Abstract

The invention discloses a purifying agent for water treatment. The purifying agent comprises, by mass, 60%-99% of aluminium polychlorid, 10%-20% of polymerization ferrrc chloride, 0.3%-10% of polypropylene titanium amine, 0.2%-20% of magnesium chloride and 0.0001%-1% of fluorescent whitening agents. A method for preparing the purifying agent includes mixing the aluminium polychlorid, polymerization ferrrc chloride, polypropylene titanium amine and magnesium chloride, adding the fluorescent whitening agents, uniformly mixing until raw materials are granular, and performing multi-weight package. The purifying agent for the water treatment has the advantages of being simple in process, short in time, small in use dosage, capable of purifying water quality, easy to decompose and free of residual toxicity and secondary pollution and the like.

Description

A kind of water treatment water purification agent

Technical field

The present invention relates to water treatment field, especially design a kind of water treatment water purification agent.

Background technology

Be accompanied by rapid development of economy, the pollution of water resources is on the rise, and the water sources such as lake, various places, river and underground water all are subject to pollution in various degree.On the one hand, the many town and country of China all face the problem of water quality lack of water, the practical problems that traditional water supply process that follow present waterworks and water supply network itself exist, cause the water quality of city tap-water further to improve very difficult, do not reach the standard of directly drinking, and urban and rural residents are more and more higher to the water quality requirement of domestic water.On the other hand, under the emergency situation such as some disasters, accident or wilderness lore, some water sources are not directly drunk, how under various complex environments, particularly in emergency circumstances realize purification of water quality, replenish easily body water, be the problem that people study always.In order to address the above problem, all kinds of water purification products arise at the historic moment.All kinds of water purification products have been developed and have produced both at home and abroad, generally speaking, its material for core is generally selected one or more active materials such as granular carbon, molecular sieve, directly be contained in these materials in the water purifier, although doing like this can removal heavy metal, agricultural chemicals, organism, can not effective sterilizing.Because bacterium can enrichment breeding on this class sorbing material.In order to sterilize, need to ooze silver or chlorination to gac, add iodinate, can bring secondary pollution like this, and complex process.And if add the dress porous ceramic filter element in the water purifier or through the porous polymer materials of sintering, hollow fiber filter membrane etc. are although can intercept the part bacterium, effective objectionable impuritiess such as removal heavy metal, agricultural chemicals, organism.Some filter core is taked multiple-stage treatment, uses multiple material remedying the defective of aforementioned filter core, but the complex structure of this filter core, price is high.In a word, the structural filter element of using in the existing treating processes of purifying waste water is unsatisfactory.

Summary of the invention

The object of the present invention is to provide a kind of water treatment water purification agent (flocculation agent), technique is simple, purifying water effect good, action time is short, consumption is few, reduce the hydrolysis content of aluminium salt in water body, thereby the potentially dangerous of having avoided aluminium salt to put aside in human body, well have reached the purpose of removing suspended solids, organism, algae purification water quality.And can effectively remove suspended solids, COD, BOD ₅, total nitrogen, total phosphorus, reduce the harmful organic substance inorganics, reached the purpose that middle water reuse, various sewage disposal reach discharging, improve water body environment.

Technical scheme of the present invention is: described a kind of water treatment water purification agent is by polymerize aluminum chloride, poly-ferric chloride, polyacrylamide, polyacrylamide, magnesium chloride, and white dyes etc. form.

Described a kind of water treatment water purification agent is characterized in that: polymerize aluminum chloride 60%-99%, and poly-ferric chloride 10%-20%, polypropylene titanium amine 0.3%-10% adds white dyes 0.0001%-1% after magnesium chloride 0.2%-20% mixes.

Preparation method of the present invention is: with polymerize aluminum chloride, poly-ferric chloride, polypropylene phthalein amine, magnesium chloride, add in proportion recombiner, and formulated.

Advantage of the present invention is: technique is simple, purifying water effect good, action time is short, consumption is few, reduce the hydrolysis content of aluminium salt in water body, thereby the potentially dangerous of having avoided aluminium salt to put aside in human body, well have reached the purpose of removing suspended solids, organism, algae purification water quality.And can effectively remove suspended solids, COD, BOD ₅, total nitrogen, total phosphorus, reduce the harmful organic substance inorganics, reached middle water reuse, various sewage disposal reaches discharging, improves water body environment.

Embodiment

Example 1 polymerize aluminum chloride 50%, poly-ferric chloride 10%, polypropylene phthalein amine 10%, magnesium chloride 18%, propylene phthalein amine 15%, mix rear adding white dyes 2%, churning time mixed rear adding white dyes 3% in 30 minutes at normal temperatures, stirred at normal temperatures 50 minutes, granulation shape thing, after carry out polynary weight packing, under different situations, be added in proportion the mechanism of action in the water body.

Example 2 polymerize aluminum chlorides 89%, poly-ferric chloride 1.1%, polypropylene phthalein amine 0.9%, magnesium chloride 4%, propylene phthalein amine 3%, mix rear adding white dyes 2%, churning time mixed rear adding white dyes 1% in 40 minutes at normal temperatures, stirred at normal temperatures 50 minutes, granulation shape thing, after carry out polynary weight packing, under different situations, be added in proportion the mechanism of action in the water body.

Example 3 polymerize aluminum chlorides 80%, poly-ferric chloride 3%, polypropylene phthalein amine 2%, magnesium chloride 5%, propylene phthalein amine 7%, mix rear adding white dyes 2%, churning time mixed rear adding white dyes 1% in 20 minutes at normal temperatures, stirred at normal temperatures 60 minutes, granulation shape thing, after carry out polynary weight packing, under different situations, be added in proportion the mechanism of action in the water body.

Claims

1. water treatment water purification agent, it is characterized in that: described water purification agent is by polymerize aluminum chloride, poly-ferric chloride, polyacrylamide, polyacrylamide, magnesium chloride, white dyess etc. form.

2. a kind of water treatment water purification agent according to claim 1, it is characterized in that: polymerize aluminum chloride 60%-99%, poly-ferric chloride 10%-20%, polypropylene titanium amine 0.3%-10% adds white dyes 0.0001%-1% after magnesium chloride 0.2%-20% mixes.
