[0002] In the early days of sewage treatment, people tended to use manual filtration methods to remove suspended solids and particulate matter from sewage. Workers would manually filter sewage with fine mesh or fabric, which was inefficient and not effective enough. With the development of industrialization, the need for sewage treatment became more urgent. Single-layer fixed filter plates came into being. These filter plates are usually made of metal or plastic materials and are installed on a fixed support structure to filter and intercept suspended solids and solid particles in sewage. However, due to the limitations of the single-layer design, its filtration capacity and effect are still limited.

[0003] Most of the existing filter frames are single-layer filters and can only filter one type of debris at a time, so the existing filter frames need to filter sewage multiple times; when cleaning the existing filter frames, the filter plates need to be taken out for cleaning, and the filter frames cannot work during the cleaning process; therefore, the above problems need to be improved.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0018] Embodiment: Refer to Figure 1-4 , a filter frame plate for sewage treatment in the present utility model includes a box body 1, and is characterized in that: a plurality of holes are evenly opened on the upper and lower end faces of the box body 1, facilitating the entry and discharge of water through the holes; baffles 2 are installed on the front and rear faces of the box body 1 to prevent the water entering the box body 1 from leaking out; vertical fixing seats 3 are fixedly connected to the front and rear ends on both sides of the bottom surface of the box body 1, and horizontal fixing seats 4 are fixedly connected to the front and rear ends on both sides of the top surface of the box body 1. The box body 1 is fixed by the internal threaded pipes of the vertical fixing seats 3 and the horizontal fixing seats 4; and threaded holes are opened on the side surface of the vertical fixing seat 3 and the upper end surface of the horizontal fixing seat 4, and a filtering component is arranged inside the box body 1. The filtering component includes a first filter plate 5 arranged inside the top of the box body 1, a second filter plate 6 arranged above the middle of the box body 1, a third filter plate 7 arranged below the middle of the box body 1, and a fourth filter plate 8 arranged inside the lower part of the box body 1. The sewage is filtered four times by the four filter plates; and gauze layers 9 are arranged on the top surfaces of the first filter plate 5, the second filter plate 6, the third filter plate 7, and the fourth filter plate 8 to hold the filter elements inside the filter plates through the gauze layers 9. A rectangular frame is fixedly connected to the inner end surface of the baffle 2, and rectangular grooves 10 matching the rectangular frames on the baffle 2 are opened on the front and rear faces of the box body 1. The baffle 2 is fixed on the box body 1 through the rectangular frame and the rectangular groove 10.

[0019] In the present utility model, a plurality of water passing holes are equidistantly opened on the bottom surfaces of the first filter plate 5, the second filter plate 6, the third filter plate 7, and the fourth filter plate 8. The diameters of the water passing holes on the first filter plate 5, the second filter plate 6, the third filter plate 7, and the fourth filter plate 8 decrease sequentially from top to bottom, facilitating the stratification of pollutants by size through the different-sized holes on the four filter plates; and small stones are laid inside the first filter plate 5, fine sand is laid inside the second filter plate 6, an activated carbon layer is arranged inside the third filter plate 7, and a layer of fluffy cotton layer is arranged inside the fourth filter plate 8. Some insoluble impurities are removed by the small stones and the fine sand, the activated carbon can adsorb odors and pigments, and the fluffy cotton is used for the last filtration. A plurality of U-shaped support plates are longitudinally fixedly connected to the inner walls on both sides of the box body 1 in cooperation with the first filter plate 5, the second filter plate 6, the third filter plate 7, and the fourth filter plate 8.

[0020] Working principle: When the present utility model is in use, when sewage is poured into the box body 1 through the holes, the sewage first enters the first filter plate 5, and some larger and insoluble impurities are left in the first filter plate 5 by the small stones. When the sewage then flows into the second filter plate 6, some small and insoluble impurities are left in the second filter plate 6 by the fine sand. Then the sewage will flow into the third filter plate 7, and the activated carbon adsorbs the odors and pigments in the sewage. Finally, the sewage flows into the fourth filter plate 8, and the fluffy cotton filters the small and insoluble impurities in the sewage, improving the high efficiency of water interception and filtration.
