味精生产废水主要来源于提取味精后的发酵废 液,浓缩结晶遗弃的结晶母液,以及各种洗涤、消毒废 水、废水外观呈黄褐色。发酵废液是一股极高浓度的 废水,一般每生产1吨味精约有25吨发酵废液排出, 这与发酵工艺、原料及菌种有关。发酵废液中含有2- 5％的湿菌体及蛋白质等固形物(菌体中富含蛋白质、 脂肪、核酸等营养物质),含有K+、Na+、NH4+、Mg2+、 Ca2+、Fe2+、CI-、SO42-、PO43-、等无机盐,消泡剂、色
MSG wastewater mainly from the extraction of MSG fermentation waste liquid, concentrated crystallization abandoned crystallization mother liquor, and a variety of washing, disinfection wastewater, waste water appearance was brown. Fermentation waste water is a very high concentration of wastewater, generally produce about 1 ton of MSG fermentation discharge of about 25 tons, which is related to the fermentation process, raw materials and bacteria. The fermented waste liquid contains 2-5% of wet cells and solid substances such as protein, fat, nucleic acid and other nutrients, and contains K +, Na +, NH4 +, Mg2 +, Ca2 +, Fe2 +, CI-, SO42-, PO43-, and other inorganic salts, defoamers, color
