The biomass on the rotating bio-disc 3 is automatically compensated according to the change of the organic load, and when the organic matter in the sewage increases, the microorganism increases, and conversely, when the organic matter in the sewage decreases, the microorganism decreases. Therefore, when sewage is treated, the sewage treatment device is not easily influenced by sudden changes of flow and load and power failure, and can be conveniently managed.

Referring to fig. 2 and 3, there is a water seepage bottom plate 4 fixedly mounted at the bottom of the circular foundation pit 1, a fine water seepage hole (not shown in the figure) is provided on the water seepage bottom plate 4, the water seepage bottom plate 4 is a conical shape with a middle downward depression, a storage cavity 5 for water flow is provided below the water seepage bottom plate 4, a drainage pipeline is connected on the outer side wall of the storage cavity 5, and therefore the water flow after treatment is conveniently discharged. A sludge discharge pipeline 11 is arranged in the middle of the water seepage bottom plate 4, and a cleaning mechanism 6 for cleaning the sludge on the water seepage bottom plate 4 is also arranged in the circular foundation pit 1.

Can circulate to infiltration bottom plate 4 after domestic sewage clears up through biological rotating disk 3 on, rivers can see through infiltration bottom plate 4 and circulate to storage chamber 5 after the processing, and the mud that mixes in the rivers can persist on infiltration bottom plate 4, utilizes clearance mechanism 6 to clear up the mud on the infiltration bottom plate 4 this moment.

Referring to fig. 3, the cleaning mechanism 6 includes a rotating rod 61 vertically disposed at a central axis position of the circular foundation pit 1, the end of the rotating rod 61 extends into the sludge discharge pipe 11, three fixing rods 62 fixedly connected to the side wall of the sludge discharge pipe 11 at equal intervals along the circumferential direction, a bearing sleeve 63 fixedly connected to the end portion adjacent to the three fixing rods 62, and the end portion of the rotating rod 61 passes through the bearing sleeve 63 and is rotatably connected with the bearing sleeve 63.

At the top fixedly connected with of circular foundation ditch 1 support plate 12 along 1 diameter direction of circular foundation ditch, the staff can walk in support plate 12 to can make the staff arrive the bank fast and carry out work. A driving motor 64 is fixedly connected to the upper surface of the supporting plate 12, and the top of the rotating rod 61 passes through the supporting plate 12 and is fixedly connected with a motor shaft of the driving motor 64.

A support rod 66 is fixedly connected to the side wall of the rotating rod 61 through a fastening bolt 65, and a scraper 67 contacting the water-permeable bottom plate 4 is connected to the bottom end of the support rod 66. The scraper 67 and the support rod 66 are connected in an articulated manner, so that the scraper 67 can be always in contact with the water seepage bottom plate 4.

When needs are handled the mud on the infiltration bottom plate 4, start driving motor 64, driving motor 64 can drive dwang 61 and rotate, can drive scraper blade 67 when dwang 61 rotates and remove along infiltration bottom plate 4 to can strike off the mud on the infiltration bottom plate 4. By setting the water penetration bottom plate 4 to be conical with a downward concave center, the scraped sludge can be made to slide down into the sludge discharge pipe 11 along the conical surface.

The scraping plates 67 may be worn during the contact with the water permeable base plate 4, so that there may be a gap between the scraping plates 67 and the water permeable base plate 4 after a long period of use, thereby deteriorating the effect of treating the sludge. A kidney-shaped hole 611 is formed in the side wall of the rotating lever 61 along the axial direction of the rotating lever 61, and the fastening bolt 65 passes through the rotating lever 61 and the support lever 66 in this order and is locked. When the scrapers 67 are worn, the fastening bolts 65 are loosened so that the support rods 66 and the scrapers 67 move downward at the same time, and when the scrapers 67 and the water-permeable bottom plate 4 contact each other, the support rods 66 are locked by the fastening bolts 65.
