This FIG. 1 is a flow chart of an emergency water purifier, which mainly comprises a raw water pump 1, a prefilter 2, a permeable membrane module 3 such as a microfiltration membrane or an ultrafiltration membrane, and a disinfection facility 4. , A permeate tank 5, and a backwash pump 6.

る。The raw water sent from the water source 7 to the prefilter 2 via the raw water pump 1 and pretreated by the prefilter 2 is suspended by the permeable membrane module 3 in addition to suspended substances,
Almost all general bacteria, Escherichia coli, etc. are removed, and the permeated water is guided to the permeated water tank 5 to which the disinfectant is supplied from the disinfection equipment 4 through the pipe line 8 and disinfected, and the purified water is supplied as drinking water.

出することにより、低負荷運転を行なうのである。The concentrated water discharged from the permeable membrane module 3 is discharged to the outside of the system through the pipe 9.
That is, in order to keep the permeable membrane module 3 high,
In the present invention, the raw water that has passed through the pre-filter 2 is passed through the permeable membrane only once, because the transient treatment method is more preferable than the circulation method in which the circulating water concentrated by cross flow filtration is treated many times. The low-load operation is performed by treating the concentrated water with the module 3 and discharging the concentrated water out of the system.

に圧送することにより行なわれる。The backwash of the permeable membrane module 3 is carried out by backwashing the permeated water in the permeate tank 5 with the backwash pump 6.
It is carried out by pumping to.

緊急用浄水装置として好適である。As described above, according to the present invention, since the flux of the permeable membrane is kept high by the cross flow filtration transient type treatment system, and the water receiving tank and the circulation tank are not required, a large apparatus is provided. It is suitable as a water purification device for emergency in the event of a disaster because it can be made compact and the device can be easily transported and installed locally.
