Abstract

L'invention concerne un procédé et une unité de traitement d'eaux résiduaires utilisant le mode oxydation par contact. La structure de support des micro-organismes est constituée par un tapis fibreux non tissé offrant une structure en réseau à trois dimensions, ayant une masse spécifique de 0,01 à 0,40 g/cm**3 et une épaisseur de 15 à 30 mm, fait de fibres synthétiques d'une taille de 50 à 4000 deniers. On dispose plusieurs de ces tapis dans la cuve d'aération parallèlement l'un à l'autre à un intervalle de 20 à 100 mm Ces structures ont un effet traitant plus poussé, une plus longue durée d'utilisation et un moindre taux de production de boues en excès.The invention relates to a method and a unit for treating waste water using the contact oxidation mode. The microorganism support structure consists of a non-woven fibrous mat providing a three-dimensional network structure, having a specific mass of 0.01 to 0.40 g / cm ** 3 and a thickness of 15 to 30 mm, made of synthetic fibers with a size of 50 to 4000 denier. Several of these mats are placed in the aeration tank parallel to each other at an interval of 20 to 100 mm.These structures have a more thorough treatment effect, a longer life and a lower production rate of excess sludge.
