Study on Catalyst for Catalytic Ozonation to Leachate and Catalytic Process
Five kinds of catalyst were prepared with Chromium, cadmium, cobalt, copper, nickel loading on the γ-Al2O3. Catalyst loading rate, effects to the ozone suction rates and water quality change situation of catalytic ozonation to leachate were studied. It can be found that when the mO3/mCOD equaled 0.11, 0.15 and 0.26 separately, and mCatalyst/mCOD fixed at 5, the cobalt has the highest loading rate, the cadmium catalyst could improve the ozone absorption rate, the chromium catalyst makes against the ozone absorption rate, the copper catalyst can increase the COD removal rate and the nickel catalyst has advantages for the NH3-N removal rate. Results indicate that: the leachate COD removal rate increased by 20.2 percent by the copper catalyst adding and the NH3-N removal rate raise 20.7 percent with the nickel catalyst; the best dosage of the ozone in catalytic oznoation is mO3/mCOD at 0.12 to 0.13; the degree of oxidation is exited.
