Abstract:

Landfill leachate with high toxicity and high pollution poses a serious threat to natural water sources,and its effective treatment technology is the top priority for solving environmental problems. Cultivating microalgae with landfill leachate can not only achieve the efficient removal of carbon,nitrogen and phosphorus in landfill leachate, but also improve the production of microalgae biomass and reduce CO2 emissions. However,pretreatment of landfill leachate before microalgae cultivation was indispensable due to the high pollutant content and high turbidity in the landfill leachate. In this paper,the characteristics of landfill leachate were summarized,the methods of wastewater pretreatment before culturing microalgae and their existing bottlenecks were discussed,and the use of microalgae biomass cultivated in landfill leachate was analyzed. At last,the role of using microalgae to treat landfill leachate in promoting the conversion of new and old kinetic energy and the construction of carbon neutrality in the country was prospected,and the direction of future scientific and technological research was pointed out. This paper could provide a reference for the treatment of landfill leachate and the effective integration of microalgae biomass.

Key words: landfill leachate, microalgae, wastewater pretreatment, biomass, carbon neutrality

摘要:

高毒、高污染的垃圾渗滤液对自然水源造成了严重威胁,利用技术手段对其进行有效处理是解决环境问题的重中之重。采用垃圾渗滤液进行微藻培养,可以在实现垃圾渗滤液中碳、氮、磷高效去除的同时,提高微藻生物质产量并减少CO2排放量。然而,垃圾渗滤液高污染物含量、高浊度的特点决定了其必须经过一定的预处理才能够用于微藻培养。总结了垃圾渗滤液的特点,探讨了用于微藻培养的渗滤液的预处理方式及其存在的瓶颈,解析了利用垃圾渗滤液培养微藻所获得的生物质的用途,展望了利用微藻处理垃圾渗滤液技术在推动国家新旧动能转换和碳中和建设中发挥的作用及其未来的科技攻关方向,为实现垃圾渗滤液处理与微藻生物质的有效集成提供参考。
