- Abstract:
- Under the background of high discharge standards of surface quasi?Ⅳ and above, most wastewater treatment plants (WWTPs) still struggle to meet the standards after strengthening their secondary biochemical treatment capacity, and need to increase the advanced treatment process. In recent years, the upflow denitrification filter (UFDN) application as a highly efficient advanced treatment process has gradually increased. This paper summarizes the advantages, basic principles, design parameters, engineering applications, and research results achieved in the high discharge standards of the UFDN process. Combining with the industry development trend, the problems of the process were pointed out, and the direction of the future development of UFDN was prospected, so as to provide a reference for the relevant research and engineering applications.
