Abstract

The research group developed a pyrolysis-gasification-combustion pilot plant (PGCP) to treat rural solid waste (RSW). Based on the study of previous operating conditions, this study further explored the characteristics of potential secondary pollutants in the plant, such as slag, fly ash and flue gas. In the present study, X-ray fluorescence (XRF), X-ray diffraction (XRD) and scanning electron microscope (SEM) were used to analyze slag and fly ash. Besides, the leaching toxicity, content and morphology distribution of heavy metals (e.g., Cu, Pb, Cd, Zn and Cr) in the slag of PGCP were also studied as well as the emission characteristics of various pollutants in flue gas. Results show that slag mainly contains CaCO₃ and SiO₂, while CaCO₃ is mainly contained in fly ash. Moreover, the leaching toxicity of heavy metals in the slag did not exceed the limit value of the standard in China. The present study could provide technical support and data for optimizing the operation of plant-scale pyrolysis of RSW.

期刊介绍： Atmospheric Pollution Research (APR) is an international journal designed for the publication of articles on air pollution. Papers should present novel experimental results, theory and modeling of air pollution on local, regional, or global scales. Areas covered are research on inorganic, organic, and persistent organic air pollutants, air quality monitoring, air quality management, atmospheric dispersion and transport, air-surface (soil, water, and vegetation) exchange of pollutants, dry and wet deposition, indoor air quality, exposure assessment, health effects, satellite measurements, natural emissions, atmospheric chemistry, greenhouse gases, and effects on climate change.
