摘要
介绍了应用混凝沉淀/水解酸化/SBR工艺处理乳品废水的工程实例。该工艺占地面积小、运转费用低、管理方便、出水稳定、耐冲击负荷,出水水质可满足《污水综合排放标准》(GB8978—1996)的一级标准。工程实践表明,该工艺水解酸化段水力停留时间不宜超过5 h,提高有机负荷能有效抑制污泥膨胀,选择DO作为SBR池曝气时间和反应周期的运行控制参数是可行和有效的。
The engineering case of applying the coagulation and sedimentation/hydrolytic acidification/SBR process to treat dairy wastewater was introduced. The process has advantages of low land area,low running cost, convenient management, stable effluent and resistance to shock loading. The effluent quality can meet the Ⅰ-class criteria specified in the Integrated Wastewater Discharge Standard （ GB 8978- 1996）. The operation shows that the HRT of the hydrolytic acidification segment should not exceed 5hours, increasing organic loading can effectively inhibit the sludge bulking, and it is effective and feasible to select DO as the operational parameters of controlling SBR reaction and aeration period.
