| titleOfInvention | Method for bleaching peroxide or ozone in chemical pulp |
| abstract | (57) [Summary] [Object] To provide a chemical pulp having a low Kappa number and a high whiteness in a peroxide or ozone bleaching method of the chemical pulp. [Structure] Before bleaching a chemical pulp with peroxide or ozone, the delignification reaction is promoted by the enzyme by the simultaneous treatment with the enzyme and the chelating agent in one step, or in each of the two steps. Trace metals are removed. [Effect] Compared with the conventional peroxide or ozone bleaching method, a chemical pulp having a low Kappa number and a high whiteness can be obtained. Furthermore, since there is no chlorine drainage in the previous stage, not only is the drainage load reduced, but it also leads to the reduction of environmentally problematic organic chlorine compounds. It is also possible to reuse white water. |
