摘　　要：自动加氯数学模型与加氯消毒理论相结合,对原有自动加氯工艺进行优化设计,改进国内加氯消毒控制模式,以出厂水余氯(一氯胺)目标值来自动控制整个工艺过程的加氯、加氨量;以滤后一氯胺和游离氨作为工艺控制参数,来监控出厂水的总氯和总氨值,使加氯和加氨量达到最小化,降低药耗,减少消毒副产物。Optimization of the original automatic chlorination disinfection process was carried out by combining the mathematical model of the automatic chlorination with chlorination theory. The entire disinfection process of chlorine and ammonia dosing was auto- matically controlled by the target value of finished water residual chlorine （monochloramine）. The total chlorine and total ammonia of the finished water were monitored by the filtered water monochloramine and free ammonia as process control parameter. As a result, chlorine and ammonia dosage were minimized, the chemical consumption and the disinfection by-products were reduced.
