PROBLEM TO BE SOLVED: To provide a vacuum-type drainage collection system and a drainage collection method for collecting drainage without leakage, in an economically efficient way.SOLUTION: A vacuum-type drainage collection system is provided that includes: a plurality of liquid storage tanks for storing drainage; a vacuum station having a collection tank into which drainage from the plurality of liquid storage tanks is collected, and a vacuum generator that introduces a negative pressure in the collection tank; a communication passage connecting each of the liquid storage tanks with the collection tank; a plurality of remote-controlled valves disposed in correspondence with each of the plurality of liquid storage tanks, for opening/closing the communication passage; measurement means disposed in correspondence with each of the plurality of liquid storage tanks, for measuring a condition of each of the plurality of liquid storage tanks; and control means for the remote-controlled valve that remote-controls an operation of the plurality of remote-controlled valves. The control means for the remote-controlled valve is capable of determining priority regarding an order of operation of the plurality of remote-controlled valves on the basis of an output signal from the measurement means, and remote-controlling the plurality of remote-controlled valves according to the priority.SELECTED DRAWING: Figure 1 |
