Chemistry and Application of Ozone and Ozone/UV Light for Water Reuse-II

摘要

This report describes the continuation of an experimental study to elucidate the chemistry of Ultraviolet light (UV) enhancement of ozone (O3) oxidation of refractory organics in wastewater. The overall purpose of this study is to reduce the fixed and operating costs of removing these constitutents prior to water reuse. The study consisted of (1) an investigation of the synergistic effect of ozone and wave-length of UV light in breaking carbon-chlorine bonds (2) evaluation of the UV-ozonation process to oxidize amino compounds (3) survey of heavy metal ion interference in the UV ozonation system, and (4) accumulation of data from bench and pilot plant tests on industrial effluent from a chlorophenol plant in the Northwest.
