Research And Design Of Soft Measurement For Wastewater Toxicity And Monitoring System

Modern sewage treatment technology has been receiving increasing attention since Britain built the first modern sewage treatment plant in the industrial revolution. With large-scale sewage treatment plant of sewage treatment process complexity, and its monitoring system has also been a rapid development. Especially in recent years, with the industrial automation technology and computer network technology enables the rapid development of the corresponding sewage treatment monitoring technology changes have taken place in nature.Through analyzing sewage treatment process and sewage treatment plant design and planning, the system is analyzed the possibility of realizing. Proposed sewage treatment plant control system performance requirements. As Kingview good user interface, improved functionality and high cost, determined to develop software for the monitoring system.By analyzing the biochemical reaction mechanism, determine DO, COD, pH, and MLSS and biochemical parameters such as biochemical reactions closely related to the pool. By studying the secondary variable selection and data preprocessing methods, establish RBF neural network based on the biochemical pool of toxic sewage soft sensor model. Verified by simulation, achieved good results and met the requirements of online prediction. For building monitoring system and related applications, lay the foundation.The sewage treatment process had been analyzed in the text. These monitor pictures and the functions were designed according the request of the control system. The interface of monitoring system is visual, and easy to operation, provides a good monitoring. Monitoring system can display real-time data from the production process, and modify the parameters online according to the scene.This system has been running in long time, to prove its good stability. And it can improve water quality and energy saving effect.
