MULTI-FUNCTIONAL ARTIFICIAL SOIL COMPOSITION FOR LANDFILL LEACHATE, MANUFACTURING METHOD THEREOF AND LANDFILL LINER STRUCTURE USING IT

摘要

The present invention relates to a functional artificial soil composition is for landfill leachate and wastewater treatment, more particularly zeolite 18 to 20 parts by weight perlite 12 to 15 parts by weight of diatomaceous earth of 15 to 20 parts by weight of calcium oxide 15 to 20 parts by weight, cement 25-30 parts by weight of aluminum powder of 0.1 to 0.3 parts by weight of aluminum sulfate, the metal sulfate (Al ₂ (SO ₄₎₃₎ or, for landfill leachate and wastewater containing ferrous sulfate (FeSO ₄₎ 1 to 5 parts by weight water was added to the functional artificial soil composition and the mixture of raw materials consisting of the parts by the steps to create a slurry; A step of curing for 1-3 hours at a temperature of 90 to 110 ℃ the mixture of the slurry; The said curing a mixture comprising: processing for 10 to 15 saturated with from 1 to 3 hours water vapor pressure in air pressure; relates to a landfill leachate and wastewater treatment is for a functional artificial soil method as characterized in that said, also the bentonite layer, MFM layer and to a landfill liner-based structure which comprises a mixed layer of normal soil. ; When using the artificial soil of the present invention to use as the material of a landfill liner-based structure can be, as well as waste water treatment to obtain an organic reducing effect in a landfill structure itself. ; Functional artificial soil porosity, leachate treatment, landfill liner-based structure
