随着人们环保意识的加强以及国家对化工企业三废排放的严格要求，化工企业的工业废水必须经过严格处理才能排放。为了提高对废水处理的效率，针对流化造粒焚烧工艺的特点，我们为含氰废水处理装置设计出一套计算机控制系统。通过软件与硬件的完善相结合，成功实现了对含氰废水处理的自动控制。关键词：环保，废水，焚烧，自控Abstract：As the strengthen of people’s environmental protection consciousness and the strict demand of the country to the chemical enterprise sewage discharge. The sewage of the chemical enterprise can be discharged only through strict processing. In order to enhance sewage’s processing efficiency, considering the technical character of the fluidization burning, we designed an automatic control system for the device of dealing with the sewage which contains cyanogens. Unified through perfect software and the hardware, have successfully implemented the automatic control of dealing with the sewage which contains cyanogens.Key words: Environmental protection, sewage, burning, automation control
