The bio-degumming method focused research interest on green degumming technology in the textile sector, addressing environmental pollution, water usage and energy consumption caused by chemical degumming methods while enhancing fiber quality. The application of recent developments in the chemical degumming method of fiber remains a challenge for environmental protection. The novel spiral symmetry stream anaerobic bioreactor was employed in a system that integrates the ramie degumming process and reduces wastewater generation. This study analyzed the effect of liquor ratios on the water quality indicators, fiber quality and microbial community composition. After this study, the effluent chemical oxygen demand concentration, pH and ammonia nitrogen were 264.2 ± 114.2, 7.2 ± 0.1 and 7.4 ± 4.8 mg/L, respectively. This shows a mean chemical oxygen demand removal rate of 55.7 ± 11.8%, which is over 79% higher than previous bio-degumming methods. The fiber quality met the ramie fine dry hemp standard requirements. The high-throughput sequencing results revealed that the microbial community adapted to this process. The relative abundance of dominant microbes ( Bacteroidetes and Methanosaeta), which perform biodegradation and methane production, was present. This study demonstrates a promising green degumming technology and eco-friendly concept for the textile industry.

使用集成螺旋对称流厌氧生物反应器对苎麻纤维进行生物脱胶

生物脱胶法重点研究纺织领域的绿色脱胶技术，解决化学脱胶法造成的环境污染、用水和能源消耗，同时提高纤维质量。纤维化学脱胶方法的最新进展的应用仍然是环境保护的挑战。新型螺旋对称流厌氧生物反应器应用于集成苎麻脱胶工艺并减少废水产生的系统中。本研究分析了浴比对水质指标、纤维质量和微生物群落组成的影响。研究后出水化学需氧量浓度、pH值和氨氮分别为264.2±114.2、7.2±0.1和7.4±4.8 mg/L。这表明平均化学需氧量去除率为 55.7 ± 11.8%，比以前的生物脱胶方法高出 79% 以上。纤维质量满足苎麻细干麻标准要求。高通量测序结果表明微生物群落适应了这一过程。存在相对丰富的优势微生物（拟杆菌门和甲烷菌门），它们进行生物降解和甲烷生产。这项研究为纺织工业展示了一种有前景的绿色脱胶技术和环保理念。
