Abstract
A process for preparing composite flocculant containing natural organic and inorganic substances includes extracting liquid-state chitose from edible aquatic animals, extracting liquid-state alginic acid from edible aquatic plants, mixing them with liquid iron salt and aluminium salt at temp lower than 65 deg.C, and dewatering, and features simple process, high flocculating effect and no toxic by-effect of obtained flocculant used to purify water.
Description
The present invention relates to a kind of organic and inorganic composite flocculation agent and manufacture method thereof, be applicable to purify each class I liquid I, comprise that the waterworks drinks the processing of water purification and industrial and mining enterprises' waste water, its international Patent classificating number is C02F1/52-1/56; B01D021.
Along with industry, the especially development of chemical engineering industry, the deterioration and the contaminated water source of environment are on the rise, the processing of industrial waste water and drink that water purification has become more and more important and urgent, the research and development of carrying out the used flocculation agent of above-mentioned processing has caused the great attention of scientific and technical personnel and relevant department.
Existing flocculation agent is divided into inorganic flocculating agent, synthetic organic polymer flocculation agent and natural organic high-molecular flocculant three major types.
Inorganic flocculating agent, it mainly is the flocculation agent of making of aluminium salt, higher with aluminum content in its treated water, people often drink the higher water of aluminum content, human body will be taken in a large amount of aluminium and accumulate in cerebral tissue, memory fails gradually, has arrived old easy trouble senile dementia, directly the health and lives of harm humans; In addition, its flocculation process is subjected to the influence of temperature, water temperature bigger, winter flocculating effect poor, cause many difficulties for the water treatment manufacturing process.
The synthetic organic polymer flocculation agent, as polyacrylamide, its incomplete polymeric monomer has the intensive neurotoxicity in polymerization process, and has strong carinogenicity, the health that also endangers people.
Natural organic high-molecular flocculant mainly is the marine alga acids, and the costliness of its economic cost makes it lose practical value.
So people sound out the composite flocculation agent that exploitation organism and inorganics are composited, but because its organism is a synthetic, also have incomplete polymeric monomer in the building-up process, have strong carinogenicity; Its inorganics adopts simple aluminium salt, and so-called " alumen ustum wafts " phenomenon appears in alumen ustum and be difficult for precipitation, causes flocculating effect undesirable.Application number is 94104505.6, the applying date is on April 26th, 1994, just belongs to this kind situation for " manufacture craft of the organic and inorganic composite highly effective water purification agent " patent in November 1 nineteen ninety-five in open day.
Purpose of the present invention is exactly in order to overcome the shortcoming of above-mentioned flocculation agent, to develop a kind of new and effective natural organic and inorganic composite flocculant.
The object of the present invention is achieved like this: adopt edible natural with the liquid chitose that extracts in the animal of Haihe River and from edible natural with the liquid seaweed acids that extracts the plant of Haihe River as the natural organic high-molecular composition, adopt liquid aluminium salt and molysite as inorganic composition simultaneously, utilize inorganic flocculating agent to compare with inorganic flocculating agent with the composite flocculation agent that synergistic effect is made with the bridge formation of natural organic high-molecular, can make that aluminum content drops to 1/50 in the water, greatly got rid of the toxic side effect of aluminium, the health that is beneficial to man to people's cranial nerve; It makes the influence that is not subjected to temperature, water temperature simultaneously, is convenient to manufacture.Because the present invention does not contain the synthetic organic high molecular compound, just do not exist again because of of the threat of the incomplete toxicity monomer that produces of artificial polymerization to human health.Though also adopted expensive natural polymer organism among the present invention, consumption is less, and the flocculating effect that produces improves more than three times than existing flocculation agent, and its manufacturing cost is reduced, and has the characteristics of practicality, economy.In addition, because aluminium salt, molysite exist simultaneously among the present invention, its proportion is increased, settling velocity is fast, and flocculating effect is remarkable.
Now the present invention is described in detail in conjunction with an embodiment:
At first prepare natural organic matter, its composition and ratio are:
Liquid chitose 60～85%
Liquid seaweed acid 15～40%
Technology: mix temperature≤65 ℃
Prepare inorganics then, its composition and ratio are:
Liquid molysite 10～90%
Liquid aluminium salt 10～90%
Technology: mix at normal temperatures
At last the natural organic matter and the inorganics of above preparation are pressed following mixed:
Natural organic matter 5～30%
Inorganics 70～95%
Technology: mix temperature≤65 ℃
The product that aforesaid method is made is for liquid, also can make solid-stately as required, and liquid product dewater under≤65 ℃ of processing condition afterwards.
Manufacture craft of the present invention is simple; cost is low; flocculating effect is good; the water purification ability is more than three times of common flocculation agent; and have no side effect; the health that is beneficial to man and environment protection are applicable to the purifying treatment of each class I liquid Is such as drinking water purification and trade effluent to be higher than 65 ℃ of high temperature but avoid in storage, transportation and use.
