Abstract
The objective is to explore degradation and removal of nitrogen and phosphorus in each unit of pond when using an artificially enhanced ecological system treats petrochemical wastes. The system consists of anoxic pond, the aerobic pond and aquatic plants pond, aiming to achieve a coordinate treatment effect in the multi-habitat system. The system combines treatment effects including assimilation, decomposition, interception, absorption, adsorption and filtration of microorganisms, aquatic plants and soil in the anaerobic, anoxic and aerobic state. It shows that the system has a good removal effect on COD, NH3-N, TN, and TP, and the removal rate range for each is 26.7% ~ 48.6%, 55.4% ~ 91.3%, 20.4% ~ 43.6% and 25.7% ~ 46.4%, respectively. It is also found that the treatment effects change with seasons, which are the best in summer because of vigorous plant growth and strong microbial activity. In conclusion, the system has a higher efficiency to remove nitrogen and phosphorus than the traditional stabilization pond technology.
