Advances in the treatment of phosphorus-containing wastewater

Abstract In recent years, many rivers, lakes and oceans around the world have exposed to diverse contaminants or red tides due to excessive discharge of nutrients such as nitrogen and phosphorus. The high content of phosphorus often leads to the nutrition of water body. Water resources have been seriously threatened, which has brought great impact on environment and public health. Therefore, the removal of phosphorus from wastewater attracts more and more attention. This work reviewed the forms, hazards and treatment of phosphorus in wastewater, and focuses on the methods of phosphorus-containing wastewater such as chemical precipitation, adsorption, ion exchange, membrane separation and biological methods. With the current economic and development of world, the bio-treatment of phosphorus-containing wastewater will become a research trend in the future, and the research and development of new technologies for phosphorus-containing wastewater will be an important topic for the treatment of phosphorus-containing wastewater in the future.
