Abstract

Background: Good water quality is crucial to human health, social and economic development as well as the functioning of ecosystems. Economic activities, unabated population growth and unsustainable farming practices further increase pressures on water bodies. Objective: The present study relates to the evaluation of the efficiency of the treatment of waste water from the Khenifra sewage treatment plant of the bacterial bed type during the period of 2019. Methods: In our work we studied the physico-chemical parameters of the raw and purified waste water from the station. For this, we have carried out a set of measurements such as: temperature, pH, electrical conductivity, biochemical oxygen demand BOD5,chemical oxygen demand COD, suspended matter MES. Results: The COD/BOD5 ratio determines the possibility of degradation that can be hoped for by a biological oxidation treatment. The values obtained are an average of 1.09.And the average MES/BOD5 ratio of 0.9 to 2013 and 1.04 to2014. Conclusion: This allows us to deduce that the load of organic matter in wastewater within the ship repair units is easily biodegradable.
