<p>The invention relates to a process and a plant for the biologic purification of waste water resulting from individual domestic consumers. According to the invention, the process comprises the discharge of waste water over a biomass consisting of grass or food waste, degradation of the organic component of the residue in contact with the biomass by means of micro-organisms, and oxygenation thereof with a view to further carrying on the residue degradation process, concomitantly with the filtering separation of coarse residues from water to be purified, followed by gravity conveying the filtered water to be stored and discharged after reaching a preset level. The claimed plant for biologically purifying domestic waste water comprises a collecting tank provided with a filtering plate above which there is formed an upper enclosure, while below said plate there is formed an enclosure confined at its lower part by an inclined bottom ensuring the gravity conveyance of purified water to a storing tank.</p> |
