Combined with the characteristics of high moisture, large volume, and low thermal value in the domestic sewage sludge, Huaxin Cement Kiln Cooperative Treatment Municipal Smoral Technology adopts deep dehydration and cement kiln remaining heat -drying. The mud is burned in the environment of negative pressure, high temperature, vortex, strong alkali, and restore in the cement kiln, which can achieve thorough treatment. In this process, there is no waste (odor), waste residue (low residue, fly ash) emissions at all, and truly realize the "reduction, harmlessness, and resourceization" of sewage sludge.
