Description
Technical field
The present invention relates to foamed glass field of material technology, especially a kind of foamed glass material for reducing water quality total phosphorus index
Material and preparation method thereof.The foamed glass material that the present invention comes out can reduce the phosphorus in sewage by suction-operated, inhale
The foamed glass of attached phosphorus can be recycled with nitric acid and citric acid with high-purity forms.
Background technique
A large amount of waste water are discharged in chemical fertilizer manufacturing, the phosphoric acid plant production of factory, while in paint industry, plating row
Industry in electronic product etch process, has a large amount of phosphorus-containing wastewater, phosphorus-containing wastewater mainly includes phosphate anion and ortho phosphorous acid
Radical ion, the discharge of phosphorus-containing wastewater will lead to the eutrophication of water body, cause environmental pollution, influence aquaculture development, simultaneously
It is detrimental to health, is up to state standards and could discharge so needing to carry out phosphorus-containing wastewater processing.
Phosphorus removing method is broadly divided into bioanalysis, chemical method, three kinds of modes of absorption method.
Bioanalysis dephosphorization is the principle of intake and release phosphorus based on biting phosphorus bacterium under aerobic and anaerobic condition, by it is aerobic-
The alternate run of anaerobism realizes dephosphorization.Bioanalysis dephosphorization process is rapidly developed since the 1970s, to original
There is the reasonable of waste water biochemical treatment equipment to utilize and (do not need a large amount of additional equipment investments), and can be completed at the same time to organic matter
The advantages that removal, lower operating cost, obtains consistent approval.This method under suitable conditions, can remove high in waste water
Up to 90% phosphorus.But in general, bioanalysis dephosphorization process operation stability is poor, and operation operation is stringent, by the temperature of waste water
It is big to spend the influences such as pH value, it is very strong to organic concentration in waste water (BOD) dependence, when content of organics is lower in waste water, or
When phosphorus content is more than 10mg/L, water outlet is difficult to meet the discharge standard of phosphorus, therefore, generally requires to carry out at secondary dephosphorization water outlet
Reason.
Chemical method dephosphorization refers mainly to generate indissoluble phosphorus using the metal ion and phosphate radical of the generations such as molysite, aluminium salt and lime
The method of hydrochlorate sediment removes the phosphorus in waste water.The method simple process, it is reliable for operation, and it is total to reach higher water outlet
Phosphorus requirement.But the process is precipitating-dissolution equilibrium reaction.On the one hand, the basicity in waste water causes part metals hydroxide
Precipitating, consumes a part of amount of medicament；On the other hand, to reach lower phosphate ion concentration, it is necessary to keep higher gold in waste water
Belong to ion concentration.Due to microscopic precipitate particle quasi-equilibrium phenomenon, apparent solubilty product is caused to be much higher than true solubility product, in order to reach
To the formation condition of calcium phosphate precipitation, the precipitation by metallic ion agent concentration for needing to add is commonly greater than 1-2 number of normal solubility product
Magnitude, therefore, medicament are costly；It is also higher to thereby result in remaining metal ions concentration (such as iron ion), increases effluent color dilution
Add, exceeded concentration of metal ions can also may generate chronic toxic action to biology；The chemical sludge that chemical precipitation generates contains
Water is big, and dehydration is difficult, it is difficult to handle, be easy to produce secondary pollution.
Adsorption and dephosphorization method is to carry out physical suction to the phosphorus containg substances in waste water using materials such as activated carbon, activated aluminas
It is attached, the content of phosphor in sewage is reduced with this.This method relies primarily on the adsorptivity of water-purifying material, and consumable material is costly.
