塔式生物滤池处理城市污水的研究

尽管目前塔式生物滤池在城市污水处理中运用较少 ,但在有可资利用的地形时它可达到少动力或无动力运行 ,有较大的优势。研究了塔式生物滤池的工作参数及其处理特点。

Study on Municipal Wastewater Treatment by Biotower

By controlling the SBR reactor under aerobic condition, investigations were made into the effect of the ratio of influent carbon to nitrogen on nitrogen removal and simultaneous nitrification and denitrification (SND). In addition, the mechanism of SND was explored tentatively. It was found that a higher ratio of influent carbon to nitrogen could produce higher total nitrogen removal efficiency. Conclusion was drawn from the experimental results that there might coexist heterotrophic nitrifiers and aerobic denitrifiers inside the activated sludge flocs.
