摘要
介绍了间歇式活性污泥法硝化、反硝化及连续硝化、反硝化的反应规律。试验结果表明，脱氮进行的顺利与否，主要决定于硝化反应完成的程度。但在反硝化过程，不投加有机碳源的反硝化速率远远低于投加有机碳源的速率。因此，在反硝化时，投加一定的碳源是必要的，它可以加快反硝化速率，缩短反应时间并减小反应器容积。
The reaction laws of nitrification\|denitrification and continuous
nitrification\|denitrification by the SBR method are described.It has been shown by the test
results that the denitration is mainly determined by the extent of the finished nitrification
reaction.However during the process of denitrification,the denitrification rate without a certain
amount of organic carbon source is much lower than that of the one with the organic carbon
source.Therefore,it is necessary to use a certain amount of carbon source during the
denitrification,which can speed up the denitrification rate,shorten the reaction time and reduce
the volume of a reactor.
