【摘要】 <正>固定化微生物技术在污水处理应用中由于其微生物浓度高、能纯化并保持高效菌种、处理效率高、稳定性强及固液分离效果好等优点而越发受到重视。聚乙烯醇(PVA)是为数不多的已工业化生产的可从天然气制备的通用水性高分子材料,具有强度高、生物相容性优良、对微生物无毒及价格低廉等特点,是理想的固定化载体材料[1]。本文针对PVA固定化微生物水凝胶载体在实际污水处理中对其力学稳定性及传质性能的特殊要求,采用具有表刚内韧特更多还原

【Abstract】 Based on the requirement of mechanical stability and mass transfer performance for the PVA hydrogel immobilized with microorganism applied in the wastewater treatment,the rigid elastic polyacrylate nanoparticle(ACM)was used to be composited with PVA for the purpose of strengthening and toughening PVA hydrogel.The crosslinking kinetics of PVA composite system and the porous network structure of the hydrogel were studied to explore the toughening mechanism.The wastewater treatment property of the hydrogel was further investigated.更多还原
