 Abstract:

Leachates and domestic wastewater constitute a real problem for the environment, given their risks to surface water, groundwater, and the surrounding soil. Their management becomes delicate because of the demographic growth, and the standard of living of the population. Due to the reduction of water resources in the world, their treatment is very essential. In this study, samples of young raw leachate were collected and mixed with domestic wastewater. After a physicochemical and bacteriological characterization of leachate, domestic wastewater, and the mixture M1 (leachate ratios of 5%), an aerated biological treatment was carried out without adding activated sludge. Over a residence time period of six weeks, the chemical oxygen demand reduction rate reached 94.8% for the wastewater, 93.8% for the M1 mixture, and only 31.9% for the leachate. The addition of 5% young leachate to domestic wastewater does not affect the aerated biological treatment system, in addition, it is an inexpensive system.
