Description
Technical field
The utility model belongs to coating waste-water processing technology field, and in particular to a kind of coating waste-water processing system.
Background technology
Coating production enterprise mainly produces water paint, solvent based coating and powder coating, wherein solvent based coating and powder
The production process of body coating does not generate waste water, and the production process of water paint generates technique wash water.The processing of technique wash water
Essentially consist in the SS and COD of removal high concentrationCr, pretreatment removal SS is generally preferably first passed through, then removed with microbiological processes
CODCr.The SS of raw water is dispersed in water with latex state, while also there are various surfactants and macromolecule organic in water,
So it is first pre-processed using coagulation process.After pretreatment, the biodegradability of water outlet is still poor, subsequently can be used anaerobism with
The biological treatment of aerobic combination.
Most of coating waste-water processing system is mostly low there are water utilization rate both at home and abroad at present, the consumption of new water
Greatly, processing cost is not only increased, and does not meet the theme for saving water resource instantly, is in addition easily managed in processing procedure
The situation that road blocks, greatly affected the working efficiency and working performance of whole system.
Utility model content
In view of the deficienciess of the prior art, the utility model provides, a kind of working efficiency is high, performance is stable and water resource
The high coating waste-water processing system of utilization rate.
The utility model is achieved through the following technical solutions：
A kind of coating waste-water processing system, including collecting-tank, coagulative precipitation tank, regulating reservoir, two-stage coagulation pond, sedimentation basin,
Intermediate pool, anaerobic pond, aerobic tank, secondary settling tank, clear water reserviors, sludge-tank, static mixer, belt filter press and transport vehicle, institute
It is suitable to state collecting-tank, coagulative precipitation tank, regulating reservoir, two-stage coagulation pond, sedimentation basin, intermediate pool, anaerobic pond, aerobic tank and secondary settling tank
Secondary connection, is provided with startup diaphragm pump between the collecting-tank and coagulative precipitation tank, the secondary settling tank and clear water reserviors, sludge-tank are equal
Connection, the sludge-tank are sequentially connected with the static mixer, belt filter press and transport vehicle, the belt filter press also with
The regulating reservoir connection.
Further, the coagulative precipitation tank, sedimentation basin are connect with the sludge-tank.
Further, the first elevator pump, the intermediate pool and anaerobism are provided between the regulating reservoir and two-stage coagulation pond
The second elevator pump is provided between pond.
Further, further include pipeline cleaning system, by water butt and pipeline cleaning pump group into.
Compared with prior art, the beneficial effects of the utility model are：
1st, the utility model belt filter press treated filtrate and ejected wash water enter regulating reservoir and are recycled, significantly
The utilization rate of water is improved, reduces operating cost；
2nd, the utility model further includes pipeline cleaning system, after having conveyed waste water every time, starts pipeline cleaning pump to entire
It is cleaned inside the pipeline of system, particulate matter is effectively prevent to block pipeline, ensures the stable of whole system；
3rd, the utility model good waste water treatment effect, the biodegradability of water outlet improves, convenient for being widely used to promote.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
A kind of coating waste-water processing system as shown in Figure 1, including collecting-tank, coagulative precipitation tank, regulating reservoir, two-stage coagulation
Pond, sedimentation basin, intermediate pool, anaerobic pond, aerobic tank, secondary settling tank, clear water reserviors, sludge-tank, static mixer, belt filter press and
Transport vehicle, the collecting-tank, coagulative precipitation tank, regulating reservoir, two-stage coagulation pond, sedimentation basin, intermediate pool, anaerobic pond, aerobic tank with
And secondary settling tank is sequentially connected with, and startup diaphragm pump, the secondary settling tank and clear water are provided between the collecting-tank and coagulative precipitation tank
Pond, sludge-tank are all connected with, and the sludge-tank is sequentially connected with the static mixer, belt filter press and transport vehicle, the band
Formula filter press is also connect with the regulating reservoir.Further, the coagulative precipitation tank, sedimentation basin are connect with the sludge-tank.
Further, the first elevator pump (not identified in figure) is provided between the regulating reservoir and two-stage coagulation pond, it is described
The second elevator pump (not identified in figure) is provided between intermediate pool and anaerobic pond.Further, pipeline cleaning system (figure is further included
In do not identify), by water butt and pipeline cleaning pump group into.
Specific workflow is：Technique wash water is collected in collecting-tank, is then delivered to by starting diaphragm pump
The coagulative precipitation tank of waste water processing station farther out, coagulative precipitation tank is interior to add in PAC (inorganic salt coagulant), carries out coagulating,
PAM (non-ionic high polymer coagulant) is added after 30min further to react, and is staticly settled after coagulating, sludge is discharged into
Sludge-tank, supernatant are discharged into regulating reservoir, are then lifted into two-stage coagulation pond by the first elevator pump, add in PAC and PAM into
Row coagulating enters back into sedimentation basin and carries out separation of solid and liquid, and the sludge after separation is discharged into sludge-tank, and supernatant enters intermediate pool,
Waste water in intermediate pool sequentially enters anaerobic pond and aerobic tank after the promotion of the second elevator pump and carries out anaerobic and aerobic life respectively
Change reaction, oil removal is finally separated in secondary settling tank, water outlet enters clear water reserviors, and sludge is arranged with coagulative precipitation tank and sedimentation basin
The sludge put enters sludge-tank together, handled subsequently into static mixer with reach between different fluid fine dispersion and
It is sufficiently mixed, is finally carried out dehydrating with belt type sludge filter press, the sludge cake generated after dehydration is transported to by transport vehicle
The position needed, filtrate and ejected wash water enter regulating reservoir and are recycled.
In conclusion the only preferred embodiment of the utility model, is not used for limiting the utility model implementation
Range, the equivalent change carried out by all shapes according to described in the utility model claims range, construction, feature and spirit is with repairing
Decorations, should all be included in the right of the utility model.
