Abstract:
Taking Pontederia cordata and Canna generalis which grow in natural wetland as materials,the purify and biological effcet of two kinds of plants under high concerntration of livestock wastewater was studied in outdoor simulated conditions.The correlation between clean and biological effect was also studied.The results showed that two species had good purify treatment effect for livestock wastewater:COD,TP,NH3-N were decreased from 1 615-2 364 mg/L,33-71 mg/L,115-224 mg/L to 136-280 mg/L,17-76 mg/L,0.5-9.0 mg/L,which could reach the standard of discharge.The physiological indexes of plants was in normal range and the plants grew well.The combination wetland plants of Pontederia cordata and Canna generali in constructed wetland not only had good landscape effect,but also had high purify effect for livestock wastewater.
