[0002] With the enhancement of environmental awareness and the development of technology, the garbage treatment industry pays more and more attention to the effective treatment of landfill leachate. Landfill leachate is a kind of high-concentration wastewater produced in the process of garbage stacking and landfill due to rainwater leaching, surface water and groundwater soaking and fermentation decomposition. Its composition is complex, containing a large amount of organic matter, heavy metals and other harmful substances, which poses a serious threat to the environment. Therefore, efficient landfill leachate treatment technology has become one of the research hotspots in the field of environmental protection.

However, when using membrane separation technology to treat landfill leachate, the problem of membrane pollution often arises. Membrane pollution can lead to a decrease in membrane flux, increase operating costs, and frequent chemical cleaning or replacement of membrane components, which not only increases the complexity of operation, but also may cause secondary pollution.
