and large benefits; high product quality, and pollution-free. However, industrial farming requires a large investment and requires high production technology and management. Therefore, the investment risk is relatively high, which is a practical problem that industrial farming must face. Therefore, the comprehensive utilization of breeding facilities and the improvement of utilization rate, thereby reducing costs and risks accordingly, play an important role in promoting the development of industrial farming.

At present, the domestic drainage system is controlled by plugging pipes and gates, and manual operations are required from time to time to realize the discharge of aquaculture sewage. The process of discharging aquaculture sewage is mostly to manually remove the insertion and extraction pipes for drainage, and sometimes the entire fish pond is required to be emptied, so that a large amount of water is wasted. When the water in the breeding pond is at the height of the external plugging pipe, it will automatically overflow, but the sealing performance of the gate is not very good, basically in a state of continuous water leakage, and part of the breeding water will be wasted.
