Efficient-sewage-discharging fish breeding system based on sewage-discharging mechanism

Abstract

The invention discloses an efficient-sewage-discharging fish breeding system based on a sewage-discharging mechanism, and solves the problems that fish is bred in stagnant water, so that water is polluted, healthy growth of the fish is affected, time and labor are wasted, the breeding quality is affected when a fishpond is drained, feed is troublesomely fed, and the content of oxygen in the fishpond is low in the prior art. The fish breeding system comprises a fishpond, an anaerobic pool, a rice field, a water storage pool, a first water channel, a second water channel, a third water channel,a fourth water channel, floating aquatic plants, a feed feeding device, a feeding hopper, a feed conveying pipe, an oxygen injection opening, an oxygen injection hose, the sewage-discharging mechanism, a collection device and a sewage-discharging device. According to the system, the fishpond is communicated with the rice field, the anaerobic pool and the water storage pool are arranged between thefishpond and the rice field, the anaerobic pool is used for decomposing algae bodies, residual feed, excrement, fish shells, dead fish and the like, water can be effectively purified, water in the fishpond can flow through the water storage pool at any time, harm to fish bred in stagnant water can be effectively eliminated, fish feed can be conveniently fed, and the content of the oxygen in the fishpond is effectively increased.

Description

technical field [0001] The invention relates to a fish farming system capable of efficiently discharging sewage based on a sewage discharge mechanism. Background technique [0002] In the aquaculture industry, the effect of fish farming is the best. It grows fast, has high value, and has low bait cost. It can be stocked twice a year, and there will be income in that year. Therefore, fish farming occupies an important position in the whole aquaculture industry. With the continuous improvement of fish farming technology, the high-density intensive fish farming model has become the current main farming method. [0003] The water in the existing fish ponds is still water. As the fish grow, the water quality is getting worse and worse, which can easily lead to the death of the fish. Due to the high density of breeding, there will be a lot of pollution during the breeding process. Deposits around the middle outfall on the bottom of the pool. These pollutants include: algae corp...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is: to provide a fish farming system that can discharge sewage efficiently based on the sewage discharge mechanism, and to solve the problem of water quality pollution caused by static water fish culture in the prior art, which is not conducive to the healthy growth of fish, and time-consuming existing in the sewage discharge of fish ponds Laborious, affecting the quality of breeding, troublesome feeding and low oxygen content in fish ponds
