인공습지 내 거리에 따른 ORP, pH, DO 변화와 수질 관계 분석

Oxidation-Reduction potential, Dissolved Oxygen and pH have an effect on life and activity of microorganism. So, those have relationship with nitrification and denitrification. This study analyze variation of ORP, pH and DO concentration with distance from inflow in free water surface constructed wetland, and have an intent to make a investigation into self-purification of nutrient with that each parameters are related to ammonia, nitrite and nitrate.
