What are the Common Methods of Leachate Treatment?
Various methods are used to treat leachate, each with its strengths and limitations. Some common methods include:
Biological Treatment: Utilizes microorganisms to degrade organic pollutants in leachate. This process is effective for reducing BOD and ammonia nitrogen levels. Physical-Chemical Treatment: Involves processes like coagulation, flocculation, and adsorption to remove suspended solids and dissolved metals. Membrane Filtration: Employs technologies like reverse osmosis to separate contaminants from water, achieving high levels of purification. Advanced Oxidation Processes (AOPs): Use reactive species like hydroxyl radicals to break down complex organic pollutants into less harmful substances.
