| 摘 要： | 通过使用硝化细菌增养液挂膜，用生物接触氧化法对生活污水处理厂出水以及富营养化河水中的氨氮进行了处理。试验结果表明：在很短的水力停留时间条件下（１ｈ），污水厂出水经处理后ＮＨ３－Ｎ全部达标并小于８ｍｇ／Ｌ，其去除率达７０％；ＮＯ＾－２－Ｎ小于４ｍｇ／Ｌ。富营养化河水在ＨＲＴ为１．２ｈ时，出水ＮＨ３－Ｎ与ＮＯ＾－２均小于１ｍｇ／Ｌ。试验出水中的氮主要以ＮＯ＾－３－Ｎ的形式存在。

| Abstract: | Through using the nitrifying bacteria to make fixed film, this experiment used biological contact-oxidation to treat the effluent of domestic wastewater treatment plant and NH3-N in the eutrophication river water. The results indicated that under a short HRT condition (1h), NH3-N in the effluent could meet the standard, and the value was below 8mg/l. after treatment. The removal efficiency reached 70% and the value of NO2-N was below 4mg/l. When the HRT was 1.2h, both NH3-N and NO2-N in the effluent of eutrophication river water were below 1mg/l, and the main form of N was NO3--N. |
