Abstract
The invention discloses a wavy subsurface-flow constructed wetland landscape water body treatment system and method. The system combines a horizontal subsurface-flow constructed wetland with a vertical subsurface-flow constructed wetland to form a wavy subsurface-flow constructed wetland. By means of regularly arranging upper clapboards and lower clapboards inside the wetland and replacing a horizontal flow state with a wavy flow state, sludge flows in a plurality of modes which are connected in series and alternate in upstream and downstream flows, so that organic nutrient substances are sufficiently degraded to remarkably promote deposition of phosphorus; the sludge is repeatedly subjected to anaerobic and aerobic treatment, so that removing of nitrogen can be facilitated; appropriate limestone is added into the filler of the wetland to release Ca<2+>, so that phosphorus in the sludge generates insoluble deposition of calcium phosphate, and thus the removal rate of phosphorus is increased. Due to the adoption of modes, such as intermittent water distribution, water inflow to a water distribution pipe by forming openings in the bottom as well as serial or parallel operation of a plurality of wavy subsurface-flow constructed wetlands, the bed body of the constructed wetland plays a relatively large efficiency, the removal rate of nitrogen phosphorus and organic matters is increased and the sludge treatment capability is enhanced.
