Description
Technical field
The invention belongs to field of industrial waste water treatment.Relate to a kind for the treatment of process containing high density phosphite waste water.
Background technology
Sodium hypophosphite can carry out chemical nickel plating, copper facing and copper powder as reductive agent to be prepared, and is widely used in electronics, machinery, oil, chemical industry, the industries such as medicine, phosphite containing high density in the waste water produced and a small amount of phosphoric acid salt, its content is considerably beyond discharge of wastewater requirement.Patents document about phosphite wastewater treatment is less, but for the waste water containing reductibility phosphorus, adopts the patent documentation that method for oxidation is translated into positive phosphorus, recycling chemical method precipitation is removed relatively many.
Chinese invention patent high P content waste water treatment process (application number 201110424246.8), propose to adopt iron(ic) chloride and/or ferric sulfate as oxygenant, be ortho-phosphoric acid root by reductibility phosphorus oxidation, ortho-phosphoric acid root generates with iron ion and precipitates dephosphorization, and applicable total phosphorus concentration is 26-163mg/L.
Chinese invention patent (application number 200810063021.2) discloses the ozone-enhanced electric coagulating/flocculating method for processing of phosphorus-containing wastewater, propose to adopt ozone oxidation to strengthen electricity flocculation and produce more ironic hydroxide flco, thus more effectively remove phosphate contaminants.
The treatment process (application number 201110383538.1) of a kind of phosphorus-containing wastewater of Chinese invention patent application, organophosphorus pesticide factory effluent for 500-10000mg/L is proposed, Fe-C micro electrolysis is adopted to carry out pre-treatment and Fenton reagent oxidation, transfer organophosphorus to orthophosphoric acid salt, then carry out flocculation sediment.
Process and the disposal of the chemical sludge produced are not considered in great majority research.With molysite be flocculation agent dephosphorization process produce chemical sludge contain a large amount of ironic hydroxides and tertiary iron phosphate, generally cannot reclaim, process as general solid waste; With lime be flocculation agent dephosphorization process produce chemical sludge main component be calcium phosphate powder, agriculture fertilizer is made in general reuse.
Summary of the invention
The object of this invention is to provide a kind for the treatment of process containing high density phosphite waste water, according to the difference of phosphorus containg substances, reclaim its chemical precipitation product selectively, and meet the emission request of waste water.
The present invention is a kind for the treatment of process containing high density phosphite waste water, it is characterized in that:
1) adopt three grades of chemical dephosphorization techniques, realize water outlet total phosphorus and be less than 1mg/L, its detailed process is as follows:
A) one-level dephosphorization: waste water first order reaction pond add add settling agent and PAM in excessive precipitation agent, one-level flocculation basin after precipitate;
B) secondary dephosphorization: first stage precipitation tank water outlet enters second order reaction pond, adds ozone in pond, produce insolubles, mixed solution precipitates after secondary flocculation basin adds settling agent and PAM;
C) three grades of dephosphorization: second-level settling pond water outlet enters three grades of flocculation basins, add PAC and PAM and carry out flocculation sediment, to remove small-particle insolubles residual in waste water, reduce total phosphorous in waste water further; Final outflow water is carried out pH value adjustment as requested or is processed except hard;
2) handled by is the factory effluent that acrylamide production equipment hypophosphite reduction method prepares copper catalyst containing high density phosphite waste water, and total phosphorous is 850 ~ 2100mg/L, and pH value is 12.5 ~ 14.0;
3) precipitation agent described in is calcium chloride, and settling agent is one or more in water-ground limestone, life/white lime, terra alba;
4) precipitation agent added in first order reaction pond in the mass ratio of Ca and total phosphorus in former water for 1:1 ~ 2:1;
5) in the ozone added in second order reaction pond and former water, the mass ratio of total phosphorus is 0.5:1 ~ 1.5:1;
6) settling agent added in I and II flocculation basin is respectively 0.02% ~ 0.1% in Ca and the mass ratio of total phosphorus in former water;
7) reaction times in first order reaction pond and second order reaction pond is 0.5 ~ 1.5h.
Compared with prior art, the present invention has following characteristics:
1) calcium chloride solubleness is large, good water solubility, adopts CaCl
2as precipitation agent, the chemical sludge water ratio of generation is low, and the quantity of slag is little; Adding of settling agent, improve the sedimentation function of mud, contribute to solid-liquid separation;
2) calcium chloride precipitation agent is only disposable in first order reaction pond excessively adds, and contributes to more orthophosphite in one-level dephosphorization process and is converted into Arizona bacilli precipitation and removes, greatly reduce the consumption of ozone in secondary dephosphorization process;
3) adopt ozone as oxygenant, oxidation efficiency is high, and in tail gas, ozone conversion is oxygen discharge, and clean environment firendly produces without additional contaminants;
4) adopt three grades of dephosphorization process, the classification taking back and process generating solid waste can be realized.The chemical sludge that one-level dephosphorization process produces, main component is Arizona bacilli, and the rust proof paint that can be used as high-efficiency environment friendly is recycled; The chemical sludge that secondary dephosphorization process produces, main component is calcium phosphate powder, can be used as chemical fertilizer and reclaims; The chemical sludge amount of three grades of dephosphorization process generations is minimum, and main component is calcium phosphate powder and polymerize aluminum chloride, can be used as general solid waste and carries out process disposal;
5) treatment effect is good, and total tp removal rate reaches more than 99.9%.
