| 摘 要： | 研究了以聚乙烯醇(PVA)为骨架载体,添加适量的添加剂,利用活性炭吸附硝化细菌,采用包埋法制作固定硝化细菌小球,去除水体中氨氮的方法.通过实验,发现1%的海藻酸钠(占PVA的凝胶百分比),4%SiO2,0.3?CO3作为添加剂,PVA包埋硝化细菌的成球效果较好,小球表现有较佳的机械强度以及传质性能.同时用正交实验确定了在PVA质量浓度为10%,活性炭含量占PVA凝胶的2%,交联时间32h及包菌量的值为1∶2的情况下,包埋的固定化小球去除氨氮的效率最高,42 h就可以达到80%以上,去除氨氮效率强. |

| Abstract: | A technics used to efficiently remove NH~ _4-N in the water treatment is studied with the carrier of PVA entrapping nitrobacteria in this paper.It is reported that 1% sodium alginate,4% SiO_2,0.3% CaCO_3 are the good additives for PVA beads immobilized nitrifying bacteria by PVA crosslinked with boric acid.The beads have well mechanical intensity and diffusion characteristics.At the same time the NH~ _4-N removal efficiency is very high with these beads which are made under the conditions of 10% PVA,2% active carbon,32?h crosslinked time and 1 vol.nitrifying bacteria in 2 vol.gelatin.The NH~ _4-N removal efficiency could reach 80% or more in 42?h.The effect is remarkable. |
| Keywords: | immobilized microorganism entrapment nitrifying bacteria NH_4~ -N polyvinyl alcohol(PVA) |
