Abstract：

As of 2021, the annual production of municipal solid waste in Chinese cities reached a staggering 150 million tons, with leachate from waste treatment accounting for approximately 25-30% of the waste volume. With the gradual increase in environmental protection requirements imposed by the government, there is an urgent need for advanced treatment of leachate. Nanofiltration membranes, characterized by unique pore sizes and charge effects, exhibit high separation precision for small organic molecules and divalent ions, making them promising for deep treatment of landfill leachate. However, membrane fouling has always been one of the inevitable key issues in the application of nanofiltration membranes. In this project, the anti-fouling nanofiltration membrane (AMNF-8040) produced by Nanjing Weihua Membrane Technology Co., Ltd. was employed to perform deep treatment on the leachate from a municipal landfill in Huainan, Anhui Province. The AMNF-8040 nanofiltration membrane achieved a CODCr retention rate of over 96.5% and an ammonia nitrogen retention rate of over 89.8% in the leachate. The treated water quality far exceeded national standards. Compared to a foreign brand of nanofiltration membrane used during the same period, the AMNF-8040 membrane demonstrated superior anti-fouling performance and exhibited good long-term stability. Therefore, the AMNF-8040 anti-fouling nanofiltration membrane shows broad prospects for application in the field of deep treatment of landfill leachate.
