Abstract
The invention discloses an air flotation device for cleaning floating objects in sewage in a printing and dyeing mill, which belongs to sewage treatment equipment. The air flotation device is an air flotation device for cleaning floating objects in an on-line sewage treatment system. The air flotation device comprises a water tank of which the upper end opening takes the shape of a square, wherein at least three air inlets are formed in the lower part of a side wall of the water tank; a guide plate is arranged inside the water tank; the water tank is partitioned into a sewage area and a clean water area by the guide plate; at least one water collection tube is arranged in the clean water area; a sewage collecting tank and a floating object drainage hole are formed in the outer side of the side wall of the water tank with the air inlets; a water collecting chamber and a clean water outlet are formed in the outer side of the side wall of the water tank opposite to the sewage collecting tank; the water collecting tube is communicated with the water collecting chamber through the water outlet; a scraping device is arranged in match at the upper end of the water tank through a track. By adopting the device, the pretreatment sewage emission is approximate to zero, so that not only is the expense for sewage treatment of companies reduced, but also the increase of COD content due to the fact that the pretreatment wastewater is directly discharged to a sewage treatment system is reduced.
Description
Technical field
The invention belongs to sewage disposal device, particularly in a kind of online Sewage treatment systems, remove the air-floating apparatus that floating matter is used.
Background technology
At present, printing and dyeing enterprise will produce a large amount of sewage with a large amount of water every day simultaneously, and along with industrialization development water resources is more and more precious, the large amount of sewage of generation incurs great expense and carries out purifying treatment; Product one garment material and bedclothes etc. are textile, the printing and dyeing enterprise of polyester-cotton blend, main water board has desizing machine, boils and float machine, mercerizing tange, rinsing machine, at present the sewage of these equipment after using is all to concentrate to be transported to a large Sewage treatment systems and to process, then discharge; Each equipment continuous firing can produce a large amount of waste water, focuses on also and can consume very large production cost; The composition of different operation generation water is different, but the front-end processing of most of operations, owing to there is no the intervention of dyestuff, the sewage producing, not containing dyestuff, can enter recycling, and prior art cannot solve the problem of online middle water handling reclamation, and the sewage of above-mentioned each equipment pre-treatment is mainly sweater, dust, organic impurity, PVA slurry, be that these sewage contain more than 90% floatability thing, therefore only need to remove these floatability things, can reuse.
Summary of the invention
In order to address the above problem, the invention provides a kind of printing and dyeing mill for removing the air-floating apparatus of sewage floating matter.
The present invention includes the square water tank of upper end open, bottom at a sidewall of described water tank arranges at least three inlet mouths, one drainage plate is set in described water tank, described drainage plate is obliquely installed and is relative with described inlet mouth, the lower end of described drainage plate, dual-side are fixing with the sidewall sealing of described water tank respectively, described drainage plate becomes contraminated zone, clear water zone by water tank lattice, on sidewall at the water tank in described contraminated zone near bottom surface, sewage import is set, in described clear water zone, at least one header is set, described header is near described water tank bottom; Be provided with sewage sump with the described outside that is provided with the water tank sidewall of inlet mouth, described sewage sump is communicated with described water tank, in the lower bottom of described sewage sump, floating matter sewage draining exit is set, and the bottom surface of described sewage sump is lower than the described sidewall that is fixed on the water tank of inlet mouth; Arranged outside one collect cavity at the water tank sidewall relative with described sewage sump, the water outlet that described header passes through is communicated with described collect cavity, the lower surface of described collect cavity arranges clear water output, described clear water output is lower than described water tank upper port, bottom in described water tank clear water zone arranges throw out sewage draining exit, in described water tank upper end, by track, coordinates scraper.
When the present invention uses, the sewage that board preorder produces enters the contraminated zone of water tank by sewage import, water is played or sent into a plurality of inlet mouths in sewage, gas mixture forms thrust upwards in contraminated zone, floating matter floating in sewage, the floating matter climbing up on top of the water is delivered in sewage sump and is discharged by scraper, what overflow to drainage plate opposite side is clear water, formed clear water zone, clear water is transported to collect cavity by header, then by clear water output, deliver to catchment and fill with or directly deliver to board preorder for recycling, by this device, cleared up in sewage 90% impurity, it is floating matter, other throw out parts of 10% are discharged by throw out sewage draining exit, a part is along with clear water is sent, but these a small amount of impurity do not affect board water, by this device, the clear water direct reuse of generation, does not need to deliver to sewage disposal and manages everywhere, compared with prior art, dirty Water reuse rate reaches 90%, only has the water of 10% a small amount of left and right along with floating matter is drained, and along with floating matter impurity is got rid of outside machine automatically, by collecting, can by burning, process with fuel mix, is converted into heat energy recycling, in sum, by this device can so that pre-treatment discharge of wastewater be almost equal to zero, not only saved the expense of business processes sewage, can also reduce because pre-treatment direct discharging of waste water causes the rising of COD content to Sewage treatment systems, avoid causing the death of useful organisms mushroom in treatment tank because COD content raises, greatly reduce sewage disposal expense and difficulty, this device can greatly reduce the discharge of sewage total amount, can solve the restriction of dye-works's sewage flow rate to production production capacity.
The present invention is at least two at described throw out sewage draining exit, both sides at described each throw out sewage draining exit arrange respectively slope board, the relatively V-shaped layout of slope board of described each throw out sewage draining exit both sides, the bottom of described slope board, two side ends are separately fixed on described water tank bottom surface and sidewall, the upper end of a slope board of described the most close described drainage plate and the sealing of described drainage plate are fixing, the upper end of a slope board of the most close described water tank sidewall and the sealing of described water tank sidewall are fixing, and the upper end of described other adjacent each slope boards in middle part is sealedly and fixedly connected; By above-mentioned each slope board, throw out is converged to throw out discharge port, facilitate throw out to discharge.
The upper end of drainage plate of the present invention is higher than 2/3rds of described water tank height; Limiting the height of drainage plate, is clean in order to guarantee the water of header extraction, avoids by the sewage pollution in contraminated zone.
Header of the present invention is arranged on a plurality of prosopyles is set on the pipeline section in described water tank.
The present invention arranges a water absorption tube in described water tank, and described water absorption tube is arranged on described clear water zone;
