Form PubMed.parison of interannual removal variation of various constructed wetland types.Hijosa-Valsero M, Sidrach-Cardona R, Bécares E.AbstractSeven mesocosm-scale (1m(2)) constructed wetlands (CWs) of different configurations were operated outdoors for thirty-nine months under the same conditions to assess their ability to remove organic matter and nutrients from urban wastewaters. CWs differed in some design parameters, namely the presence of plants, the species chosen (i.e., Typha angustifolia or Phragmites australis), the flow configuration (i.e., surface flow or subsurface flow) and the presence/absence of a gravel bed. It was observed that, in general, removal efficiencies decreased with the aging of the system and that seasonality had a great influence on CWs. A comparison was made in order to figure out which kind of CW was more efficient for the removal of every pollutant in the long term. Planted systems were clearly better than unplanted systems even in winter. Efficiency differences among CWs were not extremely great, especially after a few years. However, some types of CWs were more adequate for the removal of certain pollutants. The effect of the aging on the main parameters involved in pollutant removal in CWs (temperature, pH, conductivity, dissolved oxygen concentration and redox potential) was assessed. The efficiency of CWs should not be evaluated based on short monitoring periods (1-2 years) after the start-up of the systems, but on longer periods.对于不同类型的人工湿地年际去除率变化的比较建立了七个不同规模的中性试验生态系人工湿地,在相同户外条件下运行39个月,评估它们去除城市污水中的有机物和营养物质的能力。
这些人工湿地在一些设计参数上是不同的,即存在的植物种类,物种的选择,水流的类型(例如表面流或潜流)以及沙砾床的存在与否等方面的不同。
可以观察到通常来说,人工湿地的去除效率随着系统年龄的上升而降低,且季节性变化对人工湿地有很大的影响。
我们做了一个比较来找出在长期运行上来看哪种人工湿地对去除各种污染物更有效。
种有植物的系统即使在冬天也比没有植物的系统要好。
这些人工湿地的效率差异是不显著的,尤其在运行多年以后。
但是,某些类型的人工湿地更适合去除特定类型的污染物。
我们对年龄变化对人工湿地污染物去除的影响的主要参数(温度,pH,导电性,溶解氧浓度和氧化还原电势)也进行了评估。
对人工湿地效率评价不能基于建成后短期(1-2年)运行的系统,而是要运行更长时间以后的检测参数才更为有效。
Seasonal performance of an outdoor constructed wetland for graywater treatment in a temperate climateJokerst A, Sharvelle SE, Hollowed ME, Roesner LA.AbstractThe seasonal treatment efficiency of a pilot-scale constructed wetland system located outdoors in a semi-arid, temperate climate was evaluated for graywater in a comprehensive, 1-year study. The system consisted of two wetland beds in series--a free water surface bed followed by a subsurface flow bed. Water quality monitoring evaluated organics, solids, nutrients, microbials, and surfactants. The results showed that the wetland substantially reduced graywater constituents during fall, spring, and summer, including biochemical oxygen demand (BOD) (92%), total nitrogen (85%), total phosphorus (78%), total suspended solids (TSS) (73%), linear alkylbenzene sulfonate (LAS) surfactants (94%), and E. coli (1.7 orders of magnitude). Except for TSS, lower removals of graywater constituents were noted in winter--BOD (78%), total nitrogen (64%), total phosphorus (65%), LAS (87%), and E. coli (1.0 order), indicating that, although wetland treatmentslowed during the winter, the system remained active, even when the average water temperature was 5.2 +/- 4.5 degrees C.温带气候用于处理灰水的露天人工湿地随季节变化的运行情况对处于半干旱温带地区的中试规模的露天人工湿地系统的季节性处理灰水效率进行了为期一年的综合性评价。
