Title:
ORGANIC WASTEWATER TREATMENT METHOD AND TREATMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/042550
Kind Code:
A1
Abstract:
Provided is an organic wastewater treatment method in an organic wastewater treatment device. The organic wastewater treatment device comprises: a reaction tank in which a biological treatment is performed on a pollutant that is contained in organic wastewater; a solid-liquid separation device which separates sludge from wastewater that has been discharged from the reaction tank; and a feeder which feeds at least oxygen to the reaction tank. The reaction tank has a tubular membrane carrier that causes molecular diffusion, in the reaction tank via a plurality of holes, of oxygen which has been fed by the feeder. The membrane carrier causes the molecular diffusion of the oxygen in the reaction tank via the plurality of holes so as to form a biological membrane that contains aerobic bacteria on the outer circumference of the membrane carrier. The biological membrane subjects the pollutant to a biological treatment via the aerobic bacteria. The solid-liquid separation device separates sludge containing the biological membrane from the wastewater.
