摘要
制革废水属于高浓度有机废水之一,其处理难度较大。本废水处理工艺采用二级VTBR生化塔接触氧化工艺处理制革废水,具有投资少、占地面积小、运行费用低、处理效果好、抗水质变化冲击能力强、操作简便等特点。废水经过处理后完全达到DB21-60-89一级排放标准,为制革废水的治理提供了一条有效途径。
The tannery wastewater is one of the organic wastewater of high concentration and the treatment is difficult. The title process involves the wastewater treatment facilities as the use of two-tower VTBR contact oxidation process of biochemical treatment of tannery wastewater. It has many advantages such as the lower investment, limited covering area, lower operation costs, effective treatment, better anti-change impact on water quality, easy operation and so on. After the treatment,the wastewater passed the drainage standard DB21 -60- 89. The treatment process provides the tannery wastewater treatment with an effective way.
