Lime is added to neutralize, waste landfills.The method can generate a large amount of phosphorus containing sludges, increase landfill cost, or even can cause public hazards.In view of
This kind of waste liquid contains higher phosphate composition, therefore how research improves the comprehensive utilization to waste phosphoric acid, to ecological environment can
Sustainable development has important research significance.
Summary of the invention
Goal of the invention of the invention is to provide a kind of processing method of waste phosphoric acid, handles animal wastes with waste phosphoric acid, reaches
To the treatment of wastes with processes of wastes against one another, make ecological environment sustainable development.
To realize that the goal of the invention, the present invention provide a kind of processing method of waste phosphoric acid comprising: by animal wastes into
Row gasification, and combustion obtains the first product；The first product and kind material is set to carry out being mixed to get the second product by the weight ratio of 9:1；It presses
The second product of 100g adds 0.05-0.5 moles of H3PO4Ratio increases waste phosphoric acid in the second product, and is stirred, and makes waste phosphoric acid
It is impregnated with the second product completely and obtains third product；Stirring terminates post curing third product and obtains fertilizer.
Preferably, it is heated to three products and cures three products, curing number of days is 2-3 days.
Compared with prior art, method provided by the invention can reach following the utility model has the advantages that handling animal excreta with waste phosphoric acid
Just, reach the treatment of wastes with processes of wastes against one another, make ecological environment sustainable development.
Detailed description of the invention
Fig. 1 is the flow chart of the processing method of waste phosphoric acid provided by the invention.
Specific embodiment
The present invention will be described in detail With reference to embodiment.
The processing method of waste phosphoric acid provided by the invention includes: to be burnt animal wastes to obtain the first product；It presses
The first product of 100g adds 0.05-0.5 moles of H3PO4Ratio increases waste phosphoric acid and is stirred in the first product, keeps waste phosphoric acid complete
Being impregnated with the first product obtains the first mixture entirely；Stirring terminates the first mixture of post curing and obtains kind of a material；By the weight ratio of 9:1
The first product and kind material is set to carry out mixing to obtain the second product；Add 0.05-0.5 moles of H by the second product of 100g3PO4Ratio is second
Increase waste phosphoric acid in product, and be stirred, so that waste phosphoric acid is impregnated with the second product completely and obtain third product；Stirring terminates after-ripening
Change third product and obtains fertilizer.The animal wastes, which can be, stores class animal wastes, is also possible to poultry excrement.
40 to 60 degrees Celsius are warmed to third product and cures three products, and curing number of days is to obtain at phosphoric acid for 2-3 days
Manage object.Phosphoric acid processed material can directly as Fertilizer application, but after preferably drying and removing moisture, by its with other fertilizers at
Cooperate fertilizer, that is, can also suitably add other fertilizer, them is made to be mixed and made into cooperation fertilizer.
The experiment that the method provided according to the present invention carries out is described below:
Experiment one:
Prepare 90g poultry excrement combustion ash (pH12.03) and 10g kind material respectively, adds the phosphoric acid water of the amount of Table 1
Solution (phosphoric acid concentration 54.4%).It is ripe after curing 1 day after measurement mixing just stops and is warmed to 45 degrees Celsius and cures 6 hours
Change 2 days after, curing 5 days after pH such as table 1:
Table 1
Experiment two
Prepare 900g poultry excrement combustion ash (pH12.03) and 100g kind material respectively, adds the phosphoric acid of the amount of Table 1
Aqueous solution (phosphoric acid concentration 42.83%).It is ripe after curing 1 day after measurement mixing just stops and is warmed to 50 degree and cures 6 hours
Change 2 days after, curing 5 days after pH such as table 2:
| Phosphate aqueous solution (g) | Just stop | 6 hours | 1 day | 2 days | 5 days | |
| 2-1 | 65.0 | 5.61 | 5.90 | 6.02 | 5.96 | 5.93 |
| 2-2 | 82.5 | 5.28 | 5.70 | 5.74 | 5.66 | 5.65 |
| 2-3 | 90.0 | 4.72 | 5.60 | 5.63 | 5.60 | 5.50 |
| 2-4 | 100.0 | 4.54 | 4.95 | 5.32 | 5.41 | 5.39 |
Experiment three:
Addition 10kg kind material and phosphoric acid concentration 42.83% in the 90kg poultry excrement combustion ash (pH12.03)
Then phosphate aqueous solution is warmed to 48 degree, cure within 3 days, the phosphoric acid processed material of obtained poultry excrement combustion ash
PH is 5.60.
Test 1 fertilizer: the part phosphoric acid processed material extrusion molding that experiment three is obtained obtains diameter 3mm, length 4.5mm
1 fertilizer of test.
Test 2 fertilizer: the phosphoric acid processed material 30kg and sulphur of part poultry excrement combustion ash obtained in three being implemented
Sour ammonium 20kg is mixed to obtain chicken manure cooperation fertilizer 50kg, and the mixed processing object extrusion molding that will be obtained obtains diameter
2 fertilizer of test of 3mm, length 4.5mm.
Test 3 fertilizer: by the phosphoric acid processed material of part poultry excrement, 40kg rape oil slag obtained in 55kg embodiment three
The mixture extrusion molding for 5kg water, being mixed, and being obtained obtains diameter 3mm, 3 fertilizer of test of length 4.5mm.
Compare 1 fertilizer: ammonium sulfate.
It compares 2 fertilizer: replacing the phosphoric acid in experiment three using nitric acid, obtain nitric acid treatment object, part nitric acid treatment object squeezes
It shapes out, obtains diameter 3mm, 2 fertilizer of comparison of length 4.5mm.
Compare 3 fertilizer: untreated poultry excrement combustion ash.
Place the soil of same soil property respectively in Culture basin, and respectively apply isodose above-mentioned three kinds of tested fertilizers and
Three kinds of comparison fertilizer, sow 20 celery seeds respectively, and after planting the 8th day investigation germination percentage carries out maximum leaf length on the 18th day
Measurement carries out the long and maximum plant weight amount of maximum leaf on the 24th day and is measured to obtain the result of planting experiment 1-3 and plantation comparison 1-3
It is as shown in table 3:
Table 3
By above-mentioned table it is found that the germination percentage obtained using planting experiment 1-3, maximum leaf length, maximum on the 24th after 18 days
The weight of the long and maximum strain of leaf is more excellent than plantation comparison 1-3.Animal wastes are handled using waste phosphoric acid to obtain phosphoric acid processing
Object shows the effect of compost, keeps crop growth good, therefore reach the treatment of wastes with processes of wastes against one another, makes the mesh of ecological environment sustainable development
's.
