equilibrium blast cupola

A kind of fly ash-based coagulant combining the capabilities of both physical adsorption and chemical coagulation has been prepared by adding a small amount of blast furnace iron sludge and an appropriate amount of helping solvent (HS) to fly ash in coal-fired thermal power plants and then the resulting mixture being stirred and extracted with a dilute H 2SO 4 for 2 h at 90℃.

笔者研究了在热电厂粉煤灰中加入少量的鼓风炉铁泥和适量的助溶剂HS ,在加热条件下用稀硫酸搅拌浸取 2h后 ,制得集物理吸附和化学混凝为一体的混凝剂。
