Description: The invention discloses a clean papermaking technology and a paper cup preparation method, and the method comprises the following steps: pulping: feeding raw materials into a sizing machine, adding water, crushing to form pulp water, and then filtering pulp blocks in the pulp water to prepare coarse pulp for later use; pulp purification: feeding the coarse pulp into a separator, and filtering the coarse pulp through a group of screens from large to small, so as to obtain fine pulp for later use; and deinking: conveying tiny bubbles into the paper pulp through an aeration machine. The invention relates to the technical field of papermaking and paper cup preparation. A pure mechanical method is used for replacing a traditional chemical papermaking technology, waste paper and straw are adopted as raw materials, the pressure of forestry felling can be avoided on the raw materials, no chemical agent is added in the preparation process, the emission pollution situation can be reduced, meanwhile, used water can be r
