In the case that in raw water quality index, ammonia nitrogen is relatively low, biological filter unit can be surmounted, now, combination system System is changed into the combination of tube settling-Carbon-sand filter-ultrafiltration membrane treatment system;In the case where raw water organic matter is not high, can be to smelly Oxygen Carbon-sand filter unit is surmounted, and now, combined system is changed into the group of biofilter-tube settling-ultrafiltration membrane treatment system Close;When in raw water turbidity it is relatively low in the case of, ultrafiltration film unit can be surmounted, now, combined system be changed into biofilter- The combination of tube settling-Carbon-sand filter processing system.
The combined system that the utility model is provided is filtered and ultrafiltration membrane treatment with biofiltration, tube settling, ozone-charcoal sand Technology is core process, effectively plays synergy, substantially excellent with improving producing water water quality, saving land used and saving medicament etc. Gesture, is particularly well-suited to the process of the very intractable high NH4 source water of routine techniques.
Description of the drawings
Fig. 1 is a kind of structural representation of efficient combination processing system for high NH4 source water of the present utility model.
Specific embodiment
Below in conjunction with accompanying drawing, by specific embodiment, the utility model will be further described, and these embodiments are only used for The utility model is illustrated, is not the restriction to the utility model protection domain.
As shown in figure 1, a kind of efficient combination processing system for high NH4 source water provided for the utility model, its bag Contain:The biological filter unit 20 that is sequentially communicated, tube settling unit 30(It is preferred that folded plate type inclined tube), Carbon-sand filter 40, milipore filter Unit 50, wherein, described biological filter unit 20 is connected with raw water 10, described tube settling unit 30, Carbon-sand filter list Unit 40, ultrafiltration film unit 50 is by pipeline communication to clear water reserviors 60 and by valve(Do not show in figure)The connection is controlled, in raw water When water quality is preferable, Carbon-sand filter unit 40 or ultrafiltration film unit 50 can be surmounted respectively;Described biological filter unit 20 It is provided with aerator;The inlet portion of described tube settling unit 30 is provided with coagulant dosage device 31;Described charcoal sand The inlet portion of biofilter unit 40 is provided with ozone throwing device 41.
Described 60 Jing repumping houses 70 of clear water reserviors are connected with the distribution system of water supply 80.
The inlet portion of described clear water reserviors 60 is provided with disinfectant feeding device 61.
During using conventional treatment, the ammonia nitrogen of such high NH4 source water and the possible Jing of content of organics are often exceeded.This practicality is new Type by biofiltration, tube settling, ozone and activated carbon and ultrafiltration membrane technique highly integrated, so as to effective guarantee effluent quality Meet the requirement of every new standard.
In biological filter unit 20, the effect of raw water Jing aeration, is nitrified by biological oxidation, physical filtering and air oxidation Ammonia nitrogen, degradation of organic substances etc..Containing a small amount of biomembranous backwashing wastewater, follow-up sedimentation basin can be directly entered(I.e. inclined tube sinks Shallow lake unit 30), promote flocculation process so as to pass through " biological agent ".Tube settling unit 30 is made in raw water by dosing coagulant Molecule collision knot it is big, Jing tube settlings realize the reduction of raw water turbidity.Raw water Jing after haze reduction enters into charcoal sand Biofilter unit 40, the cooperative effect in ozone oxidation and charcoal sand filter element, by suction-operated and biological treatment, further drops Ammonia nitrogen, micro- Organic Pollutants, colourity, odor in low water etc., and improve the biological stability of water outlet.The Carbon-sand filter unit 40 The possibility of subsequent ultrafiltration film unit 50 " organic contamination " can be substantially reduced.The use of layer of sand, residue that can be in effectively catching water Turbidity, come off biomembrane and broken charcoal particle, effectively reduces the load of follow-up film process.Ultrafiltration film unit 50 can to turbidity in water, Bacterium, algae and sporangiocyst etc. are efficiently removed, therefore, the dosage of disinfectant can be substantially reduced, so as to reduce producing in a large number The risk of DBPs.
The concrete technology flow process of efficient combination processing system that the utility model is provided is:Raw water 10 first adopts biofilter Unit 20 carries out aerated reaction, and reacted water outlet enters tube settling unit 30, enters charcoal sand after water is treated by ozone after sinking Biofilter unit 40, water after filter carry out membrane filtration into ultrafiltration film unit 50, and water outlet after membrane filtration is folded final after clear water reserviors 60 are regulated and stored under The distribution system of water supply 80 is sent into by repumping house 70.
In the case of raw water quality is preferable, can be to biological filter unit 20 or Carbon-sand filter unit 40 or ultrafiltration film unit 50 are surmounted respectively.
Using a case history of efficient combination processing system of the present utility model, through the process of the system, work as original When 1.5 ~ 3.5mg/L fluctuates, water outlet ammonia nitrogen data are controlled in below 0.5mg/L water ammonia nitrogen value, are also had simultaneously for turbidity 25 ~ 30% removal.And conventional treatment is adopted, the removal to ammonia nitrogen is only 20% ~ 30%.As biological agent promotes to flocculate, this is Floc particle in system is formed better than conventional processing device, can effectively reduce by 20 ~ 30% medicine consumption.The application of ultrafiltration membrane system, makes The turbidity for obtaining the water outlet of this device is respectively less than 0.2NTU, better than 0.5 NTU controlling values of conventional equipment.
In sum, the efficient combination processing system that the utility model is provided is using after Biological Pretreatment coagulating sedimentation Ozone charcoal sand filters the combination of film processing system each unit, and energy effective process conventional treatment can not still meet effluent quality mark Accurate micro-polluted raw.
Although content of the present utility model has been made to be discussed in detail by above preferred embodiment, but it should be appreciated that on The description stated is not considered as to restriction of the present utility model.After those skilled in the art have read the above, for Various modifications and substitutions of the present utility model all will be apparent.Therefore, protection domain of the present utility model should be by appended Claim limiting.
