摘要

为了探索微生物污垢的形成过程,在Kern-Seaton污垢模型的基础上,结合生长动力学模型建立了微生物污垢模型。以不锈钢光管内铁细菌微生物污垢的实验数据为依据,进行实验验证。结果表明:所建立的微生物污垢模型的计算数据与实验数据除诱导期外,相对误差在±20%以内。

Abstract

In order to establish a model which is suitable for describing the formation of microbial fouling,based on the Kern-Seaton fouling model,the microbial fouling model is established combined with the Kern-Seaton model in this paper.The correctness of this model is verified by the experimental data of iron bacteria in stainless steel tubes.The results show that computational data of the microbial fouling modelis in good agreement with the experimental data,the relative error is within ±20% except the period of induction.
