Description

Water treatment device for seawater recirculating aquaculture

Technical Field

The utility model belongs to the technical field of aquaculture, concretely relates to seawater recirculating aquaculture's water treatment facilities.

Background

Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under artificial control. Generally comprises the whole process of cultivating aquatic products from seedlings under artificial feeding management. The method can also be used for the proliferation of aquatic resources in a broad sense, and aquaculture can be realized by means of rough culture, intensive culture, high-density intensive culture and the like. The rough culture is to put seedlings in medium and small natural waters and to culture aquatic products such as fish in lakes and reservoirs, shellfish in shallow seas and the like by completely relying on natural baits. Intensive culture is to culture aquatic products such as pond fish culture, net cage fish culture, fence culture and the like in a small water body by using bait casting and fertilizing methods. Wherein the large-scale discharge is still the main mode of seawater ponds and industrial aquaculture water in China, the aquaculture tail water contains a large amount of excrement of aquaculture organisms and feed which is not ingested, and the aquaculture tail water is discharged into the environment, thus endangering the surrounding ecology.

In the whole culture process, the key and difficult point of the water product technology is to build good and stable water quality. The aquatic product culture is a pollution process, in the middle and later stages of pond culture, the aquatic products are mainly fed with artificial compound feed, residual baits and excrement of the aquatic products are continuously accumulated, animal and plant corpses are continuously increased, the residual baits, the excrement and the animal and plant corpses are deposited at the bottom of a pond to be subjected to anaerobic decomposition, a large amount of harmful substances are generated, water quality and substrate are spoiled, and the culture environment is deteriorated, and the process is mainly characterized in that: 1. the biological oxidation and decomposition at the bottom of the pool consumes a large amount of oxygen, so that aquatic products are in a low-oxygen environment, and the physique and disease resistance of the aquatic products are reduced; 2. excessive nutrition remains, and a large amount of facultative anaerobes decompose organic substances in a low-oxygen environment to generate a large amount of intermediate products such as ammonia nitrogen, nitrite, hydrogen sulfide, organic acid and the like, so that serious toxic effects on aquatic products are caused; 3. excessive nutrition in the bottom mud is released, so that water eutrophication is caused, meanwhile, trace nutrients such as calcium, magnesium, iron, manganese and the like are deposited on the bottom mud in the form of insoluble salt and are difficult to release due to acidification at the bottom, so that nutrition imbalance is caused, the growth of beneficial algae is inhibited, and the blue algae, dinoflagellate and the like which like abundant nutrition become dominant species, so that the water quality is deteriorated; 4. the environment with low oxygen and high nutrition enables pathogenic bacteria such as vibrio and the like to be rapidly propagated, so that diseases and even death of aquatic products occur. At present, the purpose of regulating and controlling the water quality of aquatic product culture is to reduce organic matters in a water body, and further reduce the biological oxygen consumption and the nutrient balance of a pond. How to adjust the water quality and promote the quick and healthy growth of aquatic products is a problem which always troubles farmers.

The industrial circulating water culture mode is gradually accepted by people and is more and more applied to production practice due to the advantages of environmental friendliness, energy conservation, water conservation and the like. The industrial Recirculating Aquaculture System (RAS) can provide a controllable environment, the size of the system is not limited by environmental conditions, the growth rate of the aquaculture products can be controlled, and even the yield can be predicted. Compared with the traditional culture mode, the circulating water culture production mode can save 90-99% of water consumption and 99% of land occupation per unit yield, and hardly pollutes the environment. Water treatment is the most main part of an industrial circulating water culture mode, water is the environmental condition for survival and growth of aquatic products, and the quality of water quality directly influences the culture yield. At present, the industrial circulating water culture mode is rising in China, the existing water treatment equipment cannot meet the requirements, meanwhile, the labor cost is increased, the industrial culture is high, and people pursue the intellectualization of the culture.
