Abstract—To use wastewater for aggregating vast farm landsit is necessary to disinfect harmful pollutants in the wastewater.UV-H2O2 photoreactors are capable of degrading the recalcitrant pollutants and other conventional pollutants. The simulation of the reactor prior to its manufacturing can help the designer to obtain the main parameters of the reactor to meet the best disinfection performance of the reactor and the least energy consumption. Many researchers used one-dimensional models to predict the performance of the UV-H2O2 photoreactor. In this paper a simplified one-dimensional model for an annular UV-H2O2 reactor is presented and its performance is compared with a 2D model. In this one-dimensional model a plug like velocity profile is assumed for the wastewater flow and the point source summation (PSS) model is used to obtain the UV radiation field. The accuracy of the one-dimensional model is compared with the validated two-dimensional model. Obtained results show that in the investigated annular reactor the error of one dimensional model for hydroxyl radical is about 50% and the error of contaminant removal is about 10%.
