[0020] like Figure 1 As shown, the upper left position of the primary filter 1 is connected with a liquid inlet pipe 21, and the primary filter 1 and the first treatment tank 2 are connected through the guide port 3. After the tail water first enters the interior of the primary filter 1 for pre-filtration treatment, the tail water after the primary filtration will be gradually sent into the interior of the first treatment tank 2 through the guide port 3; a second treatment tank 18 is provided on the side of the first treatment tank 2 away from the primary filter 1, and a third treatment tank 19 is provided on the side of the second treatment tank 18 away from the first treatment tank 2, and a liquid outlet pipe 20 is connected to the upper position of one side of the third treatment tank 19. By respectively arranging the first treatment tank 2, the second treatment tank 18 and the third treatment tank 19, this arrangement will make the entire device a specific multi-stage treatment structure, thereby being able to better treat the tail water.
[0021] like Figure 1 , Figure 2 and Figure 3 As shown, a mixing motor 16 is fixedly installed at the middle position of the top of the first treatment tank 2, and the output end of the mixing motor 16 extends to the inside of the first treatment tank 2. A stirring support rod 17 is arranged outside the output end of the mixing motor 16. The stirring support rod 17 is arranged inside the first treatment tank 2. After the acid solution or alkaline solution and hot water or cold water are respectively injected into the inside of the first treatment tank 2, the device will quickly stir and mix the mixed liquid together through the force generated by the mixing motor 16 and the stirring support rod 17 rotating; the speed control box 4 is provided with a conveying inner cavity 8, and the shape of the conveying inner cavity 8 is "L "-shaped structure is set, the liquid outlet end of the conveying inner cavity 8 and the interior of the first treatment tank 2 are connected, a movable valve core 9 is provided at one side of the horizontal end of the conveying inner cavity 8, one end of the movable valve core 9 is connected to a telescopic rod 10, the telescopic rod 10 is arranged inside the speed control box 4, the acid solution box 13 and the alkaline solution box 14 are respectively arranged at the upper left of the top surface of the first treatment tank 2, when the tail water enters the speed control box 4 through the inlet side opening 5, the device will use the blocking effect of the movable valve core 9 on the conveying inner cavity 8 to control the flow of the tail water that is about to flow into the first treatment tank 2.
[0022] Working process: The electric energy required for the startup and operation of the device in the utility model comes from an external power supply, and the multiple electromagnetic valve bodies that respectively control the hot water injection pipe 11, the cold water injection pipe 12 and a group of guide pipes 15 are respectively connected to the tail water treatment control system. When the aquaculture tail water treatment device is needed, the aquaculture tail water first enters the interior of the primary filter 1 through the interior of the liquid inlet pipe 21 to be filtered and screened. The aquaculture tail water after screening will first enter the inlet side opening 5 through the guide port 3, so that the device can detect the water temperature and pH value of the aquaculture tail water through the temperature sensor 6 and the pH sensor 7.
