An anoxic and/or aerobic biological reactor for the purification of waste water and/or liquid residues with high concentrations of contaminating loads

摘要

An anoxic and/or aerobic biological reactor (R) for the purification of waste water and/or liquid residues with high concentrations of contaminating and/or toxic loads.;The pieces of fabric forming the support elements (S) as per the invention consist in a rough, tough, open texture special fabric facilitating the binding onto it of the bacteria and microorganisms to form the biofilms on both sides of the fabric, this latter being made of plastics material and having a high mechanical strength especially in the vertical direction. The fabric is submitted to a previous scraping/carding operation that increases its surface roughness to thus improve the binding.;The open enclosure can be rectangular and of the piston flow type or oblong and of the roundabout type. The support elements can be arranged in the enclosure in a parallel arrangement with respect to the major longitudinal axis, and/or in a spike like arrangement and with a spacing from the longitudinal axis, in a slanted arrangement on either side thus being at an angle with respect to said longitudinal axis.
