摘　　要：以自主研制的涤纶高弹丝纤维球为滤料,提出了微絮凝纤维球过滤-超滤-纳滤组合工艺处理综合回用洗浴废水的方法。试验结果表明,超滤出水可以回用至宾馆厕所冲洗、绿化等环节,纳滤出水可以回用至宾馆洗衣和洗浴等水质要求较高环节,同时研究发现,膜组件经复合清洗剂清洗后,水通量恢复率可达到99%以上。According to the water quality characteristic of hotel bath wastewater, a combined process including microflocculation fiber ball filtration, ultrafiltration and nanofiltration was developed by using self-developed fiber ball filter material composed of high stretch terylene yam. The results showed that effluent of ultrafiltration can be reused to lavatory flushing and virescence ere, and effluent of nanofiltration can meet high water quality requirements such as hotel washing clothes, bathing etc. Meanwhile, it found that the restoration ratio of membrane water flux could reach above 99% by using composite detergent.
