With its enormous social and economical development, China is now experiencing a rapid increase in solid wastes generation and growing pressure for solid wastes management. Today solid wastes in China are mainly managed by a combination of landfill, incineration, and composting. Within different possible treatment routes, thermal plasma technology (TPT) offers the advantages of efficiently gasifying the organic contents of solid wastes into syngas that can be used for heat and power generation, and vitrifying the inorganics simultaneously into glassy slag with very low leachabilities. This process makes it feasible for near-zero emission into the environment while making use of all the useful components. Encouraged by the industrial operations of solid wastes treatment plants using TPT in some countries, several plasma demonstration projects have already been undertaken in China. This paper provides a preliminary overview of the current laboratory researches and industrial developments status of TPT for the treatment of solid wastes in China and analyzes the existing challenges. Furthermore, the future prospects for TPT in China are also discussed.
随着中国巨大的社会和经济发展，目前中国的固体废物产生量正在迅速增加，固体废物管理面临的压力也日益增大。如今，中国的固体废物主要通过填埋、焚烧和堆肥相结合的方式进行管理。在不同的可能处理路线中，热等离子体技术（TPT）具有诸多优势，它能有效地将固体废物中的有机成分气化为合成气，用于供热和发电，同时将无机物玻璃化为浸出率极低的玻璃状炉渣。这一过程使得在利用所有有用成分的同时，实现向环境的近零排放成为可能。在一些国家使用TPT的固体废物处理厂的工业运营的鼓舞下，中国已经开展了几个等离子体示范项目。本文初步概述了中国热等离子体技术处理固体废物的当前实验室研究和工业发展现状，并分析了现存的挑战。此外，还讨论了热等离子体技术在中国的未来前景。
