摘　　要：废弃活性焦为活性焦脱硫脱硝后的筛下物,呈粉末状,难以回收利用,但其具有丰富的孔隙、较高的碳、氮含量,有潜力作为掺料应用于堆肥。将废弃活性焦与鸡粪混合进行堆肥,以秸秆、再生焦粉与新焦粉作为对比,跟踪堆肥过程中产品性质变化,比较最终堆肥产品性能及其对植物生长的影响从而探究废弃活性焦的添加对堆肥产品的影响以及废弃活性焦的最适配比。结果发现:添加废弃活性焦的堆肥产品腐熟后其含水率、pH、种子发芽指数(GI)、总养分及重金属含量均符合NY/T 525—2021有机肥料标准。废弃活性焦堆肥产品的pH、氮含量以及有机质含量均优于其他处理,狗牙根的株高和鲜重也优于对照。综合各项指标,废弃活性焦堆肥配比在40%时产品质量最佳。本研究表明利用废弃活性焦混配堆肥是可行的,相关结果可为废弃活性焦的资源化利用提供一定理论和技术支撑。Waste activated coke is a byproduct derived from the fragmental fraction of activated coke following desulfurization and denitrification.Though typically considered non-recyclable,this powdery substance seems to be a promising material for composting as an additive due to its porous structure and substantial carbon and nitrogen content.For this purpose,waste activated coke was mixed with chicken manure for composting.Straw,recycled coke powder,and fresh activated coke powder were also applied respectively for comparative analysis to investigate the effects of waste activated coke to compost and determine the optimal ratio of waste activated coke.The results showed that the water content,pH,seed germination index(GI),total nutrients and heavy metal content of the composted products with waste activated coke met the NY/T 525—2021 standards for organic fertilizer.The composting products with waste activated coke exhibited superior pH,nitrogen content and organic matter content;furthermore,incorporated with waste activated coke composted products were better,comparing to the other treatments.Finally,the results suggested that the optimal mixing ratio for waste activated coke compost was 40%.The results indicated that waste activated coke could be used as an additive for composting and the results provided both theoretical and technical insights into the resourceful utilization of waste activated coke.
