THE COMPOSITE REACTIVITY CLEAN APPARATUS OF DIRTY AND WASTE WATER AND THE CLEANING METHOD THEREOF

摘要

A composite reactive purification device for leachate treatment which is constructed in a simple structure to reduce installation cost and operating cost, and which effectively removes various nitrogen components and various harmful substances such as heavy metals contained in leachate by composite reaction of an adsorption layer, aerobic microorganisms and anaerobic microorganisms, and a composite reactive purification method for leachate treatment using the same are provided. A composite reactive purification device(1) for leachate treatment comprises: an adsorptive removing layer(3) comprising 80 to 90 wt.% of a mixture of sand and loess, 5 to 10 wt.% of bentonite and 5 to 10 wt.% of zeolite to adsorb and remove heavy metals and organic matters contained in leachate; an aerobic permeable barrier layer(2) comprising 10 to 30 vol.% of a polyurethane carrier(5a) carried with activated carbon and 70 to 90 vol.% of a mixture of sand and loess, wherein aerobic microorganisms are attached to the polyurethane carrier(5a) to perform nitrification while consistently maintaining aerobic conditions; an anaerobic permeable barrier layer(4) comprising 10 to 30 vol.% of a polyurethane carrier(5b) carried with activated carbon and 70 to 90 vol.% of a mixture of sand and loess, wherein anaerobic microorganisms are attached to the polyurethane carrier(5b) to perform denitrification while consistently maintaining anaerobic conditions; and non-woven fabric layers(9a-9d) formed on upper and lower surfaces of the adsorptive removing layer, the aerobic permeable barrier layer, and the anaerobic permeable barrier layer, wherein the adsorptive removing layer, the aerobic permeable barrier layer, and the anaerobic permeable barrier layer are sequentially stacked in a purification device case from an upper side to a lower side.
