基于有机废水作为碳源补充的改良型A2/O工艺污染物去除效果研究
|
Abstract:
本研究采用改良型A2/O工艺，结合进水碳源和出水总氮，采取多段进水方式，保证厌氧释磷和缺氧区的反硝化良好进行，确定生化池运行的最佳内回流比为前缺氧区回流比100%，后缺氧区回流比200%。高浓度可生化有机废水作为碳源投加时，改良型A2/O工艺出水效果较稳定。
This study adopted an improved A2/O system, combined with influent carbon source and effluent total nitrogen, and adopted a multi-stage influent method to ensure good anaerobic phosphorus release and denitrification in the anoxic zone. The optimal internal reflux ratio for the operation of the biochemical tank was determined to be 100% in the front anoxic zone and 200% in the back anoxic zone. When high concentration biodegradable organic wastewater was added as a carbon source, the improved A2/O system has a relatively stable effluent effect.
