Abstract
The invention discloses a centralization indoor constant temperature circulation aquaculture system which includes two aquaculture ponds arranged side by side. A water inlet and a water outlet are arranged in each aquaculture pond. An aerator and a swell machine are arranged in each aquaculture pond. The centralization indoor constant temperature circulation aquaculture system is characterized in that the two aquaculture ponds are made of thermal insulation materials. A sewage treatment system is arranged between the two aquaculture ponds. A suction sewage device is arranged at the end of water outputting of each aquaculture pond. The suction sewage device is connected with the sewage treatment system through a sewage pipe. A water outlet of the sewage treatment system communicates with each aquaculture pond. The centralization indoor constant temperature circulation aquaculture system has the advantage that circulation utilization of water for aquaculture is achieved so that the quality of aquaculture aquatic products is improved and pollution of sewage discharges to environment is reduced.
Description
Technical field
The present invention relates to aquaculture system, be specifically related to a kind of centralized constant indoor temperature recirculation system.
Background technology
Traditional aquaculture is all utilize mud ground to excavate culturing pool, and in pond, cultivate various fish, shellfish and shrimps, soil easily becomes sour, and produces mud.The water body in culturing pool can be polluted due to the excreta of the feed for nursing of remnants and fishes and shrimps in breeding process; thus reduce the survival rate of fishes and shrimps; therefore need often to change water; but because this culturing pool is generally more than 5 mu; therefore quantity of exchanged water is large; the not only water of at substantial, the water excreted can pollute river, lake, ocean.Due to change that water can only change the overall water yield at every turn 15% ~ 20%, most aquaculture product is in sub-health state, even if the every per mu yield of the output therefore cultivated reaches more than 1000 jin high yields.Outdoor normal temperature cultivation, makes the cultivation of some local famous brand product be restricted in addition.
Summary of the invention
The object of the present invention is to provide a kind of centralized constant indoor temperature recirculation system, water circulation can be realized and use, improve cultured output, expand breed variety.
To achieve these goals, technical scheme of the present invention is: a kind of centralized constant indoor temperature recirculation system, comprise two culturing pools be arranged side by side be located under constant temperature, this culturing pool is provided with water inlet and water side, aerator and surge machine are set in this culturing pool, these two culturing pools adopt plastic cloth film to surround, it is characterized in that arranging a set of sewage disposal system between two culturing pools, sewage suction device is provided with in the water side of these two culturing pools, this sewage suction device is connected with sewage disposal system by sewage conduct, the delivery port of this sewage disposal system is communicated with culturing pool.This sewage disposal system solid-liquid separating machine, the outlet of solid-liquid separating machine is connected with Protein Separation pond, biofiltration device and ultraviolet sterilization battle array with pumping plant successively and is connected with the water inlet of two culturing pools afterwards.
The present invention adopts HDPE to cultivate special plastic cloth film to carry out native water segregation, prevent seepage, make pool inner water matter not by the impact of culturing pool soil property, due to native water segregation, aquaculture product is breed bacteria not easily, and disease is few, thus reduces antibiotic use, aquaculture product eliminates bilgy odour simultaneously, improves the edible quality of aquatic products.Use aerator that water quality can be allowed to keep containing oxygen condition, cultivation product are increasing gradually the absorptive amount of oxygen in the process of growing up always, thus can reduce the mortality because of anoxic in breeding process of cultivation product.Use surge machine not only can manufacture the spray that cultivation product are liked living, and upper and lower water can be made to replace better, increase the dissolving of oxygen, reduce the several functions such as ammonia nitrogen, nitrous, hydrogen sulphide, the low organic matter in pond and sunlight can also be made to form better photosynthesis, produce the aquatile of fishes and shrimps eating.Dirt at the bottom of pond is discharged with the sewage suction device of current at the bottom of pond, thus protects water body not by secondary pollution.The sewage of discharging from sewage suction device is back in culturing pool after the process of solid-liquid separating machine, protein segregating unit, biofiltration device and ultraviolet sterilization battle array.The mud of discharging from above-mentioned solid-liquid separating machine, protein segregating unit and biofiltration device can make organic manure.Major advantage of the present invention is to realize recycling of breeding water, thus improves the output of aquaculture product, reduces sewage discharge to the pollution of environment simultaneously.Due in constant indoor temperature cultivation, the cultivation of different aquatic products kind can be adapted to, Shortening culturing period.In the present invention, two culturing pools share a set of sewage disposal system, make its highly effective.Through overtesting, adopt recirculation system of the present invention, every per mu yield can reach 20,000 jin, is more than 20 times of traditional aquaculture.
