危险废物刚性填埋场工艺设计要点探讨

随着危险废物填埋场污染新标准的实施，刚性填埋场的建设成为当前危险废物处理的热门，其作为我国当下工业废盐等危废的主要处理手段，不仅保留了废物今后资源回收和再生利用的可能性，也是有效降低土壤地下水污染风险的重要途径。以成都危险废物处置中心三期项目（10万m3刚性填埋场工程）为案例，针对刚性填埋场在工艺设计中的要点，包括填埋作业方式、雨棚形式、防渗系统设计、渗滤液导排系统设计等做了全面分析和阐述，为刚性填埋场的实际工程应用提供借鉴。

Discussion on Technological Design Essentials of Rigid Landfill for hazardous Waste

The construction of rigid landfills has become a hot topic for the hazardous waste treatment now along with the implementation of new standards for the pollution of hazardous waste landfills. As the main treatment method for the hazardous wastes such as the industrial waste salt in China, the rigid landfill not only preserves the possibility of waste resources recycling in the future, but also effectively reduces the risk of soil and groundwater pollution as the important way. Taking Chengdu Hazardous Waste Disposal Center Phase III Project (100 000 m2 rigid landfill project) as a case, aiming at the essentials of rigid landfill in the technological design, the landfill operation methods, canopy forms, anti-seepage system design, leachate drainage system design and the others are completely analyzed and expounded, which can be referred for the practical engineering application of rigid landfill.
