A system and method for reducing pollutants in garbage leachate is disclosed. The system comprises multiple modules such as a screening module, a pH adjustment and mixing module, a separator module and a disinfection module operationally connected to each other. The screening module is configured to filter the leachate and the pH adjustment and mixing module is configured to adjust the pH of the filtered leachate to a predefined value. The leachate is mixed with a chemical or metal oxide composition, and the pollutants in the leachate are adsorbed by the chemical composition to provide a purified leachate. The separator module is configured to separate the adsorbed pollutant from the purified leachate. The disinfection module is configured to filter and disinfect the purified leachate to produce purified water. The method implemented using this system for reducing pollutants in a leachate is efficient and economical.
