Abstract

Constructed wetland (CW), is considered one of the most promising future approaches for wastewater treatment from various sources at relatively low cost and with the minimized environmental impacts. In this study, an integrated system of constructed wetland cells with horizontal subsurface flow were designed, installed, and fed with fresh actual dairy industry effluent in continuous base. To investigate the simultaneous effect of arrangement and type of supporting media on the treatment efficiency, six identically designed CW system cells were installed using conventional naturally available cost-effective supporting media. The type and configuration of supporting materials were 100% gravel, 50% sand and 50% soil, 60% gravel and 40% sand, 100% sand, 50% sand and 50% soil, and 100 soil for CW1, CW2, CW3, CW4, CW5, and CW6, respectively. All CW cells were planted with Canna indica plant except CW5 was kept uncultivated as the control cell. The results revealed significant nutrients removal present with maximum removal efficiencies of 99% and 96% for phosphate and nitrates, respectively. The favorable results indicated the veracity of using constructed wetlands as an inexpensive sustainable technique for dairy effluent treatment.

通过人工湿地去除真实乳制品废水中的营养物质的绿色方法

人工湿地(CW)被认为是未来最有前途的处理各种来源废水的方法之一，成本相对较低，对环境的影响最小。在本研究中，设计、安装了一个水平潜流人工湿地池的集成系统，并在连续基地中使用新鲜的实际乳制品工业废水。为了研究支持介质的排列和类型对处理效率的同时影响，使用传统的自然可用的经济有效的支持介质安装了六个相同设计的连续水处理系统池。CW1、CW2、CW3、CW4、CW5、CW6的支护材料类型和配置分别为100%砂石、50%砂石+ 50%土、60%砂石+ 40%砂、100%砂石、50%砂石+ 50%土和100土。除CW5为对照细胞外，其余CW细胞均与美人蕉植株一起种植。结果表明，对磷酸盐和硝酸盐的最大去除率分别为99%和96%。这些良好的结果表明，人工湿地作为一种廉价、可持续的乳品废水处理技术是正确的。

期刊介绍： Waste and Resource Management publishes original research and practice papers on all civil engineering and construction related aspects of the resource management cycle, from the minimization of waste, through the re-use and recycling, to the management and disposal of residual wastes. Associated legislation, standards, socio-economic considerations and links with sustainable consumption and production are included. The range of subjects covered encompasses, but is not restricted to, strategies for reducing construction waste through better design, improved recovery and re-use, more efficient resource management, the performance of materials recovered from wastes, and, the procurement, planning, design, construction, operation and logistics of waste and resource management facilities.
