Abstract
PURPOSE: To efficiently nitrify and denitrify secondarily-treated waste water, by detecting the pH level in a nitrification tank to adjust the pH level and detecting the dissolved oxygen level in the nitrified water to adjust the amount of added organic carbon source required for the denitrification.
