| 摘要 |
<p>The invention relates to a biomass carrier element for biological treatment systems using the fixed biomass process, said element comprising: a frustoconical tubular body (1) provided with an opening of a smaller diameter and an opening of a greater diameter; S-shaped radial walls (2) defined inside the tubular body (1) and converging at a central shaft (3); curved internal blades (4) extending radially from the internal wall of the tubular body (1) or from the central shaft (3) and disposed, in a cantilevered manner, between the radial walls (2); and a plurality of external blades (5) which are the same height as the tubular body (1), which are perpendicular to the wall of said tubular body (1), and which are evenly distributed around same, designed to facilitate the rotating movement of the carrier element during use.</p> |
