摘要： Industrial waste system having lateral lined trenches in a floor comprising spaced parallel side plates with downwardly and inwardly inclined lower sections joined to form a V bottom having a lengthwise gradient sufficient to promote flow of liquids and matter capable of suspension in the liquid from one end to a discharge point at the other end, side wall shoulders for supporting the side plates within the trench with the upper edges of the plates close to floor level, internal filtergrid support shoulders extending horizontally along the inside walls below floor level having filter grids thereon, power driven sprocket and chain means disposed on opposite sides of the side plates and extending substantially the length of the trench liner, carrying transverse scraper bars at a level to scrape the upper surface of the filter grids, and a similarly constructed trunk trench connecting the discharge ends of the lateral trenches, and means for collecting the liquids separate from the waste collected by the scraper bars.
