Preparation and method for drying sludge through deep dehydrating

The invention relates to a preparation and a treatment method, and especially relates to a preparation and a method for drying sludge through deep dehydrating. The preparation comprises: 0.000002 to 0.00001 parts of an organic polymeric flocculants, 0.00025 to 0.0025 parts of a coagulating modifier, 0.0005 to 0.00375 parts of a sterilizing deodorant, and 0.00025 to 0.0025 parts of a nucleating converting agent. The method comprises the following steps: a sludge gravity thickening initial dehydrating step, a sludge regulating step, a mechanical press-filtrating step, and a filtrate refluxing step. With the preparation and the method provided by the present invention, sludge deep dehydrating processes can be carried out in series, processing efficiency can be improved, and energy consumption can be reduced. The controllability of the method is high. With the method, recycling is realized.
