Cross-flow valve 5, using the cross-flow valve of the ZS-25 model of three power of Yuyao letter production, brass material is made, closed type.
Intake valve 8, using the 270D97A1XN-10Q-40 of the good benefit production in Beijing, the material of valve is magnesium iron body, valve
Valve plate uses nylon coating, is rubber on valve body；
The LW2-0960-F that ultra-filtration membrane device 6 is produced using Hainan liter, PVDF material are made, effective membrane area 55m2。
The course of work of the utility model is as follows:
When normal water running processed, the sewage of qualified discharge enters sewage inlet 17 via raw water pump 1, squeezes into bag type filtering
In device 2, bulky grain suspended matter is removed, the water outlet of bag filter 2 enters in ultra-filtration membrane device 6 by inlet valve 3, by ultrafiltration membrane
Device 6 filter after, a part of waste water become produce water through production water valve 10 flow into water producing tank 16 in, another part contain suspended matter,
The waste water of the impurity such as organic matter is discharged by cross-flow valve 5, (does not make marks in figure) into raw water sewage disposal system.
The every operation of ultra-filtration membrane device 6 30 minutes, needs to carry out a backwash process, backwash step automatically are as follows:
(1) gas is cleaned
System can cut off original normal water transport line program processed, clean into gas, first open upper valve 4, then open air inlet
Valve 8, and it is passed through oil-free compressed air, air enters entire ultra-filtration membrane device 6, wipes air and the water of ultra-filtration membrane device 6
It washes, forms turbulent flow, air together rubs to film wire surface with water during rising, the pollution of such film surface covering
Object is just washed down, and intake valve 8 is closed after duration 60s, 60s, opens lower valve 7, the dirt split away off is arranged
System out, draining duration are 40s, after the discharge of the water of lower valve 7 is clean, close lower valve 7；
(2) water backwash
Water backwash is divided into backwash, lower backwash again and just washes.
Backwash valve 9 and upper valve 4 are first opened when upper backwash, then opens backwashing pump 15, and backwashing pump 15 is straight from water producing tank 16
It connect to draw water and squeezes into entire ultra-filtration membrane device 6, the upper backwash duration is 40s；
Lower valve 7 is opened after 40s, simultaneously closes off valve 4, and the lower backwash duration will be 60s；
Backwashing pump 15 is closed after 60s, turns off backwash valve 9 and lower valve 7, into just washing, first opens inlet valve 3 and upper row
After valve 4, then raw water pump 1 is opened, raw water pump 1 is directly drawn water from the sewage of qualified discharge by sewage inlet, is squeezed into entire
Ultra-filtration membrane device 6, just washing the duration is 60s, and normal water running step processed is reentered after 60s.
Under normal circumstances, ultra-filtration membrane device 6 can according to normal water running step processed and water backwash step alternate run, every 30
Minute carries out a backwash, but backwash is not thorough every time, can all have polluter residual on the surface of the film, under multiple periods
It goes, will result in water yield decline, in order to avoid such case generation, it is necessary to primary restorative cleaning is carried out within every 12 hours,
2 times a day, primary acid restorative cleaning, primary alkali sterilize restorative cleaning.Also just delay offline chemical cleaning in this way,
Labour is saved, is improved work efficiency.Specific step is as follows for acid restorative cleaning and the restorative cleaning of alkalinity sterilization:
(1) acid restorative cleaning
Because may colloid or suspended matter containing high-valency metals such as iron, aluminium in water inlet, it is also possible to which there are hardness etc. to tie
Dirt tendency, these impurity may cause the inorganic matter pollution of ultrafiltration membrane, therefore when the progress restorative cleaning of acidity, acid group used
It is general to select 0.1% hydrochloric acid depending on specific raw water quality situation, can with the colloid and calcium carbonate of metal oxide and
Magnesium carbonate, which directly reacts, forms metal chloride, and such ultra-filtration membrane device 6 can be cleaned.Hydrochloric acid is in hydrochloric acid chemicals dosing plant
It is configured in 12, and pipe-line mixer 11 is pumped by metering pump 19.When 12 liquid level of hydrochloric acid chemicals dosing plant is lower, metering pump
19 stop working.
It needs to carry out to cut off entire water program normally processed when acid restorative cleaning, cleans step into gas, and then beat
After opening backwash valve 9 and upper valve 4, backwashing pump 15 is opened simultaneously, backwashing pump 15 directly draws water from water producing tank 16, opens simultaneously salt
Sour chemicals dosing plant 12 squeezes into entire ultra-filtration membrane device 6 after pipe-line mixer 11, and the duration is about 60s, works as PH=2
Afterwards, backwash valve 9, upper valve 4, hydrochloric acid chemicals dosing plant 12, backwashing pump 15 are simultaneously closed off, and impregnates 15-30min, immersion terminates
Enter a backwash step afterwards.
(2) alkalinity sterilizes restorative cleaning
After backwash step, carry out alkalinity and sterilize restorative cleaning, when high organic content in water inlet, organic matter and
Active bio can cause the pollution of ultra-filtration membrane device 6, and the organic matter in raw water is the major reason polluted, and works as condition
When being conducive to biological existence, some bacteriums and algae will also breed in ultra-filtration membrane device 6, thus cause biological pollution.At this
In embodiment, alkalinity is carried out using the confection of+0.1% sodium hypochlorite of 0.05% sodium hydroxide and sterilizes restorative cleaning, because
Bacterium and algae can be directly killed for sodium hypochlorite, and sodium hydroxide has the work of certain chelation cleaning to organic matter
With, therefore can solve the problem of organic matter and active bio pollute using above-mentioned confection.0.05% sodium hydroxide and
0.1% sodium hypochlorite is configured in sodium hydroxide chemicals dosing plant 13 and sodium hypochlorite medicine adding device 14 respectively, and passes through meter
Amount pump 19 is pumped into pipe-line mixer 11.When sodium hydroxide chemicals dosing plant 13 or 14 liquid level of sodium hypochlorite medicine adding device are lower, meter
Amount pump 19 stops working.
Alkalinity sterilizes restorative cleaning step are as follows: and it carries out gas and cleans step, after and then opening backwash valve 9 and upper valve 4,
Backwashing pump 15 is opened again, and backwashing pump 15 directly draws water from water producing tank 16, opens simultaneously sodium hydroxide chemicals dosing plant 13 and time chlorine
Sour sodium chemicals dosing plant 14 squeezes into entire ultra-filtration membrane device 6 after pipe-line mixer 11, and the duration is about 60s, works as PH
After=11, backwash valve 9, upper valve 4, sodium hydroxide chemicals dosing plant 13 and sodium hypochlorite medicine adding device 14, backwashing pump are simultaneously closed off
15, and 15min is impregnated, a backwash step is entered after immersion, restarts normally water processed after backwash.
It should be noted that in the present invention unless specifically defined or limited otherwise, fisrt feature is in the second spy
It can be that the first and second features directly contact or the first and second features are connect indirectly by intermediary "above" or "below" sign
Touching.Moreover, fisrt feature can be above the second feature " above ", " above " and " above " fisrt feature right above second feature or
Oblique upper, or first feature horizontal height is merely representative of higher than second feature.Fisrt feature second feature " under ", " lower section "
" following " can be fisrt feature and be directly under or diagonally below the second feature, or is merely representative of first feature horizontal height and is less than
