摘　　要：以上海焦化总厂焦化废水为原水，研究了悬浮污泥缺氧反应器和软性纤维填料床缺氧反应器对反硝化工艺的影响，并进行了两种反应器中污泥产率和氛平衡计算等。结果表明；软性纤维填料床反应器的反硝化速率和反硝化率高于悬浮污泥法反应器，ＣＯＤ去除率略高于悬浮污泥法，污泥产率略低于悬浮污泥法；反硝化过程的氮平衡结果表明ＮＯ－Ｔ－Ｎ主要是通过异化作用被还原为Ｎ２而去除的。oking wastewater of Shanghai Coke Plant was uSed as the raw sewage for investigating the denitrification effect rof attached-growth anoxic reactor and suspended-growth anoxic reactor,the former was packed with soft fibre medium.The sludge yield and the nitrogen balance in the two reactors were calculated.The experimentalresults indieatied that,the denitrification rate,the,denittification effieiency and the COD removal efficiency of the attached-growth anoxic reactor were superior to the suspended-growth anoxic reactor,the slude yield of the former was some what less than that of the later.In the denitrification process,the dominating part of NO-T-N wasconverted into introgen gas through dissimilatory process
