生产污水处理专用葡萄糖的生物发酵法:
The biological fermentation method of glucose for wastewater treatment is as follows
1、生物发酵法包括真菌发酵和细菌发酵,另外还有固定细胞发酵工艺。
1. Biological fermentation includes fungal fermentation, bacterial fermentation and fixed cell fermentation.
2、该方法是在240~300g/L的葡萄糖溶液中加入一定量的营养物质,,冷却适宜温度,接种体积分数为10%的黑曲霉种子液,开动搅拌,通气流,调整发酵液pH值维持在6.0~6.5,温度保持在32~34℃。发酵过程中滴加消泡剂,以发酵过程中所产生的泡沫。
2. The method is to add a certain amount of nutrients into 240-300g / L glucose solution, sterilize, cool to a suitable temperature, inoculate 10% Aspergillus Niger seed solution, start stirring, ventilate flow, adjust the pH value of fermentation solution to maintain 6.0-6.5, and keep the temperature at 32-34 ℃. In the fermentation process, defoamer is added to eliminate the foam generated during fermentation.
3、整个发酵过程约需20h,当残糖降1g/L时可以认为发酵结束,菌体与发酵液分离后,发酵液经真空浓缩、结晶可得葡萄糖酸钠晶体,或经喷雾干燥后制得工业葡萄糖粉产品。
3, the whole fermentation process needs about 20h. When the residual sugar is reduced to 1g/L, it can be concluded that the fermentation is finished. After separation of the bacteria and the fermentation broth, the sodium gluconate crystal can be obtained by vacuum concentration and crystallization, or the industrial glucose powder can be produced by spray drying.
随着科技的发展,生产工艺的进步,会有更多的方法会应用到污水处理专用葡萄糖的生产当中,届时大家可以根据需求选择合适的方法。
With the development of science and technology and the progress of production process, more methods will be applied to the production of glucose for sewage treatment. At that time, you can choose the appropriate method according to the demand.
