Embodiment Construction

[0016] In this embodiment, four circulating water containers are taken as an example for illustration, and of course, the quantity in actual implementation can be selected according to the actual situation. The size of each circulating water container can be set as required. In this embodiment, it is 0.8*0.88*1.1m, and the manufacturing material can be stainless steel or fiberglass.

[0017] see figure 1 . From top to bottom, the device is composed of the first circulating water container 1, the second circulating water container 2, the third circulating water container 3, the fourth circulating water container 4 and the mixing container 5 stacked in staggered layers in series through connecting water pipes. The water in the breeding pond A is connected to the cavity of the porous water shower plate 11 in the inner cavity of the first circulating water container 1 located at the highest place through the delivery pipeline A1. Each circulating water container has the same str...

Abstract

The invention relates to a split-level superimposed biological filtration and oxygenation device. The split-level superimposed biological filtration and oxygenation device comprises circulating water containers, as well as porous drip water plates and micro-particle medium layers, which are arranged in cavities of the circulating water containers, and the split-level superimposed biological filtration and oxygenation device is composed of a plurality of the circulating water containers with the same structure which are superimposed and connected in sequence; and a pure oxygen flow area is arranged in the cavity of each circulating water container, the split-level superimposed biological filtration and oxygenation device further has a pure oxygen and water mixed container, and the mixed container is connected in series with all the circulating water containers. The split-level superimposed biological filtration and oxygenation device provided by the invention adopts the plurality of the split-level superimposed circulating water containers, after the pure oxygen flow areas and an automatic cleaning water spray pipe are increased, a certain number of modular circulating water containers can be selected according to requirements of cultivation scale, and when the flow rate of water flow is equivalent, the biological filtration efficiency is doubled; under the action of a tortuous oxygen flow channel formed by a plurality of oxygen diversion plates, pure oxygen and water can be fully mixed and realize contact reaction, and the oxygenation effect becomes very ideal; and the water spray pipe can realize automatic pollution discharge and high time-saving and labor-saving efficiency.

Description

【Technical field】 [0001] The invention relates to a biological filter, in particular to a microparticle spraying type biological filter suitable for application in a circulating aquaculture system, that is, a cross-layer stacked biological filter and oxygenation device. 【technical background】 [0002] With the rapid development of the economy and the improvement of people's living standards, high-density recirculating aquaculture system technology has emerged as the times require. Biological filtration and oxygenation are the key links in the recirculating aquaculture system. Because the efficiency of biological filtration is directly proportional to the effective surface area of ​​the biological carrier, the most efficient biological filter is a suspended sand filter. The effective surface area of ​​a cubic meter of sand can reach 10,000 meters 2 Above, but the biggest disadvantage of the suspended sand filter is the high energy consumption. [0003] In order to overcome...
