| 摘 要： | 水体的富营养化是水体中氮磷等营养物质的过量排放引起的.其中，磷是产生水体富营养化的主要元素，磷含量超过0.02 mg/L时就能产生富营养化现象.为解决水体富营养化的环境污染问题，对除磷工艺的研究具有重大意义.文中综述了利用微生物法、化学法和物理化学法对磷的去除工艺，并着重介绍了废水化学和物理化学除磷中化学混凝沉淀法、结晶法、吸附法的特点及应用现状.阐述了化学除磷的发展方向，进一步提出开发更经济环保的化学除磷技术.

| Abstract: | The eutrophication of water bodies is usually caused by excess emission of nutrients such as nitrogen and phosphorus in water bodies. Phosphorus is the main element limiting the eutrophication of water bodies. When the phosphorus content in the water column exceeds 0.02 mg/L, eutrophication can occur. It is of great significance to study the dephosphorization processes to solve the environmental pollution of eutrophication. In this paper, dephosphorization processes by microbial, chemical and physical-chemical methods were reviewed. The characteristics and application status of chemical coagulation precipitation, crystallization and adsorption methods in chemical and physical-chemical dephosphorization were emphatically introduced. This paper described the development direction of chemical phosphorus removal, and further proposed the development of more economical and environmentally friendly chemical dephosphorization technologies. |
