NOVELTY - A composite biological flora comprises: Rheinheimera tangshanensis having preservation number of CGMCC No. 5972, Acinetobacter lwoffii having preservation number of CGMCC No. 5973, fluorescent pseudomonas comprising Pseudomonas fluorescens having preservation number of CGMCC No. 5974, and Wickerhamomyces anomalus having preservation number of CGMCC No.5975.    USE - As composite biological flora useful in biological liquid pulping application in paper making (all claimed).    ADVANTAGE - By using composite biological liquid for paper pulping, paper of more than AA level can be obtained. Further waste liquid generated in pulping process can be recycled, or can be used for conversion into marsh gas or organic fertilizer, which not only saves energy, but is also environment-friendly as marsh gas can be used for coal and gas fired heating boiler, which saves amount of coal used. Thus use of composite biological liquid for pulping paper does not pollute environment, but results in formation of organic fertilizer, this realizes zero waste discharge, and zero pollution, reduces reaction time for degradation of plant lignin to produce paper pulp, improves purity and yield of prepared fiber so that technique can be applied in large scale production. The biological pulping protects fibers, as compared to traditional chemical method. The method can utilize fibers including recycled fiber, and improves obtained slurry. In paper puling energy consumption is reduced 30% compared with traditional pulping, and pulp yield is increased by 20-25%. The biological pulping results in lignin-degradation, can be carried out under normal pressure, is energy saving, and has reduced emission of carbon. The production cost is low, and has high economic benefit. Thus process solves pollution problem of paper making industry, saves water, and improves utilization ratio of material.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for paper making process by using biological liquid involving: configuring composite biological flora in water solution, where weight ratio of Rheinheimera tangshanensis, Acinetobacter lwoffii, Pseudomonas fluorescens and Wickerhamomyces anomalus in liquid is 1-3:1-2:1-2:2-3, raw material processing that involves slicing woody cortex raw material or cutting herbal raw materials to sections, soaking cut raw materials into soaking pool for swelling, mitigating swelling of threads of raw material, crushing and/or grinding, soaking solution of raw materials in prepared biological liquid for biodegradation, sterilizing by draining raw material after biodegradation from liquid and steam sterilizing, grinding sterilized raw material for period for roughly grinding slurry to form fiber bundles, and fine grinding by putting first section of ground slurry for second section for thin grinding slurry, to make fiber bundles separated to single fibers, slurry screening involving filtering after latency period of fine grinding slurry of fiber bundles to form single fiber, and washing by soaking single fibers in warm water to prepare paper pulp.
