Heavy metal ion precipitation device for landfill leachate

The heavy metal ion precipitation device comprises a device main box body, and the same W-shaped partition plate is fixedly welded to the front side inner wall, the rear side inner wall, the left side inner wall and the right side inner wall of the device main box body. And a mounting box fixedly mounted on the inner walls of the front side and the rear side of the device main box body is fixedly mounted at the top of the W-shaped partition plate. According to the device disclosed by the utility model, when the rotating drum is used for driving the stirring rod on the outer side of the rotating drum to stir medicaments and sewage in the precipitation cavity, the stirring rod also rotates automatically to stir the medicaments and the sewage in the precipitation cavity, so that the stirring efficiency is improved; the filter screen is driven to continuously shake up and down, so that sewage discharged by the sediment discharging pipe can be better filtered, the phenomenon that the filter screen is blocked is gr
