  • 摘要: 选择石砾、粗砂、细砂作为垂直流人工湿地的基质在实验室内研究不同粒径的基质在不同的水力负荷和对不同浓度污水对污染物的去除效果,根据实验结果选取基质应用于示范基地,利用人工湿地模型Subwet2.0对人工湿地示范基地进行模型模拟,为农村生活污水人工湿地系统的处理设计及模拟出水水质提供参考。研究结果表明:石砾、粗砂、细砂为基质对污染物去除率较好的水力负荷分别为小于0.9、0.6和0.3 m/d时;石砾基质对COD的最佳污染负荷为970 mg/L,粗砂、细砂基质为468~970 mg/L;粗砂和细砂基质对NH4+-N去除效果相似;在北方地区垂直流人工湿地主体基质建议使用粗砂或石砾以减少堵塞的风险;利用Subwet2.0模型模拟人工湿地示范基地的出水水质,根据当地条件在反应参数的取值范围内调整了相应的参数值,模拟的结果符合性很高。
    Abstract: Selecting gravel, medium grained and fine sand as substrate gradients, their nutrient removal effects in vertical constructed wetland were studied under different hydraulic loading and wastewater concentrations. The best substrate was chosen and applied in demonstration base wetland. The sewage effluent quality of the demonstration base wetland was simulated by model Subwet2.0 to provide a reference for the design of rural sewage treatment. Results showed that to maintain a good performance the hydraulic loading should be lower than 0.9, 0.6 and 0.3 m/d with gravel, and medium grained and fine sand as substrate, respectively. The optimum COD loading was 970 mg/L with gravel substrate, while 468 to 970 mg/L with medium grained sand and fine sand. Medium grained sand and fine sand have similar performance on NH4+-N removal. Medium grained sand or gravel was recommended for vertical constructed wetland to reduce the clogging risk in the north region. The simulation results of Subwet2.0 model matched well with real case with adjustment on the parameters according to local conditions.
