Treatment Technology of Wastewater Using Constructed Wetland and Its Application in Dongping Lake

nstructed wetland is an integrated ecosystem that has particular mechanism and function in treatment of wastewater. It is paid more attentions in many countries. Based on the research of all over the world, the article analyzed the development trend and integrated advantages of treatment technology of wastewater using constructed wetland. The application field of constructed wetland is broad, and its theory and technology make progress increasingly. The advantages of constructed wetland include correspondingly low investment, multiformity and pertinence of treatment systems, efficient purification capability and especial environment function. Constructed wetland also has deficiencies, but it can be hurdled through right maintenance. The article pointed out the widely applied prospects of ccmstructed wetland in China, especially control water pollulion of lakes, rivers and importanl water transfer projects. Dongping Lake is an important hinge of the East Route of the South - to - North Water Transfer, so its water quality is very pivotal to the project. At present, it is polluled by pollulanls from industries and clonmistie wasle wader in of the Dawen River valley. The main pollutants are CODCr, BOD5, suspended substance and petroleum. To protect water quality of Dongping Lake effectively, the aulhor advised to ulilize constructed wetland as a useful supplement melhod. The advice includes that how to choose the site and the types of constructed wetland and the types of vegetation. At last,the article pointed out the potential problems in the process of application and how to resolve it.
