After the regulating work is completed, the leachate is output through the suction output pipe (3) and enters the next processing step. In this process, floating impurities in the sewage leachate are collected by the sewage impurity removal auxiliary mechanism. The control slide rail (6) drives the concave support plate (803) to move, thereby driving the bearing rod body (804) to move. The bearing rod body (804) inserted into the liquid and the scraping block (806) arranged on the side of the bearing rod body (804) adhere and filter the floating impurities. After reaching the collection component at one end of the regulating tank body (1), the control slide rail (6) and the lifting control rod (801) are used in coordination, and the cleaning scraper (1003) arranged on the fixed plate body (1002) and the auxiliary cleaning brush (1005) on the cleaning scraper (1003) clean the filtered floating impurities. The cleaned floating impurities fall into the filter collection box (1101) for collection.
