Technical Field

The invention relates to a system for symbiosis of shrimps and rice.

Background

The pond shrimp culture is a shrimp culture mode used in most areas in China, has a large proportion of fresh water shrimp culture, and has the characteristics of small investment, large income, quick response, stable production and the like.

Traditional pond shrimp culture causes water pollution because of throwing in fodder, fertilizer, and a large amount of organic matters deposit at the bottom of the pond, takes place shrimp disease very easily, and these sewage do not add purification treatment direct discharge, more can cause the pollution of environment. However, most of the shrimp-culturing farmers in the pond do not have enough funds to purchase equipment for purifying and treating a large amount of generated sewage, and the phenomenon of disordered sewage discharge occurs.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: provides a system for symbiosis of shrimp and rice, which solves the problem of environmental pollution caused by direct discharge of sewage in a shrimp pond in the prior art.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows:

a system for symbiosis of shrimps and rice comprises a shrimp culture pond connected with a drain pipe, a rice field and annular purification channels distributed around the rice field, wherein the annular purification channels are communicated with the free end of the drain pipe; the bottom relief of shrimp culture pond is the wave, shrimp culture pond bottom is being located the wave median line department in crosscut bottom and is being equipped with main sewage disposal passageway, the one end of main sewage disposal passageway extends to one side pool wall of shrimp culture pond, its other end is followed another lateral wall of shrimp culture pond is worn out and with the blow off pipe connection, the bottom of shrimp culture pond is being located bottom wave shape each trough department and is being equipped with branch sewage disposal passageway, all divide sewage disposal passageway all with main sewage disposal passageway intercommunication, each divide sewage disposal passageway's top surface all to set up the sewage manhole that a plurality of equidistance distributes.

Further, the purifying filler is a plastic filler.

Furthermore, a water gate is arranged on the sewage discharge pipe.

Furthermore, a water supply pump is arranged on the water supply pipe.

Compared with the prior art, the invention has the following beneficial effects:

the device has the advantages of simple structure, scientific and reasonable design, convenient use, conservation of field due to symbiosis of shrimps and rice, convenient culture and supplement of biological bacterial colonies, and improvement of purification effect by more than 30%.

The shrimp culture pond can better discharge harmful substances in time and prevent the accumulation of the harmful substances, thereby reducing the morbidity of the shrimps and improving the yield of the shrimps.
