Abstract
An apparatus for treating soil contaminated by organic compounds wherein an ozone containing gas is treated with acid to increase the stability of the ozone in the soil environment and the treated ozone applied to the contaminated soil in a manner adapted to decompose the organic compounds; one embodiment of the apparatus comprises a means to supply ozone as a gas-ozone mixture, a stability means to treat ozone obtained from the supply and distribution means to apply the stabilized gas-ozone to soil. The soil may be treated in situ or may be removed for treatment and refilled.
Claims11
An apparatus for treating soil contaminated with organic compounds comprising:
- a. an ozone generator adapted to receive an oxygen containing gas from a gas supply means, that generates ozone from oxygen in the gas to produce a gas-ozone mixture;
- b. ozone stabilizing means, containing an acid, connected to the ozone generator by a first pipe for receiving the gas-ozone mixture from the ozone generator, that stabilizes the gas-ozone mixture by contacting the mixture with the acid to produce a stabilized gas-ozone mixture, wherein the acid has a pH of about (1) or less;
- and
- c. gas-ozone mixture distribution means, connected to the ozone stabilizing means by a second pipe for receiving the stabilized gas-ozone mixture, that distributes the mixture to the soil as a gas.
