Description
Technical field
The invention belongs to water-treatment technology fields, a kind of water treatment system more particularly, to micro-polluted source water and
Method for treating water.
Background technique
The sewage of industrial production and rural activity etc. is directly discharged to Natural Water if it cannot be effectively addressed
Know from experience and cause the pollution of water head site, this is the main reason for causing the micro- pollution in drinking water source.In the different regions in China, due to certainly
So, different characteristics is presented in the pollution of the difference of social environment, water head site, and source quality problem is also not quite similar.On the whole, micro-
The contaminant water mainly pollution by natural organic matter and micro hardly degraded organic substance.Although the total amount of pollutant in micro-polluted source water
It is lower, but pollutant kind is various, property is complicated, and conventional water treatment process (coagulation, precipitating, filtering, disinfection) is difficult to effectively net
Change micro-polluted source water
Micro-Polluted Water Treatment commonplace at present is to carry out strengthening or using deep on the basis of common process
Treatment process is spent, has absorption method, coagulation assisted method, membrane separation process etc. using wider processing method at present.Absorption method is
Using the adsorbent with adsorption capacity by the Adsorption of Organic in water body into adsorbent, thus make organic pollutant with
Water body separation.The advantages of absorption method is that equipment is simple and convenient to operate, but absorption method also has disadvantage, due to adding in water process
Adsorbent, it is also contemplated that the recycling of adsorbent, this adds increased the operating costs in water treatment procedure, bring to practical application
It is difficult.Enhanced coagulation is to add excessive coagulant by Xiang Shuizhong and control certain pH value, improves coagulation in conventional treatment
The treatment effect of process, removes suspended particulate substance and organic pollutant in water removal to the maximum extent, and enhanced coagulation technique has operation
It is easy but due to additionally adding PH regulating agent and coagulant, the increase of water factory's operating cost certainly will be will cause.Ultrafiltration (UF) skill
Art is widely used in drinking water treatment and wastewater treatment and reuse etc., to suspended matter, colloidal substance, inorganic particle and
Pathogenic microorganism has good rejection effect.However when hyperfiltration technique is used alone, since fouling membrane can cause flux
Decline and transmembrane pressure rise, and shorten the service life of ultrafiltration membrane, so that operating cost and water producing cost increase, limit it
Development.
Summary of the invention
The purpose of the present invention is overcoming the deficiencies of existing technologies, water treatment system and the side of a kind of micro-polluted source water are provided
Low energy consumption, stable for method, water treatment system of the invention and method, and treated, and effluent quality is excellent, and it is " raw to be able to satisfy China
Sanitary standard for drinking water living " (GB5749-2006) requirement.
To achieve the goals above, an aspect of of the present present invention provides a kind of water treatment system of micro-polluted source water, the water
Processing system includes: the first chemical coagulation device, the second chemical coagulation device and ultrafiltration membrane separating device；Wherein, described first
Chemical coagulation device is connected to the second chemical coagulation device, the second chemical coagulation device and Ultra filtration membrane dress
Set connection.
Another aspect of the present invention provides a kind of method for treating water of micro-polluted source water, using above-mentioned water treatment system into
Row water process, the method for treating water include:
(1) by raw water into the first chemical coagulation device, the first coagulation treatment is carried out, the first mixing is obtained
Liquid；
(2) first mixed liquor is delivered in the second chemical coagulation device, carries out the second coagulation treatment, obtains
Second mixed liquor；
(3) second mixed liquor is delivered in ultrafiltration membrane separating device, carries out solid-liquid separation treatment.
Technical solution of the present invention has the following beneficial effects:
(1) method for treating water of the invention: passing through optimised coagulation and Ultra filtration membrane technique is cooperateed with to remove micro polluted source
Polluter in water, making that treated, water outlet is able to satisfy China " standards for drinking water quality " (GB5749-2006) requirement,
The process structure is simple, stable effluent quality, and the loss of film device operating pressure is small, and the decline of membrane flux speed is low, membrane module backwash
Frequency is low.
(2) present invention carries out coagulation to raw water by iron salt coagulant first in the first coagulating basin, utilizes Fe3+In solution
The reaction of spontaneous carry out in-situ hydrolysis generates positively charged hydrolysate in ontology, using these hydrolysates with it is negatively charged in water
The organic pollutant of lotus carries out charge neutrality reaction, reduces the current potential on organic matter surface, makes water-borne glue body pollution object is de- to be surely gathered into
Big particle.Hydrolysate has biggish specific surface area simultaneously, is conducive to it and adsorbs organic matter and suspended particulate, improves coagulation
Effect.
(3) due to making the weakly acidic (5- of pH value of mixed liquor in the first coagulating basin after iron salt coagulant hydrolysis
6.5), under the conditions of low pH value, increase the positively charged density of the hydrolysate to be formed institute, while the matter of organic pollutants
Sub-ization degree due to pH reduction and increase rapidly, being conducive to organic matter is adsorbed on the hydrolysate of coagulant, can mention in this way
The removal rate of Gao Shuizhong dissolved organic matter, and then improve the total removal rate of Organic substance in water.
(4) in the present invention, the first mixed liquor enters in the second coagulating basin, utilizes the solutions of weak acidity (PH=5- of mixed liquor
6.5) it is produced as the aluminum salt added hydrolysis with Al3+Middle aggressiveness based on AlbFloccule body, the floccule body have very strong
Positive charge and adsorpting aggregation ability, thus have very strong charge neutrality adhere to bridge formation ability, can be to the organic contamination in water body
Object shows superior cohesion-flocculation.
(5) in the present invention, the hydrolysate of molysite and aluminium salt, surface area is huge, has absorption to the metal in water, mixes
Brilliant, the effects of sweeping along, hydrolysate surface OH-Concentration is much higher than in water, and has the ability for continuing to adsorb other metal ions, from
And reduce the concentration of remainder fe and aluminium in water outlet.
(6) molysite in the present invention and the hydrolysate of aluminium salt can generate copolymerization effect, the adsorption bridging of copolymer, and volume is swept
Effect is all very strong, and the floccule body formed in addition is closely knit, and the wadding body formed in conjunction with the organic pollutant in water body is more stable, intensity
It is high, it is not easy to be destroyed again by external force；When wadding body is adsorbed to ultrafiltration membrane surface, the cake layer of formation is not easy by pressure pressure
Broken, compacting, thus cake layer is loose porous, surface is also relatively coarse, slows down fouling membrane significantly, water yield is improved,
Cleaning frequency membrane is effectively reduced simultaneously.
(7) coagulant used by present invention process is traditional inorganic salt coagulant, has simple production process, valence
The characteristics of lattice relative moderate.The technique can flexibly change dosage with the difference of raw water pollutant concentration, effectively from water
The some substances for going oil removal, colloid and molecular state and ionic state guarantee that effluent quality meets " Drinking Water health mark
It is quasi- " (GB5749-2006) requirement.
Other features and advantages of the present invention will then part of the detailed description can be specified.
