【摘要】 介绍了一种低技术系统——人工湿地应用于中国上海崇明岛处理农村高浊度富营养化水体。该系统由氧化塘和人工湿地复合而成。氧化塘内利用生态纤维填料强化微生物的种类和浓度,形成了藻菌共生体系;人工湿地底部基质采用比表面积大的陶粒,易于微生物挂膜和吸附悬浮颗粒物。结果表明:COD,TN,TP和浊度的去除率较高,平均去除率分别为43.60%,38.30%,65.38%和95.48%;处理效果呈现季节性变化,夏季净化效果最好。更多还原

【Abstract】 This paper introduces a low technology system—constructed wetlands to treat the rural high turbid and eutrophic water in Chongming Island of Shanghai,China. This system was integrated by combined with oxidation pond and constructed wetland. Ecological fibre packing reinforced the functions of microorganism to form the symbiotic system of algae and bacteria in the pond. Ceramic padding particles with large surface area in constructed wetlands were liable to form microbial biofilm and absorb suspended particles. As a result,the removal rates of COD,TN,TP,and turbidity were good,and the average removal rates were 43. 60% ,38. 30% ,65. 38% ,and 95. 48% ,respectively. The treatment efficiency changed with seasons,and the best season was summer.更多还原
