Document Type and Number:
WIPO Patent Application WO/2019/106927
Kind Code:
A1
Abstract:
A drainage circulation system 100 is provided with: a tank 2; a pressure-feeding mechanism 5 that pressure-feeds drainage in the tank 2; a switching valve 51a that switches the supply destination of drainage pressure-fed from the pressure-feeding mechanism 5 between a boiler 61 that is the normal supply destination and an intermediate tank 62 separate from the boiler 61; a water quality sensor 3 that detects the water quality of drainage; a washing part 4 that supplies washing liquid to the tank 2; and a control unit 7. If the water quality satisfies a water quality criterion, the control unit 7 controls the switching valve 51a to set the supply destination of drainage to the boiler 61. If the water quality of drainage does not satisfy the water quality criterion, the control unit 7 controls the switching valve 51a to set the supply destination of drainage to the intermediate tank 62 and causes the washing part 4 to supply the washing liquid to the tank 2.
