【摘要】 以ABR反应器处理不同浓度的葡萄糖和生活污水的合成废水为研究对象,考察了Ca2+、Mg2+,Fe2+等金属离子在不同的负荷下对ABR反应器中颗粒污泥性能及运行效果的影响。研究结果表明:容积负荷在3.1-32.3 kgCODcr／(m3·d),Ca2+、Mg2+,Fe2+投量分别为50-100、100-150、10-20mg／L时,ABR反应器中颗粒污泥活性得到明显改善,并能明显地提高反应器的处理效果。更多还原

【Abstract】 The research on the effects of three divalent metal ions(Ca2+,Mg2+and Fe2+) on the anaerobic granular sludge characteristics under different organic loading rates in Anaerobic Baffled Re-actor(ABR) treating artificial wastewater composed of glucose and domestic sewage was carried out. The results showed that the notable positive effects were obtained with the dosages of Ca2+ 50-100 mg/L, Mg2+100-150 mg/L and Fe2+ 10-20 mg/L respectively with both obvious increase of biological activity of granular sludge and improved treatment efficiency under organic loading rates ranged from 3.1 to 32.3 kgCODCr/(m3·d).更多还原
