The purpose of this study is to inform knowledge of GD-NTP process using Non-temperature plasma among advanced oxidation processes (AOP) using generated influent from public sewage treatment plant. Two independent variables were set for environmental variable and efficiency, and then temperature and time were specified. We then investigated the treatment efficiency of these two independent variables and examined the optimal conditions for treatment efficiency. To find the optimal conditions, the study plan was expressed using a central composite experimental design (CCD). Therefore, in this study, OH radicals generated in the GD-NTP process are examined in terms of the time and temperature conditions in the CCD test method. Based on the results optimal conditions for the removal rate of organic materials are suggested. Experiments have been carried out to estimate the decomposition rate k based on the assumption that high decomposition rates will lead to high decomposition efficiency. In case of TCOD, 40 ℃ and 4 hour points were analyzed as optimal points and the correlation of time was more significant than correlation of temperature. In the case of TSS, 40 ° C and 4 hours, as TCOD, were analyzed to be optimal points, and the significance of the correlation between the square of the temperature and the square of the time was more complex than the effect of temperature and time. In the case of T-N, the optimal combination of 68 ° C and 4-hour points was analyzed. Significant correlation between temperature, time and time of time and time.
