Particularly, the method is characterized by comprising the following steps of: sucking the water in the natural water systems and the manmade water systems, then performing a primary solid-liquid separating process to the algae contained in the raw water, supplying the discharged water after the primary solid-liquid separating process to a filter device to perform a secondary solid-liquid separating process to separate the algae remained in the discharged water, then feeding the chlorine dioxide into the discharged water through the filter device, thereby preventing generating biomembrane and removing the biomembrane in the filter device so as to improve the filter efficiency, finally, feeding the chlorine dioxide into the discharged water of the filter device to remove the residual algae discharged in the discharged water of the natural water system and manmade water system to improve the concentration of the dissolved oxygen.
Description
Technical field
The present invention relates to a kind of method and device thereof that utilizes dioxide peroxide to remove algae, it is used for removing the algae of artificial water systems such as natural stream networks such as reservoir, lake, rivers and golf course, and this algae can sharply breed and cause easily red algae and green alga phenomenon in above-mentioned water system.
Background technology
Generally, when if nutrient salts content such as the organism in the artificial water system such as natural stream networks such as reservoir, lake, rivers and golf course, nitrogen, phosphorus too much the eutrophication phenomenon occurs, the vegetalitas planktonic organism or the algae that absorb this nutritive substance will sharply breed at short notice, thereby whole water system is dyed redness or yellow-green colour, cause red algae or green alga phenomenon thus.
When nitrogen (N), the phosphorus required nutritive ingredient materials of algae reproduction such as (P) above-mentioned eutrophication phenomenon can occur when putting aside too much in lakes and marhshes (lake, reservoir).Promptly, nutrient salts content can be suitably through processes such as dilution, precipitation, biological decomposition and obtain natural purification, if but disposablely supply nutrient salts too much and when making lakes and marhshes lose self-purification capacity, a large amount of breedings of various algae will be occurred, and the vicious cycle that the algae resolvent becomes the nutritive substance of other algae once more can be repeated.
Be in the red algae or the green alga phenomenon that occur in the lakes and marhshes of eutrophication state the color of water system water body is changed, can significantly reduce water transparency simultaneously and endanger surrounding landscape, the oxygen that also can make water system inside is exhausted and cause hydrobiont death.The remains of the breeding algae that is killed can rot gradually after sinking to the bottom and produce toxic substance and the smell that gives out a foul smell, thereby cause water quality deterioration.When if the green alga phenomenon appears in the water source especially from the beginning, not only have peculiar smell in intractable but also the treated tap water.
The method of removing red algae and green alga has multiple, such as comprising following method: loess is shed method, Xiang Shuizhong sheds loess, and the adsorption and the force of flocculation that utilize loess to have come the nutrient salts in the planar water to reach the sharply algae of breeding, carry out flocculation treatment afterwards again; The flocculation agent throw-in play, Xiang Shuizhong drops into flocculation agent and reaches the algae of sharply breeding and carry out flocculation treatment in order to the cohesion nutrient salts; Utilize the waterplant method, planting aquatic plants in water absorbs nutrient salts to reach the purpose of removing it by its root; The dissolved air floating method, Xiang Shuizhong feeds high-pressure air so that the dissolved air in the water produces floatingly, meanwhile, drives nutrient salts and algae and makes it floating, and then reach the purpose of removing them; Utilize the method for ozone killing microorganisms; The bubble that utilizes electrolytic reaction to produce carries out isolating floating partition method to it; The chlorine that is produced when feeding electrolytic seawater is removed the method for algae etc.
But above-mentioned loess is shed the emergency schedule that method just can be handled rapidly at short notice, after after a while, because of planktonic organism and turbidity can increase gradually, so still can make water quality deterioration.When adopting above-mentioned flocculation agent throw-in play, not only can spend great number flocculation agent expense, and also might produce 2 pollutions behind water pollutant and the flocculation agent generation chemical reaction because of buying flocculation agent.Though the processing costs when employing utilizes the waterplant method is lower, but because waterplant is comparatively responsive to season and outside temperature condition, be restricted so not only use, and because waterplant residue after death itself also is an organism, so it also can become water pollution source.When adopting the dissolved air floating method, owing to only depending on the dissolved air particulate to be difficult to make in the water breeding algae floating, so this method not only is difficult to improve elimination efficiency, but also need be from the outside high-pressure air that feeds of water system, thereby can need great number equipment cost and associated maintenance expense, the scene is killed and the badly damaged surrounding landscape of buoyant planktonic organism meeting.The ozonize method is to feed the method that ozone is sterilized by ozonizer in water, but ozonizer itself belongs to the high price equipment, and it also has certain danger and can send the peculiar stench of ozone.The trickle bubble that utilizes the floating law of segregation of electrolytic reaction to utilize in the electrolytic process to be produced makes on algae climbs up on top of the water, but the energy consumption height of large-scale electrolysis device, has a big risk.The method of the chlorine that is produced when feeding electrolytic seawater can only be in marine use, and because this method directly feeds the chlorine that electrolytic reaction produced in seawater, so its economy is lower.
As mentioned above, up to the present, method of the removing algae that people propose and device respectively have relative merits, so people are difficult to only use some methods wherein.For example, when adopting the method for removing algae such as directly in lakes and marhshes, shedding loess, flocculation agent or sterilizing agent and nutrient salts, can not be lasting though effect is fast, because the algae that has been killed also can produce large amount of organic after decomposing, so red algae, green alga etc. also can occur and form serious vicious cycle again.
Yet, adopt and in other treatment unit that other establishes, to remove algae and nutrient salts after the suction lakes and marhshes water and again when lakes and marhshes are released the method for water, remove algae owing to utilize centrifugation, floating separation, microstrain solid-liquid isolation methods such as (microstraining), so when adopting this method, though can from the water system water body, isolate algae fully, but it not only needs the high price equipment, and the consumption of the energy and various running stores is also more.
In addition, when utilizing ultraviolet ray, ozone or chlorine etc. to kill algae, though this method can be removed red algae and green alga rapidly, when carrying out disinfection too much, the toxicity of sterilizing agent can produce baneful influence to other waterplant.Otherwise, when utilizing microorganism or aquatic plant purification water quality, though this method at the root material of removing red algae and green alga, be to have advantage aspect the nutrient salts, but because this method is being difficult to implement in the water system on a large scale, so its not only produce little effect and also removing speed slow, so this method can only be used as ancillary technique and use.
At this point, recently people develop some and utilize chemical and physical properties to carry out method that solid-liquid separation handles and the method for utilizing ultraviolet ray, ozone or chlorine etc. together to handle.Someone has proposed for example to utilize flocculation-buoyant solid-liquid isolation method to remove after the algae, feeds the method for chlorine in the water of releasing.But chlorine can be with organism generation chemical reaction in the water system water body and is generated carcinogenic substance.Otherwise though the carcinogenic substance growing amount when utilizing ultraviolet ray or ozone to handle is few, the removing effect of the water of releasing is not lasting.Therefore if the time of contact ultraviolet ray or ozone is inadequate, the algae or the spore that are contained in the water of releasing also can be bred once more.
In addition, as the algae in the lakes and marhshes being carried out the method that solid-liquid separation is handled, the someone has proposed flocculation-filter method.In it filters operation, can remove comparatively trickle throw out according to the strainer space, this filtrations operation seems of great use, but when real processing contained the former water of algae in the reality, there was the relatively poor problem of filtration efficiency in this method.
That is, Fig. 4 represents to adopt the removing algae device that utilizes flocculation-filter method in the prior art.As shown in the figure, removing algae device of the prior art comprises: artificial floating bed 150, and it is installed in the bottom of the device that buoyancy is provided, and is in levitated state to keep this device; Flocculation agent storage tank 121, it is installed in the top of artificial floating bed 150, and the flocculation agent of storage inside is used to condense pollutent; Flocculation agent transferpump 122 is exported flocculation agent by it from the flocculation agent storage tank; Former water working shaft 110, its with run through the pipe connection of artificial floating bed 150 and be used for introducing former water; T-valve 160, it is installed on the connecting portion of former water working shaft 110 export pipelines and flocculation agent transferpump 122 export pipelines, the pollutent in the former water that precipitates with discharge; Strainer 130, it filters and discharges the not deposit fouling thing by T-valve.
But the filtration operation that adopts the removing algae device that utilizes flocculation-filter method in the prior art easily forms microbial film (biofilm) in its strainer 130 after operation for some time.If in strainer 130, form microbial film, space that will blocking filter and reduce filtration efficiency.Therefore the top of strainer 130 is equipped with tensimeter 131 in the prior art, in case the force value that shows just shunt when exceeding the filter criteria force value in its pipeline mid-way, even with the flow through amount of former water of strainer 130 of assurance.Because of the strainer 130 of can not flowed through by the pollutent (flocculation agent) shunted directly is discharged in the water system, so can reduce the algae elimination efficiency.Otherwise,, then need manually to change at set intervals No. one time strainer 130 if improve the algae elimination efficiency.Because the microbial film that forms not only can shorten the life-span of strainer 130, therefore this method also can utilize the removing algae device of flocculation-filter method to be difficult to realize practicability because of the frequent strainer 130 of changing goes up by expense.

Embodiment
Describing the present invention with reference to the accompanying drawings in detail utilizes dioxide peroxide to remove the method for algae and the embodiment of device thereof.
At first, Fig. 1 is that expression explanation the present invention utilizes dioxide peroxide to remove method and the schematic representation of apparatus thereof of algae.
As shown in the figure, removing method of the present invention is ' the outer treatment process of water system ', that is, and and the water body in the suction water system, the water of after removing algae device removing algae and nutrient salts, in water system, releasing again.Its characteristics are to feed dioxide peroxide in order to kill contained algae in the former water in the former water of inflow filter, this method can suppress to form microbial film and remove microbial film and improve filtration efficiency, feeds dioxide peroxide again and prevent that to remove residual algae it from breeding once more and improve dissolved oxygen concentration in the water of releasing of filtration unit discharging.
Promptly, with the water body in the artificial water systems such as natural stream networks such as suction pump 10 suction reservoirs, lake, rivers and golf course to removing in the algae device 20, in removing algae device 20, algae and the water of releasing are carried out solid-liquid separation and handle, can be discharged into the water system once more from removing the water of releasing that algae device 20 discharges through flocculation, processings such as floating.Then handle from removing algae device 20 isolated mud by sludge treatment equipment.
At this moment, the front end feeding of filtration operation in order to kill the algae that contains in the former water, suppresses formation microbial film and removing microbial film by the dioxide peroxide of chlorine dioxide generator 30 generations in filtering operation in removing algae device 20.And in the water of releasing that is discharged to water system, feed the dioxide peroxide that generates by chlorine dioxide generator 30 too, in order to the removing residual algae in the water of releasing.
Therefore compared with prior art, the present invention utilizes method and the device thereof of dioxide peroxide removing algae not only can improve the algae elimination efficiency, reduce maintenance cost, can also reduce the influence to aquatic environment to greatest extent.
Removing algae method of the present invention is: pumping unit lakes and marhshes water and remove algae after, be discharged in the lakes and marhshes after in the water of releasing that algae has been eliminated, feeding dioxide peroxide again.This point differs from ' treatment process in the water system ' that directly feeds dioxide peroxide in the water system water body.That is to say, when adopting ' treatment process in the water system ' of prior art,, need in water body, directly feed a large amount of dioxide peroxide for removing the algae in the lakes and marhshes.But owing to be difficult to keep the concentration of dioxide peroxide to be in proper state when adopting in this water system treatment process, so it is lower that this method is not only removed algae efficient, and, can produce foul odour on the contrary or have influence on hydrobiont when if the too high situation of chlorine dioxide concentration occurring.Also have, the algae that is killed can only sink to the bottom and can not remove nutrient salts as red algae or green alga root material.
Yet, when adopting ' treatment process outside the water system ' of the present invention, after the water body of suction in the water system is to the removing algae device of the present invention, by flocculation, floating or filter or the like and to handle and the algae that contains in the former water and nutrient salts are carried out that solid-liquid separation is handled and with its removing, feed dioxide peroxide and further kill the algae or the spore of failing to remove in the solid-liquid separation processing in the water of releasing, the present invention can improve the elimination efficiency of red algae and green alga greatly.And compared with prior art, in the water of removing after solid-liquid separation of the present invention is handled of releasing, can significantly reduce the usage quantity of dioxide peroxide during residual algae, but also can keep dioxide peroxide to have suitable concentration, thereby can not produce foul odour or have influence on aquatic environment, make cake to handling after the compressed again and dehydration procedure of separated algae and handle, so just can from water system, dispose pollutent fully through solid-liquid separation.
Fig. 2 is that expression the present invention utilizes dioxide peroxide to remove the schema of 1 embodiment of the method for algae.
The present invention includes: suction contains the former water sucting stage S100 of the former water of algae from water system; In the former water that sucks, drop into flocculation agent and form the flocculation stage S200 of the throw out that contains algae; Utilizing bubble that the throw out that forms in the flocculation stage is climbed up on top of the water goes up and carries out isolating floating separation phase S300; The 1st dioxide peroxide that feeds dioxide peroxide in the water of releasing that floating separation phase is discharged drops into stage S400; The water of releasing that has comprised dioxide peroxide in the 1st dioxide peroxide input stage is carried out solid-liquid separation to be handled and filtering filtration stage S500; The 2nd dioxide peroxide that feeds dioxide peroxide in filtration stage in the water of releasing that discharges drops into stage S600; The water of releasing that has comprised dioxide peroxide in the 2nd dioxide peroxide input stage is discharged to the water discharge phase S700 that releases in the water system; Compress the mud compression stage S800 of sludge discharged in floating separation phase and the filtration stage; Extruding has been compressed mud and has been made the water smoking S900 of sludge cake; The water of releasing that makes the mud compression stage and discharge in the water smoking is back to the water refluxing stage S1000 that releases in flocculation stage again.In addition, the present invention also comprises the on-the-spot dioxide peroxide supply stage S1100 that the 1st and the 2nd dioxide peroxide drops into required dioxide peroxide of stage that makes.
Former water sucting stage S100 among the present invention is meant after the water body of artificial water systems such as natural stream networks such as suction reservoir, lake, rivers and golf course, the more former water that contains algae introduced the present invention and removes stage in the algae device 20.
At this moment, removing of the present invention algae device 20 is installed near the of lake, reservoir nearby or swims on the water surface of lake, reservoir and get final product.Former water sucks by flexible pipe and removes in the algae device 20.
Flocculation stage S200 be meant in containing the former water of algae drop into flocculation agent and in and the electric charge of algae microparticle surfaces, perhaps become big flocculation process at the particle coagulation that makes of colloid surface by absorption and bridging effect, can form the throw out that contains algae at last.Employed flocculation agent of flocculation stage can use employed molysite or aluminium salt in the water treatment procedure.
Floating separation phase S300 is meant the former water that is formed with throw out is introduced in the floating matter separator tank 222, provide the trickle bubble that produces by aerator 226 to the bottom of floating matter separator tank 222, the throw out that flocculated and trickle bubble are collided and adhere to generation throw out-bubble incorporation body and stage on climbing up on top of the water.Meanwhile, obtain the floating matter on the water surface that floats to floating matter separator tank 222 with floating matter clearing device 227 and it is discharged to the outside, the water of releasing is by the water pipe discharging of releasing.In addition, also can utilize the high pressure water that high-pressure water pipe ejects to produce trickle bubble.
Filtration stage S500 is meant by being filled in the filtrates such as filter material layer, micro-strainer or strainer (or claiming strainer) in the filter vat 241, the stage of removing the trickle throw out that is contained in the water of releasing of floating separation phase S300 discharging once more.Meanwhile, the water of releasing that flows through filtrate is discharged by handling pipe.So, the filtrate that is formed with trickle through hole owing to the filtration stage utilization carries out the solid-liquid separation processing, so blocked through filtrate through hole meeting afterwards after a while, frequent if desired replacing or cleaning filtrate then can reduce filtration efficiency.Therefore, just should not make the filtrate through hole blocked in order to improve filtration efficiency.
But, owing to contain the more algae that is not eliminated in the water of releasing of floating separation phase S300 discharging, so in filtrate, be easy to form microbial film (biofilm).Microbial film is meant because of the growth of tiny microflora and is formed on the material with 3 dimension structures on the filter material surface, its material with comparatively robust structure for being made up of microorganism and secreted EPM (extracellular polymeric matrix) thereof.Difference according to microbe species, above-mentioned biomembranous thickness maximum can reach 100 μ m, is difficult for disintegrating or separating because its physical properties shows as, therefore, after on filter material surface, forming microbial film, can hinder moving of throw out, thereby can reduce filtration efficiency.Microbial film not only can shorten the life-span of filtrate, and this method also can be because of the frequent filtrate of changing goes up by expense, and it is difficult to be provided with the major cause of filtering operation for method and the device thereof of removing algae in the prior art.
For solving the problems of the technologies described above, in removing algae method of the present invention, in the water of releasing that flows into filtration stage, feed dioxide peroxide, form microbial film on the filtrate or remove established microbial film in order to be suppressed at.
The fusing point of dioxide peroxide (chlorine dioxide) is that-59 ℃, boiling point are 11 ℃, and under normal temperature environment, it is the yellow-green colour gas of slightly chlorine smell, and soluble in water and ether etc. have stronger oxidation capacity and have sterilizing function.It is reported that reducing aspect bacterium, virus active, dioxide peroxide has the effect not worse than chlorine.Dioxide peroxide is easily absorbed by peptone (a kind of protein), and virus is wrapped in the albuminous membranae usually, in case when this film absorbs dioxide peroxide, just can reduce viral activity.Especially dioxide peroxide is as the sterilization, the sterilizing agent that contain the aerobic base, and its oxidation capacity exceeds 2.5 times than original chloro.As removing virus and green algae, the most effective sterilization of spore class, sterilizing agent, dioxide peroxide can have the sterilization ability in big pH value scope (2～10).When being lower than 17ppm, the concentration of dioxide peroxide do not have the medicament smell, even can bring into play abundant sterilization, disinfection efficacy during its concentration lower (1ppm) yet.Be that the dioxide peroxide of 0.25ppm is killed the required deficiency of time of intestinal bacteria more than 99% 41 seconds for example with concentration.
Therefore drop into stage S400 at the 1st dioxide peroxide and in the water of releasing of floating separation phase discharging, feed dioxide peroxide, and the concentration of dioxide peroxide remains between 0.1～1ppm in the water of will releasing, and can suppress thus to form microbial film in the filtration stage or remove established microbial film and improve filtration efficiency on filter material surface.
Drop into stage S600 at the 2nd dioxide peroxide and in filtration stage is discharged into the water of releasing in the water system, feed dioxide peroxide, and the concentration of dioxide peroxide remains between 0.1～1ppm in the water of will releasing, and can kill the algae and the spore that remain in the water of releasing thus.The oxygen that is produced when being decomposed by dioxide peroxide in addition, improves the dissolved oxygen concentration of the water of releasing.
That is, dioxide peroxide is not formed non-toxic substance owing to it can not produce carcinogenic substance and be easy to by light, so can endanger environment hardly as containing the sterilization of aerobic base, sterilizing agent quick the decomposition.Meanwhile, because dioxide peroxide is the oxygenant that contains the aerobic base, thus can in decomposition course, produce oxygen, thus can improve water quality by increasing dissolved oxygen (DO).Chlorite (chlorite) that is generated by dioxide peroxide and oxymuriate (chlorate) are that numerous inorganicss and hydrobiont produce the final product of reaction back generation in the water, and it can prevent that bacterium from breeding once more.
Dioxide peroxide is at present also not quite clear as the concrete influence to environment after the sterilant use, it is reported that its influence is littler than the influence of chlorine at least.The dioxide peroxide and the chlorite maximum contaminant level of U.S.'s regulation respectively are 0.8ppm and 1.0ppm.
Therefore, dropping into stage S600 at the 2nd dioxide peroxide is discharged to it in water system after the feeding dioxide peroxide in the water of releasing of filtration stage discharging, perhaps make the water of releasing that is stored in the tank of releasing keep the sterilization ability and kill algae and spore with this, just can prevent that it from breeding once more, can improve dissolved oxygen concentration simultaneously and improve water quality.
In addition, dioxide peroxide is active higher molecularity free radical morphologization compound, and high concentration of chlorine dioxide gas re-uses hardly, mainly produces the dioxide peroxide of aqueous solution state.The compressible at normal temperatures one-tenth liquid state of chlorine dioxide, but the pure chlorine dioxide liquid property after being compressed is very unstable, the dangerous of the blast of producing is arranged and be difficult to keeping and transportation, needs to make at the scene.Its manufacture method has three kinds usually, wherein makes Textone (NaClO
2) and chlorine generation chemical reaction and the method that generates gaseous chlorine dioxide have the yield rate height, generate the advantage of byproduct hardly, chemical equation is as follows:
2NaClO
2+Cl
2→2ClO
2+2NaCl
When calculating, can generate the 1.0mg dioxide peroxide behind 1.34mg Textone and the 0.5mg chlorine generation chemical reaction according to following formula.But, be 1.68mg so produce the needed common Textone of 1.0mg dioxide peroxide because the Textone purity in the reality is about 80%.
That is, dioxide peroxide supply stage S1100 is meant and makes at the scene the stage that supply the 1st and the 2nd dioxide peroxide drops into the required dioxide peroxide of stage S400, S600.Preferably the raw material sodium chlorite aqueous solution is carried out electrolysis treatment and makes aqueous solution of chlorine dioxide, again this aqueous solution of chlorine dioxide is conducted to the 1st and the 2nd dioxide peroxide and drops into stage S400, S600 at dioxide peroxide supply stage S1100.
In addition, mud compression stage S800 is meant the stage that mud that floating separation phase S300 and filtration stage S500 are produced precipitates, compress, and water smoking S900 is meant that the mud that will compress carries out the pressurizing and dehydrating processing and stage of making sludge cake.
In addition, the water discharge phase of releasing S700 is meant that the water of releasing that the 2nd dioxide peroxide stage of dropping into has been comprised dioxide peroxide is discharged to the stage in the water system again, and the water refluxing stage stage S1000 that releases is the stage of instigating the water of releasing of mud compression stage and water smoking discharging to be back to the flocculation stage again and to handle.
