Excessive use of detergents in wide industrial processes results in unwanted surfactant pollution. Among them, sodium dodecyl sulphate (SDS) has well-known history to be used in pharmaceutical and industrial applications. However, if discharged without treatment, it can cause toxic effects on living organisms especially to the aquatic life. Floating treatment wetlands (FTWs) could be a cost-effective and eco-friendly options for the treatment of wastewater containing SDS. In this study, FTWs mesocosms were established in the presence of hydrocarbons-degrading bacteria. Two plant species (Brachiaria mutica and Leptochloa fusca) were vegetated and a consortium of bacteria (Acinetobacter sp. strain BRSI56, Acinetobacter junii strain TYRH47, and Acinetobacter sp. strain CYRH21) was applied to enhance degradation in a short-time. Results illustrated that FTWs vegetated with both plants successfully removed SDS from water, however, bacterial augmentation further enhanced the removal efficiency. Maximum reduction in SDS concentration (97.5%), chemical oxygen demand (92.0%), biological oxygen demand (94.2%), and turbidity (99.4%) was observed in the water having FTWs vegetated with B. mutica and inoculated with the bacteria. The inoculated bacteria showed more survival in the roots and shoots of B. mutica as compared to L. fusca. This study concludes that FTWs have the potential for the removal of SDS from contaminated water and their remediation efficiency can be enhanced by bacterial augmentation.

漂浮处理湿地中的植物-微生物协同作用，用于增强去除水中十二烷基硫酸钠

在广泛的工业过程中过度使用洗涤剂会导致有害的表面活性剂污染。其中，十二烷基硫酸钠（SDS）具有用于制药和工业应用的众所周知的历史。但是，如果不经处理就将其排放出去，会对生物尤其是水生生物造成毒性影响。浮动处理湿地（FTW）对于处理含SDS的废水可能是一种经济高效且环保的选择。在这项研究中，FTWs介观是在存在降解碳氢化合物的细菌的情况下建立的。植被了两个植物物种（Brachiaria mutica和Leptochloa fusca），以及一个细菌群落（不动杆菌属BRSI56菌株，不动不动杆菌）菌株TYRH47和不动杆菌属。应用菌株CYRH21）在短时间内增强降解。结果表明，两种植物都生长的FTW成功地从水中去除了SDS，但是，细菌增强进一步提高了去除效率。在FTTs中生长了B. mutica并接种了细菌的FTWs水中，SDS浓度（97.5％），化学需氧量（92.0％），生物需氧量（94.2％）和浊度（99.4％）的降低最大。与福斯卡菌相比，接种的细菌在B. mutica的根和芽中显示出更多的存活率。。这项研究得出的结论是，FTW具有从受污染的水中去除SDS的潜力，并且可以通过细菌增强来提高其修复效率。
