基于ELM网络的污水处理COD值预报模型研究

通过对沈阳某污水处理厂的叶轮气浮法污水工艺进行研究分析,得知其过程具有多变量、非线性和时变等特性,这些特性对于处理后水质的COD值准确检测非常重要。COD值的在线检测设备通常有一定滞后,影响了现场对水质的控制和提高,为此采用ELM网络来建立COD值的预报模型,并通过MATLAB软件进行了仿真研究,仿真结果表明该模型具有较好的预报效果。

Study on COD Forecast Model in Wastewater Treatment Based on ELM Network

Based on the study of a wastewater treatment plant using impeller flotation process in Shenyang,it found out the characteristics of multiple variables,non-linear and time variable,which were important to monitor COD in treated wastewater accurately.The online monitoring devices of COD generally have hysteresis quality,which will affect the control and the treated water quality.So,COD forecast model was built up by ELM network and simulated by MATLAB software.The simulation results showed that the model had good forecast effect.
