White shrimp aquaculture pond with phased pollution discharge and water storage functions and pollution discharge and water storage method implemented by white shrimp aquaculture pond

Abstract

The invention discloses a white shrimp aquaculture pond with phased pollution discharge and water storage functions and a pollution discharge and water storage method implemented by the white shrimp aquaculture pond. The white shrimp aquaculture pond is characterized in that an air blast pipeline is arranged at the bottom of an aquaculture pond body, an inlet of the air blast pipeline is formed inthe outside of the air blast pipeline, and an air blast pump is arranged at the inlet; a pollution discharge pipeline is arranged at the bottom of the aquaculture pond body, a plurality of slit suction ports which are connected with the pollution discharge pipeline are arranged on the pollution discharge pipeline, an outlet of the pollution discharge pipeline is formed in a purified water tank, the purified water tank is arranged on a side of the aquaculture pond body, and a pollution discharge pump is serially connected onto the pollution discharge pipeline; a netted barrel which is coaxialwith the purified water tank is arranged in the purified water tank, a closed end is fixed onto a rotary shaft, the rotary shaft is fixed onto an output shaft of a driving motor by a coupling, a purified water drain pipeline is arranged at the bottom of the purified water tank and is communicated with a supplementary water pipe and a pure water backflow pipe via a three-way valve, and a sludge discharge pipeline is further arranged in the purified water tank. The white shrimp aquaculture pond and the pollution discharge and water storage method have the advantage that the growth speeds of white shrimp can be maintained.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a penaeus shrimp culture pond with periodic sewage discharge and water storage and a sewage discharge and water storage method. Background technique [0002] Penaeus vannamei is one of the three most productive shrimps in the world today. The meat of Penaeus vannamei is delicious, and the processed meat rate can be as high as 67%. It has a wide temperature range and can grow at 18-32°C. , can grow under the condition of salinity 1-40‰, and is an excellent desalinated cultured species. Nowadays, in the process of cultivating Penaeus vannamei, the pool water must be replaced regularly to ensure water quality, and the waste deposited in the culture pond is disposed of. After the dirty water is drained, the silt waste is swept away with a broom, rinsed, and finally injected clean. Therefore, each cleaning and water change needs to be carried out separately, which is time-consumi...
