Embodiment 2
Present embodiment has been introduced a kind of method of purifying waste water with the sewage purifier of embodiment 1, and its operating process is following:
Check earlier before the operation of
equipment whether each pipeline connects with each components and parts intact, if excellent, then equipment is launched in preparation.Former water gets into before the filter element, and is anhydrous in the filter core 3, therefore needs earlier water filling in the backwash water tank 8; Close the A point valve of triple valve 5, start first water pump 6 (being M1), make current in the backwash water tank 8 through the first backwash water pipe 9, triple valve 5, first water pump 6 and the second backwash water pipe 10; And then in first water producing pipe, 4 inflow filter cores 3; Water filling in filter core 3, the air in the filter core 3 upwards gets into evacuated tube 23, subsequently from the top of backwash water tank 8 and discharge.When this process was carried out, operating personnel can discharge situation through the air that the transparent tube on the evacuated tube 23 230 is observed in the evacuated tube 23.After the emptying operation is accomplished, valve-off K6, the equipment of launching as follows again produces water:
a, earlier former water is flowed in the water tank with strainer 1; Open first water pump 6 (being M1) then; Close the B point interface on the triple valve 5 simultaneously, open the A point and the C point interface of triple valve 5, make former water filter the output water purification through filter core 3; Said water purification flow through first water producing pipe 4, triple valve 5 and first water pump 6 flow out from second water producing pipe 7 at last; And a part of water purification in second water producing pipe 7 flows into the backwash water tank 8 from backwash tank inlet pipe 11; When the water purification in the backwash water tank 8 reached designated water level, first float switch 12 cut out automatically with control backwash tank inlet pipe 11 and no longer in backwash water tank 8, supplies water.
B, step a carry out setting-up time, promptly produce water after a period of time, and filter core has been held back some dirts outward; Untimely cleaning can influence the filter effect of filter core, and therefore must carry out following backwash step: autocontrol valve F7 closes, and controls the A point interface of triple valve 5 automatically and closes; Switching to B point and C point interface connects; First water pump 6 remains in operation, and stops to produce water then the water in the backwash water tank 8 is extracted out, and the current in the backwash water tank 8 are through the first backwash water pipe 9, triple valve 5, first water pump 6 and the second backwash water pipe 10; Get back to the filter core 3 from first water producing pipe 4 at last, and contrary filtering direction carries out backwash to the filter core 3 outer dirts of being held back;
Produce in the middle of the process of water and backwash
, because the pressure of pump can not be realized electrodeless adjusting, therefore can regulate the pressure when producing water and backwash through changing the size of the valve K9 on the pressure regulation tube 22.In the present embodiment, the time that forward produces water is 30s ~ 5min, produces water pressure and is controlled at≤0.05MPa; The time of backwash is about forward and produces 1/20 ~ 1/10 of the water time; Backwashing pressure should be controlled to be forward and produce about 2 times of water pressure, so is about 0.1MPa, thereby guarantees the efficient of backwash.In addition, if forward produces more than one of the filter element of water, can replace or by turns each filter element is carried out backwash operation.
C, repeating step a and b be for several times in order;
d, behind step c; Forward produces water to have carried out repeatedly with reverse backwash process; Dirt is accumulated in the bottom of water tank with strainer 1 gradually; Form denseer concentrated sewage; Therefore can carry out a circularly purifying operation to this part concentrated sewage: open sewage water inlet pipe 14, the partial concentration sewage of water tank with strainer 1 bottom is flowed in the sewage water tank 13, start second water pump 17 (being M3); Effluent stream in the sewage water tank 13 is got back to the water tank with strainer 1 from effluent cycle water pipe 16 through second water pump 17, filter 18 (refer to carry out sewage the existing filter of coarse filtration, can be cloth envelop collector or fabric filter etc.) and ultraviolet sterilization apparatus 19; After this process is carried out a period of time, close second water pump 17 and sewage water inlet pipe 14, promptly finish the effluent cycle purification process.
e, repeat above-mentioned steps a to d for several times in order, until arrestment running on demand.Other, the mud of the last deposition of device bottom etc. can be discharged through blow-off pipe 20.
Embodiment 1 is that a cover novel anti is stopped up the membrane filtration cleaning system with embodiment 2 described sewage purifiers, and integrated level is high, good filtration effect; Equipment produces water and does not contain microorganism, virus-free, the filter membrane flow＞300L/m of filter core
2
Hr, the 20L/m and the filter membrane flow of like product of the same trade is only had an appointment
2
Hr, the filter membrane flow of present embodiment sewage purifier are higher than about 15 times of like product; And water body purification capable of circulation can realize the zero-emission of sewage basically, and equipment investment cost is low.
this sewage purifier can be used for trade effluent processing, swimming pool or hot spring and does not have the purification of chlorination, hotel or office building sanitary sewage disposal, municipal sewage treatment, urban look water treatment and high aquaculture system and disinfects etc.
More than the utility model has been done detailed description; Its purpose is to let the personage that is familiar with this art can understand the content of the utility model and implements; Can not limit the protection domain of the utility model with this; All equivalences of doing according to the spirit of the utility model change or modify, and all should be encompassed in the protection domain of the utility model
