Performance Analysis of Ozone Catalytic Oxidation Sludge and Landfill Leachate

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.
