Abstract: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.
Keywords:rural domestic sewage; phosphorus; resource utilization; adsorption and crystallization; farming irrigation
