<p>The invention relates to a plant for purifying waste water by neutralization with clay and stone dust, which reduces the risk of polluting the environment to a minimum level. According to the invention, the purifying station uses an emulsion of fermented clay in a battery-type construction (BMA) with several compartments and stone dust in specific constructions, namely some sand-clearing batteries (BDz), some settling tanks (BD) having some compartments (c.b.APp) for bubbling the clay emulsion, the stone dust and the waste water, a settler-spillway channel (CDD) having a foundation of sinusoidal grate type with thermal- and hydro-insulating masonry consisting of reinforced concrete double walls, between which there is injected fermented clay, said walls being provided with linking spurs, the partitioning walls in the water flow direction having some siphoning tubular elbows, oriented with the hole upside down, the resulting sludge being settled together with the garbage and vegetable waste on thermal- and hydro-insulating pyramidal-frustum shaped platforms, interposed as rows and columns, lined with clay fermentation extract at the bottom side, separated by gravel (sand), and the purified water is improved and controlled in an artificial swamp made with dikes and thermal- and hydro-insulating partitioning walls.</p> |
