A METHOD FOR SOLIDIFICATION AND STABILIZATION FOR SEWAGE SLUDGE

摘要

PURPOSE: A method for solidifying and stabilizing sewage sludge is provided to suppress ammonia by minimizing the rise of pH when the sewage sludge and an additive are mixed. CONSTITUTION: A ladle slag of 10 to 20 % and a DAP of 10 to 20 % are mixed in sewage sludge of 100 %. The ladle slag of 10 to 20 % and hydroxyapatite of 10 to 20 % are mixed in the sewage sludge of 100%. The ladle slag of 10 to 20 % and the waste phosphogypsum of 10 to 20 % are mixed in the sewage sludge of 100%. The ladle slag of 10 to 20 % and FeSO4 7H2O of 10 to 20 % are mixed in the sewage sludge of 100 %.
