Water circulation filtering system for aquiculture

Abstract

The invention relates to a water cycle filtering system for aquiculture, which comprises an ozone treatment system, a mechanical filtration system, a biological filtration system, a liquid-oxygen conversion system and an oxygen saturation system, wherein all systems are communicated through gas pipelines or liquid transport pipelines. In the overall system, the aquaculture water is circularly treated in 24 hours, the aquaculture waste water is treated and then fed into an aquaculture pond again to be used, and the water changing ratio every day is only 3 percent; and the system has the advantages of constant water temperature, good water quality in dynamic water aquaculture, low water consumption in static water aquaculture, and the like. Equipment generates basically enough heat to insulate a fishery so as to save energy; the aquaculture waste is reclaimed for producing organic fertilizer so as to change waste into valuable; the system can achieve zero discharge of the aquiculture, and a water environment achieves pathogen free, waste residue free and pollution free and keeps enough oxygen content of the water body; and the system does not use fishery drugs to cultivate, and is a green, environment-friendly, energy-saving and low-cost aquiculture water treatment system.

Description

【Technical field】 [0001] The invention belongs to the technical field of water treatment and relates to an aquaculture water circulation filter system which is applied in the aquaculture industry and can realize harmless production. 【Background technique】 [0002] Explanation of terms: BIO-BLOK: Biological package, the smallest unit of biological media in biological filters. [0003] Due to the pollution of natural water bodies, the water sources available for cultivation are becoming less and less, and it is becoming more and more difficult to inject water into cultivation. The traditional method of regulating water quality by injecting water is basically impossible to implement, and aquaculture relies more on the self-purification of the biological chain of the pond. However, due to continuous breeding for many years, self-excretion pollution, sediment deposition, pond aging, increase in ammonia nitrogen, hydrogen sulfide, nitrite and other harmful substances, blue and gr...

AI Technical Summary

Problems solved by technology

The output and quality of aquatic products have been seriously affected, and the breeding benefits have declined

[0004] The discharge of feces and sewage from traditional intensive farming has led to serious environmental pollution, resulting in the reduction of beneficial organisms in the water body and the proliferation of harmful organisms. The survival of aquatic food animals such as fish and shrimp is seriously threatened; at the same time, due to water pollution, aquatic food animals Residue and enrichment of toxic and harmful substances, the safety of aquatic food is seriously threatened

[0005] Industrialized aquaculture is a new direction for the development of fishery. At present, the common industrialized aquaculture water treatment systems include sedimentation tanks, aeration tanks, biofilters, filters, disinfection devices, oxygenation equipment and other treatment systems. This system flow Longer, more structures, larger floor space, higher operating costs, and lower water treatment efficiency
