Description
Technical field
The invention belongs to city water, sanitary sewage, field of industrial waste water treatment, particularly relate to a kind of organic and inorganic compound
Mould assembly efficient flocculant and preparation method thereof.
Background technology
Along with the high speed development of China's modernization of industry process, how to improve the efficiency of water for industrial use, save valuable water
Resource, and in the sustainable development of rational development of water resources application and water resource utilizes, water technology plays not
Alternative important function.For source water, the purified treatment of feedwater, sanitary sewage, industrial wastewater recycling in, flocculant
(comprise some and have the coagulant of agglutination, flocculation aid) is chemistry in water treatment medicament the most frequently used in water processing links, they
It is broadly divided into organic polymer coargulator and the big class of inorganic polymer flocculant two.
China's inorganic flocculating agent applicating history is long, owing to low-molecular inorganic flocculant exists bigger in water treatment procedure
Problem, progressively substituted by inorganic polymer flocculant, it is more effective than original flocculant much, and price the most corresponding
As, thus progressively become the main flow medicament that same organic polymer coargulator is the same.But, no matter it is used alone that a kind of organic high
One's share of expenses for a joint undertaking flocculant or inorganic polymer flocculant, have respective limitation, has respective pluses and minuses: 1. organic polymer
Flocculant shows: building bridge for Organic substance float, it is excellent to adsorb, and flocculates excellent, and coagulation grain group is big, and formation speed is fast, sedimentation filtration
Good, the pH value that applicable scope is bigger.But in operation condition and the time of hydrolysis, stability, show themselves in that hydrolysis time is long,
Diluent keeping quality after hydrolysis, poor stability, must avoid during operation at a high speed and stirring of overrunning, except chromatic effect and clarity
Poor.2. inorganic polymer flocculant shows: have preferable coagulation flocculating effect for inorganic matter, for the glue in float
Body thing is extremely effective, and particularly when high concentrtion, performance is notable.Clarity is extremely effective, preferably removes lignin, humus etc.
Color, hydrolysis time is short, the advantage that after hydrolysis, the diluent holding time is longer.But flocculate in operation condition formation condition
Poor, do not have organic polymer coargulator excellent.Because sedimentation filtration speed is general, at a high speed after answer low rate mixing, adsorption activity is poor,
Flocculating strength is the most weak, alumen ustum easily by Work machine strength failure, the shortcoming that the pH range of adaptation is less.
In each side such as Water purification, sanitary sewage disposal, Industrial Wastewater Treatment, valuable substance recovery and sludge treatments
When face uses flocculant, it is contemplated that the kind of float, electric charge, chemical substance composition in handled water quality, surface activity
The pH value of architectural characteristic, granularity, concentration and water quality, temperature, the chemical composition of concurrent, process technique, equipment etc. and select
Select.Perhaps two kinds of flocculant compound with better adapting to the process of different quality, organic and inorganic two kinds of macromolecules
When flocculant is used in combination, its major advantage being added effect is: 1. guarantees that 2. clarity increase the intensity of flocculation, strengthens grain
3. degree and adsorption activity improve concentrations, filter and the efficiency of lock out operation 4. accelerate to flocculate formed, precipitate, the speed of the process such as filtration
Degree, simplifies technological process, and 5. the disposal ability that improve process equipment structures improves the compressibility of mud, dehydration property,
6. minimizing subsidence volumn expands the scope of effective pH value that flocculates and 7. saves processing cost, medicament expense use.
Although the most domestic research for inorganic composite floculant and patent, disclose much new technique,
But their technique is all to hydrolyze, with inorganic flocculating agent, the use that is combined with each other by organic flocculant and hydrolysis, or will be each
Multi-point adding after organic flocculant is compound and after the hydrolysis dilution of inorganic flocculating agent.These inorganic composite floculants are at mesh
Still there is many drawbacks in front water treatment procedure, medicament movement requirement height, complex process, equipment investment greatly, process and take up an area
Area is big, and operational management is complicated, and operating cost is high, it is impossible to adapt to the application of the many new water treatment facilities developed under the new situation,
Cause the limitation processing market application at water.
Summary of the invention
The present invention is to solve inorganic composite floculant needs the technical problem that hydrolysis dilution adds in water processes,
A kind of flocculant added without hydrolysis dilution, a kind of height that organic-inorganic flocculant is effectively combined into a kind of broad spectrum type are provided
Effect, the powder flocculant of rapid flocculation.Process for water provide one can simple and quick formation than great, sedimentation is fast, wadding thing is thick
Real flocculant.For this technique that water is processed, equipment, engineering, regulating tank, the scale of precipitate and separate groove can be reduced,
Reduce technological process, reduce construction costs, and can directly use integration to separate precipitation apparatus.Deduct common high score
Sub-flocculant etc. are various helps solidifying medicament to hydrolyze, through first, the method that dilution adds respectively, has simplified operation complexity, has managed loaded down with trivial details
Engineer operation.It is an object of the invention to provide a kind of economical, efficient, quick, broad spectrum type, energy industrialized production, without " three
Useless " pollute, environmentally friendly, be harmful to human health, realize garbage recycling, to reach the environmental friendliness of the treatment of wastes with processes of wastes against one another
The organic-inorganic composite flocculant of type.
