Phytoremediation techniques of heavy metal in sewage sludge

Abstract

Abstract: Phytoremediation techniques are showing prospects for the environmental pollution. Phytostabilization and phytoextration of heavy metal in polluted soil by wetland plant were reviewed. Bio-accumulation, bio-transform and bioremediation of the heavy metal by microbe were analyzed. In this paper, the biological mechanism, research progress, the condition for improving accumulation efficiency, and the characteristics of phytoremediation on heavy metal in wetlands were doscussed.

Key words: Insect community, Diversity, Evenness, Dominance, Niche, Plum orchard
