Description

Technical Field

[0001] The utility model relates to a micro air flotation generator for sewage treatment, belonging to the technical field of sewage treatment equipment. Background Art

[0002] Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, catering, etc., and is increasingly entering the daily lives of ordinary people. Micro flotation generators are used in the sewage treatment process. Flotation machines have good effects in treating industrial wastewater, domestic sewage, etc., and can effectively remove suspended matter, oil and other impurities in the water.

[0003] According to the announcement number CN220131935U, a micro-flotation generator for sewage treatment is provided, including a box body, a pump body is arranged at the upper end of the box body, a support tube is arranged below the pump body, a branch bracket is arranged at the lower part of the support tube, and a microporous exhaust port is arranged at the upper part of the branch bracket, wherein a connecting pipe is arranged in the middle of the support tube and the branch bracket, and the external gas is pressurized by the pump body and then discharged through the connecting pipe through the microporous exhaust port. A plurality of groups of liquid discharge ports are arranged on the right side of the box body. The utility model introduces sewage to be treated into a box body through a water inlet, pressurizes external gas through a pump body, and discharges micro-nano bubbles through a connecting pipe and a microporous exhaust port, observes the liquid level in the water through a liquid level detector, and controls the switch of the discharge port through a controller. The corresponding controller can be selected according to the liquid level of the treated sewage in the box body to open the discharge port to discharge the sewage. When the above device is in use, more discharge ports are set for selection and use, but the heights of the discharge ports are fixed. Therefore, when discharging sewage, it is easy for the discharge port to be higher or lower than the liquid level of the impurities, thereby failing to effectively ensure that the impurities are discharged, making the applicability of the device low.
