Treatment of Organic Hazardous Wastes with Ozone and Ultraviolet Radiation

摘要

A Hydrazine Waste Water Treatment System (HWWTS) has been designed andconstructed for the purpose of treating waste waters contaminated by hydrazine propellants generated during space launch operations at Vandenberg AFB. This system utilizes ozone and ultraviolet radiation to reduce the propellant contaminants (and chemical intermediates formed from them during treatment) to innocuous products. In this report, the treatment of other organic wastes, generated during routine operations, is considered. Of particular interest are alcohols (methyl and isopropyl), chlorinated hydrocarbons (trichloroethylene and 1,1,1-trichloroethane), and aromatic wastes (benzene and toluene). The literature was reviewed for each of the materials of interest experiments were also carried out for each of the materials. The results of these studies indicate that the alcohols (and, most likely, a variety of other water soluble organic materials) should be readily treatable in the HWWTS. Other organics that are sparingly soluble in water, such as the chlorinated hydrocarbons and aromatics investigated here, should also be treatable. Treatments of chlorinated hydrocarbons and aromatics could generate low levels of gas emissions, averaging 0.05-0.08 lb/hr during the treatment time, due to the low water solubility and high volatility of these materials. Even these figures are likely to be worst case emissions, for reasons discussed herein. Hazardous Wastes, Ozone/uv Treatment, Organic Wastes, Toxic Wastes, Ozone Treatment.
