| 摘 要： | 研究了采用前置反硝化曝气生物滤池工艺直接对生活污水进行处理,回流比对该工艺处理效果的影响。在一定范围内增大回流比有利于提高系统总脱氮率。根据试验结果,建议回流比选择2:1。在此条件下,COD去除率大于80%;NH4+-N去除率大于97%;总脱氮率大于75%。

| Abstract: | An experiment was carried out on domestic sewage using BAF with pre-denitrification process. The results show that reflux ratio on this system is significant. Within a certain range of increasing total nitrogen removal rate of the reflux ratio improves the system. According to the trial results, recommend that reflux ratio select 2：1. Under this condition, COD removal efficiency is greater than the 80%;NH4＋-N removal efficiency greater than 97%; total nitrogen rate greater than 75%. |
