UNKNOWN WATER VOLUME PREDICTION DEVICE AND UNKNOWN WATER VOLUME PREDICTION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an unknown water volume prediction device and an unknown water volume prediction system, allowing a sewage treatment plant to easily respond to sewage including unknown water.;SOLUTION: The unknown water prediction system 1 includes a rainfall radar 2, a rainfall information processor 3, a sewage volume measuring device 4, an unknown water volume calculation device 5, and an unknown water volume prediction device 6. The unknown water volume prediction device 6 calculates an unknown water volume Qu flowing into the sewage treatment plant 52 by substituting the rainfalls r₁-r_n at a plurality of points of a treatment object area 61 and an unknown water volume Qr to an unknown water volume prediction expression (1) calculated by performing main component analysis.;COPYRIGHT: (C)2010,JPO&INPIT
