Technology Research for the Removal of Heavy Metals from Municipal Sludge

Article Preview

Abstract:

Heavy metal pollution is one of the main obstacles of municipal sewage treatment plant sludge for agricultural use. This paper gives an overview of four kinds of commonly used techniques for heavy metals removal in sewage sludge: chemical extraction, bioleaching, electrokinetic technology and solidification - stabilization, also analyzed the future direction of development.
