Abstract

In order to mitigate the risk posed by discharge of untreated wastewater and enhance the quality of wastewater prior to its release or reuse, it is important to adopt nature based treatment technologies. The current study was performed with objective to treat the primary treated sewage collected from a traditional Moving Bed Biofilm Reactor (MBBR) based Sewage treatment plant (STP) by using a two-stage French Type Vertical Flow Constructed Wetland (FVFCW). This pilot-scale study was undertaken in Banaras Hindu University Campus Varanasi, Uttar Pradesh. The wetland unit was a two-stage Vertical Flow Constructed Wetland system (VFCW) filled with two different filter media gravel & sand and planted with two different macrophytes Canna indica and Typha latifolia which was operated for Sustainable treatment of primary sewage. The VFCW was operated at three different Hydraulic loading rate (HLR) i.e. 1800, 2700, 3600 L/day for nine months. The VFCW performed for the treatment of different physicochemical parameters at given loading rates. The maximum removal efficiency of 72.37, 76.47, 100, 87.23, 41.41, 40.77 27.07% was recorded for COD, BOD, Turbidity, TSS, TDS, Phosphate and Ammonia respectively. Most of the Parameters showed maximum removal efficiency at HLR 2700 L/day. The study suggested that Experimental VFCW can be a sustainable solution for wastewater treatment in remote and rural areas of India as well small colonies due to its eco-friendly, cost-effective, low maintenance cost and lack of operational expertise.

法式垂直流人工湿地作为生活污水处理的可持续解决方案。

为了减轻排放未经处理的废水所带来的风险，并在排放或再利用之前提高废水的质量，采用基于自然的处理技术是很重要的。本研究的目的是利用两级法式垂直流人工湿地（FVFCW）处理传统移动床生物膜反应器（MBBR）污水处理厂（STP）收集的初级处理污水。这项试点规模的研究是在北方邦瓦拉纳西的巴纳拉斯印度大学校园进行的。湿地单元是一个两级垂直流人工湿地系统（VFCW），其中填充了两种不同的过滤介质砾石和沙子，并种植了两种不同的大型植物美美蕉和Typha latifolia，用于初级污水的可持续处理。VFCW以三种不同的水力加载速率（HLR）即1800、2700、3600升/天运行了9个月。在给定的加载速率下，VFCW对不同的物理化学参数进行了处理。COD、BOD、浊度、TSS、TDS、磷酸盐、氨的最大去除率分别为72.37%、76.47、100、87.23、41.41、40.77、27.07%。大部分参数的最大去除率为2700l /d。该研究表明，试验性VFCW可以成为印度偏远和农村地区以及小殖民地废水处理的可持续解决方案，因为它具有生态友好、成本效益高、维护成本低以及缺乏操作专业知识。

期刊介绍： Environmental Management offers research and opinions on use and conservation of natural resources, protection of habitats and control of hazards, spanning the field of environmental management without regard to traditional disciplinary boundaries. The journal aims to improve communication, making ideas and results from any field available to practitioners from other backgrounds. Contributions are drawn from biology, botany, chemistry, climatology, ecology, ecological economics, environmental engineering, fisheries, environmental law, forest sciences, geosciences, information science, public affairs, public health, toxicology, zoology and more. As the principal user of nature, humanity is responsible for ensuring that its environmental impacts are benign rather than catastrophic. Environmental Management presents the work of academic researchers and professionals outside universities, including those in business, government, research establishments, and public interest groups, presenting a wide spectrum of viewpoints and approaches.
