摘    要:利用筛选得到的5株性能良好的异养硝化-好氧反硝化菌,采用两两组合方式,构建出了优于单一菌株脱氮活性的复合菌群F1.研究了该复合菌群的生长曲线,探讨了盐度对复合菌群F1的脱氮性能的影响.研究表明:复合菌群F1在盐度2.0%,3.5%的条件下均能生长.在盐度0,2.0%,3.5%的条件下,NH4+-N和TN去除率在48,84,96 h时均达到80%以上,值得一提的是,复合菌群F1在盐度2.0%时,NH4+-N和TN去除率仍很高,均在94%以上.复合菌群F1在处理实际味精废水方面具较高应用价值.

关 键 词:异养硝化  好氧反硝化  复合菌群  脱氮

Abstract:Multiple microorganisms F1 with higher efficiency were constructed with five strains which had good performance of heterotrophic nitrification-aerobic denitrification.The characteristics of multiple microorganisms F1 built by two-two combinations is better than a single strain.The effect of salinity on the removal rates of ammonia of multiple microorganisms F1 was studied.Multiple microorganisms F1 could grow at the salinity of 2% or 3.5%.The maximum removal rates of ammonia and TN were over 80% at 48,84,96 h with the salinity of 0%,2.0%,and 3.5%.It is worth mentioning that the maximum removal rates of ammonia and TN were over 94% at the salinity of 2%.The results indicated that multiple microorganisms F1 could deal with monosodium glutamate wastewater and had a great practical value.
Keywords:heterotrophic nitrification  aerobic denitrification  multiple microorganisms  nitrogen remove
