青岛市某污水厂ICEAS工艺升级改造工艺选择与分析

Selection and Analysis of Upgrading Reconstruction Project in a Qingdao WWTP

在青岛某城市污水处理厂ICEAS工艺升级改造工程设计中,分析了现有污水处理技术条件、存在的问题与目标差距,通过多种技术方案的比较分析,确定以ICEAS/MBBR为主体的二级生化处理与活性砂过滤深度处理改造方案,同时针对目前曝气系统存在的问题提出了AVS解决方案。

As the national and local governments attach importance to water environment protection more and more seriously and the discharge standards for WWTPs are much na are facing urgent need for upgrading reconstruction. Taking a WWTP in stricter, most WWTPs in Chi- Qingdao City as an example, based on the analysis of existing technical conditions, problems and goal gaps, ICEAS ＋ MBBR biochemi- cal treatment process and active sand filtration are determined by means of various technology options. Meanwhile, AVS aeration control system is adopted to solve the problem of uneven air distribution.
