Wet viscous sludge pretreatment method suitable for heat treatment technology

The invention relates to a wet viscous sludge pretreatment method suitable for a heat treatment technology, and aims to solve the problems of adhesion, wall hanging, poor air permeability, low reactivity and aggravated particulate matter emission in the heat treatment process of wet viscous sludge. The method is characterized by comprising the following five steps: analyzing and testing original sludge, screening out impurities in the original sludge, conditioning the sludge, extruding and granulating, and airing the granulated sludge. According to the invention, the plasticity, the overall binding force, the compressive strength, the air permeability and the reactivity of the sludge are remarkably enhanced by utilizing the characteristics of the added conditioner and the granulation and pressure application process, so that the heat treatment efficiency and effect of the wet viscous sludge are improved, the equipment operation cost is reduced, the particulate matter emission condition is improved, the enviro
