Description

A kind of water purification agent and preparation method thereof

Technical field

The present invention relates to technical field of water purification, and in particular to a kind of water purification agent and preparation method thereof.

Background technology

Nowadays, because population constantly increases, economy is developed rapidly, and people have excessively exploitation and unreasonable profit to resource Phenomenon, the Nature can also derive a series of problem, and these problems directly threaten our offspring, wherein pollution problem It is the most serious, and ought be wherein with water pollution problems head.

Ammonia nitrogen, organic matter and various content of beary metal increase during water resource pollution is mainly shown as water, and nutrient laden process adds Hurry up, algae infestation, cause water hypoxia, nigrescence, smelly.Further nitrification turns into ammonia nitrogen in the presence of nitrosation bacillus in water NO2 -And NO3 -, it all has certain toxic action to human internal organ and nervous system.Generally, contaminated water body often goes out Existing muddy, peculiar smell, sense organ is uncomfortable, the sense of taste is bad, has a strong impact on the application that people drank and lived production.

When being purified to water, commonly used water purification agent has aluminium polychloride, PAFC, alkali formula to prior art Aluminium chloride, polyacrylamide, ferrous sulfate, aluminum sulfate, bodied ferric sulfate, these cleansers are chemical scavengerses, deliver into In water can and water in other impurity it is aitiogenic so as to water purification, small part cleanser can be dissolved into water during water purification, Body can all be impacted using the water can be eaten, although and general activated carbon, alum and zeolite will not dissolve, it Simply physical absorption, purifying water effect is poor.

The content of the invention

The invention is intended to provide a kind of water purification agent, the physics water purification agent purifying water effect for having solved prior art is poor, and chemical The problem that water purification agent can dissolve again.

The technical scheme is that:A kind of water purification agent, including following raw material, the Chinese medicine dregs of a decoction, activated carbon, diatomite, Bentonite, sodium metasilicate, aluminum sulfate, white portland cement and gypsum, the parts by weight of each raw material are 30 ~ 50 parts of the Chinese medicine dregs of a decoction, 15 ~ 30 parts of activated carbon, 15 ~ 20 parts of diatomite, 5 ~ 10 parts of bentonite, 5 ~ 10 parts of sodium metasilicate, 15 ~ 20 parts of aluminum sulfate, white portland 3 ~ 5 parts of 5 ~ 10 parts of cement and gypsum.

Used as the further preferred of scheme, the parts by weight of each raw material are 30 parts of the Chinese medicine dregs of a decoction, 15 parts of activated carbon, diatom 3 parts of 15 parts of soil, 5 parts of bentonite, 5 parts of sodium metasilicate, 15 parts of aluminum sulfate, 5 parts of white portland cement and gypsum.

Another step as scheme is preferred, and the parts by weight of each raw material are 50 parts of the Chinese medicine dregs of a decoction, 30 parts of activated carbon, diatom 5 parts of 20 parts of soil, 10 parts of bentonite, 10 parts of sodium metasilicate, 20 parts of aluminum sulfate, 10 parts of white portland cement and gypsum.

Operation principle of the invention and beneficial effect:Water purification agent of the invention by the Chinese medicine dregs of a decoction, activated carbon, diatomite, Bentonite, sodium metasilicate, aluminum sulfate, white portland cement and gypsum are prepared from, containing abundant organic matter wherein in Chinese medicine, Contain a large amount of natural high molecular substances in organic matter again, such as polysaccharide fiber, this kind of material has certain to the pollutant in water Flocculation and suction-operated, while having abundant trace element and amino acid in the Chinese medicine dregs of a decoction, are more beneficial for people's supplement each Trace element and nutriment are planted, activated carbon is a kind of stereoplasm carbide of multiple aperture, and its adsorption capacity is very strong, the rate of filtration Hurry up, with decolouring, deodorant and cation exchange capacity (CEC), but the cation exchange capacity (CEC) of activated carbon is limited, to the ammonia nitrogen in water quality There is no removal ability.The present invention utilizes activated carbon, diatomite, bentonite, four kinds of material for water treatment of different structure of Chinese medicine dreg, Connected by the epoxy glue of water curable type adhesive gypsum and white portland cement, again molding, granulating, form a kind of purifying agent. Water purification agent low cost of the invention, it is easy to use, the ability that purifies water than individual event solid absorbent comprehensively, effectively, except color, remove The aspect effects such as taste, absorption ammonia nitrogen ability are protruded, while the water purification agent compression strength is big, water resistance is strong, are difficult to crush, and also will not Dissolving, can for a long time be dipped in water and play effect.

The preparation method of water purification agent, comprises the following steps, and step one, gets the raw materials ready:The Chinese medicine dregs of a decoction are ground into 100 ~ 200 purposes Particle, activated carbon powder is broken into the particle of 6 ~ 100 mesh, diatomite, bentonite, sodium metasilicate, aluminum sulfate, white portland cement and gypsum For powdered;

Step 2, mixing:By the Chinese medicine dregs of a decoction, activated carbon, diatomite, bentonite, sodium metasilicate, aluminum sulfate, white portland cement Mix after being weighed by weight with gypsum, add the water of gross weight number 15 ~ 20%, be again stirring for obtaining mixture;

Step 3, granulation:Mixture is placed in molding, granulating in pellet press, the particle of 30 ~ 50mm of particle diameter is made, will be made Particle dry 72h naturally after, then be placed into regulation drying temperature in drying chamber and, to 150 ~ 250 DEG C, water purification obtained final product after drying 4h Agent.

Preparation method of the invention, by 8 kinds of raw material scientific matchings, add water stirring after mixing according to required specification, granulation In the drying of drying case high temperature after drying under field conditions (factors) afterwards, graininess water purification agent compression strength is obtained greatly, water resistance is strong, Can for a long time be dipped in water and play effect.

Further, the Chinese medicine dregs of a decoction are the dregs of a decoction discarded after the Chinese medicine rich in polysaccharide fiber is processed.Polysaccharide fiber The flocculation ability of water purification agent can be improved.

Further, the Chinese medicine is ratio of rhizome medicinal material.The polysaccharide fiber contained in ratio of rhizome medicinal material is more.

Further, the ratio of rhizome medicinal material is Radix Codonopsis.Class containing polysaccharide fiber, phenols, sterol, volatile oil, dimension life in Radix Codonopsis Plain B1, B2, various necessary amino acid of human body, scutellarein glucosid, saponin and Alkaloid, trace element etc., are made Water purification agent there is coacervation excellent effect, speed fast, environment-protecting asepsis, low cost, applied widely.Its decolourize, it is deodorant, Remove ammonia nitrogen in water removal(NH4-N), COD and other effects significantly, can be used for various engineering of water treatment, culture fishery and drinking-water machine filter Core, can meet the related needs of people's daily life water purification and life production.
