Abstract: In this paper，aquaculture wastewater was treated with combinational constructed wetlands system. The treated effects of TP，TN，NH4+-N and NO2--N were explored. The experimental results indicated that removal efficiencies of TP，TN，NH4+-N and NO2--N were 82. 45%-99. 79%（mean value 92. 75%），74. 09%-84. 63%（mean value 79. 33%），35. 27%-99. 13%（mean value 67. 84%）and 53. 62%-75. 98%（mean value 63. 38%），respectively under the experimental conditions. It can be found that removal efficiency of TP was better than that of TN and the purification effect of severe eutrophic water was better than that of special eutrophic water.

Key words: combinational constructed wetlands system, aquaculture wastewater, eutrophication, nitrogen removal, phosphorus removal
