• Coagulation process is usually used as a method of treating refractory substances in wastewater. But, it cant often satisfy target water quality within practical coagulant dosage. In case of treating the effluent from coagulation process, the AOP (Advanced Oxidation Process), an oxidation/decomposition process which combines ultraviolet, ozone, and hydrogen peroxide, is looked upon as a method of treating the effluent from coagulation process. However, the abundant amount of oxidant and ultraviolet irradiation needed for oxidation are hampering the practicalization of this process. The authors conducted a research on the application of the AOP (ozone/hydrogen peroxide treatment) for pretreatment of secondary coagulation process using the effluent from coagulation process of a landfill site leachate treatment plant as raw water. The D-TOC removal by coagulation treatment using AOP treated water of raw water was higher than that using raw water, despite the D-TOC of the former was lower than that of the latter. Considering that the D-TOC removal was occurred during the AOP, it was assumed that the organic compound underwent changes to more susceptible to reaction with coagulant during oxidative decomposition. From this result, it was considered that using the AOP for pretreatment of coagulation process could achieve a significant decrease in coagulant dosage, a space-saving in the sludge treatment facility, and a saving in sludge disposal costs.
