Leachate sewage treatment
Leachate refers to the polluted liquid that seeps out of solid waste, which contains many harmful substances and needs to be treated to prevent pollution to the environment. Methods for treating leachate usually include the following:
Compacting and controlling: During the landfill process, some leachate can be reduced by compacting and controlling the garbage pile.
Collecting and separating: The leachate is collected and physically or chemically separated to remove solid particles and other impurities.
Biological treatment: Using bioreactors, artificial wetlands and other methods, microorganisms are used to degrade organic matter and convert the organic matter in the leachate into relatively harmless substances.
Chemical treatment: Use chemical methods such as oxidation, precipitation, neutralization, etc. to remove pollutants in the leachate.
Evaporation and concentration: The leachate is evaporated and concentrated to reduce its volume, and some water and useful substances can be recovered at the same time.
When treating leachate, it is necessary to adopt appropriate treatment methods according to the specific situation and composition to ensure the treatment effect and environmental safety.
