Present Situation and Future Development Trend of Landfill Leachate Treatment Technology
The landfill leachate mainly comes from landfill and incinerator leachate,but with the development of garbage classification,the biogas liquid after anaerobic fermentation of wet garbage and the wastewater generated by garbage transfer stations have also become one of the main sources of garbage leachate.The leachate has high concentration of complex pollutants and great difficulty in treatment.With the continuous development of various technologies,the leachate treatment technology has formed a diversified situation.This paper introduces the water quality characteristics of four different sources of leachate and the current situation of existing treatment technology,gives the process flow of leachate treatment technology from different sources,and analyzes the characteristics and application scenarios of different process flows.At the same time,combined with the background of"carbon peak,carbon neutralization"and the development of garbage classification and the revision of leachate discharge standards in landfills,the current situation and future development trends of leachate treatment technology are analyzed.
