缺氧-好氧生物膜法脱氮系统中各类菌株分布的探讨

Study on Bacteria Species Distribution in a Denitrification System by Anoxic-aerobic Biofilm Process

在淹没式生物膜法缺氧（Ａ段）－好氧（Ｏ段）系统对煤气废水进行脱氮处理工艺中，氨化菌、反硝化菌和硝化菌在氮的转化过程中最为重要，只有这几类细菌发挥正常功能，才能达到脱氮目的。本文在试验中测定了这几类菌的数量，初步确定了它们在填料上和水中的分布情况，并同时测定了一些相应的水质指标，以利对比分析。

Ammonifier, denitrifier and nitrifier play important roles in denitrification treatment of gas wastewater by anoxic-aerobic System with the submerged biofilm. The System showed excellent nitrification performance only when these bacteria were functioning normally. The numbers of these bacteria were determined in the experiment, and their distribution was observed on carriers and in the water. The concerned parameters of water quality were measured for comparison.
