摘要
PURPOSE: A vegetation wetland system for urban non-point pollutant treatment is provided to effectively remove nitrogen and phosphorus by aerobically and anaerobically decomposing urban non-point pollutants. CONSTITUTION: A vegetation wetland system for urban non-point pollutant treatment includes a settling storage bath(101), a pumping-water spraying part(102), and a purifying bath(103). The settling storage bath settles and stores initial rainwater effluent or urban non-point polluted water. The pumping-water spraying part pumps the initial rainwater effluent or the urban non-point polluted water, and sprays the pumped water to a planting layer(104). The purifying bath is composed of an unsaturated part and a saturated part. The unsaturated part is composed of the planting layer, a cilium-phased filtering layer(105), and a soil-based filtering layer(106). The saturated part is composed of a coarse gravel layer(107).
