生產污水處理專用葡萄糖的生物發酵法：
The biological fermentation method of glucose for wastewater treatment is as follows
1、生物發酵法包括真菌發酵和細菌發酵，另外還有固定細胞發酵工藝。
1. Biological fermentation includes fungal fermentation, bacterial fermentation and fixed cell fermentation.
2、該方法是在240～300g/L的葡萄糖溶液中加入一定量的營養物質，滅菌，冷卻至適宜溫度，接種體積分數為10%的黑曲霉種子液，開動攪拌，通氣流，調整發酵液pH值維持在6.0～6.5,溫度保持在32～34℃。發酵過程中滴加消泡劑，以消除發酵過程中所產生的泡沫。
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、整個發酵過程約需20h,當殘糖降至1g/L時可以認為發酵結束，菌體與發酵液分離后，發酵液經真空濃縮、結晶可得葡萄糖酸鈉晶體，或經噴霧干燥后制得工業葡萄糖粉產品。
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.
隨著科技的發展，生產工藝的進步，會有更多的方法會應用到污水處理專用葡萄糖的生產當中，屆時大家可以根據需求選擇合適的方法。
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.
