[0003] When we treat sewage, we form micro-bubbles in the sewage in the reaction tank by a specific way, so that the micro-bubbles are adsorbed on the suspended particles to form dross. Since the density of the bubbles is much smaller than that of water, the overall density of the dross after adsorbing the suspended particles will decrease, and the dross will be affected by the water buoyancy, so it will float up and eventually float on the top of the sewage. The liquid after sewage treatment is below the dross, which is separated from the suspended particles, achieving the effect of solid-liquid separation. Then, the dross is treated, and the dross floating on the water surface is scraped and collected into a sludge tank using a slag scraping plate, and finally the dross is destroyed.

[0043] In this embodiment, the reason for such arrangement is that the cleaning of the slag scraping plate 3 needs water source, and the water source can be selected as the water source after the solid-liquid separation in the reaction tank 2 without unnecessary waste of water source, the water source in the reaction tank 2 is extracted and used for flushing the slag scraping plate 3;

[0044] Considering that the slag scraping plate 3 is repeatedly driven to move above the reaction tank 2 during work, the position of the slag scraping plate 3 is not fixed, when the slag scraping plate is driven between the two flushing assemblies, the two flushing assemblies can flush the two sides of the slag scraping plate, so that the slag scraping plate 3 can be flushed overall, therefore the flushing assembly is arranged above the slag scraping mechanism, and considering that if only one flushing assembly is used for flushing when the flushing assembly flushes the slag scraping plate 3, only one side of the slag scraping plate 3 can be flushed, so that the slag scraping plate 3 still has floating slag attached thereto after passing through the flushing of the flushing assembly, therefore two flushing assemblies are symmetrically arranged above the slag scraping mechanism, the other end of the water supply pipe 5 is communicated with two flexible hoses 6, the two flushing assemblies are respectively communicated with the two flexible hoses 6, and are used for synchronously flushing the two sides of the slag scraping plate 3 when each slag scraping plate 3 moves to the upper position and is located between the two flushing assemblies, the flushing assembly comprises a water collecting pipe 101 and a flushing nozzle 104, the two water collecting pipes 101 are respectively communicated with the two flexible hoses 6, the top end of the reaction tank 2 is fixedly connected with a waterproof cover 102, and both ends of the water collecting pipe 101 are fixedly connected with a rotating shaft 103, the rotating shaft 103 is rotatably installed on the waterproof cover 102, the flushing nozzle 104, a plurality of flushing nozzles 104 are communicated on the water collecting pipe 101, and the flushing direction of the flushing nozzle 104 is downward;

[0046] In consideration of the fact that most of the scum on the scum baffle 3 has been washed away after the scum baffle 3 has moved to the upper position and been washed by the washing assembly between the two washing assemblies, but some impurities may still remain on the scum baffle 3 and may still be adsorbed on the scum baffle 3, the device further comprises a brushing assembly for brushing the scum baffle 3 that has been washed, the brushing assembly comprising a water guide pipe 301, brushing nozzles 302, a connecting plate 303 and brushes 304, one end of the water guide pipe 301 being in communication with the water supply pipe 5, the other end of the water guide pipe 301 being in communication with a plurality of brushing nozzles 302, the washing direction of the brushing nozzles 302 being vertically downward, the connecting plate 303 being detachably connected to the waterproof cover 102, a plurality of brushes 304 being fixedly connected to the connecting plate 303, the brushing nozzles 302 being directly above the brushes 304;

[0047] In consideration of the fact that the water source for washing the scum baffle 3 and the brushes 304 by the water pump 4 should be as clean as possible, if the water source still contains too many impurities, the scum baffle 3 and the brushes 304 may still have impurities after being washed, the device further comprises a filtering assembly for filtering the water source drawn from the reaction tank 2, the filtering assembly comprising a filtering pipe 401, a circular filter screen 404 and a stop ring 405, the water guide pipe comprising a first water guide pipe section 402 and a second water guide pipe section 403, the lower end of the filtering pipe 401 being detachably in communication with the first water guide pipe section 402, the upper end of the filtering pipe 401 being detachably in communication with the second water guide pipe section 403, the circular filter screen 404 being arranged in the filtering pipe 401, the diameter of the circular filter screen 404 being the same as the inner diameter of the filtering pipe 401, and the diameter of the circular filter screen 404 being greater than the inner diameters of the first water guide pipe section 402 and the second water guide pipe section 403, the stop ring 405 being fixedly connected to the inner wall of the filtering pipe 401 for limiting the position of the circular filter screen 404 in the filtering pipe 401, so that the circular filter screen 404 is always at the top of the filtering pipe 401;
