The invention discloses an effective paper deinking method. The effective paper deinking method includes the steps of primary cleaning, smashing, enzyme treatment, flotation and absorption treatment. The effective paper deinking method can be suitable for being used for conducting deinking treatment on waste corrugated paper, waste news paper, color offset printing news paper, waste book and magazine paper, waste office paper and laser and electrostatic printing paper; adopted deinking agents are biological enzyme and macroporous resin, the pH value of the whole treatment process is neutral, and no extra additive is needed to adjust the pH value, so that the cost is saved, the quality of waste paper pulp is improved, ink in sewage is adsorbed by the macroporous resin, the generated sewage is less, the water can be reused after being treated simply, resources are saved, the cost is lowered, and pollution to the environment is avoided; non-woven fabric is made of waste paper fiber, the macroporous resin can be reused after being regenerated, the price is chip, and the cost is saved; after waste paper is deinked, less fiber is lost, whiteness is high, speckiness is low, and reusability is high.
