【摘要】：采用琼脂、海藻酸钠、聚丙烯酰胺3种包埋方法制备出硝化细菌污泥固定小球,考察了成球的难易及其物理机械性能,并采用制备小球进行氨氮的降解实验。结果表明,3种固定化小球对氨氮的转化均有明显活性,琼脂固定化小球的活性最好,保存时间长,但成球较困难,聚丙烯酰胺成球容易而活性相对偏低,相比之下,海藻酸钠固定化小球的活性较高且易成球,具有较好的应用前景。
[Abstract]:Nitrifying bacteria sludge immobilized pellets were prepared by three kinds of embedding methods: Agar, sodium alginate and polyacrylamide. The difficulties and physical and mechanical properties of the pellets were investigated, and the ammonia-nitrogen degradation experiments were carried out with the prepared pellets. The results showed that the three immobilized pellets had obvious activity in the conversion of ammonia nitrogen. Agar immobilized pellets had the best activity and long storage time, but it was difficult to form the pellets. The activity of polyacrylamide pellets was relatively low, compared with that of the Agar immobilized pellets. Sodium alginate immobilized pellets have high activity and are easy to be formed, so they have a good prospect of application.
