<p>The vertical-horizontal filter unit for biological purification of polluted water from compost production, wine- and fruit processing/animal husbandry and/or press water from bio fermentation, comprises upper zone (3) having inlets (1) for the polluted water and arranged below a lower filter zone (5), removal point (7), and a barrier layer (4) with openings arranged between the upper and the lower filter zones made of gravel and sand. The filter unit is sealed against the soil on the sides and at the bottom. A medium that contains organic carbon is introduced into the lower filter zone. The vertical-horizontal filter unit for biological purification of polluted water from compost production, wine- and fruit processing or animal husbandry and/or press water from bio fermentation, comprises an upper zone (3) having inlets (1) for the polluted water and arranged below a lower filter zone (5), a removal point (7), and a diagonally passing barrier layer (4) with openings arranged between the upper and the lower filter zones made of gravel and sand. The filter unit is sealed against the soil on the sides and at the bottom. A medium that contains organic carbon is introduced into the lower filter zone over a device. The upper filter zone and the lower filter zone are homogeneously formed. The upper zone is an aerobically filter zone, in which a nitrification of the polluted water takes place and the lower zone is an anaerobic filter zone with denitrified microorganism, in which premixing and nitrification of the nitrified polluted water treated in the upper filter zone is carried out with the medium having organic carbon. Fermenting residues or residues from animal husbandry and methanol or acetic acid are introducible over the device. The upper filter zone possesses removal device for the biologically purified wastewater. A separately arranged container takes up the waste and supplies to the lower filter zone. The container possesses a device for dosing of the carbon-containing medium and/or the organic substances. Valves and/or pumps are arranged in the upper and/or lower filter zones. Filter bodies with high phosphorus linking capacity are arranged in the upper and/or lower filter zone. Microorganism and/or substances are supplied over the device in the lower filter zone. The microorganism and/or substances cause or support a metabolization of the material containing in the polluted water. The microorganisms are genetically modified to bacteria strains or yeast strains. An independent claim is included for a method for purification of polluted water through vertical-horizontal filter unit.</p> |
