100 t/d餐厨垃圾预处理工艺优化与运行分析
Optimization and operation analysis on 100 t/d kitchen waste pretreatment process
以延吉市某餐厨废弃物资源化利用和无害化处理厂为研究对象,介绍了工艺优化后的各工艺单元,并分析运行现状及存在的问题。延吉市餐厨垃圾项目设计处理规模为100 t/d,经过预处理工艺优化后,采用“破碎+分选制浆+高温湿解”作为预处理主要工艺路线。优化后的工艺在运行稳定性和经济效益方面均有显著提升,餐厨垃圾的产油率从2.8%提高到4.8%,而产渣率从35%降低到10.2%,厌氧消化系统产生的沼气产量能够满足项目生产日常需求。
Taking a kitchen waste re-utilization and harmless treatment plant in Yanji city,China as the research object,each process unit after process optimization is introduced,and the operation status and problems are analyzed.This plant has e design scale of 100 t/d.After optimizing the pretreatment process,the plant adopts “crushing+sorting pulp+high-temperature wet decomposition” as the main pretreatment process route.The optimized process has a significant improvement in both the operational stability and economic efficiency,the oil production rate of kitchen waste increases from 2.8% to 4.8%,while the residue production rate reduces from 35% to 10.2%,and the biogas produced by the anaerobic digestion system in this plant is able to meet the daily demand from the production of the plant.
