Title:
AEROBIC ORGANISM TREATMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/163423
Kind Code:
A1
Abstract:
An aerobic organism treatment device 1 has: a reaction tank (tank body) 2; a water-permeable plate 3 arranged horizontally at the bottom of the reaction tank 2; a large-diameter particle layer 4 formed on the upper side of the water-permeable plate 3; a small-diameter particle layer 5 formed on the upper side of the large-diameter particle layer 4; an oxygen dissolution film module 6 disposed on the upper side of the small-diameter particle layer 4; a receiving chamber 7 formed on the lower side of the water-permeable plate 3; a raw water dispersion tube 8 that supplies raw water into the receiving chamber 7; an air-diffusing tube 9 arranged so as to diffuse air inside the receiving chamber 7; etc. When the pH inside the reaction tank 2 declines, air is diffused from the air-diffusing tube 9 and decarboxylated, and the pH inside the reaction tank 1 is raised.
