Abstract
The present disclosure relates to a method for preparing an unbleached biomechanical pulp and fully utilizing by-products by treating wheat straws with heat steam in synergy with biological enzymes, which belongs to the technical field of papermaking technology and waste comprehensive utilization. The present disclosure provides a method for preparing an unbleached biomechanical pulp by treating whole wheat straws with heat steam in synergy with biological enzymes, where the prepared high-strength biomechanical pulp can meet the requirements of producing unbleached packaging paper and paper-based materials. At the same time, the by-products are recycled to prepare a biomass compound fertilizer, which turns solid waste into treasure and realizes the high-value full utilization of wheat straw. Therefore, the method in the present disclosure is simple, green, clean and efficient, which has good practical application value and broad application prospects.
