| 摘 要： | 以硝化菌增长的Ｈａｌｄａｎｅ模式为基础，通过理论分析证明，完全混合式活性污泥反应器是碳氧化（ＣＯＤ降解）和ＮＨ３—Ｎ硝化合并处理工艺的最佳反应器，给出了曝气池ＮＨ３—Ｎ的最佳浓度（７．４ｍｇ／Ｌ）．在此基础上，采用单级活性污泥法处理同时含有ＣＯＤ３５０—４００ｍｇ几和ＮＨ３—Ｎ１５０ｍｇ／Ｌ的树脂生产废水，结果表明：当控制水力停留时间（ＨＲＴ）为８ｈ时，ＮＨ３—Ｎ的硝化率和ＣＯＤ去除率分别为９０％和６５％，将ＨＲＴ延长至１０ｈ，ＮＨ３—Ｎ可完全硝化，而ＣＯＤ的去除率并不降低。

| Abstract: | On the basis of Haldane nitrifier growth model,it is confirmed theoritically that the completely-mixed activated sludge reactor can be the optimum one for simultaneous carbonaceous oxidation (COD degradation ) and ammonium nitrification. The optimum NH3-N concentration (7.4 mg/L) in the aeration tank is also given. A laboratory scale experiment using synthetic resin production wastewater which 350-400 mg/L COD and 180 mg/L NH3-N are contained is conducted. The results show that ammonium nitrification rate and COD removal efficiency can reach 90% and 65% respectively, in a single activated sludge process when hydraulic retention time (HRT) is controlled at 8h. Ammonium can be completely nitrified with HRT 10h. whereas COD removal efficiency can be maintained unchanging. |
