Comparing with other methods, ecological beds have some typical features like low cost, low energy-consumption and highly efficient technology. The mechanism of ecological beds and the use of ecological beds in XiBaiPo power plant are reported in this paper. In the XiBaiPo power plant, the synergistic action between GaoYangMao and reed will reduce the adverse impact from climate and improve the ratio of contaminant degradation. The method is used to reduce sludge volume and using it as a soil fertilizer, soil amendment and landfill cover.
