| Abstract: | Zeolite is widely distributed in nature and has been widely applied in the field of water and wastewater treatment. Sev- eral modification methods of natural zeolite, including physical modification, acid modification, alkali modification, salt rare earth modification and organic cationic surfactant modification was introduced in this paper. The mechanism of modified zeolite for nitrogen and phosphorus removal in wastewater was discussed. Modified zeolite enhancing the nitrogen and phosphorus removal performance of wastewater treatment processes was reviewed. The research and application prospects of modified zeolite were put forward as well. |
