针对豆制品生产废水排放的环境影响问题,提出了一种基于生物滤膜污水处理法来处理富含蛋白质、油脂及碳水化合物的豆制品废水。方法利用细小孔径的超滤膜分级处理高分子量蛋白质,同时结合活性炭和沸石来去除Ca、Mg和NH4等物质,通过对工厂废水的处理结果进行分析,证明了生物滤膜污水处理法的正确性和有效性。 In view of the environmental impact of the wastewater from the production of soy products, a biofilter-based wastewater treatment method was proposed to treat the soy protein wastewater containing protein, grease and carbohydrates. Methods High-molecular-weight protein was fractionated by using ultrafiltration membrane with small pore size. Activated carbon and zeolite were combined with activated carbon and zeolite to remove Ca, Mg and NH4. The correctness of the biofilter wastewater treatment method was proved by analyzing the treatment results of the wastewater from the factory. And effectiveness.
