[0023] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0024] The following describes the MBBR micro-power sewage treatment devices provided by some embodiments of the present invention in conjunction with the accompanying drawings.

[0025] Example 1:

[0026] Combine Figure 1-4 As shown, the MBBR micro-power sewage treatment device provided by the present invention includes: a sewage treatment tank 100, an adjustment component 200, and a replacement component 300; the sewage treatment tank 100 includes a collection tank 101, an aerobic aeration tank 102, an inclined tube sedimentation tank 103, and a clear water tank 104 therein; the adjustment component 200 includes a water outlet 201 opened on one side of the aerobic aeration tank 102, a filter cartridge 202 movably installed in the water outlet 201, a placement cavity 203 opened on one side of the bottom of the water outlet 201, a brush strip 204 movably installed in the placement cavity 203, and a filter cartridge 202, a main gear 205 fixedly installed on one side of the aerobic aeration tank 102, a sub-gear 206 movably installed in the tank wall on one side of the aerobic aeration tank 102, a fixed plate 207 fixedly installed on the inner end of the sub-gear 206, and a long rod 208 fixedly installed on one side of the fixed plate 207; the outer ends of the main gear 205 and the sub-gear 206 are also meshed with toothed belts 209, the main gear 205 is movably installed in the tank wall on one side of the aerobic aeration tank 102, the outer end of the main gear 205 is also fixedly installed with a motor 210, and a fixing bracket 211 is also fixedly installed between the motor 210 and the outer wall of the aerobic aeration tank 102.

[0027] Specifically, the MBBR micro-powered sewage treatment device is a novel biofilm sewage treatment technology that combines the characteristics of the activated sludge process and the biofilm process. MBBR technology removes organic matter from sewage through the combined action of suspended activated sludge and attached biofilm. In this sewage treatment tank 100, the filter cartridge 202 installed in the water outlet 201 on one side of the aerobic aeration tank 102 can rotate its upper end after residual sludge impurities are adhered to it. During the rotation, the brush strip 204 at the bottom cleans the upper end of the residue, thereby preventing the filter cartridge 202 from clogging and affecting its water output. At the same time, during the rotation of the main gear 205, the toothed belt 209 at the outer end can also drive the sub-gear 206 to rotate, thereby driving the fixed plate 207 and the long rod 208 in the aerobic aeration tank 102 to rotate, thereby slowly stirring the aerobic aeration tank 102 and preventing the filler in the aerobic aeration tank 102 from piling up and adhering to each other.

[0028] Example 2:

[0029] Combine Figure 4 As shown, based on the first embodiment, the replacement component 300 includes a bayonet 301 opened on one side of the brush strip 204, a pressure plate 302 movably installed on the outside of the brush strip 204, and a clamping strip 303 fixedly installed on the inside of the pressure plate 302. Mounting openings 304 are also opened on both sides of the aerobic aeration tank 102. The pressure plate 302 is movably installed in the mounting openings 304. Fixed columns 305 are also fixedly installed in the mounting openings 304. The fixed columns 305 are all movably installed in the pressure plate 302. Springs 306 are also movably installed on the fixed columns 305. The clamping strip 303 matches the bayonet 301.

[0030] Specifically, the pressure plate 302 installed in the mounting port 304 in the aerobic aeration tank 102 can press the brush strip 204 in the placement cavity 203 through the springs 306 at the upper ends of the fixing columns 305 on both sides to ensure stability during use. The brush strip 204 can also be easily disassembled for cleaning or replacement after it is dirty or worn. The clamping strip 303 on one side of the pressure plate 302 is mainly engaged with the inside of the clamping port 301 on the outer side of the brush strip 204 to ensure that the pressure plate 302 firmly presses the brush strip 204.

[0031] The working principle and use process of this utility model:

[0032] When the filler in the aerobic aeration tank 102 accumulates and the filter cartridge 202 in the water outlet 201 becomes dirty, the motor 210 outside the aerobic aeration tank 102 is started to drive the main gear 205 and the filter cartridge 202 to rotate slowly. As the filter cartridge 202 rotates slowly, the brush strip 204 in the cavity 203 at the bottom thereof cleans the impurities and sludge remaining on the outer end thereof, thereby clearing the clogged pores in the filter cartridge 202. As the main gear 205 and the filter cartridge 202 rotate slowly, the toothed belt 209 at the outer end of the main gear 205 synchronously rotates the sub-gear 206, thereby synchronously driving the fixed plate 207 and the long rod 208 at the inner end of the sub-gear 206 to rotate in the aerobic aeration tank 102, thereby slowly stirring the filler accumulated in the aerobic aeration tank 102. At the same time, when the brush strip 204 in the cavity 203 becomes dirty or worn, the pressure plate 302 can be pulled outward to conveniently remove the brush strip 204 for cleaning and replacement.

[0033] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
