Embodiment Construction

[0023] In order to make the technical means, creative features, goals and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0024] Such as figure 1 and figure 2 Shown, a kind of circulating water shrimp culture water treatment method and system, comprise runway type shrimp pond 1, water inlet flow pipe 2, blower aeration flow device 3, flap flow device 4, partition wall 5, Particle filter 6, aerosol biological filter 7, circulating water pump 8, low energy consumption pure oxygen dissolved oxygen device (LHO) 9 and water outlet 10.

[0025] The track-type shrimp pond 1 is rectangular, with a length of 26.4m, a width of 4.4m, an aspect ratio of 6:1, a pond depth of 0.8m, and an effective water body of 70m for shrimp ponds. 3 . The middle part of the shrimp pond is provided with a partition wall 5 with a thickness of 110mm, and the pond wall and the partition wall are made of...

Abstract

The invention relates to a processing method for raising shrimps by circulating water and a system thereof, which is a method for cultivating shrimps by circulating water that outer circulation removes solid particulate matters and alga is combined for purifying water body; the invention also relates to a system for raising shrimps by circulating water, which comprises a runway-shaped shrimp-raising basin, a water flow pushing device and a water treatment system, and the water flow pushing device comprises a reverse turning bed plugflow organ, a blast aeration organ and a shrimp basin inlet plugflow pipe. Under the action of the water flow pushing device, the water body in the basin moves along the runway. At the curve, the sediment grains such as residual bait, dejection of shrimps and the like can be concentrated near the outlet and discharged out of the shrimp basin. In the water treatment system, the processes such as physical filtration, biological filtration and oxygen increasing are adopted for carrying out treatment. In the invention, the methods with low consumption and high efficiency of purifying ammonia and azote by alga, intercepted filtration by a simple gain filter, the combined oxygenation by alga photosynthesis and gas-liquid mixing in the water treatment process are adopted, and the method and system have the advantages of lowering cost, reducing diseases, saving water sources and saving energy and reducing consumption.

Description

technical field [0001] The present invention relates to a water treatment method and system for shrimp farming in circulating water. The present invention particularly relates to a circulating water farming method for shrimps that removes solid particles by external circulation and purifies the water body with algae, and also relates to a shrimp farming system in circulating water. The invention belongs to the technical field of shrimp farming. Background technique [0002] Shrimp farming occupies an important position in the entire aquaculture industry, but its large consumption of water resources and large-scale shrimp diseases caused by exogenous pathogenic microorganisms have become an important factor restricting the development of the industry. [0003] In recent years, many studies have been carried out on shrimp farming models and systems at home and abroad, in order to solve the major technical problems that plague the development of shrimp farming, such as large re...
