A kind of compound enzyme preparation and the technology for preparing paper pulp

Abstract

The invention discloses a complex enzyme preparation. The complex enzyme preparation is prepared from 10-20 parts of laccase, 10-15 parts of xylanase, 3-5 parts of pectinase and 1 part of mannose. According to the complex enzyme preparation, the problem that in the prior art, the period for treating plant fiber raw materials by adopting microorganisms is too long is solved. The invention further discloses a process for preparing paper pulp by adopting the above complex enzyme preparation, and a bio-enzyme method is adopted to combine with mechanical pulping.

Description

technical field

[0001] The invention belongs to the technical field of compound enzyme preparations, and relates to a compound enzyme preparation and a process for preparing pulp by using the compound enzyme preparation. Background technique

[0002] The environmental pollution of the paper industry has been widely concerned by people. The traditional pulping production processes mainly include alkaline pulping, ammonium pulping, lime pulping, sodium nitrite pulping and blasting pulping. These traditional pulping techniques use a large amount of chemical raw materials to extract lignin pulp in wood, stalks, rice straw, reeds, and bamboo. During the cooking process, a large amount of chemical residues and reactants are produced, and a large amount of black liquor pollutants are generated, which increases the investment in effluent treatment and increases the cost of papermaking. The subsequent bleaching process uses a large amount of chlorine-containing oxidative bleaching a...
