- 摘要:
- 基于上海某污水处理厂的生产性试验装置,研究了污泥龄(SRT)对两级生物选择反硝化除磷脱氮(BBSNP)工艺反硝化除磷效能的影响。结果表明,SRT对BBSNP工艺的反硝化除磷效能有着较大的影响。当将SRT从7 d提高到15 d时,厌氧区的COD去除率由62.37%提高到80.32%;缺氧吸磷率均值由33.9%提高到77.9%,厌氧释磷倍数由3.11倍提高到4.13倍;总氮去除率由68.27%提高到74.05%,这表明系统内富集了大量的反硝化聚磷菌,表现出良好的反硝化除磷效果,提高了出水水质。
- Abstract:
- Effect of sludge retention time (SRT) on the nitrogen and phosphorus removal efficiency of the bi-bio-selector for nitrogen and phosphorus removal (BBSNP)process was explored based on full-scale test device in a municipal sewage treatment plant in Shanghai. The results showed that SRT had a great influence on nitrogen and phosphorus removal efficiency of the BBSNP process. After increasing the SRT from 7 days to 15 days, COD removal efficiency in the anaerobic tank increased from 62.37% to 80.32%, the anoxic phosphorus uptake rate increased from the average of 33.9% to 77.9%, the anaerobic phosphorus release time increased from 3.11 times to 4.13 times, and the total nitrogen removal efficiency increased from 68.27% to 74.05%. This indicated that a large number of denitrifying phosphorus accumulating bacteria were enriched in the system, which showed a good removal effect of nitrogen and phosphorus and improved the effluent quality.
