PROCESS AND APPARATUS FOR MAINTENANCE OF SOLID MATTERS CONTAMINATED WITH ORGANIC HARMFUL SUBSTANCES

摘要

the remediation of solids contaminated with organic contaminants.in particular, soils contaminated with polycyclic aromatic hydrocarbons (pah) (then) solid after the eventual dilution and mechanical degradation, mixed with mikroemulzu00ed.the organic impurities solubilizuju00ed in non-polar part of microemulsion and microemulsion, in particular temperature changes into the phase rich in surfactants and phase containing harmful substances.if used in microemulsion of biodegradable components, can be cleared solid substance, in particular ground, again to export to the outdoor environment.device for the implementation of this method consists of an extraction device (3), in which the polluted substance is mixed with the mikroemulzu00ed and impurities concentrate in the non-polar oil phase.in a separation device (6) with the filtered solid is separated from the contaminated microemulsion, which subsequently in the separator stages (8) into the aqueous phase rich in surfactants.which collect in the tank (11) and an oil phase containing harmful substances (oil tank (12). the final odbouu0155
