Continuous purification of liquids containing biodegradable contaminants such as halogenated hydrocarbons, polycyclic aromatics or plant protectants

摘要

A continuous purification in an O2 source-containing vortex reactor of liquids loaded with biodegradable contaminants which can be mineralized by microorganisms is such that the process is effected in presence of adsorbent particles.- DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an apparatus for the process comprising an inverted cone-shaped vessel at least partly packed with adsorbent particles and having a vortex zone (1), an upper, a cylindrical sedimentation zone (2), optionally inlet valves (3,4), optionally outlet valves (5, 6), (the inlets and outlets optionally being connected by a recycling device), an overflow (7) and, in the lower part of the vortex zone, a sieve plate (9)
