【摘要】 咖啡渣资源化利用情况不理想，将其制备成低成本高附加值的生物炭，是近年来研究的热点课题。将咖啡渣生物炭进行酸碱改性，并协同过硫酸盐氧化，提高咖啡渣生物炭对水体腐殖酸（HA）去除率。对咖啡渣资源化、改性咖啡渣生物炭以及天然有机物去除的国内外研究现状进行阐述，以期为改性咖啡渣生物炭对水体中HA的去除研究提供参考依据。更多还原

【Abstract】 The utilization of coffee grounds is not ideal, and their transformation into low-cost, high-value-added biochar has become a research hotspot in recent years. By modifying the biochar with acid-base treatments and using persulfate oxidation, it is hoped to enhance the removal rate of humic acid(HA) from water bodies. This paper reviews the current research status of coffee residue resource utilization, modified biochar, and the removal of natural organic matter both domestically and internationally, providing a reference for the study of the removal of HA from water bodies using modified biochar.更多还原
