大豆分离蛋白工艺废水厌氧生物净化的研究

Study on Anaerobic Purification of Waste Water from Soybean Protein Isolated

大豆分离蛋白工艺废水是高浓度的有机废水，其中丰富的碳水化合物、蛋白质、氨基酸、氮和磷等营养物是厌氧菌生长的良好条件。用厌氧生物净化法净化此工艺废水，可使净化效率达到９３％ 以上。在净化废水、保护环境的同时可生产沼气，回收能源。

Waste water from production of soybean isolated proteins was highly organic water.It contained plenty of hydrocarbon,protein,amino acid and other nutritious substances containing nitrogen and phosphorus.It was beneficial to anaerobe.The purificial to anaerobe.The purification rate could amount to more than 93% by anaerobic method.Moreover,the process produced biogas and recovered energy.
