Water treatment system, water treatment method, and recording medium

A wastewater treatment system includes a plurality of reaction tanks, a blowing pipe, a blower unit, and an air supply amount controller. The air supply amount controller includes: a water quality measurement unit configured to measure a state of wastewater; a necessary air amount acquisition unit configured to acquire, a necessary air amount for achieving a predetermined target water quality of wastewater; a target in-pipe pressure calculation unit configured to calculate a blowing pipe loss pressure when the necessary amount of air is supplied into the blowing pipe, calculate a target in-pipe pressure based on the blowing pipe loss pressure, and change the calculated target in-pipe pressure in accordance with change of the necessary air amount; and a blowing control unit configured to control air supply from the blower unit so that the pressure in the blowing pipe becomes equal to the target in-pipe pressure.
