<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[In this study， FeO was added to promote anaerobic digestion. The effects of FeO on the anaerobic digestion of high calcium papermaking wastewater was discussed by analyzing the changes of cumulative methane production， maximum methane production rate in the anaerobic reactor and the changes of extracellular polymer substance components （proteins， polysaccharides and humus） and microbial community in the anaerobic granular sludge. The results showed that the addition of FeO promoted the methanogenic activity. The cumulative methane productions of the simulated high calcium papermaking wastewater were increased by 59.4% and 82.3% in compare with those of the control when adding 1 and 15 g/L FeO， respectively. Adding FeO to the actual papermaking wastewater A and papermaking wastewater B could increase cumulative methane production by 52.0% and 85.4%， respectively. FeO could increase the content of extracellular polymer and promote the growth and metabolic activity of microorganisms. The addition of FeO changed the microbial community， and the diversity of microbial community was significantly improved， which enhanced the stability of anaerobic digestion reaction. Therefore， the addition of FeO was helpful to improve the methanogenesis capacity in anaerobic digestion process and could treat high-calcium papermaking wastewater more efficiently.]]></description>
