Advances in Studies on Nitrogen and Phosphorus Removal by Microalgal-Bacterial Consortia

With the development of life and industry, nutrients in sewage increased gradually. The emerging symbiotic system algal bacteria has remarkable effect removing such as nitrogen phosphorus. In this paper, influence phosphorus on bacteria-algal consortia absorption mechanism by interaction were analyzed, a variety methods for studying summarized, mainly using isotope tracer technology to study research results algae absorbing water. This method is great significance analyzing treatment bacterial-algal symbiosis from microscopic point view.
