Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to an aerobic bacteria activated sludge treatment device. Background Art

[0002] Aerobic activated sludge treatment device is a biological treatment system, whose core function is to use aerobic microorganisms to degrade organic matter in sewage. In this system, the aeration tank plays a vital role. As a key structure in the activated sludge sewage treatment process, a large number of aerobic microorganisms are cultivated in the aeration tank. With sufficient oxygen supply, these microorganisms absorb organic matter in sewage and use it as nutrients for their own growth and reproduction, and then purify sewage through synthesis and decomposition. In this metabolic process, aerobic microorganisms not only remove organic pollutants in sewage, but also may undergo nitrification, converting ammonia nitrogen in the water into nitrates, further purifying the water quality.

[0003] However, in the prior art, since the aeration pipes are installed at intervals at the bottom of the aeration tank, only part of the sewage can directly contact with the bubbles, while the sewage above the gaps in the aeration pipes has insufficient contact with the gas, which in turn causes uneven reaction effects of the activated sludge and affects the efficiency of sewage treatment. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an aerobic bacteria activated sludge treatment device.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: an aerobic bacteria activated sludge treatment device, comprising an aeration tank main body, a fixed seat is fixedly connected to the upper edge position of the aeration tank main body, a mounting plate is provided at the upper end of the fixed seat, a top cover is fixedly connected to one side of the mounting plate, a motor is provided at the upper end of the top cover, a rotating shaft is provided at the output end of the motor, the other end of the rotating shaft is fixedly connected to a first gear, a connecting rod is fixedly connected to the lower end of the top cover, a second gear is sleeved on the outside of the connecting rod, a connecting ring is fixedly connected to the lower end of the second gear, a short rod is fixedly connected to the lower end of the connecting ring, and a stirring rod is fixedly connected to the other end of the short rod.

[0006] Preferably, a connecting plate is provided on the left side of the aeration tank body, an aerator is provided on the upper end of the connecting plate, an air inlet pipe is provided on the upper end of the aerator, a connecting pipe is provided at the other end of the air inlet pipe, an aeration pipe is provided on the right side of the connecting pipe, and a water outlet pipe is provided on the right side of the aeration tank body.

[0007] Preferably, a limiting groove is provided on the inner wall of the mounting plate, a rotating groove is provided inside the fixing seat, a support rod is provided inside the rotating groove, a clamping rod is sleeved on the outside of the support rod, a threaded column is provided on the upper end of the clamping rod, a limiting ring is sleeved on the outside of the threaded column, and a fixing ring is fixedly connected to the upper end of the limiting ring.

[0008] Preferably, the first gear is matched with the second gear.

[0009] Preferably, the aeration pipes are in multiple groups and are equidistantly arranged inside the aeration tank body.

[0010] Preferably, the clamping rod is movably connected to the fixing seat via a supporting rod.

[0011] By adopting the above technical solution, by turning on the motor, the motor drives the rotating shaft and the first gear to rotate. With the cooperation of the second gear, the stirring rod rotates with the second gear, thereby stirring the sewage in the aeration tank body. The setting of multiple sets of stirring rods can further increase the mixing effect. The stirring rod can be rotated in the aeration tank through the motor, the first gear, the second gear, the connecting ring, the short rod, etc., thereby ensuring that the activated sludge in the pool water can fully contact the gas generated by the aerator, thereby improving the reaction efficiency of the activated sludge, and also improving the efficiency of sewage treatment.

[0012] By adopting the above technical solution, by rotating the fixing ring, the internal thread of the fixing ring cooperates with the external thread of the threaded column, the limiting ring moves away from the mounting plate, and the clamping rod can be rotated out of the limiting groove, thereby realizing the separation of the mounting plate and the fixing seat, that is, completing the disassembly of the top cover. Similarly, during installation, it is only necessary to press the bottom of the mounting plate against the fixing seat and rotate the clamping rod and the fixing ring. The clamping rod will rotate outside the support rod into the limiting groove, and the limiting ring and the fixing ring will fix the mounting plate to complete the installation of the top cover. The top cover can be easily installed and removed through the fixing seat, support rod, clamping rod, threaded column, limiting ring, fixing ring, etc., which is convenient for repair when the motor, gear or stirring rod fails, and also simplifies the maintenance process.
