Abstract:

The electro-multiphase catalysis is a new technique to treat wastewater.Some effective,highly selective and ever lasting catalysts are studied and produced by changing the components, valences and constructive patterns of the activesites of catalysts.The COD and colourity of the wastewater can be reduced while the wastewater passing through the electro-multiphase catalysis reactor at room temperature and atomospheric pressure.On the one hand,high reactive hy droxyl radicals.On can be produced to degrade organic pollutants nonselectively.On the other hand,the pollutants of wastewater can be cataly zed and dest royed selectively at the surface of the catalyst activated by electric field.The wastewater treatment of fertilizer plants with electro-mult iphasecatalysis is described on a scale from laboratory to industrialization

Key words: elect ro-catalyst, electro-multiphase catalysis, wastewater
