| 摘要 |
The present invention relates to a pressurized membrane filtration system using a submerged membrane filtration process, which removes turbid materials from cohesion water using a hydrocyclone and treats concentrated water discharged from the hydrocyclone and discharged water discharged from a pressurized membrane filtration module, and also to a purified water treating method using the pressurized membrane filtration system. According to the present invention, at least 90% of turbid material entering into the pressurized membrane filtration module is removed by the hydrocyclone, so driving can be performed without a reduction in filtration flow rate of a pressurized membrane filtration process and recovery rate and the transmembrane pressure stability of a membrane filtration water purification process can be improved. Furthermore, a submerged membrane filtration process is introduced, so high-concentration turbid material in hydrocyclone concentrated water and discharged water discharged in the pressurized membrane filtration process can be filtered out. |
