Abstract
A method of removal water source gathering ground water body in phthalate pollutant, the method the following steps are included: (1) by the water of gathering ground by sedimentation basin precipitating, the supernatant collected;(2) supernatant is filtered by vibrating filter membrane, removes suspended material therein, obtains filtrate;(3) filtrate is passed through decontamination duct, the laggard horizontal high voltage mercury lamp light source illumination-based disinfection of oxidant is added;(4) water obtained after disinfection is subjected to biochemistry absorption by the adsorption tower of bio-resin, recycling elution processing is carried out to bio-resin, the water after absorption is then passed through the safety of water source reserve pool.Method of the invention can effectively remove phthalate pollutant in the water body of water source gathering ground, by the way that the safety of water source deposit is isolated, it can be secondarily contaminated to avoid water source, the water body of water source gathering ground can be subjected to state isolation simultaneously, guarantee that water source can not only reach environmental requirement, moreover it is possible to meet safe application needs.
Description
Technical field
The present invention relates to purification of water quality processing technology fields, are specifically related to phthalandione in a kind of water body of removal water source gathering ground
The method of esters pollutant.
Background technique
Phthalate (Phthalate Esters, hereinafter referred to as PAEs) is that output is big in the world, people of wide application
Work anthropogenics, can be used as plasticizer, solvent, auxiliary agent, be widely used at present plastic products, farm chemical carrier,
In the products such as pest repellant, packaging material for food, detergent, lubricating oil, paint, coating.With the continuous development of industrial and agricultural production
With being widely used for plastic products.
Phthalate organic matter is widely used in plastic products, is especially occupied in polyvinyl chloride (PVC) high
Ratio.Phthalate ester in plastics over time, can cause the dirt to natural environment by moving to external environment in plastics
Dye.Have been demonstrated that there is the detection of phthalate organic matter in big gas and water, waterworks, soil and food.Due to phthalate ester
Residual life, is longer in the natural environment, and biological terephalic acid ester has stronger enrichment, once into natural ecosystems, it is right
The harm of human health bring is inestimable.Therefore, attention is transferred to in environment by more and more researchers
Come in the degradation problem of existing phthalate ester.In the method for handling this pollutant, photocatalysis oxidation technique is simple easy because of it
Feature capable, economical and practical, without secondary pollution causes the common concern of scholar.
Phthalate (PAEs) pollutant common in the water body of water source gathering ground mainly has two fourth of phthalic acid at present
Ester (DBP) and dioctyl phthalate (DOP), common water purification treatment technology are to have carried out chlorination, flocculation sedimentation to raw water
And filtration treatment, but according to the measurement to the concentration of DBP and DOP in water sample after every cell processing, such water-purifying process is to upper
Stating two kinds of PAEs has apparent removal to act on, but output water DBP is still in exceeded state, it is therefore desirable to further explore new water
The removing method of phthalate pollutant in the water body of source gathering ground, the method for physics are no longer satisfied the demand of environmental protection, need
The method of biology, chemistry, physics is combined, to reach satisfied treatment effect.
Summary of the invention
To solve the shortcomings of the prior art, the purpose of the present invention is to provide in a kind of water body of removal water source gathering ground
The method of phthalate pollutant.
To achieve the above object, the present invention completes by following technical solution: a kind of removal water source gathering ground water
The method of phthalate pollutant in body, the method the following steps are included:
(1) by the water of gathering ground by water pump be pumped into sedimentation basin, precipitating bottom of pond portion be conical design, can make sediment according to
It is precipitated by gravity, conical design can be such that sediment quickly assembles and be conducive to solids discharge, and precipitating reagent is added and carries out
Precipitating sediment is discharged from precipitating bottom of pond portion by the mud valve with filtering function, the supernatant then collected;
