Preferably, aerobic bacteria, facultative bacteria and anaerobic bacteria are cultured on the biological filler 23.
The MBBR reactor 2 used in the invention can repair the biological polluted water body by using a biological carrier and a hydraulics principle. The specific working principle is as follows: the sewage is automatically injected into the container 20 from the water inlet 22 at the bottom of the container 20, the biological filler 23 is suspended in the sewage to be treated in the container 20, and the external air is aerated to the sewage in the container 20 through the air pump 11, the first air inlet pipe 13 and the first aeration member 14.

The plurality of MBBR reactors 2 are divided into two groups on average, one air pump 11 controls the aeration of one group of MBBR reactors 2 and the air-water injection of the first jet pipe 1 through a reversing valve 10, and the other air pump controls the aeration of the other group of MBBR reactors 2 and the air-water injection of the second jet pipe 7 through another electromagnetic valve. The solar panel 12 provides power to the two air pumps.
After being treated by the MBBR reactors 2, the improved water is converged into a water tank 5. referring to FIG. 5, a water outlet 5-1 is formed at one end of the water tank 5, so that the water can only flow out from the direction in which the water outlet is formed, and a pushing force is generated to push the whole device to the opposite direction of the water flow, thereby enabling the whole device to move linearly.
When the device needs to turn, the air pump 11 stops aerating a group of MBBR reactors under the action of the electromagnetic valve 10 to inflate the first jet pipe 1, and the other air pump stops working, so that the first jet pipe 1 jets out unbalanced airflow relative to the device under the action of airflow, and the device is pushed to turn towards one direction. When the device needs to turn towards the other direction, similar operation is adopted, and the other air pump controls the second jet pipe 7 to inflate.
It can be understood that the air control system can be provided with a control chip, and the device can be controlled to automatically move in a large-scale water area through a pre-programmed program so as to automatically realize sewage treatment; the device can also be controlled to move to a designated position by receiving a remote control signal sent by a worker.
With further reference to fig. 6 a-6 c, it can be seen that the mobile in-situ biological wastewater treatment apparatus of the present invention can also be used in combination to form a larger scale overall apparatus, and fig. 6 a-6 c are respectively the case of using two, three and four mobile in-situ biological wastewater treatment apparatuses of the present invention; when the integral device is large enough, the top of the integral device can be decorated to form the ecological floating island.
In conclusion, the movable biological sewage in-situ treatment device provided by the invention has the advantages that sewage is subjected to in-situ treatment by the MBBR reactors, the treated water body flows out from one end of the water tank to provide the thrust of the whole device, the design is ingenious, the aeration and the advancing are coordinated and unified, the complexity and the energy waste of the device are reduced, and the device continuously and slowly moves in a sewage area, so that the sewage in-situ treatment can be effectively realized in a larger water area range.
