APPARATUS DISPOSING POLLUTION WASTE WATER OF A SANITARY LANDFILL

摘要

An installation for treating contaminated wastewater of a waste landfill is provided to prevent environmental pollution due to external leakage of the leachate from the waste landfill by separating and discharging contaminated leachate generated from the inside of the waste landfill, purifying the leachate, and supplying the purified leachate to vegetation around the landfill. In an installation for treating contaminated wastewater of a waste landfill(1), comprising a collected leachate connecting pipe(2) into which leachate collected in the waste landfill flows, and a leachate collecting manhole(10) in which a sludge filtering filter(11), a contaminant filtering filter(12) and a heavy metal filtering filter(13) are stacked from the lower side to the upper side, the installation further comprises: a leachate purification manhole(20) in which a filter(21) for removing toxic substances is installed, and which is connected to an upper part of the leachate collecting manhole through a first discharge pipe(14) to remove toxic substances contained in the leachate flown into the leachate purification manhole; a fermentation manhole(30) in which a salt removal filter(31) is embedded to remove salt by discharging the leachate through a second discharge pipe(23) that has an automatic pump(22) adhered to a lower end thereof when leachate from which the toxic substances are removed within the leachate purification manhole is collected at the lower side of the fermentation manhole; and a third discharge pipe(32) connected to a lower end of the fermentation manhole to discharge salt removed leachate and supply the leachate to vegetation.
