Research status of extreme phosphorus removal in urban sewage
According to the research status of extreme phosphorus removal in urban sewage based on Libich minimum quantity rule,the demand for extreme phosphorus removal technologies in some regions of China were summarized.Taking the effluent TP mass concentration lower than 0.05 mg/L as an indicator of extreme phospho-rus removal,the challenges of extreme phosphorus removal were analyzed systematically,besides,the current ap-plication of several extreme phosphorus removal technologies were introduced,the application situations of those technologies for extreme phosphorus removal in different environmental conditions were discussed,and the cur-rent technical barriers and the research prospects of the said technologies were summarized.In order to facilitate the improvement of urban sewage treatment capacity in areas with sensitive TP water quality in China,the re-search provides useful reference and inspiration for sewage treatment and water environmental protection.
