Sludge Treatment Tech for Ditches

    Ditch-cleaning sludge refers to the sediment found in municipal drainage pipeline systems, originating from particulate matter and impurities carried by the water in the drainage pipes, as well as solid substances that enter the drainage system via stormwater runoff, such as road dust, garbage, construction debris, and other miscellaneous materials. The treatment process for ditch-cleaning sludge involves washing and sorting the complex mixture of municipal ditch-cleaning sludge to separate it into four components: (1) coarse debris larger than 10mm; (2) coarse sand ranging from 0.2 to 10mm; (3) organic grating residues between 0.2 and 10mm; and (4) fine sand and powder smaller than 0.2mm. Among these, the coarse debris and organic grating residues are transported to landfills for disposal, while the coarse and fine sands can be recycled for use in low-grade building materials. This process not only addresses the pollution issues associated with ditch-cleaning sludge but also achieves waste utilization, energy conservation, emission reduction, and circular economy goals.
