| 摘 要： | 为有效去除污水中的含氮物质 ,在体积为 3.5 L 的鼓泡曝气塔内使用模拟污水 ,研究了同时硝化和反硝化过程。实验过程中 ,在鼓泡曝气塔中投入占总体积 10 %的多孔聚氨酯载体 ,以实现微生物的固定化。实验表明 ,投加载体后 ,实验体系中含氮物质的去除效率明显提高 ;在 16～ 6 4L /h气体体积流量范围内可以在 3h内得到接近于 10 0 %的NH+ 4- N去除率 ;证明了采用补充碳源的方法可以有效提高NH+ 4- N去除率。

| Abstract: | This paper experimentally studies simultaneous nitrification and denitrification of wastewater in a 3.5 L bubble aeration column to develop an improved method for effectively removing. Porous carrier particles were added into the bubble aeration column to immobilize the microbes. The results show that adding porous carrier particles significantly increases the nitrogenous compounds removal rate. A nearly 100% removal ratio was achieved within 3 hours at air volumetric flow rates of 16~64 L/h. Adding a carbonaceous substrate during the aeration process also improves nitrogenous compound removal. |
