PURIFICATION FACILITY OF CYANIDE POLLUTED SOIL AND PURIFICATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a purification facility of polluted soil which is capable of surely purifying soil of a contaminated area by in situ bioremediation in a low cost and of correspondingly purifying the same even if the soil under a building is polluted. SOLUTION: The purification facility of the cyanide polluted soil is provided with a dissolved oxygen water injection part that is installed in the contaminated soil area to inject dissolved oxygen water into the contaminated soil where cyanide-degrading microorganisms that decompose a cyanide exist and a chemical agent injection part that is installed in the contaminated soil area to the flowing direction of the ground water stream of the contaminated soil area and of the downstream side from the dissolved oxygen water injection part to inject a chemical agent into the contaminated soil that promotes the decomposition of the cyanide by activating the degrading microorganisms.
