Description
Technical field
The present invention relates to a kind of method of dephosphorization, the method for organophosphor in especially a kind of adsorbing and removing waste water.
Background technology
Common waste water dephosphorization method is mainly removed including chemical method dephosphorization, bioanalysis dephosphorization and absorption method both at home and abroad at present
Phosphorus.Although chemical dephosphorization method is very high to the removal rate of phosphorus, operating cost is high；Remaining metal ion not only makes effluent color dilution
Increase, and generate and be largely difficult to the sludge handled, be easy to cause secondary pollution, and can may also generate chronic murder by poisoning to biology
Effect；Bioanalysis dephosphorization treatment effect is not easy to stablize, processing procedure by the extraneous factors such as temperature, dissolved oxygen, pH values influenced compared with
Greatly, water outlet total phosphorus is difficult to reach country's promulgation《Urban wastewater treatment pollutant emission standard》(GB18918-2002) level-one B
Discharge standard (TP≤1mg/L), less with putting forward level-one A discharge standards (TP≤0.5mg/L).
CN 104743682A disclose a kind of method handling organophosphor in waste water.This method passes through waste water is at least logical
Enter processing in a biochemical reaction unit, converts organophosphor to Phos；The biochemical reaction unit includes oxygen-containing and first
The gas of alkane, microorganism；The microorganism includes methane-oxidizing bacteria；The gas of the oxygen-containing and methane, microorganism and contain
The waste water of organophosphor is mixed in biochemical reaction unit；In the waste water in the form of organophosphor existing for phosphorus concentration be more than
5mg/L。
