摘　　要：以天津某包装纸业有限公司为例,分析包装废水的水质特点及其现有生产废水处理工艺存在的问题。采用“气浮+MBBR+臭氧”工艺替代现有污水处理设备,进水CODCr=1700~2000mg/L,处理后出水CODCr≤500mg/L,处理效率可达80%;进水BOD5=900~1200mg/L,处理后出水BOD5≤300mg/L,处理效率可达87%。处理后出水可达到《污水综合排放标准》(DB12/356—2018)中三级标准。Taking a packaging paper industry limited company in Tianjin as an example, this paper analyzes the water quality characteristics of the packaging wastewater and its problems existing in the production wastewater treatment technologies. The "air flotation + MBBR + ozone" technology is used to replace the existing sewage treatment equipment. When the influent CODcr = 1 700~2 000 mg/L and the treated effluent CODCr ≤ 500 mg/L, the treatment efficiency can be up to 80%. When the influent BOD5 = 900~1200 mg/L and the treated effluent BOD5 ≤300 mg/L, the treatment efficiency can be up to 87%. The treated effluent can be up to the three-level standard in Integrated Wastewater Discharge Standard (DB12/356-2008).
