Treatment of Leachate by Phytoremediation technique using Marigold and Colocasia Plants
Department of Civil Engineering, Dr. D. Y. Patil Institute of Technology Pimpri, Pune
Treatment of leachate is an important aspect in solid waste management and treatment system. A sustainable and economical method called phytoremediation makes use of plants to remove, degrade, or stabilize contaminants from polluted wastewater. In this work, the phytoextraction of zinc and copper from landfill leachate by Marigold and Colocasia plant is carried out. The efficiency of Marigold and Colocasia in the treatment of leachate is examined in this study. The findings demonstrated that plants greatly lowered the level of heavy metals in the landfill leachate. Marigold and Colocasia plants have a removal effectiveness of more than 95% for zinc in landfill leachate, with copper having the highest value at 44%. Both the chemical and biological oxygen demands (COD and BOD) are reduced by 87% and 67%, respectively. The average removal of pollutants is found to be 64%, 95% and 33% for total hardness, turbidity and pH for Marigold plant and 65%, 98% and 29% for total hardness, turbidity and pH for Colocasia plant.
