组合型生态浮床处理农家乐污水

为了研究由水生植物与人工填料构建的组合型生态浮床对某农家乐污水的净化效果,通过将美人蕉和球形塑料填料组合在一起构建成组合型生态浮床,研究了该组合型生态浮床对农家乐污水的净化效果。结果表明,该组合型生态浮床对化学需氧量(COD)、总氮(TN)、氨氮(NH4+-N)和总磷(TP)都有较好的去除效果,去除率分别达到79.71%、73.88%、88.67%和85.61%,均明显高于基质对照组和植物对照组。可见在组合型生态浮床中,由植物根系吸收、填料吸附及微生物的协同作用对污染物的去除效果要优于单一系统,合理的植物-微生物组合对提高处理该农家乐污水效果具有较好的促进作用。该研究结果为构建适宜当地农家乐废水处理的组合型生态浮床提供了重要的参考和借鉴。

Combined ecological floating bed for farmhouse wastewater treatment

In order to study the purifying effect of combined ecological floating bed constucted by aquatic plants and artificial packing on the farmhouse wastewater,a combined ecological floating bed in the farmhouse wastewater was established by combining with the canna and spherical plastic packing.Results showed that the combined ecological floating bed had a good removal efficiency of COD,TN,NH4+-N and TP.The removal rates of COD,TN,NH4+-N and TP were 79.71%,73.88%,88.67% and 85.61%,respectively,which were significantly higher than the removal rates by single matrix control and single plant control.The results also showed that visible the synergism of plant absorbing,matrix adsorption and mcroorgannism in combined ecological floating bed was better than a single system to eliminate the pollutants and reasonable plant-microbial combination played a positive role in promoting purification effect on the farmhouse wastewater.And this study provided important experiences and reference for building combined ecological floating bed proper for local farmhouse wastewater treatment.
