Purifier is used to purify the water that above-mentioned water supply installation is discharged, and discharges purification back water.
Wherein, default low flow velocity can be according to purifier and user's requirements set.
When water supply installation drains into purifier by preset flow rate with water to be clean, at first, preset flow rate should guarantee that the speed of the water to be clean that water supply installation provides is not more than purifier and discharges the Peak Flow Rate that purifies back water, and work as purifier as shown in Figure 4, when the first filter material layer surface had formed the microorganism mucous membrane, preset flow rate also will satisfy the requirement of not disturbance filter material layer; Secondly, preset flow rate can also be set according to customer need, such as when user's water consumption hour, preset flow rate can be turned down, like this, when satisfying the demand of water user's water quality, the water yield, prolonged the life cycle of filtrate in the lauter tub.
In the water treating equipment that the embodiment of the invention provides, water supply installation offers purifier by preset flow rate with water to be clean, compared with prior art, described water supply installation has overcome existing water purifying plant and has caused the water inlet flow velocity of water purifying plant excessive or supply water by water tank median water level difference and to produce the hydraulic load problem of unstable easily by the direct water supply of water pump, the water inlet flow velocity of the purifier among the present invention not only can be controlled as required, but also more stable, can guarantee that the water quality that purifies back water does not exceed standard.
As shown in Figure 2, above-mentioned water supply installation can comprise:
Elevated tank is used to store water, and drainage water;
Galvanostat is used for the drainage speed of elevated tank is controlled at preset flow rate.
Preferably, as shown in Figure 2, the bottom of elevated tank also is provided with mud discharging mouth, is used to discharge the dirt such as particulate matter, earth of elevated tank bottom deposit.It is tapered that elevated tank can be rounding, so that suspended substance sedimentation such as particulate matter, earth is easy to collect and discharge by mud discharging mouth in the bottom in the elevated tank.Can also be communicated with a transparent pipe on the elevated tank, be used to do the water level indicating meter, and when elevated tank adopted transparent material to be made, the water level indicating meter can omit.
Above-mentioned water treating equipment also can comprise:
Strainer is used to filter the water that enters water supply installation, is provided with filtering net in the strainer, is used for tackling the suspended matter (Fig. 2 is the position that example shows strainer with the water supply installation that comprises elevated tank and galvanostat) of water.
The effect of strainer is that the macrobead pollutent in the water to be clean is tentatively tackled.Strainer comprises water-in, water outlet and the filtering net between water-in and water outlet, and filtering net can take out after obstruction with brush and clean, and reusable, if filtering net has broken down, the filtering net that can also more renew uses more convenient.After of the power process preliminary filtration of strainer of the effusive water of pump, enter water supply installation, alleviated the filtration burden of follow-up purifier, reduced the obstruction of filtrate in the purifier by pump.
Preferably, as shown in Figure 3, above-mentioned galvanostat can comprise:
Container places elevated tank, open top, and the bottom is interspersed with first pipe and second pipe;
First pipe is when being used for the water surface when elevated tank and being higher than the water surface in the container, in the importing of the water in elevated tank container;
Second pipe is communicated with the water outlet of elevated tank, is used for above-mentioned preset flow rate the water of container being directed at the water outlet of elevated tank.
The principle of work of above-mentioned galvanostat is that to utilize the inside and outside waterhead of container (be the waterhead of container and elevated tank, the water level of elevated tank will be higher than the water level in the container), keep waterhead constant, the draining constant flow rate of the then water inlet constant flow rate of first pipe, and then second pipe.Waterhead by inside and outside the adjustment container can reach the purpose that the drainage speed of elevated tank is controlled at preset flow rate.Adjusting the inside and outside waterhead of container can realize in the following manner: place some weights (as stone etc.) in container, when the drainage speed that requires elevated tank big (less), can place many in container (lacking) some weights, make waterhead increase (reducing), so that the drainage speed of elevated tank reaches requirement.In addition, in container, place under the certain condition of weight,, also can realize the adjusting that the container drainage speed reduces or increases by raising or lowering the height of first pipe in container.The introducing of galvanostat has overcome existing water treating equipment and has caused flow velocity excessive by direct water supply of water pump, and perhaps water supply produces problems such as hydraulic load shakiness by elevated tank median water level difference, has realized water supply low speed, constant function.
Again as shown in Figure 2, above-mentioned water treating equipment also can comprise:
Pump is used for the water at water source is directed in the elevated tank;
Switch box is used for opening or close pump according to the instruction of user's input;
Water level measurement device is used for measuring the water level of elevated tank, sends out code when water level reaches first preset value, sends enabled instruction when water level reaches second preset value, and first preset value is greater than second preset value;
Switch box also is used to receive enabled instruction or out code, and closes pump when receiving out code, opens pump when receiving enabled instruction.
Particularly, configurable driving switch on the switch box, the Far Left gear of driving switch are automatically, promptly above-mentioned water level measurement device and switch box cooperating, make and when the water level in the elevated tank reaches first preset value, close pump, when the water level in the elevated tank reaches second preset value, open pump; The middle gear of driving switch is for stopping, and promptly the user can close pump by gear in the middle of driving switch is screwed to; The rightmost gear of driving switch is manual, be that the user can come the enforced opening pump by driving switch being screwed to the rightmost gear, as need wash clothes, feed big yield such as livestock when family the time, the user can be at the direct water receiving in the water outlet place of elevated tank, need not be through the processing of purifier.In addition, run indicator can also be set on the switch box and stop pilot lamp, make the user clearly understand the working order of water treating equipment.
Water level measurement device can be embodied as electric fluviograph, and at this moment, switch box can be told a light current and press the survey water level gauge that is used for powering to use.Electric fluviograph can comprise the probe of two different lengthss, and long probe is nearer apart from elevated tank bottom, and when water level was reduced to long probe terminal, switch box was opened pump; Short probe is nearer apart from the elevated tank top, and when water level was raised to short probe terminal, switch box was closed pump, thereby realizes water inlet automatically.Electric fluviograph can adopt float switch or mechanical structure.
As shown in Figure 4, above-mentioned purifier can be biology and filters purifier slowly, and this biology is filtered purifier slowly and can be comprised:
Lauter tub has water-in and water outlet, and the water-in of lauter tub is communicated with the water outlet of water supply installation;
At least one metafiltration bed of material is arranged in lauter tub;
Microorganism mucous membrane attached to top layer filter material layer upper surface;
Wherein, the water-in of lauter tub is positioned at the top of microorganism mucous membrane, the below that water outlet is positioned at filter material layer.
The shape of above-mentioned lauter tub is not limit, and is generally right cylinder or rectangular parallelepiped, and for guaranteeing the even of current, the top cross-sectional area of lauter tub is a bit larger tham the bottom; The water-in of lauter tub is positioned at the upper end of lauter tub, and the water outlet of lauter tub is positioned at the lower end of lauter tub; In scavenging process, the water that water supply installation is discharged enters lauter tub by the water-in of lauter tub, through the biochemical action of filter material surface microorganism mucous membrane, and after the physical adsorption of the filter material layer filtration, discharges from the water outlet of lauter tub.
In addition, as shown in Figure 4, water outlet can cause about the 15cm of filtrate top water outlet and flow out by being connected with the elbow and the straight tube of lauter tub outside, guarantees the upper strata depth of water of filtrate top, guarantees to form the survival of microorganism mucous membrane and microorganism.Wherein, on straight tube that is connected with the water outlet of lauter tub and the elbow water flow control valve door can be set.
Under the slower situation of the flow velocity of the current that enter lauter tub, organism in the water and mineral substance can provide nutrition for the microbial growth breeding, therefore, there has been a large amount of micropopulations on the surface of filter material layer, micropopulation is attached to growing on the filter material layer surface, after growth after a while, can form and stablize sophisticated microorganism mucous membrane.Exist a large amount of biological groups such as algae, bacterium in the microorganism mucous membrane, also has protozoon in the upper water of filtrate top in addition, protozoon, algae can effectively engulf bacterium in the water, virus etc., and microorganisms such as bacterium can utilize the organism in self metabolic process degradation water, can also remove ammonia nitrogen in the water by nitration reaction, microorganism mucous membrane space is little, and the suspended impurity in all right trap water plays effective sterilization and filtering effect to water to be clean.
Through the water after the biochemical treatment of microorganism mucous membrane, can filter through the further physical adsorption of filter material layer, with the turbidity of further reduction water, improve decontamination effect improving.
Slowly filter purifier by above-mentioned biology, do not need to be provided with special disinfection apparatus, do not need to add any medicament yet, only adopt microorganism mucous membrane attached to top layer filter material layer upper surface, water to be clean is carried out disinfection and biochemical reaction, reduced sterilizing part, provided cost savings, easily accepted by the peasant; Simultaneously, by the physical adsorption of filter material layer, further water to be clean is filtered, in addition, above-mentioned biology filters slowly that purifier is simple in structure, the installation and operation cost is low, is highly suitable for the purification of rural potable water and domestic water.
Be understandable that, the thickness that above-mentioned biology is filtered the filter material layer that is provided with in the purifier slowly is big more, the type of filtrate many more (as adopting different particle diameter of filter medium collocation, different strainability filtrate collocation such as coconut husk, gac), the decontamination effect improving that biology is filtered purifier slowly is good more.Certainly, in order to save biological cost and the biological filtering velocity of filtering purifier slowly of assurance of filtering purifier slowly, need to select rational filter material layer thickness and filtrate type.
Generally, the filtrate in the top layer filter material layer is the thinner filtrate of particle diameter, and the particle diameter of filtrate is thin more, and its detergent power is strong more, therefore can effectively guarantee to purify the cleanliness factor of back water, and in addition, the particle diameter of filtrate is thin more, the also easy more formation of microorganism mucous membrane; Certainly, also cannot adopt the meticulous filtrate of particle diameter, in order to avoid water is difficult to maybe can't pass through; Consider biological perviousness of filtering purifier slowly, along water mobile direction, the particle diameter of the filtrate in the different filter material layers can be according to arranging from fine to coarse.Slowly filter purifier such as biology and comprise the four metafiltration bed of materials, the filtrate of supposing the top layer filter material layer is the thinner river sand of particle diameter, can certainly adopt quartz sand etc., because river sand is comparatively common in the rural area, draw materials convenient and cost low, therefore, generally, adopt the filtrate of river sand as the top layer filter material layer; The filtrate of second layer filter material layer is a zeolite; The filtrate of three-layer filter layer also is a zeolite, but the particle diameter of the zeolite in the three-layer filter layer is greater than the particle diameter of the zeolite in the second layer filter material layer; The 4th metafiltration bed of material can be the thicker river sand of particle diameter.Certainly, above-mentioned filter material layer can also be three layers, five layers or other number of plies, the filtrate in the filter material layer can also be other dissimilar filtrate, for example quartz sand, gac etc., in the specific implementation process, can be according to the filtrate resource situation of locality, the scheme that alternative costs are lower is implemented.
Slowly filter purifier by the biology that the foregoing description provides, can adopt the filter material layer of multilayer or dissimilar filtrates, strengthen physical adsorption filteration water to be clean.
In the foregoing description, when water to be clean enters lauter tub, if current are inhomogeneous or current are excessive, then may the disturbance filter material layer, thus be unfavorable for the formation of microorganism mucous membrane, simultaneously after the microorganism mucous membrane forms, integrity that also may the destroy microorganisms mucous membrane, for fear of this phenomenon occurring, as shown in Figure 5, above-mentioned biology is filtered purifier slowly and also can be comprised:
Water distributor between the water-in and filter material layer of lauter tub, is used for water distribution uniformity.The water to be clean that enters from the water-in of lauter tub can effectively reduce the flow velocity of water through behind the water distributor, and avoid the water impact of current his-and-hers watches metafiltration material, thereby help the formation of microorganism mucous membrane, and the integrity that keeps the microorganism mucous membrane.
Water distributor can adopt structures such as square basin, circular basin, bottom uniform distribution water distributing pore according to the structure of lauter tub.In order to increase the water distribution effect of water distributor, and further improve the removal effect of suspended substance in the water, reduce biological obstruction of filtering filtrate in the purifier slowly, can also lay filtrates such as coarse particles quartz sand, stone in the water distributor, and/or lay layer of non-woven fabric.When water distributor is crossed the reduction of water effect, can be reentered into after the taking-up of the filtrate in the water distributor flushing, recycling, easy to use.Non-woven fabrics can directly abandon because price is very cheap, more renews.
In addition, when the particle diameter of the filtrate in the lowest layer filter material layer was thin, the filtrate in the lowest layer filter material layer might stop up the water outlet of lauter tub, at this moment, can filter slowly at biology and following supporting layer was set in the purifier or porous plate prevents that the water outlet of lauter tub is blocked:
1, supporting layer
Again as shown in Figure 5, above-mentioned biology is filtered purifier slowly and also can be comprised:
Supporting layer is used for preventing that the filtrate of filter material layer from stopping up the water outlet of lauter tub, is arranged at the below of filter material layer, and the water outlet of lauter tub is arranged in supporting layer.
Supporting layer can effectively be collected draining, prevents that the filtrate in the filter material layer from stopping up and loss, and generally, supporting layer is made up of the thicker gravel of particle diameter.Certainly, also can adopt other method to prevent that the filtrate in the filter material layer from stopping up the water outlet of lauter tub, for example, one filter screen is set in the water inlet of the rising pipe of lauter tub.
2, porous plate
As shown in Figure 6, above-mentioned biology is filtered purifier slowly and also can be comprised:
Porous plate, be used to carry filter material layer, make to form a water space between the bottom of filter material layer and lauter tub, make the water that passes filter material layer enter water space and prevent that the filtrate in the filter material layer from falling into water space, be arranged at the below of filter material layer, the water outlet of lauter tub is communicated with water space.
Porous plate is the platy structure with a plurality of holes, and the aperture is for can deciding according to the particle diameter of the filtrate in the lowest layer filter material layer, should be advisable with the filtrate that can tackle in the lowest layer filter material layer in the aperture of porous plate.Porous plate can guarantee that water circulates to the bottom, and prevents that the top filtrate is through entering lower space; When the top filtrate took out, porous plate can be taken out cleaning; The porous plate bottom is a water space, and the water of bottom flows out by the water outlet of lauter tub, can be collected into containers such as bucket, cylinder, basin from the effusive purification of the water outlet of lauter tub back water.
Porous plate is compared with supporting layer, its thickness is less, has correspondingly reduced the biological height of filtering purifier slowly, has dwindled the volume of water treating equipment.
In addition, in order to prevent the destruction of pollutents such as rain drop erosion or dust to microorganism mucous membrane and filter material layer, biology is filtered purifier slowly and also can be comprised: top cover is positioned at the top of lauter tub.Preferably, top cover is that transparent material is made, so that have enough light in the lauter tub, impels the formation and the growth of microorganism mucous membrane; Certainly,, also can not use top cover, so that have enough light and air, for the formation and the generation of microorganism mucous membrane provides good environment if when biology is filtered purifier slowly and is positioned at excellent environment such as indoor.
Be illustrated in figure 7 as the operating process synoptic diagram of above-mentioned water treating equipment, may further comprise the steps:
Step S71, preparation work.
Switch box is connected with power supply.
When purifier is that biology is when filtering purifier slowly (as Fig. 4,5 or 6), at first in lauter tub, add a certain amount of water, load filtrate then successively, and add water simultaneously, when loading filtrate, need extrude the bubble in the filter material layer, and guarantee that filtrate all contacts with water, prevent that current are short-circuited in the water purification process; After filtrate is loaded and to be finished, the filtrate of top layer filter material layer upper surface is touched flat, be beneficial to the formation of microorganism mucous membrane.
The water outlet of lauter tub is connected with the elbow and the straight tube of lauter tub outside, water outlet is caused apart from flowing out about the 15cm of filtrate top, guarantee the upper strata depth of water of filtrate top.
Step S72, utilize the switch box control pump to start working.
Switch box is provided with automatically, stops, manual three kinds of driving switch, and the user can make pump need come work by the user by stirring these driving switch.Such as, user expectation can continue to obtain to purify waste water, and then the user can push driving switch automatic gear; Purified waste water enough or need carry out clean and maintenance etc. to water treating equipment when what the user obtained, then the user can push driving switch the gear that stops; When big yields such as user expectation need be washed clothes, hello livestock, the user can push driving switch manual gear and come the enforced opening pump, and the user can need not pass through the processing of purifier at the direct water receiving in the water outlet place of elevated tank.
Step S73, pump extract water from the water source, water is entered in the elevated tank through after the preliminary filtration of strainer.
Water in step S74, the elevated tank drains in the purifier by preset flow rate under the control of galvanostat.
Wherein, when galvanostat is structure shown in Figure 3, can reach the purpose that the drainage speed of elevated tank is controlled at preset flow rate by the waterhead inside and outside the adjustment container.Adjusting the inside and outside waterhead of container can realize in the following manner: place some weights (as stone etc.) in container, when the drainage speed that requires elevated tank big (less), can place many in container (lacking) some weights, make waterhead increase (reducing), so that the drainage speed of elevated tank reaches requirement;
In addition, when the driving switch of switch box is screwed onto automatic gear, water level in the water level measurement device The real time measure elevated tank, when water level reaches first preset value, water level measurement device can send out code to switch box, switch box is closed pump according to out code, to stop to avoid the water in the elevated tank to overflow to the elevated tank water inlet; And when water level reaches second preset value, water level measurement device can send enabled instruction to switch box, switch box is according to the enabled instruction ejector priming, and restarting to the elevated tank water inlet, above automatic control process can guarantee that elevated tank is in normal operating conditions always.
Step S75, purifier carry out purifying treatment to water.
Particularly, as shown in Figure 8, when purifier is a biology when filtering purifier slowly, biologically filters purifier slowly the process that water purifies be may further comprise the steps:
The water that step S751, elevated tank are discharged enters lauter tub from the water-in on lauter tub top, and the water distributor that is arranged at the filter material layer top carries out water distribution uniformity to water.
Step S752, low filtering velocity (with respect to normal operation condition) operation.
Starting stage, adopt low filtering velocity water inlet (be galvanostat the drainage speed of elevated tank is controlled to be a lower flow velocity), in case the disturbance filter material layer, the low formation that also is beneficial to the microorganism mucous membrane of filtering velocity simultaneously; Whether continue low filtering velocity operation for some time, the water that the water outlet of lauter tub is discharged is chemically examined, it is working properly to detect filter material layer.
Step S753 progressively increases filtering velocity to preset value.
If filter material layer is working properly, the clearance that is pollutent remains unchanged substantially, the upper surface that shows filter material layer has formed mature and stable microorganism mucous membrane, can increase filtering traffic this moment up to preset value (be galvanostat the drainage speed of elevated tank is increased to preset value).
Step S754 filters and normally carries out.
Draining water quality keeps under the stable status, and the maintenance filtering velocity is preset value (is galvanostat the drainage speed of elevated tank is controlled at preset value), continuous service.
Step S755, filtrate stops up.
If the water displacement of lauter tub is more and more littler, illustrate that filtrate stops up, need to clean filtrate.
Step S756, the top layer filtrate is removed.
The user is out of service by the switch box control pump, treat that water in the lauter tub puts when exposing top layer filter material layer surperficial, remove with the top layer filtrate with attached to the microorganism mucous membrane on the top layer filter material surface at once, clean soon more, possibility that the filtrate in lower floor's filter material layer is disturbed and annoyance level are just more little.
In sum, the embodiment of the invention offers purifier by preset flow rate with water to be clean by water supply installation, and compared with prior art, the hydraulic load of purifier is stable in the embodiment of the invention, the phenomenon of the overproof water quality of water after avoiding occurring purifying.In addition, if being biology, purifier filters purifier slowly, the then biological purifier of filtering slowly adopts and is positioned at the microorganism mucous membrane of top layer filter material layer upper surface to water disinfection to be clean, do not need special disinfection apparatus, easy to operate, pollution substances such as bacterium, virus, organic pollutant there is good removal effect; In addition, adopt the multilayer filter material layer to carry out Filtration Adsorption, make final draining water quality satisfy state specified standards; In addition, it is simple in structure that biology is filtered purifier slowly, and the installation and operation cost is low, is applicable to the particular case in China rural area.
