EQUIPMENT SYSTEM FOR FORMING SUPERLIGHT-WEIGHT AGGREGATE FROM SEWAGE AND WASTEWATER SLUDGE

摘要

The present invention relates to a system for recycling, and wastewater sludge into lightweight aggregate with micropores, More specifically, in making these processes the sludge arising from wastewater treatment plant or wastewater treatment plants, the sludge mixed with clay and bottom ash has to be expandable with jeomgyeolseong dried to a moisture content of 25-40% sludge and mixing them and then homogeneously mixed in, compressing the mixed sludge to eliminate the pores of the pellets inside the sludge screen (pellet) in a spherical shape having a predetermined strength, which, by using a counter-current rotary firing furnace firing to 950~1300 , many is directed to a system for creating a lightweight aggregate with micropores. ; lightweight aggregate produced in this way is a low density, thermal insulation also excel as well as having a high hardness, it has a civil engineering and construction economics can be used widely as a raw material in the material. Therefore, to be able to handle the large amount of wastewater and sludge according to the system of the present invention as well, the effect of improving the environmental pollution problem is exhibited by allowing recycle and cause the pollution of wastewater sludge as a construction material.
