Beschreibung
Zusammenfassung:	The invention discloses a method for the filtering separation of sodium aluminate pulp. In the method, sodium aluminate pulp passes through a settling tank, a middle washing and settling tank and a final washing and settling tank in turn, red mud obtained after washing and separation is delivered to an effluent tank to be separated with the aid of a filter. In the invention, a settling tank washing system and filteration technology are combined and the overall load of the settling tank washing system is reduced, so the consumption of flocculant is effectively reduced, the treatment capacity and efficiency of the settling tank washing system are improved, and the drawbacks in the prior art are overcome.
