| 摘 要： | 采用上流式污泥床(UpflowSludgeBlanket简称为USB)反应器进行生物反硝化,在基质中添加较高浓度钙离子(300mgCa2+/L)条件下,系统中形成了大量颗粒污泥。本试验对USB反应器进行生物反硝化过程的颗粒污泥的形态、组成、结构进行了定性的研究,并对其不稳定性可能原因进行了分析。

| Abstract: | Granular sludge formed in a reactor of upflow sludge blanket (USB) has been studied for denitrification during treatment of the wastewater containing nitrite and nitrate. Calcium ions with high concentration were added in the influent to facilitate generation of big granules. The granules formed were investigated with regard to their morphology, ingredient and structure. Problem involved with instability of the granules was discussed. |
