Document Type and Number:
WIPO Patent Application WO/2017/098941
Kind Code:
A1
Abstract:
This biological treatment device (10) comprises: a biological treatment water tank (11) in which an organic substance included in water to be treated (W1) is treated; a membrane separation device (13) including a casing, and a tubular filter membrane that has a single-layer structure made by copolymerizing hydrophilic monomers and that partitions the casing into a concentrated-side space to which outflow water (W2) flowing out from the biological treatment water tank (11) is supplied and a permeation-side space in which permeated water separated from the outflow water is housed; a pressurizing pump (21) that pressurizes the outflow water (W2) and supplies the same to the concentrated-side space; a suction pump (22) that sucks the permeated water from the permeation-side space; a pressure gauge (23) that measures the pressure of the permeation-side space; a return line (19) that returns concentrated water (W3) to the biological treatment water tank (11); and a control device (12) that controls the amount of said outflow water (W2) supplied by the pressurizing pump (21) on the basis of the measurement value of the pressure gauge (23).
