Embodiment 1

[0077] see figure 1 , figure 2 as well as image 3 , the present embodiment provides a zero-discharge pond engineering circulating water aquaculture system, the aquaculture system can form a circulatory system, the aquaculture water body can be used repeatedly, and constitutes a small ecological system. Wherein, the breeding system includes a breeding area 31, a sewage collection area 32, a waste collection area 33, a solid-liquid separation device 34, a purification area 35, a filter-feeding area 36, ​​a precipitation area 37, a biochemical area 38, and a purification area 2 39, A central dam 40 and an over dam 41 may also be included. Among them, the breeding area 31 , the sewage collection area 32 , the purification area 1 35 , the filter-feeding area 36 , the sedimentation area 37 , the biochemical area 38 and the purification area 2 39 are set around and form a closed-loop structure.

[0078] The breeding area 31 is used for cultivating various aquatic products, such ...

Embodiment 2

[0096] see Figure 4-7 , this embodiment provides a pond engineered circulating water zero-discharge aquaculture system, which adds an automatic sewage suction device on the basis of embodiment 1. The sewage suction device is used for suctioning sewage in the sewage collecting area 32 in the pond engineering circulating aquaculture system. The sewage suction device can suck out the solid phase particles in the sewage collection area 32, and transport the sewage containing the solid phase particles to the waste collection area 33 of the cultivation system. In this embodiment, the sewage suction device includes a grille 21, a sewage suction cover 22, a water outlet pipe 24, an ultraviolet fluorescent sensor 26, a sewage suction pipe, a sewage suction pump, a driving mechanism and a controller.

[0097] There are multiple grids 21 , and the multiple grids 21 are parallel to each other and arranged at the bottom of the sewage collection area 32 at equal intervals. The plurality ...

Embodiment 3

[0111] see Figure 8 , Figure 9 as well as Figure 10 , this embodiment provides a pond engineered circulating water zero-discharge aquaculture system, which adds a water pushing device on the basis of Embodiment 1. The water pushing device is used to provide a culture area 31 with dissolved oxygen and fluid culture water. The water pushing device can be arranged at the front end of a culture area 31 of a culture system, and deliver the circulating water produced by the culture system to the culture area 31 . Wherein, the water pushing device includes a bottom frame 1 , a side plate 2 , a water baffle 3 , a rear baffle 4 , and an air-lift water assembly, and may also include a top frame 5 .

[0112] The bottom frame 1 mainly plays the role of connection and support for the whole device. It generally adopts a rectangular frame. In this embodiment, it will make corresponding adjustments according to other components. It only needs to ensure that the bottom frame 1 can pass t...

Abstract

The invention discloses a pond engineering circulating water zero-discharge culture system. The culture system comprises a culture area, a sewage collection area, a waste collection area, a solid-liquid separation device, a purification area I, a filter feeding area, a sedimentation area, a biochemical area and a purification area II. The sewage collection area is used for collecting sewage generated in the culture area, and the waste collection area is used for collecting sewage in the sewage collection area and conducting layering; the solid-liquid separation device is used for carrying outsolid-liquid separation on the bottom-layer sewage, and the purification area I is provided with an aquatic plant floating bed I; filter feeding organisms are cultured in the filter feeding area, andthe sedimentation area is used for settling the sewage; the biochemical area is used for receiving supernatant liquor and supernatant liquid and performing aeration treatment on mixed liquid; and thepurification area II is used for purifying and treating the mixed liquid treated by the biochemical area and conveying a purified water body to the culture area. According to the sewage collection area, a flow field in circulating water and a space of an outer pond are reasonably utilized, culture tail water treatment and production are organically combined together, 60%-90% of water body area canbe used for tail water treatment, and large-density culture can be realized.

Description

technical field [0001] The invention relates to a breeding system in the technical field of farming, in particular to a pond engineered circulating water zero-discharge farming system. Background technique [0002] The current recirculating aquaculture system is mainly a recirculation transformation of the traditional flowing water aquaculture system, which has the advantages of simple structure and low cost, but has the disadvantages of limited water quality improvement ability, regular water change, short water use time, and low water treatment effect. Contents of the invention [0003] In order to solve the technical problems that the existing circulating aquaculture system needs to change water regularly, the use time of the water body is short, and the water treatment effect is low, the present invention provides a pond engineered circulating water zero discharge aquaculture system. [0004] The present invention adopts the following technical solutions to realize: a ...
