Abstract:
본발명은유해식물인가시박을열분해시켜수득되는바이오차를처리하여토양에서식물의항생물질흡수를억제하는방법에관한것이다. 본발명의바이오차를이용한식물의항생물질흡수억제방법에의하면, 항생물질로오염된토양에바이오차를적용할경우에토양에서식량식물로의항생물질흡수가매우효과적으로감소될수 있다.
Abstract:
PURPOSE: A purification method of heavy metal contaminated soil using oyster shells and chicken bones, and a heavy metal contaminated soil processing agent are provided to economically purify the contaminated soil. CONSTITUTION: A purification method of heavy metal contaminated soil comprises the following steps: calcining oyster shells and chicken bones; and applying the calcined oyster shells and chicken bones to the heavy metal contaminated soil. The calcining process is performed in the temperature over 850deg C.
Abstract:
The present invention relates to a method for purifying water polluted by trichloroethylene(TCE) using biochar derived from Buffalo Weed(Ambrosia trifidaL.), and more specifically, to a method for purifying water polluted by TCE, by preparing bicochar using Buffalo Weed and applying biochar derived from Buffalo Weed to water polluted by TCE.
Abstract:
The present invention relates to a method for manufacturing a biochar using sewage sludge and a novel purpose for a heavy metal adsorption of the biochar manufactured by the same. More specifically, the present invention relates to Pb-immobilization effect in soil contaminated by heavy metal, derived from a biochar manufactured in a specific process using sewage sludge. The biochar manufactured from sewage sludge has a function of adsorbing heavy metal in soil which is contaminated by heavy metal, and is especially effective in adsorbing lead (Pb). Therefore, the biochar can be useful as a material for improving and stabilizing soil which is contaminated by lead (Pb). Moreover, since sewage sludge which requires a delicate treatment is used as a component, the present invention is capable of providing solutions to both recycling of waste resource and prevention of environmental pollution.
Abstract:
PURPOSE: A purifying method of heavy metal contaminated soil using the heat-treated domestic fowls waste and a soil treatment are provided to perform the calcinations of the eggshell in the high temperature thereby mixing the eggshell to the heavy metal contaminated soil. CONSTITUTION: A surface of an eggshell and interference materials in the eggshell are removed by the cleaning brush. The eggshell is dried in a dry oven. The eggshell is crushed by a crusher. The sieved eggshell is put in a melting pot for the calcinations. The heavy metal contaminated soil is purified.
