Technical Field

[0002] With the continuous development of society and industrialization, people's demand for energy has increased significantly. In recent years, the overexploitation and consumption of fossil energy has not only caused an energy crisis, but also brought serious environmental pollution problems. Therefore, all fields need to carry out in-depth technological innovations for energy conservation and carbon reduction. With the improvement of living standards, the discharge of urban domestic sewage has also shown a gradual increase. Sewage contains a large amount of organic pollutants. If it is discharged into natural water bodies without proper treatment, it will seriously damage the water ecological environment and cause water quality deterioration.

[0003] According to a sewage treatment device disclosed (publication number: CN 111268822A), it includes a mounting foot, a counter-sedimentation mechanism, a grease diversion mechanism and a sludge clearing mechanism; the right part of the top of the mounting foot is welded to the counter-sedimentation mechanism; the left part of the top of the mounting foot is connected to the sludge clearing mechanism, and the right part of the sludge clearing mechanism is connected to the counter-sedimentation mechanism; a grease diversion mechanism is arranged on the top of the counter-sedimentation mechanism. The present invention achieves the effect of separating the floating grease and sewage in the sewage and treating the sewage separately, while improving the kinetic energy of molecular motion, increasing the molecular collision rate, achieving flocculation, improving the kinetic energy of molecular motion, causing the crystal nuclei to aggregate, achieving the sedimentation effect, separating the settled sludge from the clean water, and improving the effect of sewage discharge purification treatment.

[0004] In the above application, the organic matter in the sewage cannot be degraded by microorganisms in an anaerobic environment through the mutual cooperation between the hedging sedimentation mechanism and the grease diversion mechanism components, and the generated biogas cannot be collected, resulting in a waste of resources and unsatisfactory results. Summary of the invention

Through the mutual cooperation between the components such as the motor, the collection box, the rotating shaft, the semi-circular disc and the air inlet inside the collection device, when the motor is started, the rotating shaft rotates, so that the semi-circular disc intermittently opens the air inlet. When the air inlet is opened, the biogas generated by the organic matter in the sewage under the anaerobic environment enters the collection box through the air inlet. The biogas concentration in the collection box is detected by detecting the gas, thereby achieving the effect of gas collection and solving the existing problems.

[0041] A specific application of this embodiment is: when it is necessary to perform anaerobically treatment on sewage, first pass the sewage through the pretreatment device, filter the sewage first, and then start the first electric telescopic rod 61. When the first electric telescopic rod 61 is started, the telescopic end of the first electric telescopic rod 61 pushes the slider 66 to connect the first water port 67 on the slider 66 with the connecting pipe 64. When the first water port 67 is connected with the connecting pipe 64, the sewage in the pretreatment box 3 enters the anaerobic box 5 through the connecting pipe 64.

When the shaft 73 rotates counterclockwise, the semi-disc 74 on the shaft 73 opens the air inlet 75. When the air inlet 75 is opened, the biogas enters the collection box 72 through the air inlet 75. After the treatment is completed, the sewage needs to be discharged. First, the leak-proof cover 85 is removed, and then the second electric telescopic rod 81 is started. When the second electric telescopic rod 81 is started, the telescopic end of the second electric telescopic rod 81 pushes the baffle 83, so that the second water port 86 on the baffle 83 is connected with the water outlet 63. When the second water port 86 is connected with the water outlet 63, the water in the anaerobic box 5 is discharged through the water outlet 63.
