摘要/Abstract

摘要： 针对引发丝状菌污泥膨胀的因素较多且其机理模型难以表达的问题，从丝状菌生长动力学角度提出了一种污泥体积指数（SVI）简化机理模型。首先，通过研究丝状菌污泥膨胀的形成过程，分析引发丝状菌污泥膨胀的影响因素，获得了影响因素与SVI之间的关系；其次，确定影响SVI的主要因素，设计出SVI的简化机理模型，并利用数据分析和统计方法校正了模型中的参数；最后，将该简化模型应用于实际污水处理厂，实验结果显示该模型能够较好地反映丝状菌污泥膨胀发生过程，获得较高的SVI预测精度。

Abstract: Owning to the large amounts of factors for causing filamentous bulking sludge and many troubles in expressing its mechanistic model of causing filamentous sludge bulking,a simplified mechanistic model is proposed for sludge volume index (SVI) from the filamentous bacteria growth kinetics in this paper.First,the appearance of filamentous sludge bulking is studied.And then the relationships among the SVI and the impact factors are obtained by analyzing the filamentous sludge bulking process.Secondly,the main factors for SVI are ensured.The simplified mechanistic model of SVI is designed.Meanwhile,the parameters of this proposed model are adjusted by using the method of data analysis and statistics.Finally,this simplified mechanism model is used for a real wastewater treatment process.The results show that this proposed model can simulate the mechanistic of filamentous sludge bulking and predict SVI accurately.
