摘要:本研究针对化学机械制浆预浸渍段废液管道中出现的绿色泥状沉积物（绿泥）问题，以广西某企业生产线为研究对象，通过多种表征分析手段，系统探讨了绿泥的化学组分、微观结构及形成机理。结果表明，绿泥主要由木质素碱性降解产物、无机盐晶体及过渡金属-有机络合物构成，其绿色特征主要来源于铁离子与木质素降解产物中多元酚类配体形成的金属-有机络合物。回用碱液中富集的钙、镁、铁等金属离子是绿泥形成的重要物质来源。基于上述机理，提出了包括源头离子控制、过程螯合剂调控与定期系统清洗在内的多级防控策略，为化学机械浆生产系统中绿泥沉积的有效防治提供了理论依据与实践指导。
Abstract:Aiming at the problem of green mud-like sediments (green mud) occurring in the waste liquid pipes of the chemi-mechanical pulping (CMP) pre-impregnation stage, the production line of an enterprise in Guangxi was taken as the research object in this study. The chemical composition, microstructure and formation mechanism of green mud were systematically investigated by means of multiple analytical techniques. The results showed that the green mud was mainly composed of alkaline degradation products of lignin, inorganic salt crystals, and transition metal-organic complexes. The green mud characteristic was mainly derived from the metal-organic complexes formed by iron ions and polyhydric phenol ligands in lignin degradation products. The metal ions (such as calcium, magnesium, and iron) enriched in the recycled alkaline solution were identified as important material sources for the formation of green mud. Based on the above mechanism, a multi-level prevention and control strategy was proposed, which included source ion control, process chelating agent regulation and regular system cleaning. This study provided a theoretical basis and practical guidance for the effective prevention and control of green mud deposition in the CMP production system.
