| Abstract: | Objective]To study the effects of 3 wetland plants on nitrogen and phosphorus removal in pig wastewater.Method]Using artificial wetland treatment technology,removal efficiency of Eichhornia crassipes,Phragmites australias and Alternanthera philoxeroides on NH+4-N,TP,CODCr were studied.Result]When the hydraulic retention time (HRT) was 20 d,the removal rate of CODCr,NH+4-N and TP was better by constructed wetland,the average removal rate reached 85.5%,90.6% and 82.2%,respectively,and achieved the desired goal.Conclusion]This process can meet the national standards for engineering treatment of pig wastewater. |
