Treatment method of harmful substance
Abstract
PROBLEM TO BE SOLVED: To provide a treatment method of harmful substances which can efficiently recover harmful substances from plants absorbed the harmful substances to process while clarifying contaminated soil.SOLUTION: There is provided the treatment method of harmful substances, wherein radioactive substance absorbing plants are cropped in a contaminated area contaminated with radioactive substances, the radioactive substances are accumulated in the radioactive substance absorbing plants, the radioactive substance absorbing plants containing the radioactive substances are harvested, and the radioactive substances contained in the radioactive substance absorbing plants are processed. The treatment method of harmful substances includes: a hydrothermal decomposition treatment step (S13) for counter-contacting the harvested radioactive substance absorbing plants with pressurized hot water, shifting the radioactive substances to the hot water to extract as hot water discharge liquid while extracting a biomass solid content in which the radioactive substances are removed from a side different from the side discharged the hot water discharge liquid; and a radioactive substance treatment step (S14) for treating the radioactive substances from the hot water discharge liquid.

A waste melting furnace has a coke layer formed therein, and an annular combustion space formed circumferentially of the coke layer below an upper surface thereof and communicating with the coke layer. A depending wall projects downwardly from an upper position of the combustion space to mark a boundary between the combustion space and the coke layer. A waste is fed in powder form into the combustion space, and burned in the combustion space and the coke layer to be melted and slagged. The depen...

PROBLEM TO BE SOLVED: To utilize waste containing organic materials for manufacturing high quality cement clinker without harmfully affecting the environment and deteriorating the performance of an electrostatic precipitator. SOLUTION: The waste A containing organic materials is pulverized in a wet mill 11 with an addition of a solvent B which gives flowability, and then, this is fed into a kiln inlet 5B of a rotary kiln 5 of a cement calcining plant, a calcining furnace in front of the rotary k...

A method is provided for remediating porous contaminated material. In the method, fuel material is combined with the contaminated material and a smoldering combustion process is initiated in the contaminated material to remediate the contaminated material. Control systems are provided to control the smoldering combustion process. The contaminated material may include oily waste, asbestos fibers, and/ or at least one of a chlorinated solvent, a polychlorinated biphenyl (PCB), a dioxin, a furan an...
