| 摘 要： | 将冷轧过程产生的含油废水、脱脂平整废水、酸碱废水、生活污水、循环水排污水分流处理后收集,采用电催化氧化/MBR/反渗透进行深度处理并回用,处理水量为50 m3/h。工程实践表明,在实施有效预处理的条件下,出水水质优于《钢铁工业给水排水设计手册》中工业新水水质指标,废水处理成本为3.47元/m3,出水全部回用到循环水系统中,可节约工业新水消耗量为17×104 m3/a。

| Abstract: | After the oily wastewater,degreasing leveling wastewater,acid-base wastewater,sewage and circulating water discharge produced during cold-rolling are respectively treated and collected,the combined process of electric catalytic oxidation,MBR and RO is used for advanced treatment and reuse.The treatment capacity is 50 m3/h.The engineering practice shows that after the effective pretreatment,the effluent quality from the advanced treatment is better than the industrial new water quality index in Design Manual for Steel Industrial Water Supply and Wastewater.The wastewater treatment cost is 3.47 yuan/m3,all the effluent is reused in the circulating water system,and the industrial new water consumption of 17×104 m3/a is saved. |
