摘 要:碳源对生物反硝化的影响主要表现为:①对于高浓度含氨氮废水(一般都需要投加碱),碳源不足会使反硝化过程的产碱量降低,这将增大其硝化过程的外加碱量;并且由于反硝化进行不彻底,使出水中存在大量的NO2,出水COD增大;②碳源种类对反硝化效果有较大影响,单一基质和混合废水对反硝化反应的进程有不同的影响。The effects of carbon source on biological denitrification process are interpreted as 1) insufficient carbon causes decreasing of basic production in the denitrification process and increasing of the demand of basic dosage during treatment of wastewa-ter with high-ammonia nitrogen concentration. In this case also the COD level of the effluent will be higher because large quantity of NO2 caused by insufficient denitrification is existing. And 2) the effects on the denitrification will be different by various carbon sources, for example the effects on the progress of denitrification are different of mono-substrate and of mixed wastewater. The above mentioned problems have been discussed on the basis of operating practice of the denitrification station in Shanghai Coking Chemical Plant and the laboratory experiments.
