摘　　要：针对污水处理过程的污泥膨胀难以精准识别的问题,提出了一种基于自适应宽度学习算法(adaptive broad learning algorithm,ABLA)的污泥膨胀识别方法。首先,结合城市污水处理过程的运行数据,采用主元分析法选取与污泥体积指数(sludge volume index,SVI)相关的特征变量;其次,建立了一种基于ABLA的污泥膨胀识别模型,利用自适应伪逆算法更新模型参数,提高了识别精度,并验证了模型的收敛性;最后,将所提模型应用于实际的污水处理过程中,利用污水处理厂的实际运行数据对其进行实验验证。实验结果表明,基于ABLA的污泥膨胀识别模型能够实现污泥膨胀的精准识别。A sludge bulking identification method based on adaptive broad learning algorithm(ABLA)is proposed to solve the problem of accurate identification of sludge bulking in wastewater treatment process.Firstly,based on the data collected from municipal wastewater treatment process,the principal component analysis method is used to select the characteristic variables which have the correlation with sludge volume index(SVI).Secondly,a sludge bulking identification model based on ABLA is established,and adaptive pseudo-inverse algorithm is used to update the parameters of the model to improve the identification accuracy.The model convergence is proved.Finally,the proposed model is applied to the actual wastewater treatment process,and the actual operation data of the sewage treatment plant is used to verify the model.The experimental results demonstrate that the sludge bulking identification model based on ABLA can realize the accurate identification of sludge bulking.
