Background

The clearing and transporting amount of domestic garbage in China exceeds 1.8 hundred million t/a. Incineration treatment has been widely spread nationwide as an effective means for reduction. After the domestic garbage is burnt, slag with the burning amount of 20-25% is generated. After all domestic incineration power generation projects are put into operation, more than 2000 million of slag is expected to be generated every year. The timely and stable consumption of the slag becomes the key for ensuring the smooth operation of the household garbage incineration power generation project. At present, the domestic treatment of the slag mainly adopts a wet method, under the impact action of water, the recovery of valuable metals such as iron, copper, zinc and the like is realized, and the sorted slag is used for preparing the regeneration building block. However, the wet treatment has the problems of aluminum loss, high water consumption, large occupied area, high sludge and sewage yield, easy cracking of the regenerated building blocks and the like, so that the search of a novel slag treatment process technology is urgent.
