An innovative continuous flow process linking biological nutrients removal (BNR) with induced crystallization (IC) was used to remove nutrients and recover phosphorus (P) from synthetic and real domestic wastewater. The results showed that a good nutrients removal performance was found regardless of feeding solutions. P recovery efficiency from synthetic wastewater was 70.2% slightly less than that from real domestic sewage (74.2%). Importantly, P recovery can effectively enhance the subsequent biological P removal. Polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) analysis displayed an obvious shift in microbial community structure when switching feeding synthetic solution to real wastewater. A total of 13 bands were detected in sludge samples using synthetic and real domestic sewage, affiliated with 8 phyla or classes domain Bacteria (Alphaproteobacteria, Betaproteobacteria, Gammaproteobacteria, Flavobacteria, Actinobacteria, Sphingobacteria, Epsilonproteobacteria and Chlorobia). The results obtained here suggest that the continuous flow BNR-IC process is feasible for nutrients removal and P recovery from domestic sewage and is a promising technology for wastewater treatment combined with recycling of P elements.

一种创新的连续流程将生物营养物去除（BNR）与诱导结晶（IC）联系起来，用于去除营养物并从合成和实际生活污水中回收磷（P）。结果表明，不管进料溶液如何，都具有良好的营养去除性能。从合成废水中回收磷的效率为70.2％，略低于实际生活污水中的磷回收效率（74.2％）。重要的是，磷的回收可以有效地增强随后的生物除磷。聚合酶链反应-变性梯度凝胶电泳（PCR-DGGE）分析显示，当将合成溶液切换为实际废水时，微生物群落结构发生了明显变化。使用合成的和实际的生活污水在污泥样品中总共检测到13个谱带，Alphaproteobacteria，Betaproteobacteria，Gammaproteobacteria，Flavobacteria，放线菌，Sphingobacteria，Epsilonproteobacteria和Chlorobia。此处获得的结果表明，连续流BNR-IC工艺对于从生活污水中去除营养物和回收磷是可行的，并且是一种废水处理与P元素回收相结合的有前途的技术。
