摘要

As the lake water of Yuyuantan Park of Beijing has became micro-polluted water after the cycles of social landscape and the micro-polluted water run into the Kunyu River, the research adopts a method of manual simulation to treatment the micro-polluted water with a new-type of compound pattern we call landscape-designed ecological barrier which consists of ecological pond and constructed wetland . In order to weak the adverse effects of micro-polluted water on natural water, this new-type of compound pattern forms a landscape-designed ecological barrier. After 5 months experiment, results show that the landscape-designed ecological barrier has a better removal of pollutants. The removal rates of COD, TN and TP respectively reached 65.2% ~ 73.6%, 62.5% ~ 66.0% and 70.0% ~ 80.0%. And the effluent quality can reach III - IV water-quality of environmental quality standards for surface water(GB3838-2002). In Autumn, the concentration of CODCr, TN and TP in effluent sustain at IV water-quality of environmental quality standards for surface water(GB3838-2002), and at the same time create artificial landscape water with environmental aesthetic and ornamental value, bring the benefit of water resources as well as positive ecological environment effects into full play synthetically.
