  In this research, in order to use the effluent from the Dezful sewage treatment plant in the industry and agriculture sector, some quality parameters of the treatment were evaluated according to the quality guidelines of the Environmental Organization, since the aeration time is the longest in the sewage treatment plant with aeration lagoon system without sludge return. It has an effect on the process of biological activities. Therefore, in this research, the changes of do and the removal efficiency of the quality parameter cod were investigated at 4, 5, and 7-hour operating times, and the best aeration time for the lagoons was selected. تفاصيل المقالة
