SYSTEM FOR RECYCLING WASTEWATER RESULTING FROM THE WASHING AND RINSING PROCESS OF A DISHWASHER, ESPECIALLY FOR REUSE IN SAID PROCESS AND FOR IRRIGATION OF PLANTS, AND PROCESS FOR THE USE OF SAID SYSTEM

A system for recycling wastewater resulting from the washing and rinsing process of a dishwasher (1) is described, said dishwasher having at least one washing cycle and at least one rinsing cycle, the system comprising: - a plant irrigation system (7) comprising a collection system (8) for collecting drainage irrigation liquid coming from the irrigation system; - a first reservoir (2) adapted to receive and contain liquid drained from the dishwasher as a result of said washing and rinsing cycles and liquid coming from said collection system (8); - a second reservoir (3) adapted to receive and contain a liquid; - a first filter (4) adapted to filter a liquid coming from said first reservoir (2); - a biological filter (5) adapted to further filter the liquid coming from said first filter (4), said biological filter being adapted to transform an organic component of the liquid received from said first filter into an inorganic component, comprising nutritious substances for said plants; - a first pumping device (6) adapted to supply the liquid coming out of said biological filter (5) to said plant irrigation system (7) or, if not required by said irrigation system, to said second reservoir (3); - a second filter (9) and a second pumping device (10) respectively adapted to filter and supply liquid contained in said second reservoir (3) to a washing water inlet (I) of said dishwasher (1) as a partial or total replacement for water coming from an external water supply network (E), for supplying water to the dishwasher. L'invention concerne un système de recyclage des eaux usées résultant du processus de lavage et de rinçage d'un lave-vaisselle (1), ledit lave-vaisselle comportant au moins un cycle de lavage et au moins un cycle de rinçage, le système comprenant : un système d'irrigation de plante (7) composé d'un système de collecte (8) servant à collecter un liquide d'irrigation de drainage provenant du système d'irrigation ; un premier réservoir (2) conçu pour recevoir et contenir le liquide évacué du lave-vaisselle résultant desdits cycles de lavage et de rinçage, et le liquide provenant dudit système de collecte (8) ; un second réservoir (3) conçu pour recevoir et contenir un liquide ; un premier filtre (4) conçu pour filtrer un liquide provenant dudit premier réservoir (2) ; un filtre biologique (5) conçu pour filtrer davantage le liquide provenant dudit premier filtre (4), ledit filtre biologique étant conçu pour transformer un composant organique du liquid
