Specific implementation mode：
A kind of economical pressure type drinking water deep purification membrane-filtering unit maximum water consumption is about 6.5m3/h.The present apparatus is selected
With 3 inner pressed ultrafiltration membrane film columns, each film column membrane filtration area is 40m2, filtration flux selection 60L/hm2, a film column
Filtering water is 2.4m3/ h, 3 film column filtering waters are 7.2m3/ h, satisfaction are required with water.Water inlet manifold caliber is DN50, is gone out
Supply mains's caliber DN50.Film column backwash water flux is selected as 60L/hm2, the backwash flow of a film column is 2.4m3/ h, in addition just
Wash flow 2.4m3/ h, so, water flow when backwash in film column drainpipe is 4.8m3/ h, drain pipe diameter and main sewer pipe
Diameter is all DN50.Film column rinses once per filtration 120min, and 3 film columns rinse successively one by one, and a film is rinsed per 40min
Column, the perdurabgility that film column rinses are 2min.Water volume can be accommodated by choosing under maximum water pushing pressure be 0.2m3Pneumatic storage tank.
Flow of inlet water control valve, drain solenoid valve and drain discharge control valve are DN50.Diaphragm dosing pump selects 0~10L/h of flow,
Spray tank volume is 25L, and chemical feed pipe caliber is DN15, and dosing solenoid valve is DN15.
When operation, pressure raw water enters water inlet manifold 1, and bulk impurity is shut off by cartridge filter 2, intakes using film column
Pipe 3 enters film column 5, and the flow of inlet water control valve 4 on film column water inlet pipe 3 can quantify control amount of inlet water, and membrane filtration is kept to set
It is carried out under fixed flux.Water, through ultrafiltration membrance filter, removes the pollutants such as turbidity and the microorganism in water removal, then through film in film column 5
Column outlet pipe 6 flows into outfall sewer 7, sends to for users to use.After the mistake membrane filtration of film column 5 reaches the predetermined time, filter membrane is blocked by dirt,
Backwash need to be carried out, opens the drain solenoid valve 9 on film column drainpipe 8 at this time, since the outlet pressure of film column drainpipe 8 is very low,
Therefore the water after filter in outfall sewer 7 reversely flows into film column 5 and carries out backwash to ultrafiltration membrane, at this moment intakes and is also carried out simultaneously to filter membrane 5
Positive to rinse, the drain discharge control valve 11 on main sewer 10 can ensure that rinsing water flow reaches design value and keep constant.
After backwash 2min, drain solenoid valve 9 is closed, film column 5 restores filtration operation, only rinses a film column every time, and in 40min again
Other film columns are rinsed successively afterwards.In flushing process, water supply can be replenished in time in the pneumatic storage tank 12 on outfall sewer 7
Deficiency.For alleviate fouling membrane, can periodically simultaneously open and close diaphragm dosing pump, dosing solenoid valve and drain solenoid valve, to film column into
Row dosing is rinsed.
