Embodiment 1

[0038] see figure 1 , This embodiment provides an in-situ material recycling device for aquaculture water, which is used in the production process of aquaculture. The recycling device includes a support system, a plant bait cultivation system 3 arranged on the support system, an animal bait cultivation system 4 arranged around the plant bait cultivation system 3, and an underwater lighting system fixedly installed on the support system 5 and the water circulation drive system 6 in the plant bait cultivation system 3 .

[0039] The support system includes a support bracket 1 and a floating ball 2 fixedly mounted on the support bracket 1 . The support bracket 1 is made of stainless steel with an anti-corrosion grade of 316L or above, and the number of float balls 2 is four groups, and the four groups of float balls 2 are evenly arranged around the support bracket 1 . In this embodiment, four groups of floating balls 2 are used as an example for illustration. In other embodimen...

Embodiment 2

[0047] see figure 2 , the present embodiment provides an application method of a recycling device, which is characterized in that it includes the following steps:

[0048] S1 provides an in-situ material recycling device for aquaculture water bodies as described in Example 1.

[0049] S2 In the aquaculture water body, a certain number of recycling and reuse devices are arranged in an array at appropriate intervals.

[0050] The recycling device is slowly immersed into the aquaculture water from the water surface and fixed.

[0051] S3 inoculates the inner layer of the recycling device with plant bait, and inoculates the outer layer with animal bait.

[0052] The inoculum amount of the plant bait is not less than 10% of the volume of the plant layer 33 . Inoculate a sufficient amount of plant bait algae in the inner circle layer, and provide suitable light conditions, and use the metabolic waste of aquaculture organisms to cultivate the plant bait. Inoculate a sufficient a...

Abstract

The invention discloses an aquaculture water body in-situ substance recycling device and application thereof. The recycling device is applied to the aquaculture production process and comprises a supporting system, a plant bait culture system, an animal bait culture system, an underwater lighting system and a water circulation driving system located in the plant bait culture system. The supporting system comprises a supporting bracket and a floating ball fixedly installed on the supporting bracket. The plant bait culture system comprises a supporting frame, an inner ring netting and a plant layer. The animal bait culture system comprises a fixing frame, an outer ring netting and an animal layer. The problems that in the factory-like circulating aquaculture process, a water treatment unit is high in manufacturing cost, additional independent equipment space is needed, and the operation cost is high are solved, a water treatment mode for in-situ cyclic utilization of biogenic substances is established, additional bait is provided, the water quality is improved, and the pressure and load of the water treatment unit are reduced.

Description

technical field [0001] The invention relates to the technical field of water resource utilization and water environment treatment, in particular to an in-situ material recycling device for aquaculture water bodies, as well as an application and an application method of the recycling device. Background technique [0002] At present, the concept of green environmental protection has been deeply rooted in the hearts of the people, and the relevant environmental protection requirements have become more stringent. The relevant aquaculture discharge standards have been implemented, which makes various new technologies such as zero water exchange technology and recirculating aquaculture technology more and more important. In these new aquaculture technologies, various physical, chemical, and biological water treatment units and equipment are usually required to reprocess the water used for aquaculture before it can be recycled. [0003] However, the current water treatment of aquac...
