Abstract

The micro-polluted river water was treated by using integrated horizontal-flow constructed wetland. The micro-polluted river water was mixed up by effluent from wastewater treatment plant in west of Changchun City and Leijia river water. The experimental results show that integrated horizontal-flow constructed wetland has better treatment effect on COD, TP, ammonia, nitrite and nitrate nitrogen. Meanwhile, the average removal rates can reach 54.7%, 87.6%, 75%, 80% and 30%. The main indicators of the effluent meet the state standards for surface water class V grade.
