| 中文摘要: |
| 农村生活污水磷资源化利用是实现污水可持续治理及污染物减排的有效措施。农村生活污水中磷主要存在形式为溶解性磷酸盐，在黑水中磷含量约占80%。受自然条件、排水体制及生活方式等因素影响，不同地区磷浓度水平存在一定差异。本研究采用文献计量学方法分析现有污水磷回收技术原理及研究进展，基于农村住所与农田交融度高的自然条件，以农村污水减量化、资源化和生态化为导向，提出农村生活污水磷回收及资源化利用方式，即生物炭吸附、鸟粪石结晶、微藻培养以及农田灌溉。综合考虑技术经济性、有效性和可行性，探讨不同回收方法的适用条件，构建磷回收及资源化利用路径，为农村生活污水资源化利用提供新思路和新模式。 |

| Phosphorus resource utilization of rural domestic sewage is an effective measure to achieve sustainable management for sewage and the reduction of pollutant. Phosphorus in rural domestic sewage mainly exists in the form of soluble reactive phosphate, and the content of phosphorus in black water accounts for about 80%. In fact, there are certain differences between different regions in the phosphorus concentration, which is influenced by associated factors：natural conditions, drainage systems and lifestyles, etc. This paper used bibliometrics to analyze the principles of existing technologies and the current status of researches about sewage phosphorus recovery and proposed the ways to recycle and utilize phosphorus resources from rural domestic sewage, which was based on the natural conditions of high degree of intermingling between rural dwellings and farmland and oriented to rural sewage minimization, recycling and ecologicalization. These paths of phosphorus recovery and resource utilization was used to explore application scenes, analyzed with the comprehensive consideration of economy, technical effectiveness and feasibility, which would provide the novel ideas and models for the recycle of rural domestic sewage. |
