This invention discloses a reactor for the remediation of carbon and nitrogen metabolism in lake water under low-oxygen conditions. When the riser pipe is filled with water, the water tank, riser pipe, and drain pipe can form a siphon effect. Through the sludge suction port, sludge from the bottom of the reaction chamber is first pumped into the water tank, then raised to the top of the riser pipe, and finally discharged out of the water tank through the drain pipe. The siphon effect can enhance the suction force of the sludge suction port. When the siphon is started, the air-sealing ring first descends to close the air inlet, and then the piston rises. At this time, the one-way diaphragm closes. As the piston rises, the water in the water tank is pushed into the riser pipe by the piston, thereby expelling the air in the riser pipe from the drain pipe, thus starting the siphon. When the piston descends, the one-way diaphragm opens upward to prevent the piston's descent from interfering with the siphon process. When the siphon is stopped, the air-sealing ring rises to allow air to enter the riser pipe, thereby breaking the siphon. Through the cooperation of the air-sealing ring and the piston, the siphon effect can be automatically started and stopped, facilitating the control of the cleaning work.
