Design method and purification efficiency of integrated vertical flow constructed wetland |
| |
| Abstract: | The theory and design method of integrated vertical flow constructed wetland (IVCW) are explained; the investment and operation cost are analyzed and the purification efficiency of the system treating contaminated surface water is also demonstrated. The results of the pilot system show that the remove rates of chemical oxygen demand (COD\-\{Cr\}), five day's biochemical oxygen demand (BOD\-5) and total suspended solids (TSS) are 66.1%, 76.7% and 72.4% respectively. A full_scale system treating polluted surface water is introduced, it shows that the system can remove 82.6% COD and 85.8% BOD\-5. IVCW is a practical and effective wastewater treatment system with low investment and operation cost, it is easy to operate and maintain with high quality effluent so that can make significant contribution to the water quality improvement and rehabilitation of aquatic ecosystems. |
