COMPOSITION FOR SOIL STABILIZATION, IMPROVEMENT, HARDENING, AND COMPOST FERMENTATION PROMOTION OF CONTAMINATED SEDIMENT, AND METHOD OF MANUFACTURING THE SAME

摘要

Disclosed are a composition for facilitating soil stabilization, improvement, hardening, and compost fermentation of contaminated sediment, and a method for manufacturing the same. The composition for facilitating soil stabilization, improvement, hardening, and compost fermentation of contaminated sediment according to the present invention comprises: 40-75 parts by weight of silica powder (SiO_2) used for absorbing water of the contaminated sediment; 2-7 parts by weight of alum for condensing and adsorbing heavy metals of the contaminated sediment; 10-30 parts by weight of calcium carbonate for regulating pH fluctuations of the contaminated sediment; 10-30 parts by weight of diatomite for a soil composition ratio and restoration of the contaminated sediment; and 5-25 parts by weight of magnesium sulfate (MgSO_4) for hardening components; and 2-8 parts by weight of sodium sulfate for plant growth, wherein the silica powder is characterized by being a powder component comprising a paper cinder or fly ash cinder.
