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%CaCO3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% SiO2

0.3% CaCO3 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.
