The present invention discloses a method for preparing bisphenol A, comprising the following steps: transferring phenol and acetone into a reaction zone charged with condensation catalyst, obtaining a stream containing bisphenol A after reaction; transferring the obtained stream containing bisphenol A into a rectification zone, obtaining a product fraction primarily containing bisphenol A and phenol; and transferring the product fraction primarily containing bisphenol A and phenol into a crystallization zone to obtain a bisphenol A product; wherein a water-depleted fraction primarily containing phenol, bisphenol A and acetone is obtained from the rectification zone, and said water-depleted fraction is cooled and returned as a cycled stream to the reaction zone. Through cycling the water-depleted fraction to the reaction zone, the water content within the reaction zone can be reduced, the catalytic activity can be maintained and the reaction temperature rise can be controlled, thus the conversion of acetone and the selectivity of reaction can be improved accordingly.
