Description
Technical field
The invention belongs to flocculant and its preparing technical fields, and in particular to it is a kind of reduce waste water hardness HT2 efficiently wad a quilt with cotton
Solidifying agent and preparation method thereof.
Background technology
In the processing of industry water, drinking water and sanitary sewage, the performance of HT2 flocculants is most important.The wadding of water process
Solidifying process is by nanoscale, micron-sized suspended substance or colloidal impurity particle in water under the action of HT2 flocculants, by solidifying
Poly-, i.e. flocculation reaction forms big floc particle, is finally removed it by the techniques such as precipitating, filtering.In recent years, coagulant develops
Rapidly, interaction after different flocculants is compound, it can be achieved that have complementary advantages, overcome the single flocculant scope of application of tradition compared with
Narrow disadvantage, to improve flocculating effect.
For the mechanism and technical process of flocculation, people have carried out a large amount of in-depth studies, experienced three mainly
Developing stage：1, before the sixties in last century, the theory of flocculation studied based on physical theory, such as according to classical colloid chemistry
It theoretical Gwoy-Chapman double ionic-layer theories and the DLVO cohesion physical theories established and is proposed by Si Moluhuo Paderewskis
Flocculation rate gradient theory.Flocculation mechanism mainly emphasizes the diffusion layer of compressed particle electric double layer, reduces or eliminates potential energy barrier
Cohesion mechanism and laminar velocity gradient decide intergranular collision flocculation.2, it after the sixties in last century, grinds
Study carefully flocculated microphysics chemical action mechanism and emphasize that the theory of microphysics chemical process proposes in succession, such as charge neutrality/suction
Attached cohesion, adsorption bridging is theoretical and micro-vortex In The Coagulation Dynamics are theoretical, these theories highlight the change in cohesion flocculation process
The contribution that effect and water turbulence micro-vortex combine coagulated particles collision.3, after the eighties in last century, flocculating polymer
Agent and its research of theory are greatly developed, according to absorption/charge neutrality theory and Surface complex formation model, it is proposed that " cover on surface
Lid " flocculation pattern.
HT2 flocculants still have a series of problems such as poor product stability, impurity iron content height, poorly water-soluble at present,
Urgent need is improved its formula and processing technology, and then realizes the efficient stable production of HT2 flocculants, reaches international and first intakes
It is flat.
Invention content
The purpose of the present invention is that existing HT2 flocculant products stability is poor, impurity iron content is high, water-soluble in order to solve
Property difference problem, provide it is a kind of reduce waste water hardness HT2 efficient flocculants and preparation method thereof.
To achieve the above object, the technical solution adopted by the present invention is as follows：
A kind of HT2 efficient flocculants reducing waste water hardness, the flocculant is according to mass fraction by 1.5 parts of sodium hydroxides, 1
The additive B composition of part aluminium hydroxide, the additive A of all hydroxide quality 0.2%, all hydroxide quality 0.1%；Institute
The additive A stated is glucose；The additive B is cellulose.
A kind of preparation method of the efficient flocculant of above-mentioned reduction waste water hardness, the preparation method are specially：
Sodium hydroxide and aluminium hydroxide are added in normal-pressure reaction kettle, increases temperature to 90 DEG C, additive A, heat preservation 8 is added after keeping the temperature 2 h
Additive B is added after h, continues to keep the temperature after 10 h to get to efficient flocculant.
The advantageous effect of the present invention compared with the existing technology is：
（1）The present invention realizes the stability production of HT2 flocculants, solves stability in traditional HT2 flocculants synthesis technology
The problem of difference, impurity iron content height, poorly water-soluble.
（2）By being optimized to the existing synthesis technology of HT2 flocculants, synthetic ratio reaches 99.9%, and production cost reduces
30%。
（3）In the present invention one was increased to by one month by the use of additive A and additive B, HT2 flocculant stability
Year or more, product quality meets company standard.
（4）After the present invention is applied to production, the quality of HT2 flocculant products is substantially increased, production capacity reaches 50,000
Ton/year, push the promotion of HT2 flocculant industry overall technology levels.
（5）The present invention improves product quality, reduces environmental risk, and significantly reduces production cost, the HT2
Flocculant can be applied in water process, and the water process is handled waste water such as coal chemical industries.
（6）The present invention can reduce the turbidity and hardness of sewage, remove suspended matter, so that it is generated the condensate of bulky grain, add
The speed of fast impurities in water and sludge settling.
