Embodiment
[0030] Embodiment: A method for treating landfill leachate, fermenting the landfill leachate in an environment with a pH value of 7.0-7.6 and a temperature of 20-40°C. Since landfill leachate is acidic, sodium carbonate can be used to adjust the pH value. Sodium carbonate is less corrosive to the human body, less risk during transportation and use, and the neutralization reaction will not produce precipitation, and the generated carbon dioxide gas helps to ensure the low oxygen of the environment and improve the fermentation effect. Considering that the incinerator 16 takes heat conveniently, a medium-temperature fermenting flora of 20-40° C. is adopted to adapt to the situation that the amount of leachate is large and the temperature is high in summer. The fermentation time depends on the amount of landfill leachate, and generally changes seasonally. In summer, there is a lot of rain, a large amount of leachate, high temperature, and short fermentation time. On the one hand,...
