Algae factorization circulating aquaculture system

Abstract

An algae factorization circulating aquaculture system comprises a culture area and a water treatment area. The water treatment area comprises a micro filter tank, a floatation tank, a dark treatment area, a biological treatment area, an ultraviolet sterilization tank, a regulation tank and artificial wetland. The algae factorization circulating aquaculture system is arranged in a light-transmitting steel frame greenhouse or a brick-concrete structure workshop, the culture area is arranged at the central position of the aquaculture system, the water treatment area is arranged around the culture areas so as to fully utilize plane space of the workshop due to surrounding distribution, the whole workshop is compact in distribution, the system can effectively intercept solid particles in culture water and remove ammonia nitrogen in water, high particulate matter concentration water can be collected in a concentration mode and secondarily used through the artificial wetland, environmental pollution and waste caused by direct emission are effectively reduced, culture scale can be large or small, culture facilities are simple, system investment is low, and the system is suitable for individuals or families to perform aquaculture production and is favorable for being popularized and applied.

Description

technical field [0001] The invention relates to the field of industrial aquaculture, in particular to an algae industrial circulating aquaculture system. Background technique [0002] my country is a large aquaculture country and an important supplier of aquatic products in the world. However, the traditional extensive aquaculture method using scale expansion is currently facing enormous pressure from the environment, policy, society and other aspects. Therefore, extensive promotion has the advantages of saving water and saving The land and environment-friendly industrialized recirculating aquaculture system has positive significance. [0003] The industrialized recirculating aquaculture system usually includes two parts: the aquaculture area and the water treatment area. The dissolved oxygen content in the middle and lower layers of the aquaculture area in the aquaculture area is low, and there are usually solid particles such as fish feces and residual bait deposited, so it...

AI Technical Summary

Problems solved by technology

[0005] One is that no light is required in the workshop to provide low-algae or algae-free aquaculture water. At the same time, the aquaculture model is standardized and the equipment is highly integrated. Therefore, the requirements for the site and facilities in the workshop are relatively high, and the operation of the equipment is complicated. Density farming, but it is not in line with the national conditions of my country's current farming industry, which is dominated by individual farming and the scale of farming is uneven;

[0006] The second is the lack of limited interception means for solid particles in the process of water purification, resulting in high solid particle content in aquaculture water, incomplete removal, and unsatisfactory purification effect of aquaculture water;

[0007] The third is that the layout of this breeding mode is mostly left and right. The breeding area and water treatment area are arranged side by side in the breeding workshop, and both are higher than the horizontal floor of the workshop. The processing area and channel area take up a lot of space on the site, the proportion of the workshop area occupied by the breeding area is low, and the utilization rate of the plane space in the workshop is not high;

[0008] Fourth, due to the low algae or no algae in the water body, the content of ammonia nitrogen compounds dissolved in the water body is relatively high, and due to the lack of effective purification means, it is easy to pollute the aquaculture water body;

[0009] Fifth, the aquaculture water body adopts a single-way water cycle mode, that is, the middle water of the aquaculture water body is completed through a water treatment route, and the bottom water is directly discharged regularly, lacking effective purification and recovery methods for the bottom water, which is easy to cause pollution to the environment
