Preferably, the bottom of the settling chamber is provided with a second drainage assembly 70, the second drainage assembly 70 is a drainage control valve, and the second drainage assembly 70 is connected with the aquaculture body 10. The second drainage assembly 70 is used in cooperation with the timing module, if aerobic denitrifying bacteria in the culture chamber 30 grow poorly due to insufficient nutrient elements, the pH value of the aerobic denitrifying bacteria cannot reach 9.5 all the time, water and carbon source addition need to be replaced every 24 hours, at the moment, the first drainage assembly 60 and the second drainage assembly 70 are both opened, and water in the aquaculture water body 10 needs to be replaced.
Preferably, the output of the water pump 11 is located at 1/3 high in the settling chamber and the second water discharge assembly 70 is attached to the bottom of the settling chamber.
The control system 40 in the denitrification device for aerobic denitrifying bacteria firstly receives the signal feedback of the PH detection component 41, triggering a preset instruction when the pH value of the water body reaches 9.5, opening the first drainage assembly 60 and the second drainage assembly 70, discharging water in the culture chamber 30 and the sedimentation chamber into the aquaculture water body 10, the first and second drain assemblies 60 and 70 are turned off after the water level sensor 42 is triggered after the discharge to a certain extent, and the water pump 11 is opened to start pumping water, the electromagnetic valve 53 is opened to feed the carbon source slow-release ball 51, and finally the PH value is recovered, therefore, the PH detection component 41 and the water level sensor 42 are used as an upper computer to send out instructions, the control system 40 is used as a processor to receive the instructions, and the lower computers such as the first drainage component 60, the second drainage component 70, the water pump 11 and the electromagnetic valve 53 are controlled, and finally the water body in the culture chamber 30 is recovered to be normal, so that a closed-loop control system is formed.
The aerobic denitrifying bacteria denitrification device can be specifically arranged beside a culture pond base, a water body in the culture pond base is pumped and regulated into the culture water body 10, after the aerobic denitrifying bacteria are added into the culture chamber 30 for the first time, the control system 40 is opened to realize intelligent operation, and continuous culture can be realized only by supplementing the carbon source slow-release balls 51 into the storage tank 52. The aerobic denitrifying bacteria in the device grow and reproduce by using nitrogen elements in pond water, the nitrogen elements are converted into gas to be removed, the cultured aerobic denitrifying bacteria are discharged into the culture pond, the water in the culture pond is further denitrified, and the effective control of ammonia nitrogen and nitrite in the water in the culture process is realized.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
