Implementation of the new discharge standard for landfill leachate makes most landfill leachate projects in China face technical upgrade. The status of leachate treatment technologies and the main problems were analyzed. The development directions of different technology links were discussed on the base of the main engineering technical route of ’pre-treatment +biological treatment + advanced treatment’. It was put forward that the upgrading of existing technologies, and development and industrial application of new technologies were key areas for landfill leachate treatment technologies development. In these areas, the development and application of advanced oxidation technologies based on hydroxyl radical was an important research direction. Also an efficient integration between advanced oxidation processes and biochemical processes was a significant direction of technology development. The research results provided references for landfill leachate renovations and new building landfill leachate projects to meet the new standards.
