乳品生产废水处理

介绍了混凝沉淀-水解酸化-SBR工艺处理乳品生产废水的设计、调试、运行情况以及主要工艺设备。运行结果表明,在进水的SS、CODCr、BOD5、NH3-N的质量浓度分别为300～1000、800～3000、350～1500、25～70mg/L时,其处理出水的SS、CODCr、BOD5、NH3-N的平均质量浓度分别为7、12.29、1.78、9.3mg/L,达到了污水综合排放标准(GB8978-1996)的一级标准。该工艺具有占地面积小,处理效率好,运行费用低等特点,能广泛应用于乳品生产废水的处理。

A project case of treatment of wastewater from dairy production

The design,debugging,operation condition and main equipments for coagulation sedimentation-hydrolytic acidification-SBR technology in treatment of wastewater from dairy production were introduced.The running results showed that,when the mass concentration of SS,CODCr,BOD5,NH3-N in influent water were 300 ~ 1 000,800 ~ 3 000,350 ~ 1 500,25 ~ 70 mg/L respectively,after the treatment,the average mass concentration of the thoese matters in effluent water were 7,12.29,1.78,9.3 mg/L respectively,which met the specification for grade 1 in Integrated Wastewater Discharge Standard(GB 8978-1996).The said process has the features of less site area,good treatment efficiency,low operation costs and so on,which can be wildly used in treatment of wastewater from dairy production.
