Abstract

The objective of this work is to evaluate the performance of the treatment and purification station (WWTP) of the city of AïnTaoujdate, natural lagoon type. For this, we carried out a set of monthly measurements during the year 2018 of physicochemical parameters: temperature, pH, conductivity, dissolved dioxygen, biochemical oxygen demand (BOD5), chemical oxygen demand (COD) and suspended solids (SS). The results obtained show that: - the average flow is greater than the nominal design flow of the station; - Wastewater, treated in the treatment plant in the city of AïnTaoujdate, contains a large polluting load; - the average pollution abatement yields are 44.71% for suspended solids, 51.59% for COD and 49.01% for BOD5. Thus, the treatment of wastewater in the AïnTaoujdate WWTP is insufficient to lower pollutant concentrations and reduce the health risk to an acceptable level.
