Constructed wetlands, commonly known as ground filters, are well suited mostly for wastewater treatment in areas with no central sewage system. The basic difficulty with exploitation of constructed wetlands is connected with irregular hydraulic overload of its surface. However, irregular wastewater inflow can be reduced by cyclical irrigation which increases efficiency. The unquestionable advantage of the constructed wetlands is inexpensive construction and exploitation as well as low energy consumption. The constructed wetlands also fit very well in surrounding area. The investigation concerned the analysis of two constructed wetlands which are composed of mechanical separation (septic tank) and a filter bed with subsurface flow. The research has been undertaken in a period from July to December 2008, with regard to concentration distribution of nitrogen compounds in municipal sewage after constructed wetlands. The preliminary investigation on constructed wetland which has been exploited for 10 years showed variable removal efficiency of nitrogen compounds. The continuation of the research can indicate the efficiency of wastewater treatment in summer and winter season.
人工湿地，通常被称为地面过滤器，非常适合在没有中央污水系统的地区进行废水处理。人工湿地开发的基本难点与地表不规则水力过载有关。然而，通过周期性灌溉可以减少不规则的污水流入，从而提高效率。人工湿地的一个无可置疑的优势是建造和开发成本低廉，能耗低。人工湿地也非常适合周围环境。该研究分析了由机械分离（化粪池）和地下流过滤床组成的两个人工湿地。该研究于 2008 年 7 月至 12 月进行，涉及市政污水经过人工湿地后氮化合物的浓度分布。对已开发 10 年的人工湿地的初步调查显示，氮化合物的去除效率存在差异。继续研究可以表明夏季和冬季污水处理的效率。
