摘要:: 磷去除是水污染控制的重要内容，同时全球面临着磷资源短缺的挑战。因此，开发废水同步除磷及磷回收技术迫在眉睫。基于此，采用具有分区结构的局域强化混凝（LEC）反应器，研究了其钙盐除磷及磷回收性能。结果表明，LEC反应器具有较高的除磷效率，去除率可达（99.44±0.59）%，残余磷浓度低至（0.35±0.37） mg/L，除磷成本为（1.05±0.02）元/kg。LEC反应器的沉淀物磷含量可达49.01%（以P₂O₅计），结晶度为84.64%，显示出较高的磷回收潜力。进一步以磷去除率、残余磷浓度、除磷成本、磷含量和结晶度等指标建立了针对除磷及磷回收的多维评估体系，结果显示LEC反应器在高效率除磷和高潜力磷回收等方面具有显著优势。

Abstract:: Phosphorus removal is a critical aspect of water pollution control, and the world is also facing the challenge of phosphorus resource depletion. Therefore, the development of technologies that simultaneously remove and recover phosphorus from wastewater is urgently needed. A locally enhanced coagulation (LEC) reactor with a partitioned structure was employed to investigate its performance in calcium salt-based phosphorus removal and recovery. The results showed that the LEC reactor achieved a high phosphorus removal efficiency, with a removal rate of up to （99.44±0.59）%, and residual phosphorus concentrations as low as （0.35±0.37） mg/L. The cost of phosphorus removal was as low as （1.05±0.02） yuan/kg. The phosphorus content in the precipitates reached 49.01% (as P₂O₅), with a crystallinity of 84.64%, indicating a high potential for phosphorus recovery. Further, a multidimensional evaluation system was established based on indicators such as phosphorus removal rate, residual concentration, removal cost, phosphorus content, and crystallinity. The results showed that the LEC reactor offered significant advantages in terms of efficient phosphorus removal and high phosphorus recovery potential.
