The influence of reaction conditions in the oxidation of organic compounds of nuclear laundry water by ozone

摘要

This paper presents a summary of degrading organic compounds of nuclear laundry waternby ozonation in different conditions of pH, hydrogen peroxide and ultraviolet radiation.nThe degradation of organic compounds was analysed by chemical oxygen demand (COD), totalnorganic carbon (TOC) and biochemical oxygen demand (BOD). The optimal degradation conditionsnwere at pH 7 with ozone, UV radiation and hydrogen peroxide addition. The transfer of ozonenincreased significantly, thus resulting in decreased treatment time compared to ozone treatmentnalone. The reductions of COD, TOC and BOD were 46%, 32% and 70%, respectively.
