    • The wastewater treatment system according to the present invention includes a plurality of reaction sequences including a first sedimentation tank, a reaction tank, a final sedimentation tank, a first channel which connects the first sedimentation tank and the reaction tank and a second channel which connects the reaction tank and the final sedimentation tank. In one reaction sequence of the plurality of reaction sequences, the reaction tank has a membrane separation tank including a carrier, a membrane unit, and activated sludge and in which an MLSS concentration of the activated sludge is in a range of 500 mg/L to 7000 mg/L, and wastewater is supplied to the reaction tank via the first channel, and wastewater in a quantity exceeding a treatment capacity of the reaction tank is supplied to the final sedimentation tank via the second channel.
    • 根据本发明的废水处理系统包括多个反应序列,包括第一沉淀池,反应罐,最终沉降槽,连接第一沉淀池和反应罐的第一通道和连接第一沉淀池的第二通道 反应罐和最终沉淀池。 在多个反应顺序的一个反应顺序中,反应槽具有包括载体,膜单元和活性污泥的膜分离罐,其中活性污泥的MLSS浓度在500mg / L至 7000mg / L,废水通过第一通道供给反应槽,超过反应槽处理能力的废水通过第二通道供给至最终的沉淀池。

    • To reuse support plate and to fix a membrane sheet by the same method both in a new product manufacturing and in regeneration. In a flat membrane element 10 including a deposit fixed portion 18 formed by lapping a membrane sheet 14 performing solid-liquid separation onto a support plate 12 supporting the membrane sheet 14 and by emitting a laser to a circumferential edge of the membrane sheet 14 to deposit fix the member sheet 14 onto the support plate 12, and making an inside of the membrane sheet 14 surrounded by the deposit fixed portion 18 be a solid-liquid separating area 20; an embrocation 22 having laser absorption property is applied on the surface of the membrane sheet 14 of the deposit fixed portion 18. At the time of regeneration, such a portion of the membrane sheet 14 that corresponds to the solid-liquid separating area 20 is cut off and, after that, a new membrane sheet is lapped on the embrocation 22 and the new membrane sheet and the embrocation 22 are deposit fixed by a laser.
    • 在新产品制造和再生中,通过相同的方法重新利用支撑板和固定膜片。 在包括通过将进行固液分离的膜片14研磨到支撑膜片14的支撑板12上并通过向膜片14的周缘发射激光而形成的沉积物固定部分18的平膜元件10中, 将构件片14固定在支撑板12上,使由沉积物固定部18包围的膜片14的内部成为固液分离区域20; 在沉积固定部分18的膜片14的表面上施加具有激光吸收特性的插入件22.在再生时,与固液分离区域20对应的膜片14的这一部分被切割 然后将新的膜片层叠在穿孔22上,新的膜片和穿孔22通过激光固定。
