Embodiment Construction

[0064] Use specific examples to illustrate how to design a complete circulating water system:

[0065] Data collection and basic parameter determination:

[0066] Taking the design of a recirculating aquaculture system for tongue sole as an example, the designed maximum breeding density is 60kg / m 3 , the listing specification is determined to be an average of 1500g per tail. Relevant parameters were entered into the spreadsheet shown in Table 1, and other parameters were automatically calculated.

[0067] According to the biological characteristics of half-smooth tongue sole, the water depth of the breeding pond is designed to be 0.5m. The aquaculture water body of the system can be designed according to the conditions of the construction site, and can also be calculated with the expected output and maximum aquaculture density. In this example, according to the construction site, it is set to 1280m 2 , so the aquaculture water volume of the system is 640m 3 .

Abstract

The invention provides a recirculation aquaculture system design device based on flow control and a recirculation aquaculture system design method based on flow control. Firstly, basic parameters are set according to farmed species, a system total flow is calculated through calculating a farming biological system oxygen consumption amount and according to inlet and outlet water dissolved oxygen concentration, then a mechanical filter parameter is calculated to carry out model selection, a flotation tank volume and efficiency are calculated and model selection is carried out, the parameter of a biological filter is calculated again and the model selection of the biological filter is carried out, a biological filter oxygen consumption amount is obtained according to a total ammonia nitrogen production amount, and an air inflation amount is calculated according to the biological filter oxygen consumption amount. According to the recirculation aquaculture system design device and the method, a circulating water culture system is subjected to modular decomposition, a user can determines the parameter of each module according to breed biological characteristics and local environment characteristics, the method of the design and production of a corresponding module by an industrial enterprise and assembly by the user is used to establish a circulating water culture system, and the operation and maintenance are convenient.

Description

technical field [0001] The invention relates to the technical field of aquaculture engineering, in particular to a flow control-based circulating aquaculture system design device and method. Background technique [0002] The core of recirculating aquaculture is the recirculation aquaculture system (Recirculation aquaculture systems, RAS). RAS is a factory-style aquaculture system that has the function of purifying water for aquaculture and can be recycled. It is characterized by physical, chemical, biological and other methods. Remove or degrade the various metabolic wastes produced in the breeding process and recycle them. RAS is a high-density aquaculture system. Through the separate treatment of aquaculture water by each component of the system, up to 90-99% of the aquaculture water can be recycled, which makes it possible to precisely control the aquaculture environment and water quality parameters, so as to achieve the best Good breeding conditions. [0003] However, ...
