废水处理中pH值的PLC自动控制系统

摘要

The pH value automatic control is a key link in the treatment of industrial wastewater. Based on much literature review, a new PLC automatic control system, suitable for pH value control in the wastewater treatment, is developed with simple structure and good control effect, which offers a practical approach for pH value automatic control in the treatment of industrial wastewater.%pH值自动控制是工业废水处理过程中的关键环节.在查阅大量文献的基础上,研究出一套新的适于污水处理pH值控制的结构简单且控制效果良好的PLC自动控制系统,为工业废水处理的pH值自动控制提供了一条切实可行的途径.
