1results about How to "Avoid decimation" patented technology

This utility model relates to the field of wastewater treatment technology, and more particularly to a stratified separation device for construction wastewater. It includes a support frame with a through hole in the middle. A hollow ring is fixedly connected to the upper surface of the support frame, and a treatment tank is inserted into the hollow ring. A fixing assembly for securing the treatment tank is provided on the support frame. A first electric push rod is fixedly installed on the treatment tank. The drive end of the first electric push rod is connected to a perforated pressure plate via screws. Filter cloth is connected to the lower surface of the perforated pressure plate via multiple Velcro straps. An opening is provided on one side of the treatment tank. This utility model effectively avoids extracting bottom sediment, eliminates the need for secondary treatment of the extracted supernatant, greatly improves the efficiency of separating the supernatant from the sediment in wastewater, and ensures the quality of the treated supernatant.
