APPARATUS FOR SOLIDIFYING SEWAGE SLUDGE HAVING DEODORIZATION DEVICES CORRESPONDING TO CHARACTERISTICS OF SOLIDIFICATION STEPS

摘要

Disclosed is an apparatus for solidifying sewage sludge having deodorization devices corresponding to characteristics of solidification steps in order to sequentially remove odor in each step of sewage sludge solidification. The apparatus for solidifying sewage sludge comprises: an insertion unit (10) into which sewage sludge is inserted and which sprays a deodorant to sewage sludge so as to remove acidic odor through an air injection nozzle; a first conveyor (48) which transports the sewage sludge and sprays a deodorant to sewage sludge so as to remove basic odor through the injection nozzle; a mixing unit (30) for mixing the sewage sludge transported from the first conveyor (48), iron sulfate and a solidification agent; a second conveyor (78) which transports a sewage sludge mixture discharged from the mixing unit (30) and sprays a deodorant to the sewage sludge mixture so as to remove basic odor through the injection nozzle; a solidification unit (60) for solidifying sewage sludge by injecting the solidification agent into the sewage sludge mixture transported from the second conveyor (78); a third conveyor (98) which transports solidified sewage sludge materials discharged from the solidification unit (60) and sprays a deodorant to the solidified sewage sludge materials so as to remove basic odor through the injection nozzle; and a drying unit (80) which dries and cures solidified sewage sludge materials transported from the third conveyor (98) and sprays a deodorant to the solidified sewage sludge materials so as to remove basic odor through the air injection nozzle.;COPYRIGHT KIPO 2015
