【摘要】 人工湿地作为一种经济节能的污水处理方法,特别适合于城镇及小区的污水处理.对人工湿地在去除有机物和营养物质方面进行了初步研究.在平均水力负荷4 8cm/d时,间歇流和连续流人工湿地有机物平均去除率分别为78%和64%;氨氮平均去除率分别为60%和44%;总磷平均去除率为53%.结果表明,人工湿地内的氧含量对湿地去除效率有较大影响.更多还原

【Abstract】 The constructed wetland as a kind of sewage disposal method with energy-saving and economical is especially suitable for the sewage disposal of the town and uptown.This paper has carried on preliminary research to the constructed wetland in getting rid of the organic matter and nutriment.When hydraulic loading was 4.8cm/d,the average removal rates of chemical oxygen demand（COD） by batch-flow and continuous-flow constructed wetland was 78% and 64% respectively.The average removal rates of Ammonia-nitrogen（NH₄-N） was 60% and 44% respectively.Both of the average removal rates of total-phosphorus（TP） were 53%.The results indicated that the content of oxygen in the constructed wetland has greater influence to get rid of efficiency on the wetland.更多还原
