| 摘 要： | 为强化CASS工艺脱氮除磷效果,提出FND-CASS工艺。FND-CASS工艺与CASS工艺的对比试验结果表明:FND-CASS工艺在有机污染物去除和氨氮的硝化方面能力略有下降,但是在脱氮除磷方面,在节省耗氧量的前提下具有明显的优势。在同样的进水流量且DO浓度控制较低的运行条件下,FND-CASS工艺的TN去除率达到80.52%,TP去除率达到80.44%,而通常的CASS工艺的TN和TP的去除率仅分别为73.51%和67.00%。

| Abstract: | In order to intensify the effect of nitrogen and phosphorus removal under CASS, the technique of FND - CASS isputs forwarded. The contrastive experiments among FND - CASS and CASS process have been performed. The results show thatthe FND - CASS process is lower than the CASS process in organic substance removal and ammonia nitrification, but it is advanta-geous in nitrogen and phosphorus removal. Under the same condition of inflow and lower DO concentration, the ratios of nitrogenremoval and phosphorus removal by the FND - CASS process are 80. 52% and 80. 44% respectively, by the CASS process are only 73.51% and 67% respectively. |
