The raw wastewater at the entrance to the station complies with the characteristics of domestic wastewater for large cities (BOD5 =357.18 mg/l; COD=698.58 mg/l and suspended matter SM=493.14 mg/l).
The results of the physicochemical analysis of the sewage into and out show that: *Most of the parameters studied respond well to the expected treatment plant wastewater Oujda by aerated lagoon such as pH, temperature, dissolved oxygen, conductivity, BOD5 and suspended matter SM;
* The rate of reduction of BOD5, COD and SM are 84 %, 85 % and 80% respectively;
These values are below the limit values that are 2, indicating that the effluent to be treated is a domestic wastewater therefore biodegradable kind. Thus the system of wastewater Oujda aerated lagoon waters is well suited for this type of effluent. Keyphrases: Biodegradability, Morocco, Oujda, WWTP, aerated lagoons, physico-chemical, wastewaters
