| 摘 要： | 针对低温条件对高盐废水氨氮处理效果的影响,分别采用MBR和A/O工艺进行试验研究.试验中主要选择快速降温和缓慢降温两种方式考察氨氮去除率随温度下降的变化趋势.试验结果表明:低温条件下,50%海水比例时,随着温度的降低,两种工艺氨氮去除率都呈明显下降趋势,快速降温比缓慢降温对处理效果的冲击更大.在相同温度变化情况下,MB...

| Abstract: | The MBR process and A/O process were applied to study the influence of low temperature on the ammonia nitrogen removal efficiency in the high salinity waste water.The chang rule of ammonia nitrogen removal rate with temperature drops was researched by two different ways from the fast to the slowly.The experimental results indicated that the ammonia nitrogen removal rate of two processes dropped obviously with 50% seawater proportion under low temperature condition.The removal efficiency in the fast way was ... |
