MONITORING METHOD AND SYSTEM OF TRIHALOMETHANE FORMATION POTENTIAL AND HALOACETIC ACIDS FORMATION POTENTIAL IN DRINKING WATER TREATMENT

摘要

A method for monitoring trihalomethane formation potential and haloacetic acids formation potential is provided to improve safety of final processed water by controlling and detecting generation of disinfection byproducts. A method for monitoring trihalomethane formation potential and haloacetic acids formation potential comprises the following steps of: measuring concentration of residual chlorine in processing water, contacting time of chlorine and water temperature, etc(210); calculating and outputting trihalomethan formation potential and haloacetic acids formation potential from measured values(230); calculating differences between a potential value and predetermined reference values(240); generating an alarm signal in case the deviation exceeds the reference value(250); controlling the amount of chlorine injected into chlorination unit according to the signal(260); and outputting the performance as data to outside(270).
