Straw biodegradation complex bacterial agent and application thereof

Abstract

The invention discloses a straw biodegradation complex bacterial agent. The complex bacterial agent is a compound of bacillus subtilis, bacillus amyloliquefaciens, bacillus cereus, phanerochaete chrysosporium and trametes versicolor. The invention belongs to the environmental-protection technology, a chemical pulping method commonly used in the current pulping technology is replaced by microbial degradation of plant straw, thus the environmental pollution caused by the use of a large number of chemical reagents in the traditional pulping process is avoided, in the production process of pulping, water can be recycled without discharging any sewage containing organic compounds and suspended solids, the link of sewage treatment is avoided, the production cost is saved, in the whole productionprocess, heating is not needed, decomposing is conducted at normal temperature, and bleaching is conducted at normal temperature. Meanwhile, the invention further discloses a preparation method and application of the straw biodegradation complex bacterial agent.

Description

technical field [0001] The invention relates to the technical field of straw degradation, in particular to a straw biodegradation composite microbial agent and its application. Background technique [0002] Straw cellulose is a very valuable biomass energy resource on the earth, which widely exists in various agricultural production systems. As a large grain-producing country, my country produces nearly 700 million tons of crop straw every year according to statistics. However, due to the lack of guidance and effective treatment methods, the problem of straw disposal has become increasingly prominent. Most of the disposal methods for straw are burning or discarding. This has also become a new source of rural environmental pollution. The current treatment of straw not only wastes precious renewable resources, but also brings various hazards, causing air pollution, soil mineralization, fires and traffic accidents. How to comprehensively and effectively use crop straw to avoid ...

Problems solved by technology

Pulping is the first process in the papermaking industry. At present, chemical pulping or chemical mechanical pulping methods are basically used in the world, mainly alkali method, ammonium sulfite method, etc. Therefore, the traditional pulping process is To a certain extent, it will be accompanied by the discharge of a large amount of black liquor waste, which seriously pollutes the environment

With the increasingly stringent environmental protection requirements, traditional pulp and paper enterprises need to invest a lot of cost to treat the sewage containing highly toxic and carcinogenic substances generated in the production process, which increases the production cost of the enterprise and reduces the quality of the enterprise's products. market competitiveness
