Patent number: 8196596Abstract: A method for tracking a pollution source in process water is presented. Firstly, variation curves of drain water drained from different rinsing tanks are respectively obtained, and a water quality concentration of the drain water drained to a buffer tank is detected, so as to output a water quality variation curve.
