When gas is generated during the sewage treatment, the sewage treatment tank B102 can automatically move upward under the action of pressure; After the sewage treatment is completed, the staff opens the valve at the bottom of the sewage treatment tank A101, and then rotates the two notched connecting blocks 303 clockwise or counterclockwise ninety degrees to separate the two sealing plates 308 from the two one-way air inlet valves 105. After the two notched connecting blocks 303 are rotated clockwise or counterclockwise ninety degrees, the two connecting plates B108 are inserted into the two notched connecting blocks 303. Then the staff starts the two electric telescopic rods 301. When the two electric telescopic rods 301 are extended, the sewage treatment tank B102 moves upward, and the outside air enters the sewage treatment tank A101 and the sewage treatment tank B102 through the two one-way air inlet valves 105. When the two electric telescopic rods 301 are retracted, the sewage treatment tank B102 moves downward, causing the internal pressure of the sewage treatment tank A101 and the sewage treatment tank B102 to increase, which can speed up the discharge of the treated sewage.
