Abstract
The invention provides a waste water treatment medicament, which belongs to the waste water treatment technical field. The waste water treatment medicament contains Al<3+>, Fe<3+>, Mg<2+>, a few Mn<2+> and lithopone, wherein the content percentages are 30-40% of Al<3+>, 20-30% of Fe<3+>, 30-40% of Mg<2+>, a few Mn<2+> and lithopone. The waste water treatment medicament uses a general method for mixing and preparing, the method comprises the following steps: weighting a certain amount of water, adding aluminum sulfate, iron sulfate, magnesium sulfate, manganese sulfate and lithopone according to the above ratio, uniformly stirring at room temperature, completely dissolving to obtain the product. The invention has the advantages of wide usage scope, high deposition rate, good water quality, low treatment cost, no corrosion effect on steel structure, no toxicity, no pollution, safe usage and the like. The waste water treatment medicament can be applied to various waste water treatment in oil field, coal mine, textile mill, dyeing plant and the like, and can be applied to city sewage treatment.
Description
Technical fieldThe invention belongs to technical field of waste water processing, mainly relate to a kind of wastewater treatment medicament.
Background technologyChemical precipitation method extensively is used in WWT; It is in waste water, add some chemical agent make it with waste water in pollutent generation chemical reaction; Form the solid resultant of indissoluble, carry out solid-liquid separation then, thereby remove a kind of method of water pollutant.At present in some industries, like the medicament that black water, oil-containing wastewater, dyeing waste water, paper waste etc. are adopted, poor processing effect, settling velocity are slow, and medicament expense is higher, and some enterprise also causes the equipment heavy corrosion.
The colliery produces a large amount of black waters aborning, will cause severe contamination as these water in time not being handled.Existing black water treatment process adopts adding medicine to handle more, polyaddition aluminum chloride or calcium chloride and SEPIGEL 305 coupling in black water, and deposition is administered.Owing to introduced cl ions in a large number, thereby caused the equipment heavy corrosion.
Oil recovery factory, oil field recovered water is to come out from reservoir exploitation with crude oil, not only carries crude oil in the waste water, in the oil reservoir of HTHP, has also flow to various salts and the gas in the stratum; In oil recovery process; From the stratum, carry out many suspended solidss again, therefore, the characteristics of oil field extracted water are that not only COD and oil-contg are high; And temperature is high, and salinity is high.Now dosing sedimentation and filtration methods that adopt are handled more, and mostly dosing is polymeric aluminum, and the ubiquity problem is that treatment effect is bad.
Summary of the inventionThe present invention has used chemicals treatment weak effect in the wastewater treatment now in order to solve exactly, settling velocity is slow, cost is high, and problems such as equipment heavy corrosion provide a kind of high-level efficiency, low cost, the avirulent wastewater treatment medicament of wide, the no burn into of adaptation.
Wastewater treatment medicament of the present invention is Al-Fe-Mg compound, wherein Al
3+Account for 30～40%, Fe
3+Account for 20～30%, Mg
2+Account for 30～40%, also have a spot of Mn
2+And lithopone, Mn

3] add; Mg
2+Can use sal epsom (MgSO
4) add; Lithopone is the mixture of zinc sulphide and permanent white, and molecular formula is: ZnS+BaS0
4, ratio is 3:7.
Compound method is to adopt the general method uniform mixing to form.(about 15 minutes) the whole dissolvings that at room temperature stir can be used.Use temperature is at 5 ℃～50 ℃.
The ultimate principle that the present invention disposes of sewage is that the colloid in the sewage is destroyed.Contain a large amount of suspended substances, emulsification etc. in the sewage and be the colloidal state existence.Use medicament of the present invention to fall colloid surface charge neutralization in the sewage, thereby destroy colloidal suspended substance and emulsification etc., make the suspended substance rapid precipitation.
The present invention has following advantage:
1, use range is wide, and sedimentation effect is good, and effluent quality is good, and processing cost is low
This wastewater treatment medicament is applicable to black water, oily(waste)water, dyeing waste water, paper waste, chemical industry and municipal effluent etc.After adding this medicament in the sewage, suspended substance flocculates at once, and the alumen ustum of generation is big, and deposition is quick, and efficient is high, and floc sedimentation intensity is high, and hydrophobic performance is good, is beneficial to press filtration.The filter cake after pressure filtration water ratio is low, and quality is good.The medicament expense of handling every cube of this medicament of sewage is merely about 60 percent of other medicament expenses.
2, non-corrosiveness
The pH value of solution is similar to neutrality 6.5～8.5 after this chemicals treatment, does not contain Cl
-Ion after the treating water reuse, can be protected the steelwork in the aqueous systems effectively, makes its corrosion, therefore can reduce a large amount of equipment maintenance costs every year.
3, nontoxicity
This wastewater treatment medicament purity height, inclusion-free, no dust, the aqueous solution is as clear as crystal.This medicament nontoxicity does not have influence to the operator, handles problems such as back water non-secondary pollution.
Embodiment
Add Tai-Ace S 150 40g (purity is more than 95%) ferric sulfate (purity is more than 95%) 20g according to 1L water; Sal epsom (purity is more than 95%) 30g, manganous sulfate (purity is more than 95%) 5g, lithopone (more than 90%) 5g; Adopt steel body, the anticorrosion dispensing canister of glass reinforced plastic to prepare wastewater treatment medicament of the present invention; The 8m of dispensing canister diameter Ф=1., high h=2.0m, volume V=5.1m
3, the drug concentration of preparation is 2.6%.
EXAMPLE l is carried out Processing Test with top wastewater treatment medicament to pit coal muddy water, and this black water is the middle part water in the Ф 24m of the coal separating plant rake formula concentration basin.Black water is squeezed in the Ф 8m thickner, in the pipeline of squeezing into, added wastewater treatment medicament of the present invention, the black water after the dosing precipitates in by the 8m concentration basin.The post precipitation supernatant overflows to clean water basin, is back to coal washing.The post precipitation flocs unit is got to belt filter press with surge pump and is dewatered.Test adopts the 4Ps water pump to beat black water, and flow is 70m
3/ h, adding treatment agent dominant discharge of the present invention is 0.7-0. 8m
