Selection of Plants for Constructed Wetlands Based on Climate and Area in the Interest of Processing Pollutant Parameters on Leachate: A Review

Abstract

Abstract The process of waste decomposition in landfills is a process that converts waste into organic fertilizer due to percolating rainwater from biochemical waste processes and wastewater content. range of pollutants may affect public health and the ecosystem around the landfill loca This process also dissolves heavy metals in the form of a leachate byproduct. The high tion. Therefore, it is crucial to treat leachate before discharge to water bodies. Landfill leachate processing can be carried out through 3 processes, consisted of physicochemical, biological, and the combination of physicochemical and biological. Currently, constructed wetlands as natural treatment are considered environmentally friendly to deal with water pollution. This writing aimed to determine the differences in the leachate landfill characteristics, drainage system, and plant species used in the constructed wetland. This writing is based on a literature review of experimental research on water treatment carried out with the same parameters as leachate and leachate treatment. The literature review results show that leachate landfill processing depends on leachate characteristics and is influenced by age, type of waste, region, and climate.
