This study investigates water quality variation of Shin-hai Contructed Wetland stageⅡ in Monsoon Season. The Shin-hai Contructed Wetland stageⅡ includes four major parts as: densed plant plot Ⅰ, open water, densed plant plot Ⅱ, and ecological pool. The densed plant plot has water volume of 4,080m³with aera of 10,200m² and average water depth of 0.4m, the hydraulic stayment aslong as 3.9 days. The open water, 7,488m³, 6,240, 1.2m, and 2.6 days, respectively; the densed plant area Ⅱ, 3,920m³, 9,800m², 0.4m, and 1.2 days; ecological pool, 3,000m³, 7,500m², 0.4m, and 1.1 days, respectively.
For the average value of water quality in dex in May, BOD5 decrease from the inflow of 38 mg/l to the outflow of 15 mg/l, with pollutant reduction of 99.2%; NH3-N, 19 mg/l, 12 mg/l, 36.8%; TP 2.2 mg/l , 0.58 mg/l, 73.6%. While in June, BOD, 39 mg/l, 28 mg/l, 35.9%; SS, 185 mg/l, 10 mg/l, 94.6%; NH3-N, 8.8 mg/l, 4.1 mg/l, 53.4%; TP, 1.0 mg/l, 0.68 mg/l, 32%. Except the only worser value of NH3-N in May, the efficiency of others is higher in June.
