| 摘 要： | 为控制水体富营养化 ,城市污水处理厂采用生物除磷脱氮工艺 ,因此在某些处理单元中有富磷液流产生。根据乌粪石生成的原理 ,在富磷液流中投加镁源 ,并调节pH为 8 5～ 9 0时 ,即能以乌粪石形式回收磷以补充日益短缺的磷资源。

| Abstract: | The process of biodephosphorization and biodenitrification is used for urban sewage treatment plants in order to control eutrophication of water body.Therefore,phosphorus-entriched liquid will be produced in some of the treating units.According to the principle of forming guano,magnesium source can be added to the phosphorus-enriched liquid with its pH regulated to 8.5～9.0,thus phosphorus can be recovered in the form of guano. |

| Keywords: | phosphorus-recovering sewage treatment plant and guano |
