| Zusammenfassung: | The present invention relates to a method for manufacturing an inorganic coagulant using red soil. More specifically, the method includes the steps of: preparing red soil which is a by-product generated in a manufacturing process of aluminum hydroxide; leaching Fe_2O_3 from the red soil using an acidic solution; and manufacturing an inorganic coagulant by solid-liquid separating the acidic solution in which the Fe_2O_3 is leached.
본 발명은 적토를 이용한 무기응집제 제조방법에 관한 것으로, 보다 구체적으로는 수산화알루미늄의 제조공정에서 발생하는 부산물인 적토를 준비하는 단계; 상기 적토에 산성용액을 이용하여 Fe2O3를 침출시키는 단계; 및 상기 Fe2O3가 침출된 산성용액을 고액분리하여 무기응집제를 제조하는 단계를 포함하는 것을 특징으로 한다. |
