TREATMENT OF WASTE WATER USING CONSTRUCTED WETLANDS
Journal Title: PARIPEX-Indian Journal of Research - Year 2019, Vol 8, Issue 5
Abstract
Natural wetlands are being considered beneficial for food and habitat for wildlife, water quality improvement, flood protection and shoreline erosion control. There is increasing advocacy by environmental management scholars for the establishment of constructed wetlands in developing nations to combat this issue. A pilot scale model was designed and fabricated, in a plastic crate (600mmX 400mm x 450mm). In a total depth of 450 mm, the crate was filled with the subsequent layers (from the bottom): 300mm of Coarse Gravel (size: 40mm and 20mm), 150mm of River Sand and Typha Latifolia plants with their roots intact, where placed on the surface level. Suitable PVC piping was done for the inlet(influent), outlet(effluent) and for the distribution of the same. The influent chosen was the water from Dorai kere's lake. Initial testing for the various parameters like dissolved oxygen content, nitrate content, total solids, BOD, COD, pH value, etc. of the lake water was studied and recorded. The plants in the apparatus were watered daily by this influent. The retention time was one week, after the end of every week the effluent was tested and the results were obtained.
