深床反硝化滤池工艺技术在污水处理厂的提标试验研究

Study on the Extraction of Deep Bed Denitrifying Filter Technology in Sewage Treatment Plant

深床反硝化滤池工艺是一种集生物脱氮和过滤功能于一体的处理单元,本文通过试验对该工艺进行了深入研究。试验结果表明,深床反硝化滤池工艺可以广泛应用于污水处理厂的提标改造中,效果稳定性好,脱氮去除率最高可达90%,总氮、总磷、悬浮物等出水指标可稳定达标。传统提标改造工艺往往占地面积大,运行费用高,建设周期长,工艺管道复杂,与之相比,该工艺具有明显的技术优势。

Deep bed denitrification filter is a processing unit of biological nitrogen removal and filtration. This process is studied in this paper. The experimental results show that the deep bed denitrifying filter process can be widely applied to the upgrading of sewage treatment plants. The effect is stable, and the removal rate of nitrogen is up to 90%. Total nitrogen, total phosphorus and suspended matter can be stable. The traditional upgrading technology often has large area, high operation cost, long construction cycle and complex process pipeline. Compared with the traditional technology, the technology has obvious technical advantages.
