Description
Technical field
The present invention relates to one kind being directed to reservoir（Lake）The water purification of the different odor type organic removal of the micro- pollution of source water is newly square
Method belongs to Water purification technical field.
Background technology
Reservoir（Lake）Organic matter in water body is from two aspects：First, the extraneous organic matter to discharge into water：Two
It is the organic matter of organic matter and Sediments release that the biocenose being grown in water body generates.Organic matter in source water
It is broadly divided into two major classes：One kind is natural organic matter, including humus, microorganism secretion object, the plant tissue of dissolving and dynamic
The waste etc. of object；Another kind of is artificial synthesized organic matter, including the synthetic of pesticide, commercial use and some industrial wastes
Object, artificial synthetic organic materials are mostly harmful organic substance, and organic matter is caused including three.
The pollution of source water not only gives the health care belt of the mankind to carry out larger harm, but also it is to traditional water-purifying process and water quality
Influence caused by various losses be difficult to the appraisal.In addition also increase water producing cost, influence industrial and agricultural production, cause through
Ji loss, exacerbates the crisis of water resource.
Earth's surface water factory of the country generally uses the conventional water treatment process of " coagulation+precipitation+filtering+disinfection " at present, mainly goes
Except object is suspended matter, colloidal impurity and the bacterium in source water.The limitation of conventional purification technique is that it goes in water removal to dissolve
The efficiency of property organic matter is low, and chlorination process itself also results in the organohalogen compounds in water to human health damage bigger
It is formed, therefore conventional drinking water treatment technique cannot be adapted with existing water source and water standard, it is necessary to increase deodorization
Except organic matter emergency processing equipment, to cope with the variation of raw water quality.
Using suitable physical, the processing method of chemistry and biology on the basis of water factory's traditional handicraft, to the pollutant in water
It is removed, so that subsequent conventional treatment process can preferably play a role, mitigates the burden of conventional processes, play water
The removal effect to water pollutant is improved while treatment process mass action again, improve drinking water quality and improves drinking water
It is safe and healthy.Invention content
For current traditional water treatment technology to the place present in micro-pollution reservoir water organics removal, ammonia nitrogen and odor etc.
It manages ineffective, generates disinfection by-products, the problems such as operating cost is high, the present invention provides the different odor class of micro polluted source is organic
The water purification new method of object removal.The present invention reduces the usage amounts of Pre-Treatment of Activated charcoal absorbing process, and extend its service life,
The load for significantly reducing conventional treatment and successive depths processing, improves effluent quality, and reduction causes secondary pollution to environment.
The present invention uses following technical scheme：
A kind of water purification new method of the different odor type organic removal of micro polluted source, which is characterized in that it is according to as follows
What step was realized：
1）Polluted source water is pre-processed into the adsorption reaction pond containing Powdered Activated Carbon；In the adsorption reaction pond
Also contain activation body refuse；
2）By treated in adsorption reaction pond, water is directly entered coagulation reaction tank, be then added coagulant, flocculation aid and
Activate and start coagulating, biological adsorption and biodegradation process after body refuse, the water after reaction treatment enter sedimentation basin into
Row precipitation；
3）From sedimentation basin come out water carries out active oxidation processing with oxidant before filtration treatment, finally by filter,
Clear water after disinfection is purified completes entire purification process.
The step 1）With step 2）In activation body refuse come from sedimentation basin.
It is described activation body refuse specific activating treatment method be：It is put into water factory's sedimentation basin part body refuse as primary sludge
Priming reaction pond need to control wherein nutriment C for guarantee biochemical reaction:N:The ratio of P is 100:5:1, control is anti-
It is 6.5 ~ 7.5 to answer pond pH, and temperature is about 12 ~ 19 DEG C；Dissolved oxygen control is 2 mg/L, bored exposure 3-5d, quiet heavy, effluent；Then
Fresh spoil disposal water identical with displacement is gradually injected daily, and bored exposure, quiet heavy and drainage procedure, continuous operation 4-21 is repeated
It, when determining that sludge 30min settling ratios reach 10%, sludge concentration and reach about 3000-4000 mg/L and supernatant C OD removal rates
Reach 60%, and keep after stablizing, shows that body refuse bioactivation process is basically completed at this time, activation body refuse culture success.
The step 1）Middle Powdered Activated Carbon dosage is 3 ~ 5mg/L, adsorption reaction pond adsorption time 10-15min.
The step 1）Middle adsorption reaction pond adds activation body refuse a concentration of 4 g/L, dosage 1-5%.
The step 2）Middle coagulant is the PAC of 15mg/L；The flocculation aid is the PAM of 0.06mg/L；The activation mud
Slag a concentration of 4 g/L, dosage 1-3%；The hydraulic retention reaction time is 5-10min.
The step 3）In oxidant be Potassium Monopersulfate, dosage 0.25-1.5mg/L.
The step 3）In active oxidation processing method be：Oxidant, ultraviolet light illumination wavelength are irradiated using ultraviolet light
For 254nm, irradiation time 2min.
The polluted source is reservoir water or Lake Water.The percentage of dosage of the present invention is weight percentage.
It is pre-processed using powder electroless plating in the present invention, to cope with the pollution situation of raw water and go the cause in water removal smelly
Substance, activated carbon contain a large amount of micropores, have huge specific surface area, for the substance of some hardly possible removals in sewage, such as surface
Activating agent, phenol, pesticide, fuel, refractory organic and heavy metal ion etc. have higher treatment effeciency.Activated carbon exists
Enter sedimentation basin after adsorption reaction, the organic matter that then amount of activated charcoal, the body refuse of sedimentation basin discharge are adsorbed is through biology
Palingenesis degrade, activity recovery charcoal adsorption capacity, activated carbon, body refuse after activation re-start participate in enhanced coagulation reaction,
Body refuse in sedimentation basin is carried out activation recycling by biological adsorption, biodegradation.
The present invention is compared compared with traditional handicraft, is had the following advantages that：
1）Activated carbon and body refuse bioactivation technique are used in the present invention, by the amount of activated charcoal of sedimentation basin discharge, body refuse
The organic matter adsorbed is acted on through bio-regeneration and being degraded, activity recovery charcoal adsorption capacity, activated carbon, body refuse after activation again into
Row participates in enhanced coagulation reaction, biological adsorption, biodegradation, improves coagulation effect, while increasing the utilization of activated carbon
Rate can effectively lower the dosage of Powdered Activated Carbon, reduce operating cost, and water source purifying effect is good.
2）Compared with traditional Potassium Monopersulfate is used as disinfection of drinking water agent, and the present invention is using UV activation before filter
Potassium Monopersulfate oxidation processes, are used for the hardly degraded organic substance of oxidized residual, and active oxidation agent can be by remaining difficult drop in water
The removal of solution oxidation operation is oxidized to small organic molecule, while improving the dissolved oxygen levels of water body, and follow-up filter tank is made to have
Biofilter function, the small organic molecule after degradation oxidation, has reached the purpose of residual organic matter removal.
