A dirt storage tank 270 is provided below the lower screen 222.

The filling water treatment device 300 comprises a box body 310, wherein a plurality of treatment tanks 320 are arranged in the box body 310, a treatment tank inlet 330 is arranged above each treatment tank 320, a first stop valve 340 is arranged on each treatment tank inlet 330, and each treatment tank inlet 330 is communicated with the water receiving tank 230. The top of each treatment tank 320 is communicated with each air blowing port 240 through an air blowing pipe 250. The bottom of the box body 310 is provided with an aeration pipeline 350, the aeration pipeline 350 is provided with a plurality of aeration openings 360, and the aeration openings 360 are positioned at the bottom of each treatment tank 320. The bottom of each processing pool 320 is provided with a processing pool outlet 370, and a second stop valve 380 is arranged at the processing pool outlet 370. Each treatment tank 320 is provided with a plurality of fillers 390, the fillers 390 have a porous structure, and the density of the fillers 390 is close to that of water.

Since the density of the filler 390 is close to that of water, the filler is completely mixed with water during aeration, and the environment for microbial growth is three phases of gas, liquid and solid. Each carrier has different biological species inside and outside, anaerobic bacteria or facultative bacteria grow inside, and aerobic bacteria grow outside, so that each filler 390 is a micro-reactor, and nitrification reaction and denitrification reaction exist at the same time, thereby improving the treatment effect. In the reaction process, the filler 390 is in a fluidized state, and further forms suspended-growth activated sludge and attached-growth biomembranes, so that the moving-bed biomembranes use the whole reactor space, the advantages of the attached-phase organisms and the suspended-phase organisms are fully exerted, the advantages and the disadvantages are exploited, and the mutual supplementation is realized. In addition, the collision and shearing action of the filler 390 in water makes air bubbles finer, increasing the utilization rate of oxygen.

The utility model discloses a use method as follows:

the sewage to be treated is introduced into the top of the upper screen 221 from the water inlet 100, and most of the solid impurities are blocked on the surface of the upper screen 221. The water roughly filtered by the upper filter screen 221 enters the water receiving tank 230 by gravity, and flows to each treatment tank inlet 330 through the water receiving tank 230. The time for treating sewage by microorganisms in the filler 390 is required, and water can not enter or exit in the treatment process, so that a plurality of treatment tanks 320 are arranged, and the water in and out of each treatment tank 320 is controlled by using each first stop valve 340 and each second stop valve 380, so that at least one sedimentation tank 410 can be ensured to be capable of entering water at any time, and the continuity of sewage treatment is ensured. When the treatment tank 320 is used for treating sewage, the aeration pipeline 350 provides oxygen for microorganisms by aerating the sewage through the aeration openings 360, and simultaneously disturbs the water flow to increase the contact between the oxygen and the water and between the water and the filler 390. The treated water is discharged through the treatment tank outlet 370, flows into the settling device 400, and is discharged after being settled through the settling tanks 410. The vertical partition plates 440 in the settling tank 410 can divide one settling tank 410 into a plurality of settling spaces, so that the number of settling stages is further increased, and the settling effect is improved. The open design facilitates observation of conditions in the settling tank 410 and the overflow channel 420 and timely discovery of abnormalities. Sludge at the bottom of the settling tank 410 is periodically discharged through the sewage discharge outlet 430.

The roller 210 drives the screen 220 to transmit, the upper screen 221 moves to the lower layer to become the lower screen 222, and the impurities on the surface move to the lower layer along with the screen 220. The gas overflowing from the filler water treatment apparatus 300 is discharged from the gas blowing port 240 through the gas blowing pipe 250, and the gas blowing door 260 is intermittently opened to increase the gas outlet pressure at each time, so that the solid impurities on the lower screen 222 are blown into the dirt storage tank 270. By controlling the opening time of the purge valve 260, the positive pressure in the tank 310 can be controlled, which not only increases the pressure for purging the impurities in the filter net, but also increases the dissolved amount of oxygen in the water in each treatment tank 320.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, and all modifications, equivalents, improvements and the like that are made within the spirit and principles of the present invention should be included in the scope of the present invention.
