Abstract

L'invention a pour objet un procédé et des appareils pour le traitement des eaux usées. On envoie ces eaux dans le fond d'un réservoir F contenant une couche de gravier S surmontée d'un filet convexe N et on fait fluctuer le niveau de ces eaux dans une bande de fluctuation H4 entre un niveau inférieur LWL et un niveau supérieur HWL. L'invention est applicable au traitement in situ des eaux usées ne contenant pas de métaux lourds.The invention relates to a method and apparatuses for the treatment of waste water. These waters are sent to the bottom of a reservoir F containing a layer of gravel S surmounted by a convex net N and the level of these waters is made to fluctuate in a fluctuation band H4 between a lower level LWL and an upper level HWL . The invention is applicable to the in situ treatment of wastewater not containing heavy metals.
