HYBRID ARTIFICIAL WETLAND WATER PURIFICATION SYSTEM, SEWAGE TREATMENT DEVICE USING SAME, AND NATURAL NONPOINT PURIFICATION DEVICE CAPABLE OF SIMULTANEOUSLY PURIFYING RIVER AND LAKE WATER

摘要

The present invention relates to a hybrid artificial wetland water purification system, a sewage treatment device using the same, and a natural nonpoint purification device capable of simultaneously purifying river and lake water, and more particularly, to a low energy, consumption-type multifunctional water quality purification system for a hybrid artificial wetland, a sewage treatment device using the same, and a natural nonpoint purification device capable of simultaneously purifying river and lake water, wherein the invention can selectively or simultaneously treat nonpoint pollution sources, which leak out during rain, in an advanced manner when being applied to treat point pollution sources such as sewage or waste water, or treating various pollutants that are contained in stream water or lake water. According to one embodiment of the present invention, 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.
