Background technique
Phosphorus is widely applied in Chemical Manufacture especially water treatment agent and pesticide producing, since this kind of phosphorous chemical industry enterprise produces
Be all long-term large-scale production and to use containing organic phosphorus product, serious pollution is caused to environment especially water body.At China
The stage in development is greatly produced waste water and is even not yet just directly arranged through any processing due to factors such as economy, technologies
It puts, results in more serious environmental pollution.Conventional Anaerobic Treatment and oxygen processing, Aerobic Process for Treatment be easy to cause sludge strain
It is poisoned and loses the ability of purification waste water.
Currently, sewage dephosphorization technology mainly has chemical method and bioanalysis both at home and abroad, chemical method mainly has coagulating sedimentation, absorption
The methods of, it is mainly suitable for the phosphorus-containing wastewater of processing inorganic states, bioanalysis mainly there are the techniques such as A/O, A2/O, is mainly suitable for handling low
The phosphorus-containing wastewater of concentration organic.
It is directed to the research that high concentration organism P wastewater is handled at present never to interrupt, but not yet find one kind efficiently to make waste water
In the organic phosphorus processing method for being converted into Phos, especially country to the discharge standard of total phosphorus improve to 0.5 mg/L with
Afterwards, very urgent to the research of high concentration organism P wastewater processing method.
Summary of the invention
The purpose of the present invention is being directed to the intractable status of high concentration organism P wastewater, provide it is a kind of efficiently handle it is highly concentrated
Spend the method for organism P wastewater, the specific steps are as follows:
(1) high concentration organism P wastewater pH is adjusted to 2 ~ 2.5, is reacted by iron carbon reactor；
(2) H is added2O2The reaction was continued, adjusts pH to 7 ~ 8 after the reaction was completed；
(3) it adds PAC and PAM and carries out flocculation sedimentation；
In iron carbon reactor described in step (1), iron-carbon ratio surface area be 1.2 m2/g -1.5 m2/g, specific gravity 1.2-1.5,
Iron carbon content >=80%.
The iron carbon reactor bottom is additionally provided with aeration tube, and aeration quantity is 3 ~ 4 times of waste water volume.
The H2O2Content is 25-30%, and dosage is the 0.3-0.5% of high concentration organism P wastewater weight.
The PAC concentration is 1.8-2.5%, and dosage is the 0.1-0.2% of high concentration organism P wastewater weight.
The PAM is cationic, and molecular weight is 1100-1200 ten thousand, and mass concentration 0.2-0.4%, dosage is height
The 0.1-0.2% of concentration organism P wastewater weight.
It is compared with other methods, this method has the advantage that
(1) this method is to be applied to high concentration organism P wastewater field for the first time, is suitable for various high concentration organism P wastewaters；
(2) this method can also effectively remove the organic matter in waste water, especially hardly degraded organic substance；
(3) this method treatment effect is stablized.
