| Abstract: | The paper takes gas drilling wastewater as the research object. The wastewater treatment by coagulation and gel breaking was oxidized by ozone. The optimum conditions of ozone oxidation, ozone/hydrogen peroxide oxidation and ozone/ferrous ion oxidation for CODCr removal were studied. The result shows ozone/hydrogen peroxide has the best CODCr removal efficiency, when the dosing quantity of ozone was 0.5 g/h·L and hydrogen peroxide was 0.4 %, the oxidation ptt was 10 and the oxidation time was 2 hours, the CODCr removal efficiency was the optimum, the CODCr removal rate reaches 69.1%. |
