Zusammenfassung:The invention discloses a method for synchronously and stably statically treating alkaline waste residues and urban sludge under interaction. The method has the advantages that synchronous and stablestatic treatment modes are adopted pertinently for the properties and characteristics of vulnerability to rotting and smelliness of sludge with the high content of organic matters and the strong alkalinity of furnace slag, the mixing ratio of the sludge to the furnace slag can be regulated and controlled, moisture can be regulated and controlled, ventilation can be controlled, accordingly, the sludge and the furnace slag can be synchronized and stabilized at a low cost, the degradation rate of the organic matters in the treated sludge can reach 40% at least, and the pH (potential of hydrogen)value of the furnace slag can be reduced and is lower than 8.4; the appearance of mixed materials stabilized by the aid of the method is similar to soil, and the mixed materials are free of optional undesirable odor and can be
