ACTIVATED SLUDGE WASTEWATER TREATMENT PLANT CONSTRUCTION MATERIALS AND MANUFACTURING METHOD

The present invention relates to a construction finishing material in which purification plant sludge and spent active carbon are mixed with each other and a method for manufacturing the same and, more particularly, to a construction finishing material using purification plant sludge and spent active carbon that uses purification plant sludge which has a dehumidification capability for indoor humidity control and active carbon blocking harmful substances of a volatile organic compound and formaldehyde and a method for manufacturing the same. In the construction material according to the present invention, the purification plant sludge is plasticized and then powdered so that dehumidification is performed and the harmful substances of the volatile organic compound and formaldehyde are blocked and the active carbon, which is a main component, is mixed with materials of red clay, a mixing agent, and a solidification agent. Also, the construction finishing material using the purification plant sludge is obtained through a first step in which 10 to 40 wt% of plasticized and powdered purification plant sludge, 10 to 20 wt% of active carbon, 40 to 60 wt% of red clay, and 5 to 10 wt% of mixing agent are mixed; a second step in which the mixture obtained in the first step is mixed with 5 to 10 wt% of solidification agent; and a third step in which the mixture obtained in the second step is molded and cured in a molding frame.
