不同条件对高效菌去除污水中氨氮效果影响研究

本文研究了pH值、温度、曝气时间、茵投入量（体积比）、溶解氧、水力停留时间、进水碳氮比、冲击负荷等影响因素对氨氮去除率的影响，对项目参数进行了优化。研究结果如下：在高效菌处理氨氮废水时，为了得到较好的去除效果，pH值应控制在7．0到8．O之间；温度应控制在25℃到35℃之间；曝气时间应保持在5h到6h之间；茵投入量（体积比）应保持在0．004到0．006之间；溶解氧浓度应保持在2mg／L到3mg／L之间：水力停留时间为16h．高效茵对污水中氨氮的去除效果最佳。

The study of the impact of removal ammonia in sewage by efficient bacteria under different conditions

This paper studies the fect of dissolved oxygen,hydrauli pH value, temperature, aeration time, bacteria quantity （volume ratio）, the ef- c retention time,influent factors of carbon nitrogen ratio,the impact load on the removal rate of ammonia nitrogen ,the project parameters were optimized.The results are as follows：in high efficient bacteria treatment of ammonia nitrogen wastewater,in order to get a better removal effect,pH value should be controlled between 7 to 8;temperature should be controlled at 25℃ to 35℃ ;aeration time should be kept between 5 h to 6 h ;bacteria amount （volume ratio） should be kept between 0.004 to 0.006;dissolved oxy- gen concentration should be maintained at 2mg/L to 3mg/L;hydraulic retention time is 16h,high efficient bac- teria in sewage ammonia nitrogen removal effect is best.
