Many sludge curing technologies often have problems like long curing time, high cost, and low efficiency in the condition of low temperature. The compressive strength, moisture content and temperature are defined as the constraint conditions, and solidified cost, pH, COD, NH4 (+)-N concentration are defined as the objective functions. The response surface analysis is used to obtain a variety of response expressions of factors, and the multi-objective optimization model of fast-solidification sludge is established. Then, the curing agent formulas are optimized. After three-day conserving, the curing sludge could meet the landfill conditions.
