| 摘 要： | 大豆营养丰富,保健功能强,其蛋白质含量高达36%以上,而胆固醇含量极低,因此已成为人们摄取植物性蛋白的主要来源之一。为了提高国民素质,根据《中国食物结构改革与发展纲要》,中国己于1996年9月正式启动了大豆行动计划,发展大豆生产,积极引导消费,鼓励国民特别是中小学生饮用豆奶,食用豆制品。随着大豆计划的实施,豆制品生产的供与求将越来越大,相应地其废水排放量也越来越大,因此豆制品废水的处理显得十分紧迫1-4],采用厌氧好氧法处理模拟豆制品废水,考察曝气时间对厌氧处理后废水处理效果的影响。实验结果表明:进水COD为420 mg/L～580 mg/L,对废水中的COD、NH4+-N、PO34--P有较好的去除能力。该系统运行稳定,工艺可行。

| Abstract: | The soybean product wastewater treatment process was studied by anaerobic -aerobic method. The influence of aeration time on treatment effects for the effluent in anaerobic stage in SBR was investigated. The experimental results indicate that when the influent COD is 420 ～ 580 rag/L, the reactor has a good degeneration ability of COD, NH4^＋ - N and PO4^3- P. There- fore, the system is stable and the technology is feasible. |
