The invention relates to a method for processing nitrogen-concentrated effluents by ammonia oxidation into nitrites followed by nitrite denitritation in a gaseous nitrogen in a sequential biological reactor (1) consisting in pouring a processable effluent volume in to the reactor by successive volume fractions, in dividing the entire processing cycle into successive sub-cycles, wherein each sub-cycle comprises a feeding phase, an aeration phase for nitrification and an anoxia phase along which a carbon-containing source is introduced into the reactor for converting nitrites into nitrogen. The inventive method also consists in evaluating a nitrogenous volume charge in the effluent to be processed, mainly by measuring the effluent conductivity (X) and the flow rate (Q) and in determining the number of feeding phases of the entire cycle according to nitrogenous charge and to a minimum volume of liquid in the reactor in such a way that an injected nitrogen concentration is diluted in the liquid volume, wherein the volume phase nitrogenous charge is however sufficient for producing a single shot or peak of the ammonia charge favourable for a nitrating biomass formation in the reactor.
The invention concerns a method for treating effluents of communities equipped with a wastewater system capable of collecting rain or infiltration water, such that the flow rate of effluents to be treated by a treatment station may greatly vary between a dry weather period and a rainy weather period, whereby is provided a purification plant (1) of capacity substantially adapted to effluent flow rate in dry weather (Qs); upstream of the treatment plant, is provided a filter bed (12) with grown plants for stocking without fermenting, a polluted hydric excess, and for prior treatment; effluent excess (Qp) caused by rain or a storm is directed onto the filter bed (12) with grown plants; the water in stored in the filter bed (12) with grown plants is gradually evacuated to be sent to the treatment plant (1) located downstream.
