Then, the staff rotates the handle 20, and the rotation of the handle 20 drives the scraper 22 at the top of the rotating plate 21 to rotate relative to the monitoring glass 18 through the connecting tube 19, so as to clean the impurities on the outer wall of the monitoring glass 18, so as to facilitate the clear monitoring operation of the sewage treatment.

[0045] Finally, when the treatment tank 1 is treating sewage, the staff needs to monitor the sewage treatment through the monitoring glass 18. The staff overcomes the elastic force of the spring 25 to press the pressure block 24. The movement of the pressure block 24 drives the gasket 27 at the top of the positioning block 26 to move away from the rotating plate 21 through the connecting rod 23. Then, the staff turns the handle 20. The rotation of the handle 20 drives the scraper 22 at the top of the rotating plate 21 to rotate relative to the monitoring glass 18 through the connecting tube 19, and cleans the impurities on the outer wall of the monitoring glass 18, so as to facilitate clear monitoring operation of the sewage treatment.
