Description
Technical field
The present invention relates to bast fibre spinning technical field, particularly relate to a kind of method of biological degumming of ramie kiering (high-temperature sterilization) wastewater utilization.
Background technology
Ramee is a characteristic resources of China, and its fiber product has moisture absorption rapid heat dissipation, breathes freely, not next to the skin, antibacterial, the well-pressed advantage such as attractive in appearance, is high-grade natural fibre product.Except containing except Mierocrystalline cellulose in ramie crop bast, also containing some impurity, comprise the compositions such as pectin substance hemicellulose.These colloids are enclosed in the appearance of fiber, by sheet harder for formation cemented together for fiber fiber crops bundle.Such fiber crops bundle can not directly be used for spinning.Therefore degumming process must be imposed to raw ramie before the processing of spinning.China grass degumming is the foundation works of textile processing chain, and the degummed ramie fiber quality obtained after coming unstuck has a significant impact textiles wear behavior.
Traditional degumming technology is chemical method, carries out kiering with caustic soda, the process of auxiliary acid and oxygenant, and the process of physical method, realizes coming unstuck to ramie.But the method severe reaction conditions, labour intensity is large, big energy-consuming, and production cost is high, and environmental pollution is serious, and has certain damage to fiber, and make ramee mixed and disorderly, comb spins processing difficulties, and fiber row yielding is low.In order to reduce the production cost of China grass degumming, improve the quality of flaxen fiber, prior art has developed ramie biological degumming technology.Biological degumming is that the degumming strain through screening is inoculated on raw ramie, these degumming bacteriums with the colloid on ramie for nutrition source, amount reproduction on raw ramie, secretion degummase decomposes colloid, makes the macromole such as the pectin of high molecular and hemicellulose resolve into small-molecule substance and water-soluble.This is a kind of under mitigation condition, the biochemical reaction of a series of " the glue bacterias, bacterium produces enzyme, and enzyme comes unstuck " that carry out.Ramie biological degumming technology is the technology utilizing microorganism to produce degummase fast degradation ramie gum components, and its treatment condition are gentle, pollution-free, can improve flaxen fiber quality, reduces production cost.Compare with chemical Degumming, because biological degumming of ramie is the colloid in degummase directional catalyzing degradation of fibers, under can eliminating strong acid, highly basic and high temperature, highly basic is to the negative interaction of fiber, improves fiber row yielding and reaches 2% ~ 4%, residual gum content low (≤2%).
In the prior art, the technical process of biological degumming of ramie comprises preparation and the China grass degumming of bacterium liquid, especially with large in degumming boiling-off (high-temperature sterilization) waste liquid amount, organic component is complicated, need comparatively it directly to be discharged after great achievement present treatment.Prior art discloses the multiple treatment process to biological degumming of ramie waste water.As the SBR art breading kenaf fibers retting wastewater such as Zhang Shenghong, collect water inlet, reaction, to precipitate and draining completes in a pond, have that technique is simple, automatization level is high and the feature such as saving occupation of land.In SBR, anaerobism, anoxic and aerobic environment alternately occurs, the open loop or the chain rupture that are conducive to refractory organic are converted into degradable substance, Controlling System oxygen supply can realize denitrogenation dephosphorizing (Zhang Shenghong, Chen Jihua, Liu Zhenhong. SBR method process kenaf fibers retting wastewater. Environmental Pollution and Control, 2001,23 (1): 64 ~ 68.).Gao Chunmei etc. utilize membrane bioreactor to process ramie-degumming waste water, find by carrying out detection to chemical oxygen demand (COD), ammonia nitrogen, suspended substance and colourity in waste water, effluent quality reaches national comprehensive discharge standard (Gao Chunmei, Xi Danli, Yang Xiaobo. the research of Membrane Bioreactor for Wastewater Treatment ramie-degumming waste water, Environmental Pollution and Control, 2005,27 (8): 583 ~ 587.).
Above-mentioned these can make it reach national comprehensive discharge standard to the treatment process of biological degumming of ramie waste water, can not to environment after discharge, but its complex treatment process, working cost is large, be discharged into after it is processed in environment, do not have to reuse water resources, cause the wasting of resources.
