针对工业循环水系统存在既浪费水资源又污染环境的问题,设计了一种基于ARM的工业循环水极化控制系统.该系统由极化能量检测电路实时检测循环本水质参数,水质参数经STM32F103处理后输出的PWM极化能量控制信号,由极化能量输出电路合成、隔离、放大后驱动极化体,产生极化电场作用于循环水.实际应用表明,该系统可控制循环水系统在较高浓缩倍率下运行,代替了循环水系统的加药处理流程,达到了减少水资源消耗、有效防止污染水资源的目的.%In view of problems of water wasting and environment pollution existed in industrial circulating water system, a polarizing control system of industrial circulating water based on ARM was designed. The system uses polarizing energy detection circuit to real-timely detect water quality parameters of circulating water, then the parameters are processed by STM32F103 to get PWM polarizing energy control signal which is integrated, isolated and amplified by polarizing energy output circuit to drive polarizing body, so as to produce polarizing field to act on circulating water. The actual application showed that the system can control circulating water system running at high concentration rate, which replaces dosing treatment process of circulating water system and reaches goals of reducing water consumption and preventing water pollution.
