Abstract: A set of practical technology for harmless disposal and resource utilization of river sediment was developed.The sludge with high water content was dehydrated and mixed with various auxiliary materials and compound bacteria in proportion for stacking fermentation.Finally，it was fully decomposed，which could effectively remove pathogenic microorganisms，Ascaris eggs and other harmful substances，and organic pollutants were fully degraded.Fermentation products and local livestock manure compost products after reasonable ratio and deep processing can be used in landscaping，flower planting，mine restoration and other fields to realize harmless disposal and resource utilization of sediment.
