| Abstract: | Introducing several main dephosphorization methods of wastewater,the paper discussed chemical deposition dephosphorization method,biological dephosphorization method and constructed wetland dephosphorization method in detail and analyzed their advantages and disadvantages: chemical deposition dephosphorization has higher phosphorus removal rate,but it will bring a large mount of sludge;biological dephosphorization is more convenient for operation,but phosphorus removal rate is lower;constructed wetland is a low-cost technique to remove phosphorus,but it should be developed. |

| Keywords: | chemical deposition method biological dephosphorization constructed wetland |
