摘要
利用二级厌氧生物滤池结合曝气生物滤池工艺处理大豆加工废水,运行表明,经炉渣过滤、混凝过滤、二级厌氧生物滤池、曝气生物滤池、深度过滤后,废水COD质量浓度由4×104 mg/L下降到118 mg/L左右,达到了二级排放标准的要求。同时能回收部分产物作饲料。
Soybean wastewater has been treated by two-stage anaerobic biofilter combining with biological aerated filter. The result shows that COD concentration is reduced from 4× 10^4 mg/L to 118 mg/L which is up to the Second Discharge Standard after the treatment by cinder filtration, coagulation/sedimentation, two-stage anaerobic biofilter, biological aerated filter and deep filtration. At the same time some products can be recycled as fodder.
