2 can separate the solid particle of heavier mass in dyeing and printing sewage and impurity, so that the part removed in dyeing and printing sewage is miscellaneous
Matter.Dyeing and printing sewage is sequentially sent to acid-base neutralization pond 3, flocculation deposition apparatus 4, oxidation pond 5 through suction pump after being cooled to room temperature and adds
It, can be successively by suspended matter, color additive, high-molecular compound and the sulphur in dyeing and printing sewage by each processing unit in medicine pond 6
The different types of pollutant such as compound is removed step by step, so that being capable of forming dyeing and printing sewage after treatment meets discharge standard
Water quality and be recycled.For sewage after entering flocculation cylinder 401, flocculant pipe 23 send the flocculant in flocculant cylinder 405
Enter to flocculate in cylinder 401, react flocculant and sewage, thus by suspended particulate substance and macromolecule chemical combination in sewage
It after object is polymerize and removes, the conveying capacity of flocculant can also be adjusted by throttle valve 24, make the mixing of flocculant and sewage
Ratio can reach best.Flocculant and sewage can be stirred it in hybrid reaction by stirring flabellum 10, improve
The reaction efficiency of mixture simultaneously react each reactant in sewage can sufficiently, to make sewage after the reaction
The floc sedimentation of formation can polymerize completely, avoid fine particle or high-molecular compound with a small amount of flocculant the shape after insufficient react
At the lesser floc sedimentation of diameter, influences the treatment effeciency of device sewage and pollute.It can also will be changed by the first water inlet pipe 13
Cooling water after heat is sent into the heating cylinder 404 in 401 outside of flocculation cylinder, and cooling water is allow to pass through the side wall for the cylinder 401 that flocculates
Sewage in flocculation cylinder 401 is heated, the reaction temperature of sewage and flocculant is enable to reach 20~30 DEG C, 20~30 DEG C
It is the optimal reaction temperature of sewage and flocculant, can be avoided because reacting not exclusively or because of reaction caused by too high or too low for temperature
The problem for excessively causing floc sedimentation diameter too small, further improves the flocculation efficiency and flocculating effect of flocculation deposition apparatus 4；Pass through
The stirring of stirring flabellum 10 can also mix sewage, so that the sewage of different location is able to maintain same temperature, further
Improve the heating efficiency of cooling water.When the water temperature in the cylinder 401 that flocculates reaches 30 DEG C or more, worker can be according to temperature sensing

The floc sedimentation and solid particle formed after reaction can be sent out under the effect of the rotating centrifugal of sewage to the surrounding of flocculation cylinder 401
It dissipates, and flow to 12 side of guide plate with water flow, the lasting rotating effect for being then subjected to water flow flows diagonally downward along guide plate 12
To flocculation deposition cylinder 403.Stirring flabellum 10 stops after rotating a period of time and precipitates to sewage, makes the sludge in sewage
It can be precipitated to flocculation 401 bottom of cylinder completely.After precipitating a period of time, worker opens suction pump and passes through 112 He of suction hose
Lifting hose 113 detaches the sewage to flocculate in cylinder 401, suction hose 112 can be made to remain at sewage by floating ball 114
Upper layer enables suction hose 112 to reduce the influence caused by flocculation 401 base sludge of cylinder as far as possible when drawing water, sludge is avoided to exist
It is detached to be mixed into sewage again after effect and be pulled out, improve flocculation deposition apparatus 4 to the separating effect of sludge.Suction hose
112 detach along 111 pairs of top sewage of guiding axis under the effect of gravity, when wastewater level reaches restraining position,
Worker can stop pumping according to the overhang that wire drawing sensor 20 is shown, flocculation is then deposited cylinder through sludge recyclable device 21
Sludge recovery processing in 403 completes to work to the flocculation sedimentation of dyeing and printing sewage and improve flocculation and separation effect to sewage
Fruit.
Sewage is sent into after flocculation deposition apparatus 4, oxidation pond 5 and dosing pond 6 are successively handled through the second water inlet pipe 16 secondary
Sedimentation basin 7 can carry out third time precipitating to sewage by secondary sedimentation tank 7, make sewage anti-through oxidation pond 5 and dosing pond 6
The particulate matter that should be formed afterwards can be separated through secondary sedimentation tank 7, further improve the separating effect of sewage.Sewage is precipitating
Enter activated carbon adsorption tank 8 afterwards, it can be by peculiar smell composition, the aromatic compound, low point in sewage by activated carbon adsorption tank 8
Sub- organic matter and synthesis of organic substance are adsorbed and are removed；And due to the cooperation of flocculation deposition apparatus 4 and secondary sedimentation tank 7
Through by sewage macromolecule organic and solid particulate matter separate completely, so that it is right to greatly improve activated carbon adsorption tank 8
The adsorption effect of residual organic substances keeps activated carbon adsorption tank 8 that sewage treatment is complete, further improves the utility model
To the treatment effect of dyeing and printing sewage.Sewage is collected after adsorbing sewage by recyclable device 9 by activated carbon adsorption tank 8, is completed
Processing work to sewage.The utility model can be in step successively to different volumes in sewage and quality during processing
Solid particle and floc sedimentation carry out separation removal, and the suspended particulate not removed can be carried out to circular treatment, and treatment effeciency is high, handles
Effect is good.
