Abstract
The invention relates to a composite type polymeric flocculant which is mainly applied to the fields such as sewage treatment, sludge thickening, paper pulp recovery, petroleum extraction, etc. The composite type polymeric flocculant is characterized by being prepared by raw materials by weight percent: 40-45% of elm bark grass powder, 30-35% of cactus powder, 5-10% of sodium carboxymethyl cellulose and 15-20% of polyacrylamide. The flocculant can be normally used at higher temperature and under the condition of wider range of pH value.
Description
Technical field
The present invention relates to a kind of composite type polymeric flocculant, be mainly used in fields such as sewage disposal, mud concentrate, pulp recovery, oil production.
Background technology
High sub-flocculation agent belongs to the organic-flocculation category, and its primary categories has carboxymethyl class, acyl ammonium class, acrylic acid or the like; Using at present comparatively extensively is acyl ammonium class.Conventional flocculation agent is more than 50 ℃, and this product instability, performance can't guarantee and be only applicable to neutral environment, and in meta-acid or inclined to one side alkali condition, effect is had a greatly reduced quality.
Summary of the invention
The object of the present invention is to provide a kind of composite type polymeric flocculant, this flocculation agent can normally use under higher temperatures and alkaline condition.
To achieve these goals, technical scheme of the present invention is: composite type polymeric flocculant, it is characterized in that it is formed by elm leather and fur powder, cactus powder, Xylo-Mucine and polyacrylamide feedstock production, and the shared mass percent of each raw material is:
Elm leather and fur powder: 40%-45%;
Cactus powder: 30%-35%;
Xylo-Mucine: 5%-10%;
Polyacrylamide: 15%-20%.
The shared mass percent the best of each raw material is: elm leather and fur powder: 42%; Cactus powder: 32%; Xylo-Mucine: 8%; Polyacrylamide: 18%.
The present invention has following beneficial effect: composite type polymeric flocculant belongs to non-dangerous goods, nontoxic, non-corrosiveness, have water absorbability, have the efficient of organic polymer coargulator and the biodegradable characteristic of the scope of application and natural macromolecule flocculating agent widely simultaneously; Using in higher temperatures (about 80 ℃) and wider pH value scope has good result, has particularly added Xylo-Mucine, and this composite type polymeric flocculant uses under 80 ℃ of temperature, and its action effect is obvious; To the adaptive faculty that the pH value changes, (pH is 7-12) result of use is good under alkaline condition especially.
Description of drawings
Fig. 1 is preparation technology's schema of the present invention.
Embodiment
In order to understand the present invention better, further illustrate content of the present invention below in conjunction with embodiment, but content of the present invention not only is confined to the following examples.
Embodiment 1:
Composite type polymeric flocculant, it is formed by elm leather and fur powder, cactus powder, Xylo-Mucine and polyacrylamide feedstock production, and the shared mass percent of each raw material is: elm leather and fur powder: 42%; Cactus powder: 32%; Xylo-Mucine: 8%; Polyacrylamide: 18%.
The preparation method of above-mentioned composite type polymeric flocculant, as shown in Figure 1, it comprises the steps;
1) preparation of raw material: the elm leather and fur is dried the back pulverize, cross 50 purposes sieve then, dry again, obtain elm leather and fur powder; Root and stem of Cholla is dried the back pulverize, cross 50 purposes sieve then, dry again, obtain cactus powder; By the shared mass percent of each raw material be: elm leather and fur powder 42%, cactus powder 32%, Xylo-Mucine 8%, polyacrylamide 18%, choose elm leather and fur powder, cactus powder, Xylo-Mucine and polyacrylamide raw material for standby;
2) elm leather and fur powder, cactus powder, Xylo-Mucine and polyacrylamide are mixed, microwave copolymerization then, the condition of microwave copolymerization is: the microwave radiation frequency is 3-30GHz, power be 500W, time are 10-30min (minute), the microwave multipolymer; It is stable to carry out alkali after the microwave copolymerization: add the NaOH dissolving in the microwave multipolymer, adjusting pH is 10-12, and reaction 30-60min makes multipolymer carry out the H-Na exchange, promotes it to use under alkaline environment; Alkali is stablized after-filtration, drying, pulverizing, obtains composite type polymeric flocculant.
The test of composite type polymeric flocculant flocculating effect:
One), testing sequence
1, flocculation agent dilution: the composite type polymeric flocculant that takes by weighing the 5g present embodiment evenly adds in the clean tap water of 500mL, and the limit edged stirs fast, so that medicament disperses well, prevents conglomeration.
2, stir at a slow speed and make the intact dissolving of composite type polymeric flocculant half an hour, this moment, unsuitable stirring velocity was too fast, otherwise can interrupt molecular chain because of shearing action, reduced molecular weight.
3, the composite type polymeric flocculant after will diluting adds into pending waste water, and the composite type polymeric flocculant dosage is 1-2mg/L, stirs 15min at a slow speed and leaves standstill 30min then;
4, measure processing front and back waste water cod and ss, observe flocculation alumen ustum outward appearance simultaneously;
5, with repeating step 1-4 after one times of the flocculation agent dilution.
Two), experimental result
Through measuring, for paper plant's high temperature steaming waste water (80 ℃, pH be about 12 experiments):
When 1, concentration was 10mg/L, the cod clearance was about 60%, and the ss clearance is 85%, and the alumen ustum of flocculation is excessive.
When 2, concentration was 5mg/L, the cod clearance was about 65%, and the ss clearance is 95%, and the alumen ustum of flocculation is tight.
Because paper plant's boiling wastewater temperature is high and alkalescence is arranged, by simultaneous test, the flocculating effect under the 5mg/L condition is better, and its clearance is more than 95%.
Generally speaking, the effect of composite type polymeric flocculant of the present invention is better than conventional organic polymer coargulator; Remedied the deficiency of conventional organic polymer coargulator on the scope of application simultaneously.
Embodiment 2:
Composite type polymeric flocculant, it is formed by elm leather and fur powder, cactus powder, Xylo-Mucine and polyacrylamide feedstock production, and the shared mass percent of each raw material is: elm leather and fur powder: 40%; Cactus powder: 30%; Xylo-Mucine: 10%; Polyacrylamide: 20%.
The preparation method of above-mentioned composite type polymeric flocculant is substantially the same manner as Example 1, just the proportion of raw materials difference.
Embodiment 3:
Composite type polymeric flocculant, it is formed by elm leather and fur powder, cactus powder, Xylo-Mucine and polyacrylamide feedstock production, and the shared mass percent of each raw material is: elm leather and fur powder: 45%; Cactus powder: 35%; Xylo-Mucine: 5%; Polyacrylamide: 15%.
The preparation method of above-mentioned composite type polymeric flocculant is substantially the same manner as Example 1, just the proportion of raw materials difference.
