Pulp from the pulp strength properties and to eva luate, bamboo paper is a better raw materials, second only to coniferous wood, close to broad-leaved trees. With the development of paper industry, for cooking and the use of oxygen and hydrogen peroxide bleaching, such as new non-polluting methods, new technologies replace the traditional bamboo and conventional batch cooking chlorine bleaching of pulp and technology is the goal of modern bamboo plant. On behalf of a bamboo wood, paper industry in order to reduce the demand for wood raw material pressure to adapt to the requirements of ecological and environmental protection for the bamboo paper provides a broad development opportunities. This paper analyzes the old and the new chemical composition of the bamboo content and, through cooking, compare new and old bamboo the cooking characteristics of bamboo. The experimental results show that the cooking properties of the new bamboo was significantly higher than the old bamboo, and activation degree of the more high, the better the performance of their cooking. pulp copied to create a more clean and contained fewer impurities. in the same degree of activation, the higher the temperature, the longer the cooking, the cooking, the better also. the end of two under the conditions of different degrees of activation were pulp bleaching, experiments show that activation of its high effective bleaching, and under the same conditions, the bleaching effect of the new bamboo is superior to the old.

The use of waste paper resources at home and abroad more and more paper industry occupies an important position paper on China's such a lack of raw materials for paper industry is more far-reaching significance. The design specification includes the following elements: First, to introduce the engineering design background, the need for engineering design; II introduces the conditions for process design and general layout, as well as a general layout of the basic principles and outlines the general layout; Third, some technology, but also the focus of this design shows that the production process and serofluid balance calculation, equipment selection, the shop layout, and production flow chart drawing, workshop floor plan, equipment list; IV introduced the design aided engineering workshop facilities. The last part stated references,and Expressed my gratitude to teacher for her help. Keywords:wasted peper pulping; Process Design; Production process
