在以地面水为水源的给水处理过程中,投加混凝剂是极其重要的一个环节。如何实现这一环节的自动控制,一直是同行们非常关注的课题之一。传统的投药自动控制技术,一是采用数学模型法,二是采用(浊度)负反馈的方法,但它们都存在较大的弊端。前者难以建立准确的数学模型和需要大量 In the surface water as the source of water treatment process, adding coagulant is an extremely important part. How to achieve this part of the automatic control, has been one of the topics of great concern to colleagues. The traditional automatic drug control technology, one is the use of mathematical modeling, and the other is the use of (turbidity) negative feedback method, but they all have larger drawbacks. The former is difficult to establish an accurate mathematical model and requires a lot
