BASIN FOR THE TREATMENT OF WASTE WATER BY BEDS WITH MACROPHYTES.

摘要

Wastewater treatment pond comprising a plurality of treatment tanks per macrophyte bed. Each bin comprises a first set of wastewater distribution pipes (22, 24) located above the tank for distributing the wastewater above the tank and a first set of draining pipes for treated water (26, 28, 30). located at the bottom of the tank to recover the purified water, and a second set of wastewater distribution pipes (32) located under the surface of the macrophyte bed upstream of the tank to distribute the wastewater in the tank and a second set of drainage pipes purified water (34) located at the bottom of the tank downstream thereof to recover the purified water. Valves (36, 38, 40, 42, 44, 52, 56) allow either to connect the wastewater inlet to the first set of distribution pipes and to connect the outlet of the treated water to the first set of drainage pipes when the The tank operates as a vertical filter, connecting the wastewater inlet to the second set of distribution pipes and connecting the outlet of the treated water to the second set of drainage pipes when the tank operates as a horizontal filter.
