浅谈小型城镇污水处理厂工艺运行控制

On the Small Town Sewage Treatment Plant Process Operation Control

以四川某小型污水处理厂为例,介绍了该污水处理厂的工艺运行控制方式。通过探讨运行过程中的溶解氧、污泥浓度、泥龄以及回流比等主要参数的确定方式以及分析运行以来出现的一些问题及其解决办法,总结出了小型城镇污水处理厂实际运行中的一些运行经验及控制方式,对同类污水处理厂具有借鉴及参考作用。

A small sewage treatment plant in Sichuan as an example, the paper introduces the process operation control mode of the sewage treatment plant. By discussing the dissolved oxygen, the sludge concentration, sludge age and the determination of main parameters such as reflux ratio in the process of operation as well as the analysis run since some of the problems and their solutions, summarizes some operation experience in small town wastewater treatment plant operation and control mode, it has reference and reference function to deal with the similar wastewater treatment plant.
