The main difficulties in the treatment of landfill leachate in China

Author: Hongjie Water

The main difficulties in the treatment of landfill leachate in China are as follows: 

The organic content of landfill leachate is high, and it contains a large amount of toxic and macromolecular organic matter. Using a single physicochemical or biochemical process cannot achieve standard discharge, and a combination of physicochemical and biochemical treatment processes must be used for treatment. How to choose a reasonable, economical, and effective combination process?

Garbage leachate generally has a high ammonia nitrogen content, making it difficult to achieve effective and complete denitrification. Due to the increase in the national emission standards for total nitrogen in leachate, higher requirements have been put forward for the treatment of leachate. Traditional treatment processes, especially the core biological treatment process, can generally effectively remove ammonia nitrogen from leachate, but the removal of total nitrogen is not ideal. How to improve the total nitrogen removal rate of biological treatment processes?

The significant changes in water quality and quantity have increased the difficulty of achieving stable discharge standards. The water quality and quantity of leachate vary greatly in different seasons and ages, which poses challenges to the selection and operation of treatment processes. How to fully utilize the maximum processing capacity of existing processes and ensure stable operation under established combination processes?

Due to the complexity of treatment processes and high treatment costs, current leachate treatment plants, in order to achieve standard discharge, in addition to using composite processes, often use membrane treatment processes mainly based on nanofiltration or reverse osmosis as the final deep treatment, resulting in long-term high treatment costs for leachate. How to reduce the treatment cost of leachate while ensuring the treatment effect?
