Research on the Removal of Organic Contaminants of Photoinitiator Wastewater under Fenton Condition
Abstract:
Photoinitiator wastewater and its by-products contain many kinds of contaminant organics which induces COD in a high level, as a result of which, it is essential to take measures to reduce the organic contents. Interference effect of H2O2 and Cl-1 on COD testing was investigated initially. The main parameters that govern the complex reactive system, i.e. H2O2/COD, H2O2/Fe2+, pH in solution was also studied by using L25 (56) orthogonal test so as to make sure the best degradation condition. It was shown that H2O2/COD=0.69H2O2/Fe2+=10:1pH=3 could ascertain the COD removal in a high level.
