Embodiment
Embodiment 1:
Cullet and marble are milled to more than 200 mesh, powder is obtained after taking 18g glass powders and the mixing of 2g marble dusts
Body batch, biologic packing material is prepared for foamed, annealing.Cullet can be discarded plate glass, pattern glass,
Container glass or cathode-ray tube glass etc..The specific preparation method of water treating suspended formula filler is:
Powder batch obtained above is stacked into the mould in chamber type electric resistance furnace, powder batch is in heating furnace
Quick cooling is carried out after preheated, heating heating and foaming heating sintered and foamed heating thing is made, then by sintered and foamed heating
Thing naturally cools to the biologic packing material that room temperature can obtain having adsorption effect, actual temp control after being taken out from resistance furnace
Situation is:400 DEG C are warming up to 10 DEG C/min heating rate from room temperature, is incubated 30min;Again with 10 DEG C/min heating speed
Rate is warming up to 1000 DEG C, is incubated 10min;Then 850 DEG C are cooled to 25 DEG C/min rate of temperature fall, finally naturally cooled to often
25 DEG C of temperature, obtains the water treating suspended formula filler.The form of the filler is:The surface of filler with inside full of it is small, connect or
The stomata of closing.Filler overall mechanical strength is stronger.Filler contains the hole of foaming, in multiple sintering process, due to resistance
The distribution of stove heat itself is uneven, therefore the filling property that sintering obtains slightly has differences, but generally:The volume of filler is close
Spend for 0.5-0.8g/cm3, specific surface area 8.2m2/ more than g, porosity are more than 50%.Obtained filler water absorption rate is sintered to exist
More than 30%, acid resistance has excellent chemical stability more than 99.5%.And packing density is less than water, has and commonly uses
The same suspension characteristic of hollow suspension ball filler, it is fluidity good, it is not easily blocked, equipment is simple, low cost, and operating cost is low.
Its adsorption effect to Phosphorus From Wastewater is verified by tests below:
The preparation of Nitrogen-and Phosphorus-containing waste water:Take the concentration of Nitrogen-and Phosphorus-containing waste water, wherein potassium hydrogen phosphate that 100ml is prepared in 2 beakers
For 10mg/L, the concentration of ammonium chloride is after 50mg/L is well mixed, to stand.
In 2 beakers one be put into 6g biologic packing materials, remaining one be control group, 2 beakers are sealed with preservative film.Every
12 hours, totally 36 hours, the concentration of nitrogen and phosphorus in two groups of waste water is measured.
Ammonia nitrogen, total phosphorus concentration unit mg/L of the waste water of embodiment 1 in different periods
It is indicated above that filler has obvious and quick absorbability to the phosphorus in waste water, but under the proportioning, filler is to nitrogen
Adsorption capacity it is weaker.Therefore the biologic packing material can be used for Removal of Phosphorus in Wastewater.Specifically processing method is:Biologic packing material is filled
In the packing layer of artificial swamp, pending waste water is set to pass through the adsorptivity of biologic packing material itself first by the biologic packing material
Preliminary treatment can be carried out to the phosphorus in waste water, reduce its initial concentration;Then proceed to biologic packing material being placed in wetland, make micro- life
Thing is further handled the nitrogen in waste water, phosphorus and organic matter after its biofilm by microorganism in filler superficial growth.
Based on above-mentioned processing method, the biologic packing material of the reinforcing Phosphate Sorption can realize another purposes, i.e., will be above-mentioned
The biologic packing material that waste water and failure have been handled in artificial swamp is filled in, i.e. filler can not meet manually to the disposal ability of waste water
After wetland requirement, it is drawn off, and is clayed into power, sheds or turn in soil as soil conditioner.
Embodiment 2
In the present embodiment, cullet, marble and zeolite are milled to more than 200 mesh, take 18g glass powders, 2g marbles
Powder batch is obtained after powder and the mixing of 3g zeolite powders, biologic packing material is prepared for foamed, annealing.Cullet can
To be discarded plate glass, pattern glass, container glass or cathode-ray tube glass etc..Water treating suspended formula filler it is specific
Preparation method is same as Example 1.But actual temp control situation has differences.
Temperature control is in the present embodiment:
500 DEG C are warming up to 15 DEG C/min heating rate, is incubated 20min;Heated up again with 15 DEG C/min heating rate
To 1100 DEG C, 20min is incubated;Then 900 DEG C are cooled to 20 DEG C/min rate of temperature fall, finally naturally cool to normal temperature.Burn
Tie obtained filling property and the filling property that embodiment 1 obtains is essentially identical, each index is in above range.
Verified also according to the adsorption effect of biologic packing material of the test method of embodiment 1 to being prepared in this example, as a result
It is as follows:
Ammonia nitrogen, total phosphorus concentration unit mg/L of the waste water of embodiment 2 in different periods
It is indicated above that filler is respectively provided with obvious and quick absorbability, therefore the biologic packing material to the nitrogen in waste water, phosphorus
Available for simultaneously handle nitrogen and phosphorus in waste water.The biologic packing material is used as Performance of Constructed Wetlands Substrates.Waste water and failure are handled
Biologic packing material can clay into power, shed or turn in soil as soil conditioner.
Comparative example 1
The foamed glass that the present embodiment is generated using certain the commercially available environmental protection company being commercially available(With the filler of the present invention
It is similar), its adsorption effect to Phosphorus From Wastewater, obtained experimental result are verified according to the testing program of embodiment 1:
Ammonia nitrogen, total phosphorus concentration unit mg/L of the waste water of comparative example 1 in different periods
The adsorption capacity that commercially available foam glass is indicated above to ammonia nitrogen in waste water, phosphorus is weaker.And the preparation side of the present invention
The innovative adsorptivity having using zeolite in method, coordinating glass, what is be fabricated to is floated in the case where marble foams
Biologic packing material also has this effect of good absorption in addition to filler characteristic in itself to the phosphorus in water.This is to biology
A kind of improvement of filler, and provide the application field of new foam glass.The filler phase that commercially available filler is prepared with the present invention
Than adsorption capacity is far smaller than the present invention.Therefore, it is of the invention to have preferably to Phosphorus From Wastewater relative to existing foamed glass
Adsorption capacity, be it is a kind of environmental protection, low cost novel absorption material.
