二沉池一维模型的不确定性分析

Uncertainty Analysis of One-Dimensional Model of Secondary Sedimentation Tank

在废水生物处理过程中,二沉池发挥着泥水分离和浓缩回流的重要作用。二沉池一维模型被广泛用于二沉池设计、管理和优化控制。本文对四种常用的二沉池一维模型在不同运行条件下的不确定性进行分析。研究发现,在雨天、污泥膨胀等条件下,二沉池模型的选择会对二沉池运行情况预测产生显著影响,选择不同的二沉池模型会导致运行控制策略不同。

In the biological treatment process of wastewater,the secondary sedimentation tank plays an important role in mud-water separation and concentration reflux.The one-dimensional model of secondary sedimentation tanks is widely used in their design,management,and optimization control.This paper analyzes the uncertainty of four commonly used one-dimensional models of secondary sedimentation tanks under different operating conditions.Research has found that under conditions such as rainy days and sludge expansion,the selection of secondary sedimentation tank models can have a significant impact on predicting the operation of the secondary sedimentation tank,and choosing different secondary sedimentation tank models can lead to different operation control strategies.
