The novel sewage filtering system comprises a filtering tank 2, wherein a water inlet pipeline 1 and a water outlet pipeline 10 are respectively connected to the filtering tank 2, a first fixed partition plate 3.1 is arranged in the filtering tank 2, the filtering tank 2 is divided into an upper space and a lower space, and the water inlet pipeline 1 and the water outlet pipeline 10 are respectively communicated with the lower space and the upper space in the filtering tank; the second fixed partition plate 3.2 forms a containing cavity with the top and the bottom respectively opened, the containing cavity penetrates through the first fixed partition plate 3.1 and is communicated with the lower space and the upper space in the filter tank 2, and the bottom of the containing cavity is lower than the bottom of the first fixed partition plate 3.1; the filter device 4 is arranged in the accommodating cavity. The sewage enters the filter tank 2 through the water inlet pipeline 1 and is discharged from the water outlet pipeline 10 through the filter device 4. Since the bottom of the accommodating cavity is lower than the bottom of the first fixed partition plate 3.1, a space for buffering reflux is formed. Under the power effect of rivers, effectively separation sewage produces the back pressure, makes sewage keep chaotic form to can only flow out from the bottom upwards through filter equipment 4, prevent impurity deposit jam, even filtration increases filtration area, improves filtration efficiency.

In this embodiment, the filtering device 4 adopts a multi-layer filtering structure between the upper and lower filter screens 8, the multi-layer filtering structure enables impurities with large and small particle diameters to be sequentially filtered along the water flow direction, and the multi-layer filtering structure is respectively a stone chip layer 6 and a filtering sand layer 7 which are sequentially arranged from bottom to top. The multi-layer filtration can improve the filtration speed, simultaneously prevent that backwash intensity is great or wash water from carrying with a small amount of bubbles and causing the mixed layer phenomenon, can set up filtration filter material class and quantity simultaneously as required, improve filtration efficiency.
