Abstract
The present invention relates to compound chlorine aluminum iron, particularly to a high-efficiency water treating agent which is prepared from 5 to 9% of sulfuric acid, 34 to 35% of hydrochloric acid and 10 to 11% of ferrite stone through stirring, polymerization, thermalization, precipitation, drying, packaging, etc. The present invention has the advantages of simple and convenient process and operation, and integral functions of high efficiency, high speed, low consumption, nontoxicity and high safety; the present invention can be widely used for purifying and treating domestic sewage, industrial water and various kinds of waste water and sewage.
Description
Technical field
The present invention relates to the preparation method that a kind of water conditioner is the compound aluminium-iron polychloro water purification agent.
Background technology
At present, be used for the product of water treatment on the market, decontamination effect improving is all not remarkable, for example: Tai-Ace S 150, labour intensity is big, and corrodibility is big, influential to the pH value of water, the water producing cost height, the water-insoluble behind the water purification is many; Aluminium chlorohydroxide to the high turbidity of high temperature, low temperature and low turbidity water, is difficult to adapt to.
Summary of the invention
The purpose of this invention is to provide that a kind of manufacture craft is simple, labour intensity is little when using, the preparation method of efficient, nontoxic, safe compound aluminium-iron polychloro water purification agent.
The present invention realizes by following technical proposal: the preparation method of compound aluminium-iron polychloro water purification agent comprises batching, stirring, polymerization slaking, precipitation, oven dry, metering packing:
(1) ferrous sulfate of the hydrochloric acid of the sulfuric acid of 5-9%, 34-35%, 10-11%, 21% three werthemanite soil and hot water are dropped in the reactor stir by weight ratio;
(2) material of gained is put into agitated pool and constantly stir, when stirring, add successively by weight ratio and carry out neutralization reaction for the calcium aluminate powder of 25-28%;
(3) the material input aerobic fermentation tank with gained carries out slaking;
(4) slaking is good material is put into the clarification of settling tank precipitation;
(5) will clarify material input header tank stores;
(6) will clarify material and promptly make finished product compound aluminium-iron polychloro water purification agent by header tank input drying machine drying, metering, packaging final prod at last, its chemical molecular formula is: [Al

Description of drawings
Accompanying drawing is a process flow diagram of the present invention.
The present invention selects the fine calcium aluminate powder for use, and ferrous sulfate, three werthemanites soil are main raw material, and collection aluminium salt system and molysite are the advantage what one of two kinds of water conditioners.Utilize polymeric aluminum and high molecular polymerization iron multipolymer, introduce an amount of synergistic agent SO in it
4Ion forms a kind of new and effective water purification agent of being made up of the inorganic polymer polymeric ferric aluminum.Outward appearance of the present invention is golden yellow crystallization sheet or powder.This product is diluted by a certain percentage according to needs, and liquid product concentration must not be less than 3%, and solids concn must not be less than 1%.Liquid after the dilution is answered and was used up in 72 hours.Ingredient proportion should be decided according to the source water quality face, can do water test earlier, to determine best dosage.Between the general source water turbidity 10-50,1000 tons of water can be thrown 2-5 kilogram water purification agent, by that analogy.Purify charging capacity and be generally 9-30PPM (1,000,000/).After the present invention drops in the water in right amount, can finish electrification fast, flocculation, the adsorption precipitation materializing procedure, thus reach the effect that purifies water effectively.
The present invention compares with other like product, and its advantage is: 1. manufacture craft is simple, cost Low; 2. genus inorganic high molecular composite water purifying agent, structure is expanded, absorption affinity is strong; 3. input source Floccule body forms soon behind the water, and the degree of polymerization is big, and active high, filterability is good; 4. the adaptation of product is strong, Applied range does not have impact to the pH value of water, and purifying water effect is remarkable; 5. have denitrogenating, go out The miscellaneous functions such as algae, sterilization, sterilization; 6. non-corrosiveness is simple to operation, water producing cost Low, the water quality after the purification is pure clear.
The present invention can be widely used in Drinking Water and water for industrial use and papermaking, printing and dyeing, metallurgy, send out The purified treatment of the various waste water such as electricity, chemical industry, leather, hospital, sewage also can be used for various lives The purified treatment of sewage.
