Abstract (en)
[origin: WO2006128994A2] 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.
