Utilizing slime, sludge and urban building ceramic ash production method of desulfurization

Slime, municipal sludge and producing building ceramic ash desulfurization method of the present invention relates. With slime, sludge and urban desulfurization ash as the main raw material. Preferably, a the aforementioned main raw material ingredients, the chemical composition range: SiO2: Al2O3: (Fe2O3, K2O, Na2O, CaO, MgO, etc.) mass ratio of 53 to 79%: 10% to 25%: 13% to 26%. By granulation, drying, calcining, cooling is made ceramic. Water absorption of the finished ceramic ≤15%, a bulk density range ≤500kg / m3, compressive strength cylinder ≥0.3MPa. Standard Specifications to achieve "light aggregate and test method" GBTl7431.1-1998. Suitable for ceramic used in construction.
