摘要：NOVELTY - The method involves mixing a medium in a subsurface flow wetland to perform secondary-level water depth processing operation. Water is applied in the subsurface flow wetland. The medium is arranged in different areas that are contained with zeolite and steel slag materials. Ammonia nitrogen is added in the water. Concentration values of the ammonia nitrogen and nitrate nitrogen are calculated. Average phosphorus absorbing quantity of the steel slag is determined. Water level containing quantity of the ammonia nitrogen is calculated. USE - Secondary-level water nitrogen phosphorus removing amount sewage processing method. ADVANTAGE - The method enables improving phosphorus removal efficiency and optimizing phosphorus nitrogen in the wetland so as to promote nano water without toxic and green alga growing and restrain poisonous algae. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a subsurface flow wetland.
