The other end of the hinged connecting rod (10403) is hinged to one side inside the reaction chamber (10103). A floating block (10402) is fixedly installed on the top of the decanter (10401).

9. The intermittent aeration sewage treatment device according to claim 8, characterized in that: The second three-way valve (10405) is fixedly installed on the outside of one end of the sewage discharge assembly (102) provided in the treatment tank (10101), and a connecting pipe (10404) is connected to the bottom of the decanter (10401), and the other ends of the two connecting pipes (10404) are connected to both ends of the second three-way valve (10405), and one side of the second three-way valve (10405) is connected to a drainage interface (10406).

10. A method for using an intermittent aeration sewage treatment device, characterized in that: A sewage treatment device with intermittent aeration as described in claims 1 to 9, comprising the following steps: Step 1, installation: connect the external water pipe to the water inlet interface (10303) and the drainage interface (10406) respectively, so as to facilitate the connection of the sewage to be treated with the device and to facilitate the discharge of the treated sewage, and put the medicine configured according to the type of sewage into the medicine storage hopper (10301) for storage; Step 2, feeding: the first three-way valve (10302) controls the sewage to enter a reaction chamber (10103) to enter the water inlet stage. When the sewage in the reaction chamber (10103) reaches a certain amount, the corresponding quantitative feeding valve (10305) controls a certain amount of medicine to be added into the reaction chamber (10103), and the first three-way valve (10302) controls the sewage to enter another reaction chamber (10103), so that the other reaction chamber (10103) enters the water inlet stage. The air compressor (10501) and the third three-way valve (10502) cooperate to allow the aeration pipe (10503) to expose air to the corresponding reaction chamber (10103) to enter the reaction stage, so that the microorganisms decompose the organic matter in the sewage under aerobic conditions, convert it into carbon dioxide and water, and convert ammonia nitrogen into nitrate through nitrification. Step 3, discharge: After the reaction stage is completed, the aeration component (105) stops aeration and enters the sedimentation stage, allowing the mixed liquid in the reaction chamber (10103) to settle, and the activated sludge settles to the bottom of the concentration bucket (10104), and the supernatant becomes clear. After the sedimentation stage is completed, it enters the drainage stage. The second three-way valve (10405) controls the corresponding connecting pipe (10404) to be connected with the drainage interface (10406) to facilitate the discharge of the treated supernatant inside. The sewage discharge motor (10108) works to move the sewage discharge screw (10107) into the sewage discharge bucket (10202), and the water is compressed during the movement, so that the sludge is dehydrated, concentrated and concentrated in the sewage discharge bucket (10202). The telescopic rod (10205) operates to move the sewage frame (10206) downward, so that the cut-off plate (10207) closes the connecting hole (10203), thereby preventing water inside the reaction chamber (10103) from flowing out of the connecting hole (10203), and enables the sewage hole (10204) to be connected with the sewage outlet (10208), so that the sludge inside the sewage hopper (10202) can be conveniently discharged and processed using tools. After the sludge is discharged, the telescopic rod (10205) operates to move the sewage frame (10206) upward, so that the cut-off plate (10207) opens the connecting hole (10203), and the sealing plate (10209) closes the sewage hole (10204), so that the sludge can be conveniently collected.
