The baffle is provided with an overflow pipe which is vertically arranged, the lower end of the overflow pipe is communicated with an inner cavity below the baffle, and the upper end of the overflow pipe is positioned above the upper plate surface of the baffle. An upper screen plate and a lower screen plate are sequentially arranged in the tank body below the partition plate from top to bottom, and the periphery of the upper screen plate and the periphery of the lower screen plate are fixedly connected with the inner side wall of the tank body. And a filler is filled in the tank body between the upper screen plate and the lower screen plate. The packing comprises at least 2 packing units, the packing units are tubular, the side walls of the packing units are hollowed out, and a rice-shaped filter frame is horizontally arranged in each packing unit. The filler units are uniformly and tightly filled between the upper screen plate and the lower screen plate; and a water outlet pipe is arranged at the bottom of the tank body.

When the sewage treatment device is used, sewage enters the tank body from the water inlet, under the action of the partition plate, the sewage is in the tank body above the partition plate, the water surface above the partition plate slowly rises along with the increase of the entering sewage, substances with the density higher than that of water in the sewage slowly precipitate on the partition plate, when the water surface rises to the upper end of the overflow pipe, the sewage enters the lower part of the partition plate from the upper end of the overflow pipe through the overflow pipe, and the sewage entering the lower part of the partition plate enters the bottom of the tank body after passing through the upper mesh plate, the filler and the lower mesh plate and then is discharged from the water outlet pipe; when the sewage passes through the filler, large-particle substances with the density smaller than that of the water in the sewage are blocked by the filler, and the filtering is further completed. The sewage treatment tank is precipitated during overflow, so that standing is not needed, sewage can be continuously treated, and the sewage treatment efficiency is greatly improved. Moreover, the filler can be used for removing large-particle substances with density less than that of water, so that the decontamination rate is greatly improved.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in figures 1-4, the sewage treatment tank comprises a tank body 1 which is vertically arranged, and supporting legs 10 are arranged at the bottom of the tank body 1. The top of the tank body 1 is provided with a water inlet 5, the upper part of the inner cavity of the tank body 1 is provided with a horizontally arranged baffle 4, and the periphery of the baffle 4 is matched with the inner side wall of the tank body 1 in a fixed and sealed manner. An overflow pipe 6 is vertically arranged on the partition plate 4, the lower end of the overflow pipe 6 is communicated with an inner cavity below the partition plate 4, and the upper end of the overflow pipe 6 is positioned above the upper plate surface of the partition plate 4. The overflow pipes 6 are four in number and are uniformly arranged along the periphery of the partition plate 4. The lower plate surface of the partition plate 4 is provided with a reinforcing rib 11 shaped like a Chinese character 'jing'. An upper screen plate 7 and a lower screen plate 8 are sequentially arranged in the tank body 1 below the partition plate 4 from top to bottom, and the periphery of the upper screen plate 7 and the periphery of the lower screen plate 8 are fixedly connected with the inner side wall of the tank body 1.
