This aerobic waste pretreatment process comprises inoculating a milk industry effluent with a mixture of bacteria and yeasts both classes of microorganisms capable of living an growing in symbiosis in the effluent, the population of the bacteria being, in most cases, several times greater than the population of the yeasts, maintaining the temperature and pH of the inoculated effluent between 0 °C and 50 °C and between 1.7 and 9, aerating the effluent while varying, if necessary, the pH at maximum rate of 1.5 pH units per minute and also, if required, modulating the aeration of the inoculated effluent at a maximum rate of 130 micromoles of oxygen per minute. A biomass is obtained which has a good nutritional value suitable for animal feed.

L'invention concerne un procédé de prétraitement aérobie pour un effluent, consistant à inoculer à un effluent d'industrie laitière un mélange de bactéries et de levures, ces deux types de micro-organismes étant capables de vivre et de se développer en symbiose dans l'effluent, et le nombre de bactéries, dans la plupart des cas, étant supérieur de plusieurs fois à celui des levures. La température de l'effluent inoculé est maintenue entre 0 DEG C et 50 DEG C, et son pH entre 1,7 et 9. L'effluent est aéré et le pH peut varier par au maximum 1,5 unité de pH par minute, lorsque cela est nécessaire. Egalement, on peut varier l'aération de l'effluent inoculé par au maximum 130 millimoles d'oxygène par minute. La biomasse obtenue a une bonne valeur nutritive lorsqu'elle est utilisée comme aliment pour animaux.
