【摘要】 通过包埋固定化硝化菌颗粒和生物接触氧化法在不同温度条件下的硝化反应速率测定试验,发现在28℃时两个反应器均达到最大硝化速率,分别为40 mgN/(L.h)和31 mgN/(L.h);温度降至8℃时,硝化速率分别为18 mgN/(L.h)和8 mgN/(L.h),包埋固定化硝化菌在低温条件下显示出明显的优势。温度为20~32℃时,包埋硝化菌处理高氨氮废水很容易形成亚硝酸型硝化。更多还原

【Abstract】 The nitrification rates,measured under different temperatures through nitrification experiments by embedded nitrobacteria granular reactor and biological contact oxidation reactor,both reach maximum nitrification rates of 40?mg N/(L·h) and 31?mg N/(L·h) respectively at 28℃.When the temperature dropped to 8℃,the nitrification rates decrease to 18?mg N/(L·h) and 8?mg N/(L·h) respectively.The embedded nitrobacteria reactor has obvious advantages at low temperature.When the temperature is 20—32℃,nitrite oxidation can be easily achieved in the treatment of high concentration ammonia wastewater by the embedded nitrobacteria.更多还原
