摘要
介绍一种乳品加工废水处理技术———UASB +TF(滴滤床 )工艺。实际运行结果表明 ,该技术投入少、运行费用低、处理效率高。进水COD 10 0 0mg/L时 ,出水COD可以降到 6 0～ 80mg/L ,UASB水力停留时间 12h ,TF水力负荷 1m3 / (m2 ·h) ,出水可回用于冷冻机冷却循环用水。
UASB+TF process composed of upward anaerobic sludge bed and trickling filter was adopted to treat dairy processing wastewater. The investment and operating expenses of this process are low. The treatment effect of it is high. Under the condition when hydraulic retention time =12 h for UASB and organic load = 0 4 kg/(m 3·d) for TF, the COD level is decreased from 1 000 mg/L to 60～80 mg/L for inlet and effluent respectively. The effluent is reused as cooling water for refrigerating machine.
