摘　　要：采用"预处理+超滤+反渗透"回用水处理组合工艺处理某印染行业二级生化出水。实验结果表明,原水经组合工艺处理后,出水水质达到回用水水质标准要求,可回用于生产;组合工艺中的核心处理单元为反渗透系统,在反渗透系统进水流量为35 L/min时,反渗透系统最佳运行工况为操作压力1.2 MPa、浓水循环流量5 L/min,反渗透系统回收率约为80%;组合工艺水处理成本约为2.2元/m3,较生产用自来水成本低,同时出水水质优于自来水,具有较好的经济效益和广阔的应用前景。The combined technology ＂pretreatment ＋ UF ＋ reverse osmosis＂ is used for treatmem of secondary biochemical westewater in printing and dyeing industries. Experimental results indicates that, after the treatment of the raw water by combined process, water quality meets water reuse requirements and it can be used in production; the core processing unit in the combined process should be anti - penetration system and when water flow is 35 L/win, operation pressure 1.2MPa and concentrated water cycle flow 5 L/min, water recovery rate will be about 80% ;the treatment cost is about 2.2 Yuan/m3,lower than tap water omt, meanwhile water is better than tap water, so with better economic benefits and broad application prospects.
