  • Hybrid artificial wetland water purification system, sewage treatment device using same, and natural nonpoint purification device capable of simultaneously purifying river and lake water
    Patent number: 9221698
    Abstract: A water quality purification system for a hybrid artificial wetland includes a first aerobic artificial wetland, an anaerobic artificial wetland, and a second aerobic artificial wetland. Here, the first aerobic artificial wetland induces a vertical flow of water, which is to be purified, and allows pollutants to be removed. The anaerobic artificial wetland induces a horizontal flow of treated water which is introduced from the first aerobic artificial wetland, and allows pollutants to be further removed. Additionally, the second aerobic artificial wetland induces a vertical flow of treated water which is introduced from the anaerobic artificial wetland, and allows air to be supplied inwardly such that the amount of dissolved oxygen of the introduced treated water increases.
