摘要
固定化微生物小球对高浓度水胺硫磷的好氧降解有较好的耐受性。若进水的化学需氧量（ＣＯＤ（ｃｒ））为２１４５～１２５００ｍｇ／Ｌ，每隔４５ｄ左右用自来水冲洗４８ｈ，在室温下连续降解３７６ｄ并停止曝气１２２ｄ，然后再继续试验，所得ＣＯＤｃｒ去除率均在６０％左右。方差分析Ｐ＞０．０５，说明在整个试验期间，固定化微生物小球的活性无显著性差异。
Immobilized microorganism spherules have fairly good tolerance for aerobic degradation of high concentration Isocarbophos.When the initial chemical oxygen demand(CODcr)of water sample s 2145-I2500mg/L, spherules were washed in 48 h by tap waterat about 45 days intervals duringva 376 d period of continuous operation under room temperature and were deprived of aerating for 122 days, the removal rate of CODcr was all about 60%. The analysis of variance gave a probability of P>0.05.This indicates that the activity of immobilized microorganism spherules has no significant diversity during the whole period of experiment.
