Description
Technical field
The present invention relates to sewage treatment area, and in particular to use in waste water treatment coagulant and preparation method thereof.
Background technology
Particle in sludge is mainly colloidal solid, and the colloidal solid has extremely complex structure, the adhesion with water
It is very strong, so it is difficult to being separated with water.It is generally necessary to add coagulant, colloidal solid is set to reunite together, colloidal solid increases
After big, specific surface area reduces, and the water capacity of its adsorption easily departs from from colloidal solid.Although conventional coagulant can improve
Dewatering efficiency, but to CODcr, colourity, total CN-Clearance etc. main contamination index is not high.
The content of the invention
For above-mentioned technical problem, present invention offer is a kind of can both to play coagulation dehydration, can also remove CODcr、
Colourity, total CN-The FZC coagulant for treating sewage of material, specific technical scheme are：
Use in waste water treatment coagulant, including following material is by weight, 28~32 parts of frerrous chloride, aluminum sulfate

23~27 parts of powder.
The preparation method of use in waste water treatment coagulant, comprises the following steps：
(1) ethyl polysilicate and polyamide are charged first in container, are added alcohol solvent dissolving, are heated with stirring to 50~60
DEG C, heating and continuous 30~40 minutes；Wherein, an inventive point of the invention is：Ethanol can be replaced with ethanol and ethylene glycol
According to weight ratio 1：(0.5-2) is allocated, and the product after allotment has higher stability and product quality.
(2) other raw materials mix by weight ratio, are crushed to 50~100 mesh；2~3h is stirred under the conditions of 85~90 DEG C；
(3) keeping temperature, in the raw material in step (2) plus water stirs, and the raw material that every 100 parts of weight adds weight and is
40~50 parts of water, then the Ca (OH) that mass concentration is 5~8% is added dropwise2Emulsion, the raw material that every 100 parts of weight add Ca (OH)2
Weight be 0.1~0.5 part；Continue stirring after being added dropwise 1~1.5 hour；
(4) by material obtained by step (1) and material mixing obtained by step (3), stir；
(5) after the mixture of step (4) being cooled into room temperature, then dried, sieved, obtain use in waste water treatment coagulant
Powder-type finished product.
Wherein, Ca (OH) is added dropwise in step (3)2The time control of emulsion is in 1~2h.
Mixing speed after step (3) is added dropwise is 300~450r/min.
The inventive point of the present invention is that the flocculant that different flocculants are prepared into mixing in the manner of the present invention, finally
The effect of product is single component or 3-5 times of flocculant effect is simply mixed, and is that the present inventor obtains by long-term experiment
Method.
The application method of use in waste water treatment coagulant：
Waste water adds conditioning agent milk of lime, adjusts the pH value of waste water between 6~9 after A/O biochemical treatments, adds useless
Water process coagulant, first stirred 1~2 minute with 300~500r/min speed, then stirred with 60~80r/min speed
10~12 minutes, 1~2 hour is stood, enters the solid separating treatment of water-filling.
Use in waste water treatment coagulant provided by the invention, it is composite coagulant, improves the work of colloidal solid in sludge
Property, improve the reunion performance of sludge, in addition can also be to COD so as to improve the dehydration property of sludgecr, colourity, total CN-Further
It is removed, reduces poisonous and harmful substance in sludge.
