垃圾焚烧炉渣综合利用项目技术及管理现状分析

Analysis on Technology and Management Status of Comprehensive Utilization Projects of Bottom Ash from Municipal Waste Incineration Plant

炉渣规范化综合利用是建设现代化生活垃圾焚烧处理厂的必然要求。通过对炉渣综合利用项目的调研分析得出:在应用技术方面,湿法预处理-替代集料/制砖是当前我国炉渣综合利用主流技术路线,具体工艺流程取决于综合利用产品市场需求,并受产品质量要求、设备效率以及运行管理水平的影响;在管理方面,目前炉渣项目总体呈现建设水平不高、运行管理不规范等问题。建议通过制定炉渣综合利用技术规范,健全相关政府监管考核制度等措施,进一步提高我国焚烧炉渣综合利用项目运行管理水平。

Standardized and comprehensive utilization of bottom ash is an inevitable requirement for the construction of modern municipal solid waste incineration plant.Based on the investigation of bottom ash comprehensive utilization projects,it can be concluded that wet pretreatment instead of aggregate/brick making is the main technology route for comprehensive utilization of bottom ash in applied technology in China,while the specific process flow depends on the market demand of comprehensive utilization products,and is affected by product quality requirements,equipment efficiency and operation management level.In terms of management,the current bottom ash project generally has the issues such as low construction level,non-standard operation and management,etc.It is suggested to further standardize and improve the operation and management level of incineration bottom ash comprehensive utilization project in China by formulating technical specifications for bottom ash comprehensive utilization and perfecting relevant government supervision and assessment system.
