Performance Analysis of Ozone Catalytic Oxidation Sludge and Landfill Leachate

Abstract:

Experimental study of the ozone through catalytic oxidation treatment sludge and rubbish leachate, The impact of different catalysts dosage on absorption rate of O³CODNH₄⁺-NTPpH and other indicators.The results showed that, Dosing Cu-Ni catalyst can increase the absorption rate of ozone, And rubbish leachate ozone absorption rate is higher than the absorption rate of the sludge supernatant; Ozone oxidation catalyst can improve sludge supernatant and leachate the COD removal rate, the optimum mass ratio of 3; Ozone oxidation of sludge supernatant and rubbish leachate is difficult to NH₄⁺-N and organic nitrogen due to preferential oxidation of ozone to convert it to NH₄⁺-N, NH₄⁺-N within the system led to rise, not fall, overall dosing ozone catalyst for the oxidation of NH₄⁺-N had little effect; Dosing catalyst can effectively improve the sludge supernatant and rubbish leachate TP removal, rubbish leachate optimal mass ratio of 3, the optimum sludge supernatant mass ratio of 7; Rubbish leachate pH, with a small amount of catalyst dosage was decreased, while the pH of the sludge supernatant, then with a small amount of catalyst was increased upward trend.
