The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0023] like Figures 1-5 The wastewater treatment filter screen shown includes a support frame 1 and a circular front screen 2 and a rear screen 3 located on top of the support frame. The front screen 2 includes a circular outer ring 4, and a plurality of cross-arranged front partitions 5 are connected to the inner side of the outer ring 4. A plurality of equidistant front screen bars 6 are connected between the plurality of front partitions 5. The rear screen 3 includes a circular outer ring 7, and a plurality of cross-arranged rear partitions 8 are connected to the inner side of the outer ring 7. A plurality of equidistant rear screen bars 9 are connected between the plurality of rear partitions 8.

[0024] Based on the above, the front grille 2 and the rear grille 3 are combined to form a complete filter grille. The entire filter grille is circular and is installed in the waterway of the sewage treatment system, so that half of the filter grille is submerged in the sewage and the other half is suspended in the air.

[0025] A fan-shaped filtration zone 10 is formed between adjacent front spacers 5 and rear spacers 8. A fan-shaped filling component 11 is installed inside the filtration zone 10. The filling component 11 is filled with manganese tetroxide filler. The porous structure and large specific surface area of ​​the manganese tetroxide filler give it a strong adsorption capacity, which can adsorb heavy metal ions, organic pollutants and other impurities in wastewater.

[0026] Several front spacers 5 and several rear spacers 8 are evenly distributed with the same spacing. A recessed limiting groove 12 is provided on the surface of the front spacer 5 near the rear spacer 8, and a raised limiting strip 13 is installed on the surface of the rear spacer 8 near the front spacer 5.

[0027] The limiting strip 13 is embedded in the limiting groove 12 after the front grille 2 and the rear grille 3 are combined.

[0028] Based on the above, the front grille 2 and the rear grille 3 can be separated, and when they are combined together, the limiting strip 13 and the limiting groove 12 can provide a limiting effect.

[0029] The second fastening bolt 24 is inserted at the intersection of the front partitions 5, and the rear end of the second fastening bolt 24 is inserted at the intersection of the rear partitions 8.

[0030] Based on the above, the front grille 2 and the rear grille 3 are combined together, and through the second fastening bolt 24, the front partitions 5 and the rear partitions 8 are fixedly installed.

[0031] The front grille strips 6 are located on the front side of the front partitions 5, the rear grille strips 9 are located on the rear side of the rear partitions 8, and the filtering area 10 is located between the front grille strips 6 and the rear grille strips 9.

[0032] The filtering area 10 is located inside the front grille 2 and the rear grille 3, and the space inside the filtering grille is divided by the front partitions 5 and the rear partitions 8 to form a whole fan-shaped filling part 11 installed inside the filtering area 10 to filter the passing sewage.

[0033] The filling part 11 divides the filtering area 10 into two areas, and a plurality of suspended filler balls 18 are filled in the two areas.

[0034] The suspended filler balls 18 are biological filler balls, and the sewage passing through the filtering area 10 is filtered by the suspended filler balls 18 in addition to being adsorbed by the filling part 11.

[0035] The filling part 11 includes a front baffle 14 and a rear baffle 15, first fastening bolts 16 are installed at the corners of the front baffle 14 and the rear baffle 15 for fixing the two baffles, filling grooves 17 are formed on the inner sides of the front baffle 14 and the rear baffle 15, and manganese tetroxide fillers are located inside the filling grooves 17.

[0036] A filter screen 19 is arranged at the area outside the filling grooves 17 of the front baffle 14 and the rear baffle 15, and positioning holes 20 are formed at the arc-shaped edges of the front baffle 14.

[0037] Based on the above, the manganese tetroxide fillers are filled in the internal space formed by the filling grooves 17 of the front baffle 14 and the rear baffle 15, the internal filling grooves 17 are sealed after the front baffle 14 and the rear baffle 15 are combined together, the two baffles are fixed by the first fastening bolts 16, the filter screen 19 is used for filtering the sewage, and the positioning holes 20 fix the entire filling part 11 on the inner wall of the rear outer ring 7.

[0038] A plurality of positioning plates 21 are fixed on the inner side wall of the rear outer ring 7, and positioning bolts 22 extending into the positioning holes 20 are inserted into the positioning plates 21.

[0039] Based on the above, after the filler groove inside the filling component 11 is loaded with the trimanganese tetroxide filler, the front baffle 14 and the rear baffle 15 are fixedly installed, and then the filling component 11 is attached to the filter area 10 on the inner side of the rear outer ring 7. The positioning bolts 22 are inserted into the gaps between the rear grid bars 9 on the other side of the rear outer ring 7, pass through the positioning plates 21, and are inserted into the positioning holes 20 of the filling component 11, so as to fix the filling component 11 on the inner side of the rear outer ring 7.

[0040] Based on the above, when the filling component 11 is installed, the corresponding suspended filler balls 18 are inserted into the filter area 10 on the inner side of the front grid 2 and the rear grid 3, and then the front grid 2 and the rear grid 3 are combined and fixed by the second fastening bolts 24.

[0041] The driving motor 23 is installed on the top outer wall of the support frame 1, and the output shaft of the driving motor 23 is fixedly connected with the intersection of a plurality of rear partition bars 8.

[0042] Based on the above, when in use, the lower half of the entire filter grid is placed inside the sewage. The driving motor 23 is operated to drive the filter grid to rotate, so that the entire filter grid is continuously turned inside the sewage. The suspended filler balls 18 and the filling component 11 in the filter area 10 on the inner side of the filter grid successively pass through the sewage. The suspended filler balls 18 are continuously in contact with the sewage and the air. After a period of time, a layer of biofilm is attached to the surface of the suspended filler balls 18. When the filter grid is turned into the sewage, the biofilm on the suspended filler balls 18 adsorbs the organic pollutants in the sewage to decompose the organic matter. When the filter grid is turned out of the sewage, the suspended filler balls 18 are in contact with the air to increase the thickness of the biofilm. With the continuous rotation of the filter grid, the sewage is continuously purified and treated.

[0043] Further, in this process, the sewage is filtered by the suspended filler balls 18 and also passes through the filling component 11. The heavy metal ions, organic pollutants and other impurities in the sewage are adsorbed by the trimanganese tetroxide filler through the filter screen 19 and the porous structure and large specific surface area of the trimanganese tetroxide filler. In order to accelerate the penetration rate of the sewage, the filter grid is rotated, so that the filling component 11 is continuously alternately operated in the sewage and the air. After the filling component 11 is moved out of the water surface, the penetration and treatment rate of the sewage in the filling component 11 is accelerated by the action of gravity and centrifugal force, thereby improving the filtration effect of the sewage.
