BDD电催化氧化及高级氧化技术在印染废水的应用

he dyes-producing wastewater characteristics in all processes were detail analyzed in the paper. And the advanced oxidization technology such as electro-catalysis oxidation with BDD film electrode, photo-catalytic, Fenton, wet oxidation and supercritical water oxidation for the dyes-producing wastewater treatment were summarized. With above technology, the efficiency and of treatment were high, and the quality as well as the chemical characteristics stability. The effluent had highly biodegradability and low-toxicity. When adding the Fe2+, H2O2 appropriately, the treatment effect would significantly improve such as removal efficiency of COD being more then 90% and chromaticity removal obviously. The principle of the BDD film electrode electrochemical oxidation was also analyzed. It was indicated that the BDD film electrode would had widely applications for the wastewater treatment of dyes and pesticides producing, which were Nonbiodegradable Organic Wastewater, and high COD removal efficiency.
