The upper surface of the first filter plate 221 is inclined. A brush plate 222 is fixedly installed at one end of the first filter plate 221 away from the second filter plate 224. A partition strip 223 is fixedly installed above one end of the first filter plate 221 close to the brush plate 222. The partition strip 223 is arc-shaped. One side of the brush plate 222 prevents floating objects from floating up and down through the bristles, preventing them from floating above the first filter plate 221. Clamping grooves 225 are fixedly installed at both the upper and lower ends of the second filter plate 224. The clamping grooves 225 are U-shaped.

The two ends of the valve pipe 237 are respectively communicated with the connecting pipes 236. Through holes are equally spaced on both sides of the floating plate 233. A water guide plate 234 is fixedly installed above the floating plate 233. The water guide plate 234 is arc-shaped. There is a valve on the valve pipe 237 to facilitate the communication between both sides of the second partition plate 214 and transmit the filtered sewage.

[0029] A microecological filter bed includes a microecological filter bed body 100 arranged on one side of the domestic sewage filtering mechanism 200, and the microecological filter bed body 100 is communicated and arranged.

[0030] Working principle: Sewage enters the communicating pipe 215 through the input pipe 216 and is discharged. The sewage slowly accumulates and precipitates. When the sewage overflows the first filter plate 221, the first filter plate 221 will block the floating objects. At the same time, the brush plate 222 will prevent the floating objects from floating above the first filter plate 221. The sewage passes through the first filter plate 221 and the second filter plate 224 and flows into the space between the second partition plate 214 and the first partition plate 213. The filtered sewage is extracted through the corrugated hose 231 and the water inlet nozzle 232. The sewage is discharged into the interior of the micro-ecological filter bed body 100 through the connecting pipe 236. If the pool between the second partition plate 214 and the first partition plate 213 needs to be cleaned, the water in the pool is discharged into the pool on the other side of the second partition plate 214 through the valve pipe 237 for supplying the micro-ecological filter bed body 100 at any time. When the filter pool 211 and the pool on one side of the first partition plate 213 are cleaned or repaired, the pools on both sides of the second partition plate 214 are filled in advance to prevent the cleaning and repair time from being too long.

[0031] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
