【摘要】 污水处理过程中,异养反硝化需要一定浓度的有机物来提供电子,促进脱氮反应进行。因此实际应用中,为达到良好的脱氮效果,经常会外加有机物作为碳源。通过外加乙酸钠和甲醇两种碳源,测定了脱氮反应的动力学过程,根据米-门模型确定了动力学参数。通过比较两反应器的优势,为以后在实际应用中根据不同的目的,有选择的选取效率高且经济合理的有机物提供参考。更多还原

【Abstract】 In the process of wastewater treatment,heterotrophic denitrification requires a certain concentration of organic matter to provide electrons and promote denitrification.Therefore,in practical application,in order to achieve good denitrification effect,organic matter is often added as carbon source.The kinetics of denitrification reaction was determined by adding sodium acetate and methanol as carbon sources.The kinetic parameters were determined according to the Mi-Gate model.By comparing the advantages of the two reactors,it can provide a reference for the selection of efficient and economical organic substances according to different purposes in future practical applications.更多还原
