- 摘要:
- 针对传统超滤技术在自来水厂生产废水处理过程中存在的问题,设计研发了一种非浸没式超滤(NSUF)技术对水厂生产废水进行回用处理。通过考察和优化运行过程中膜通量与膜污染的关系,确定了较优的运行参数和清洗工况。中试结果表明,相较于传统卷式膜和管式膜,采用NSUF技术后出水水质稳定,对浊度的平均去除率为99%,产水浊度<0.03 NTU,产水各项指标均优于《生活饮用水卫生标准》(GB 5749—2022),平均产水率达98.5%。此外,通过扫描电子显微镜(SEM)对膜表面进行表征,发现膜污染情况较轻;NSUF技术处理成本约为0.238 元/m3。相较传统水厂生产废水回用处理技术,NSUF技术处理效能更高,运维成本更低,具有推广应用的前景。
- Abstract:
- In this study, a non-submerged ultrafiltration (NSUF) technology was designed and developed to facilitate the reuse and treatment of production wastewater from waterworks, providing references for solving the issues associated with traditional ultrafiltration technology in treating such wastewater. The optimal operating parameters and cleaning protocols were identified by systematically investigating and optimizing the relationship between membrane flux and membrane fouling during operation. Compared with traditional spiral-wound membranes and tubular membranes, the effluent quality remained stable upon employing NSUF technology in a pilot test. The average turbidity removal rate reached 99%, with the effluent turbidity being less than 0.03 NTU. Various indicators of effluent were superior to the values specified in Standards for Drinking Water Quality (GB 5749-2022), and the average water production rate was as high as 98.5%. In addition, the surface morphology of the membrane was characterized by scanning electron microscope (SEM), revealing that the membrane fouling was relatively mild. The processing cost associated with NSUF technology was approximately 0.238 yuan/m3. Compared to production wastewater reuse and treatment technologies in conventional waterworks, the NSUF technology demonstrates higher treatment efficiency and lower operation and maintenance costs, making it a promising candidate for widespread adoption and application.
