Definitions

  • the present invention envisages a plant for the purification treatment of high- temperature gaseous flows, which is characterized in that it comprises at least one biofiltration bed formed by at least partially porous inert ' media, on the surface and pores of which thermophile microorganisms are adsorbed able to metabolise the polluting components of the gaseous flow to be purified, in particular the volatile organic substances and the formaldehyde, said bed being sprayed in a controlled manner with moistening water so that the spraying water and the gaseous flow to be purified move in the same direction of flow.
  • the two beds which may be designed with different dimensions, operate in synergy so as to ensure efficient removal and a high speed of degradation of the pollutants.
  • the first bed in fact, since it is acted on by the flow from the precipitator, retains most of the pollutants which prevent microbic growth (hydrogen chloride, hydrogen fluoride, heavy metals) , thus allowing the second bed to process pollutants which are non-toxic for the microorganisms .
  • the bed which is first acted on by the polluted flow not only performs initial biodegradation of the VOS and the formaldehyde, but • in particular neutralises the acid compounds owing to its deliberately alkaline nature and retains the heavy metals, preserving the biological activity of the second bed and its duration over time.

Abstract

Ce procédé consiste à faire entrer en contact un flux gazeux d'une température supérieure à la température ambiante d'un milieu saturé en eau, en particulier d'une température de 55-60 °C, constituant l'effluent d'une première installation de purification, avec des micro-organismes thermophile, dans un lit de biofiltration formé par un milieu inerte, de préférence poreux, sur la surface et dans les pores duquel lesdits micro-organismes forment des colonies, pendant une durée suffisante pour produire la métabolisation des composants polluants du flux gazeux en composés gazeux inerte, ledit lit de biofiltration étant humecté par vaporisation d'eau et de substances qui ont un effet nutritif pour lesdits micro-organismes introduits dans ledit flux gazeux.
