The Research Process of Chemistry Precipitation Method in Phosphorus Removal in Wastewater

Nowadays, water body eutrophication is very seriously in china and the world. More and more attention has been paid to water body eutrophication and the treatment on water body eutrophication is strengthened gradually simultaneously. Therefore, the requirement on the restriction of the phosphorus concentration in waste effluent will be more and more strict. Chemistry precipitation method has lots of advantages in phosphorus removal effect and fund input. So the application perspective of chemistry precipitation method in phosphorus removal is very great. In order to promote the development of the research on the chemistry precipitation method of phosphorus removal, the principle of chemistry precipitation method in phosphorus removal, the species of chemical precipitation agent and its research process, the influence factors of chemistry precipitation method and the research process of the combined method of chemistry and biology in phosphorus removal were reviewed, and the application perspective of chemistry precipitation method in phosphorus removal was looked into, the shortcomings and development trends of chemistry precipitation method were pointed out simultaneously.
