摘要:
温州某皮革厂针对生产用水消耗大、重复利用率要求高的问题，采用水解酸化+两级AO+MBR工艺处理经过精馏/脱酸处理后的冷凝水（含有N，N-二甲基甲酰胺，即DMF），平均出水COD为56 mg/L、氨氮为0.5 mg/L、TN为3.5 mg/L、悬浮物为0.5 mg/L、色度为8倍，满足皮革厂对回用水水质的要求。将该工艺产水回用至生产车间凝固槽作为补充水，实现对冷凝水的100%重复利用率。整个项目自建成运营以来，废水处理效果稳定，实际处理水量为360 m3/d，工程建设费用为950万元，处理费用为9.05元/m3，具有一定的环境效益和经济效益。
Abstract:
In response to the high water consumption and high requirements for water reuse in leather factory production, we use the hydrolysis acidification+two-stage AO+MBR process to treat the condensed water containing DMF after distillation/deacidification treatment from a leather factory in Wenzhou. The average concentration of pollutants in the process water is: COD 56 mg/L, NH3-N 0.5 mg/L, TN 3.5 mg/L, SS 0.5 mg/L, and the chromaticity of 8 times. The effluent quality meets the requirements of the leather factory owner for recycled water quality. Reusing the process water to the solidification tank in the production workshop as supplementary water achieved a 100% reuse rate of condensed water. Since the completion and operation of the project, the wastewater treatment effect has been stable, with a actual processing water volume of 360 m3/d, the construction cost is 9.5 million yuan, and the water treatment cost is 9.05 yuan/m3, which has certain economic value and environmental benefits.
