中文摘要：采用实际分散型生活污水作为试验原水,对曝气生物滤池的降解规律进行了试验研究。结果表明,与传统的观点不同,曝气生物滤池在处理低浓度有机废水时并不发生严格的有机物与氨氮的分段去除现象,有机废水氨氮与有机质基本在同一区域内去除,滤料在10～40cm段的去除率增长速度最快,在70cm之后去除率的增长开始逐渐变缓。在进口段,由于有机质浓度高,供氧充足,有机质的去除率较高;由于异养菌和氨化菌的作用,氨氮浓度在进口段不但不减少,反有微小升高。

外文摘要：Experimental studies on degradation law of organic matter and ammonia nitrogen in biological aerated filter（BAF） for domestic sewage were carried out.The results show that the organic matter and ammonia nitrogen removal do not exhibit the strict zoned phenomenon for low concentration organic wastewater.The organic matter and ammonia nitrogen are nearly removed in the same filter layer which differs from the traditional viewpoint.The removal rate of organic matter is fastest in the filter layer from 10cm to 40cm.After 70cm from the inlet,the removal rate gradually slows down.In the entrance section,the organic matter removal rate is great due to the higher organic concentration and abundant oxygen,but in contrast the ammonia nitrogen concentration does not decrease,and slightly increase due to the effect of heterotroph and ammonifiers.
