Sewage zero discharge treatment method and device for filter production line

The invention discloses a sewage zero-discharge treatment method and device for a filter production line, and belongs to the field of wastewater treatment. The treatment method comprises the following steps: S1, oil separation treatment; s2, coagulation and air flotation; s3, softening and coagulating; s4, ozone oxidation; s5, adsorbing and filtering; the sewage of the filter production line comprises 0.21 mg/L to 1.11 mg/L of iron, 0.05 mg/L to 0.24 mg/L of zinc and less than 0.05 mg/L of nickel. The sewage zero-discharge treatment method for the filter production line provided by the invention has no biochemical treatment step, avoids the influence of heavy metals on biochemical treatment, is simple to operate and stable in daily operation, and ensures that the effluent quality can meet the water quality of industrial water for recycling urban sewage. 本发明公开了一种滤清器生产线污水零排放处理方法及装置，属于废水处理领域。该处理方法包括步骤：S1.隔油处理；S2.混凝气浮；S3.软化混凝；S4.臭氧氧化；S5.吸附及过滤；S6.纳滤，所述滤清器生产线污水包括铁0.21～1.11mg/L、锌0.05～0.24mg/L、镍＜0.05mg/L。本发明提供的一种滤清器生
