[0024] Open the protective cover 3 and pour the wastewater into the wastewater treatment barrel 2. The wastewater passes through two layers of filter screens 8 as it falls downward, and the silicon crystals remain on the surface of the filter screens 8. The other parts move downward to the bottom and are discharged through the drain pipe 14 after being stationary for a period of time. When the silicon crystals on the surface of the filter screen 8 need to be taken out, the dual-axis motor 9 works to drive the support ring 7 to move outward, and the support ring 7 and the filter screen 8 leave the wastewater treatment barrel 2. When the filter screen 8 moves outward, the scraper rod 11 contacts the surface of the filter screen 8, scrapes off the silicon crystals on the surface of the filter screen 8, and drops them downward into the discharge trough 13 for collection.
