Method for producing bleached pulp for papermaking |
| abstract |
An object of the present invention is to provide a method for reducing chlorine dioxide at a low cost and efficiently and economically performing chlorine dioxide bleaching without using environmentally harmful chemicals such as formaldehyde. The present invention provides a method for producing pulp having a high pulp content. A bleaching method comprising treating a pulp made from a lignocellulosic material as a raw material in (a) an alkali oxygen bleaching step and (b) an enzyme treatment step, and thereafter (c) subjecting the pulp to ECF bleaching with a chlorine dioxide stage as a first stage. A method for bleaching a lignocellulosic material, comprising obtaining a permeate from the reaction filtrate obtained by the enzyme treatment step by a membrane filtration method, and adding at least a part of the permeate to a chlorine dioxide bleaching stage.
