Municipal waste disposal system by high temperature smelting has the following characteristics: ① The smelting temperature is as high as 1 700-1 800 ℃; ② The dioxin is hardly produced; ③ The secondary pollution can be avoided because of the absence of heavy metals in the flux; ④ The metals and flux after disposal can be reused for construction materials. If outdated, the idle or discarded medium and small blast furnaces can be reconstructed into a waste resource system with high temperature smelting technique, and it is possible to make full use of their existing functions to reduce the investment and exploit their social function of environmental protection. In addition, a new waste disposal system with high temperature smelting was designed based on the recycling municipal waste technology abroad.
