Volume reduction method of water purification plant sludge

摘要

The present invention relates to a method that can be treated in large quantities by remarkably reducing the volume with only water purification plant sludge without adding any additives.;Recently, due to the increase in urban population, industrial water, and water pollution, the amount of sludge, which is an essential wastewater generated in water purification plants, is increasing rapidly. Therefore, waste landfills and dumping at sea are usually caused by serious problems such as lack of landfills, environmental pollution, increase in disposal costs, and limitation of disposal.;In order to realize this, the present invention focuses on the fact that when water sludge is thoroughly agitated, water and sludge are distributed evenly, so that cracks do not occur in the molding, so that the sludge can be recycled. As it is, pressurized and dewatered the sludge of the water purification plant, and it is molded into a pellet form while stirring and extruding and calcining without drying separately, thereby significantly reducing the volume of the water purification plant sludge at a relatively low cost through a relatively simple process. Soil soil, cultured soil, sawdust substitutes, flower bed micro fossils, zeolite substitutes, building materials, etc. can be used.
