Description
Technical field
The present invention relates to sewage treatment area, the configuration of more particularly to a kind of solid dephosphorization matrix and its processing method.
Background technology
Industrial and agricultural wastewater, sanitary sewage kind contain substantial amounts of phosphorus, and these unnecessary P elements accumulate on a large amount of lake rivers
In.In general, the total phosphorus concentration, which is more than 0.01-0.02ppm, can cause eutrophication.Body eutrophication can cause algae
And other planktonic organisms breed rapidly, algae shielded from sunlight, water-bed plant is set to be die because photosynthesis is hindered, fish
And other biological mortalities, and be decomposed by the microorganisms after death, oxygen in water is reduced again, is released after animals and plants corruption
Nitrogen, the material such as phosphorus can be utilized again for algae again, water quality is drastically deteriorated, meanwhile, organic substance can also decompose in anaerobic condition
Caused harmful substance.In addition, because containing NO3-N and NO2-N in eutrophic water, people and animals drink these materials and contained for a long time
Amount can also be poisoned pathogenic more than the water of certain standard.
At the same time, phosphorus is usually used in fertilizer, and phosphate ore in the world is exhausted at present and can be at ensuing 100 years
Inside it is completely depleted, China's phosphorus ore can not meet one in 20 kinds of mineral products of national economic development demand after being listed in 2010
Kind, food supply is also affected.
The method of dephosphorization includes physico-chemical process, biochemical process, bioanalysis and processing etc. naturally.Physico-chemical process often with chemical precipitation, from
Sub- exchange, electrofloatation, adsorbent absorption and in-depth filtration etc.；Biochemical process often uses activated sludge process, can also use culture algae
It is isolated after intake phosphorus, or the methods of culture iron bacteria precipitation high ferro phosphate, but such method is by C/N, C/P, sun
The limitation of the conditions such as light, it is difficult to which continuous and effective goes dephosphorization；Bioanalysis such as cultivates algivorous insect, positive effect, but algae is eaten
Worm to the greatest extent also dies, it is difficult to is after season being also present, aquatic organism then can form secondary pollution because rotting；Naturally processing utilizes wet
Ground or artificial swamp, adsorption by soil diafiltration etc., effect is good, but needs to manage well and condition difficulty is sought.
The content of the invention
For in place of above the deficiencies in the prior art, the invention provides a kind of dephosphorization efficiency is high, preparation is simple, user
Just, the cheap novel solid dephosphorization matrix configuration of cost and its processing method.
A kind of solid dephosphorization filler, including inorganic coagulation material, retarder, porous material, perforating agent and dephosphorization material：
Further, the inorganic coagulation material is：Portland cement, aluminate cement, sulphate aluminium cement, fluoaluminic acid
One or more of mixtures in salt cement and ferrous aluminate cement.
Further, the retarder is：One or more in sodium citrate, oxalic acid, tartaric acid, boric acid and salicylic acid
Mixture.
Further, the dephosphorization material includes bodied ferric sulfate, magnesium sulfate and lanthana.
Further, described solid dephosphorization filler, it is characterised in that count by weight percentage, including inorganic gel
Material 20-30%, retarder 0.04-0.1%, porous material 15%-30%, perforating agent 1%-5% and dephosphorization material 10.1-
20.5%.
Further, described solid dephosphorization filler, it is characterised in that the porous material is bentonite, diatomite, boiling
One or more of mixtures in stone flour.
Further, described solid dephosphorization filler, it is characterised in that the perforating agent is sawdust, angiosperm crust
One or more of mixtures in powder, crop stalk powder.
Further, described solid dephosphorization filler, count by weight percentage, including inorganic coagulation material 20-30%,
It is retarder 0.04-0.1%, bentonite 5%-10%, diatomite 5%-10%, zeolite powder 5%-10%, sawdust 1%-5%, poly-
Close ferric sulfate 5%-10%, magnesium sulfate 5%-10% and lanthana 0.1-0.5%.
Further, described solid dephosphorization filler is applied to prepare solid dephosphorization matrix.
A kind of preparation method of solid dephosphorization matrix, comprises the following steps：
(a) above-mentioned solid dephosphorization filler is well mixed；
(b) plus water stirs, the colloidal state until forming microfluidic, now the weight ratio of the solid dephosphorization filler and water
For 1:0.1 to 1:Between 0.5, preferably solid dephosphorization filler and the weight of water ratio are 1:0.15 to 1:0.35；
(c) colloidal substance is filled in mould, after standing, the demoulding obtains dephosphorization block；
(d) dephosphorization block is placed under standard conditions and conserved；
Further, the preparation method of described solid dephosphorization matrix, in the step (a), the inorganic porous material
Cross 200 mesh sieves.
Further, the preparation method of described solid dephosphorization matrix, in the step (c), time of repose is that 2-24 is small
When.
Further, the preparation method of described solid dephosphorization matrix, in the step (d), when being conserved under standard conditions
Between be 1-7 days.
Further, after the completion of the maintenance of dephosphorization block, porous solid can also be obtained by sintering.Sintering temperature 300-
500℃。
Solid dephosphorization matrix provided by the invention can directly be added to lake-bottom, or be attached in mesh bag or plastic crate
In sink to lakebed again, can also be as the filler of artificial swamp.
Solid dephosphorization matrix powder provided by the invention can be used as filtering material, for example wetland is used as in artificial swamp
Filler, dephosphorization medium is used as in filter plant.
Compared with prior art, the advantage of the invention is that：
1) raw material sources of the present invention are extensive, cheap and easily-available, and cost is cheap.
2) dephosphorization material is attached in matrix in the present invention, wherein, metal ion, can be continuous after being combined with phosphate radical
Ground generates insoluble petal phosphate substances and is deposited in inside network structure, makes to form concentration between particle is inside and outside
Difference, phosphate radical constantly enter inside particulate matter, and dephosphorization efficiency is high.
3) the slightly solubility material of the stabilization formed except phosphorus substance and its with P elements in water is locked in product by the present invention
Intragranular portion, backed within so as to avoid phosphate radical in water.
4) solid dephosphorization matrix provided by the invention can make different shape different size according to different use environments
Product, can also be processed into fine particle formed pulvis or be made into suspension use, it is easy to use.
