双膜处理技术应用存在的问题及注意事项

Problems existing in application of double membrane treatment technology and matters needing attention

对双膜处理技术在水处理领域易出现的问题进行归类分析、总结和评价,提出生产过程中的注意事项和评价方法,发挥双膜处理技术优势,提供科学管理方法和污染物控制措施。为保证双膜系统正常运行,在做好原水指标控制同时,关注双膜系统的流量、压力、压差的变化,以保证双膜系统在可控的工艺指标运行,实现科学管理和污染物得到有效控制的目的。

This paper conducted the classification,analysis,summarization and evaluation on the problems that were likely to occur in the field of water treatment with double membrane treatment technology,put forward the matters for attention and evaluation methods in the production process in advance,gave full play to the advantages of double membrane treatment technology,and pro⁃vided scientific management methods and pollutant control measures.In order to ensure the normal operation of the double mem⁃brane system,we should pay attention to the changes of the flow rate,pressure and differential pressure of the double membrane sys⁃tem while controlling the raw water index,so as to ensure the operation of the double membrane system under the controllable tech⁃nical index and realize the purpose of scientific management and effective control of pollutants.
