本文以中小型污水处理厂为例,对自动化仪表控制系统在污水处理中的应用作以介绍。一、工艺流程从图1可见将污水送入帘格井中,这时许多污水中大砂粒、铁屑等物质被筛出。污水进入泵房,泵房作临时储备室。用水泵将污水抽入曝气沉砂池中,通过鼓风机房将空气吹入污水中,污水中的大部分微小砂粒受重力作用开始脱离污水。当污水进行初次沉淀时,微小砂粒集中于池底部,在池底部装有沉砂积泥处理
In this paper, small and medium-sized sewage treatment plant, for example, the automation instrumentation control system in the sewage treatment applications are introduced. First, the process can be seen from Figure 1 Sewage into the grid wells, then many of the sewage in the sand, iron and other substances are screened. Sewage into the pump room, pump room for temporary reserve room. The pump is used to pump the sewage into the aeration grit chamber. The air is blown into the sewage through the blower room. Most of the tiny sand in the sewage starts to separate from the sewage by gravity. When the primary sedimentation of sewage, tiny sand concentrated in the bottom of the pool, at the bottom of the pool filled with sediment sediment treatment
