PURPOSE:To obtain a constant flow rate without chocking by installing a weir in a floating box on liquid and allowing the liquid to overflow the weir. CONSTITUTION:The floating type quantitative liquid supplying device provided with one hollow float 2 at every corner of a floating box 1 is floated in a sediment separation tank, and sewage water is supplied from the sediment separation tank to a rotating disk tank. The weir 3 is installed in the floating box 1 and the liquid flowing from an intake pipe 5 to a weir upper stream 1a overflows the weir 3 to flow out of an outlet pipe 7, and is sent out of the tank through an outlet nozzle 8. The liquid level of the tank 4 and the weir 3 in the floating box 1 are in constant relation, so the quantity of the liquid overflowing the weir 3 is held constant even when the liquid level of the tank 4 fluctuates. |
