The shrimp farming workshop is provided with a temperature control system 150, the temperature control system 150 comprises a fan coil 151 and a temperature sensor 152 which are assembled indoors, the fan coil 151 is used for blowing hot air into the farming workshop, and the temperature in the workshop is ensured to be at a proper temperature.
The shrimp-raising workshop is provided with an automatic high-pressure spray disinfection system 160, the automatic high-pressure spray disinfection system 160 is mainly used for disinfecting the shrimp-raising workshop and removing workshop smell, and the used medicament is mainly potassium permanganate diluted solution or iodophor diluted solution or hydrogen peroxide diluted solution, so that the health growth of shrimps is prevented from being influenced by the visit of external personnel.
A walkway 102 positioned in the peripheral area of the shrimp culture system is arranged in the standardized multi-section shrimp culture workshop, so that the patrol of workers and the walking of visitors are facilitated.
In an alternative embodiment, the standardized multi-stage shrimp farming plant is configured with a first aeration system 110-1 for aerating each of the farming ponds, the first aeration system 110-1 comprising a first main aeration line and a plurality of first branch aeration lines (first aeration lines not shown) each of which opens into each of the farming ponds 110.
In an alternative embodiment, as shown in fig. 4-5, the MBBR reaction tanks 146 include a plurality of small reaction tanks 146-1 which are distributed in a grid shape and are sequentially connected, and the culture water body sequentially flows through each small reaction tank 146-1 for purification, so that the purification effect is greatly improved.

Because the density of the filler is close to that of water, the filler is in a complete mixing state with the water during aeration, and the environment for microorganism growth is in gas, liquid and solid phases. The collision and shearing action of the carrier in the water ensures that air bubbles are finer, and the utilization rate of oxygen is increased. In addition, each carrier has different biological species inside and outside, anaerobic bacteria or facultative bacteria grow inside, aerobic bacteria grow outside, so that each carrier is a micro-reactor, and the nitrification reaction and the denitrification reaction exist simultaneously, thereby improving the treatment effect.
In an alternative embodiment, a manually controlled valve is adopted in the transfer channel, and a plurality of insertion tubes 114 are vertically inserted into and pulled out from one end of the transfer channel connected with the upper culture pond 110 to serve as the valve, and the top ends of the insertion tubes 114 are higher than the liquid level of the upper culture pond 110. When the cultured prawns need to be transferred to the next-stage culture pond, firstly, under the premise of ensuring the emptying of the next-stage culture pond, maintainers pull out the insertion pipe 114 of the current culture pond upwards, and water and the prawns flow to the next-stage culture pond under the action of gravity to continue culture. As the water area of the lower-stage culture pond is increased compared with that of the upper-stage culture pond, the prawns which are increased after growth can obtain more sufficient growth activity space, which is beneficial to the rapid growth of the prawns.
The filter tank 143 is internally provided with a micro-filter, a sedimentation tank 141-1 is arranged between the beam precipitator 141 and the micro-filter tank 143, and solid particles in tail water can be primarily precipitated in the sedimentation tank 141-1, so that the purification pressure of a subsequent purification system can be reduced.
The process for culturing shrimps in the standardized multi-section shrimp culturing workshop provided by the utility model comprises the following steps:
(1) The shrimp larvae are put into the first culture pond 111 for culture, the volume of the shrimp larvae is increased to about 4 times after 45 days, at this time, the space of the first culture pond 111 does not meet the requirement that the shrimp larvae continue to grow sufficiently, at this time, on the premise of ensuring the emptying of the second culture pond 112, the valve between the first culture pond 111 and the second culture pond 112 is opened, water and the shrimp in the first culture pond 111 flow into the second culture pond 112, and as the area of the second culture pond 112 is four times that of the first culture pond 111, the shrimp can obtain a larger movable space.
(2) After the shrimps are cultured in the second culture pond 112 for 45 days, the volume is increased by about 4 times continuously, at the moment, the space of the second culture pond 112 is not enough for the shrimps to continue to grow sufficiently, at the moment, on the premise of ensuring the emptying of the third culture pond 113, the valve between the second culture pond 112 and the third culture pond 113 is opened, and the water and the shrimps in the second culture pond 112 flow into the third culture pond 113, and because the area of the third culture pond 113 is four times that of the second culture pond 112, the shrimps can obtain a larger movable space.
(3) After the shrimp is cultured in the third culture pond 113 for 45 days, the volume is increased by about 4 times, at this time, the shrimp has grown to a size that can be sold, and the shrimp is caught by using a ground cage or a lifting screen.
The above steps are repeated, and after the shrimp water in the upper-stage culture pond is discharged to the lower-stage culture pond, water is injected into the first culture pond 111 and shrimp larvae are thrown into the first culture pond, so that the neutral period of the culture pond is reduced, and the economic benefit is improved.
Since the area of the first culture pond 111 is smaller than that of the second culture pond 112, water injection into the second culture pond 112 is also required for the shrimp water in the first culture pond 111 to be discharged into the second culture pond 112, so as to ensure the water level of the second culture pond 112. And since the third culture pond 113 needs to receive the water and the shrimp discharged from the second culture pond 112 every 45 days, in order to maintain the water level balance, a part of the water of the third culture pond 113 needs to be discharged to the outside before or after the discharge of the second culture pond 112 to maintain the water level balance.
The cultivation water limited by the third cultivation pond 113 can not be directly discharged, so that the MBBR reaction pond 146 matched with the third cultivation pond 113 is further provided with a drainage pipeline, and part of purified water is discharged to the outside, so that the environment-friendly drainage requirement is met.
