Processing method for preparing bricks by utilizing urban domestic sludge

The invention discloses a processing method for preparing bricks by utilizing urban domestic sludge, which relates to the processing and the utilization of the urban domestic sludge. The processing method comprises the following steps: granulating and drying the sludge for aging; uniformly mixing aged granular materials with shale or clay or coal slag or building rubbish according to the proportion by weight; after the mixing, adding an amount of water for preparing brick blanks and continuing stirring and mixing; preparing the blanks; sintering the blanks; and preserving heat and cooling the blanks to obtain the bricks. The invention greatly saves resources and provides an active sludge processing and utilizing scheme. Some of the strength indexes of the prepared bricks even exceed those of the bricks prepared by ordinary processes. During roasting, for the condition that tail gas generated in the process of roasting the sludge bricks contain more sulfur and chlorine ingredients, a combined desulphurizing and deodorizing technology inside and outside a furnace is used, namely, the limestone is added in to a burning furnace, and water is sprayed to the tail gas under a sealing condition, thus a desulphurizing reactor does not need to be arranged on a tail part so as to ensure that smoke gas reaches an emission standard.
