Environmental Risk Analysis of Leachable Substances from Vitreous Residue of Solid Wastes Treated by High Temperature Melting

Abstract

High temperature melting is a harmless treatment technology for solid wastes, which is applicable to hazardous wastes containing heavy metals and other harmful substances, obtaining amorphous glassy substances. Vitreous residue usually has high stability and low leaching toxicity. This paper simulates the leaching test of vitreous residue under natural conditions in ordinary rain and acid rain, systematically detects the concentration of leachable substances of typical residue, and analyses its environmental risks according to groundwater quality standards, indicating that harmful substances such as heavy metals may bring potential environmental risks when the vitreous residue enters the environment.
