Abstract:

为了考察单级好氧工艺处理垃圾渗滤液的可行性和脱氮性能,采用脉冲进水式SBR工艺处理高氨氮实际垃圾渗滤液。脉冲SBR运行周期共分为4个缺氧段和3个好氧段,采用3次等量进水模式。缺氧4(An4)不投加外碳源,利用微生物内碳源将NO2--N还原为N2。结果表明,经过4个不同进水TN阶段(118d)的连续运行,获得了稳定和高效的脱氮性能。在进水COD为733~3971mg·L-1的条件下,出水COD稳定在298~888.15mg·L-1;在进水TN为299.78~1100.34mg·L-1的条件下,出水TN稳定在13.89~36.27mg·L-1。An4的平均理论内源反硝化速率(TDNRm)达到1.53mgN·h-1·(gMLVSS)-1。运行阶段的单个周期内,An4内源反硝化速率(DNR)分为快(DNR1)和慢(DNR2)两部分。其中阶段2(Ph2)中的一个周期内DNR1可达2.80mgN·h-1·(gMLVSS)-1。在没有物化预处理和不投加外加碳源的情况下,实现单级好氧系统对垃圾渗滤液的深度脱氮。
