The main sources of landfill leachate are：
1. Precipitation infiltration: precipitation, including rainfall and snowfall, is the main source of percolation
2. External surface water inflow: this includes the surface runoff and surface irrigation
3. Groundwater infiltration: groundwater is possible when the level of infiltration water in the landfill is lower than the groundwater level outside the site and there is no anti-seepage system installed
4. Garbage itself contains moisture: this includes the amount of moisture that the waste carries and the amount of adsorption from the atmosphere and rain
5. Water produced by the waste during degradation: the organic components in the waste produce moisture when decomposed within the landfill
Landfill leachate quality has the following characteristics：
1.High organic concentration, i.e. high COD, BOD concentration
2. Complex pollutants and large fluctuations in water quality
3. High ammonia nitrogen concentration
4. Heavy metal ion concentration and high salt content
Landfill leachate treatment process：
Landfill leachate is a liquid that is generated from landfills or incineration power plants and is a complex type of wastewater. Its water quality and quantity will change with the age and season of the landfill or plant. It contains high COD and ammonia nitrogen contents, and heavy metals.
