摘　　要：利用稳定运行的硫磺/白云石和黄铁矿/白云石自养反硝化工艺,分别在进水中添加不同浓度的邻苯二甲酸氢钾,考察反应体系的去除效果及自养和异养反硝化的相对关系。在进水COD浓度从0 mg/L增加到250 mg/L时,硫磺/白云石反应器仍保持较高的脱氮效果,黄铁矿/白云石反应器出水NO-3-N浓度从10.31 mg/L降至2.09 mg/L;SO2-4的生成量随有机物添加量的增加逐渐减少,两个反应体系均同时进行自养和异养反硝化。硫磺/白云石反应器仍以自养反硝化为主。Using the stable operation of sulfur/dolomite and pyrite/dolomite autotrophic denitrification reactors,different concentrations of potassium hydrogen phthalate were added to the influent to investigate the removal effect of the reaction system and the relative relationship between autotrophic and heterotrophic denitrification.When the influent COD concentration increased from 0 mg/L to 250 mg/L,the sulfur/dolomite reactor still maintained a high denitrification effect.The NO-3-N effluent concentration in the pyrite/dolomite reactor decreased from 10.31 mg/L to 2.09 mg/L.The production of SO2-4 decreased gradually with the increase of organic compound addition.Autotrophic denitrification and heterotrophic denitrification were carried out simultaneously in sulfur/dolomite and pyrite/dolomite reactors.The sulphur/dolomite reactor is still dominated by autotrophic denitrification.
