For example,Seattle, Washington, contracts with two private companies to collect MSW from homes. Those companies take waste to city-operated transfer facilit...
PURPOSE: To effectively desorb hazardous organic compounds and heavy metals from contaminated fine soil particles by performing soil washing treatment after classifying contaminated soil per particle size, thereby washing a large quantity of contaminated soil in a short time with high efficiency. ...
: Contaminated soil 4b under a caisson is excavated by an excavator 3 in a work room 2 in a concrete skeleton (a caisson skeleton) 1b forming the work room 2 installed in the lowest part of a concrete skeleton 1, and agitated and exposed to air to release the VOC from the soil. ...
PROBLEM TO BE SOLVED: To effectively utilize decontaminated soil by decontaminating soil contaminated with a volatile organic chlorine compound. SOLUTION: Chemical reaction is promoted by digging contaminated soil and sufficiently mixing it with quick lime or the like by a mixer. The contaminated ...
PROBLEM TO BE SOLVED: To enable to easily cope with a distribution situation of contaminated soil and carry out purification treatment of a contaminated material in soil economically and in a short period. SOLUTION: An area containing soil contaminated with a hazardous material is classified in a ...
and mixing the contaminated soil with the quick lime to facilitate sucking of the contaminated gas and cleaning speed can be made fast and cleaning can be performed without volatilizing the contaminated gas into the atmosphere, and at the same time, the contaminated groundwater can be cleaning. ...
