Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1, efficient degreasing decontamination apparatus of the present utility model is the tank structure integrated, and tank body top is water inlet mixing reactor and clarifying plant, and middle part is collection mud discharging device, and bottom is strainer and backwashing system.Water inlet mixing reactor forms double-skin duct by pipe core 4 and outer tube 3, and be communicated with water inlet pipe 7 bottom pipe core 4, pipe core 4 top is communicated with outer tube 3, is provided with the diffusion shell 6 of taper bottom outer tube 3; Water inlet mixing reactor is fixed on tank body central authorities by fixed support 5 and stuffing frame 2.Be provided with filler 1 in the cavity on stuffing frame 2 top, filler 1 central authorities are provided with top water storage cavity 28 and are communicated with the water distributor 11 of tank body lower part by vertical downcomer 24.Collection mud discharging device is be arranged on the taper sludge hopper 9 into below water mixing reactor, is communicated to the mud discharging mouth 23 of tank body side bottom sludge hopper 9 by shore pipe.Meanwhile, tank body is divided into up and down independently two portions by sludge hopper 9, and downcomer 24 is the unique passages being communicated with top and the bottom cavity.
Water distributor 11 doubles as backwash water shoot, and be communicated with the backwash water port 12 of tank skin, backwash water port 12 is normally closed in working order, only opens when backwash.The below that anthracite coal measure 13, quartz sand layer 14 and supporting layer 15 are arranged in water distributor 11 from top to bottom successively form filtering layer, and anthracite coal measure 13 thickness is 400mm, adopts particle diameter to be the hard coal of 2 ~ 4mm, nut-shell or haydite, to remain oil content in Adsorption water; Quartz sand layer 14 thickness is 300mm, adopts particle diameter to be the quartz sand of 1 ~ 2mm, to retain in filtered water the impurity such as suspended substance; Supporting layer 15 thickness is 200mm, adopts particle diameter to be the cobble of 2 ~ 8mm, to play support effect to quartz sand layer 14 and anthracite coal measure 13, prevents from running material.Filtering layer is stacked on porous filter plate 17, porous filter plate 17 plate face is furnished with several water caps 16, porous filter plate 17 is supported on tank body lower part by filter plate bracing frame 18, and porous filter plate 17 arranged beneath has the gas distribution pipe 19 be communicated with compressed air inlet 20, and tank base is provided with water outlet 22.
The utility model process oil-containing is adopted to contain the technique of turbid wastewater as shown in Figure 2, the oil-containing of iron and steel enterprise's continuous casting or hot rolling workshop is containing suspension content≤300mg/L, water inlet oleaginousness≤130mg/L in turbid wastewater 8, first waste water pump into line mixer by pump after whirling well, PAC and PAM is added respectively in line mixer, produce coagulating, then be promoted to the utility model efficient degreasing decontamination apparatus, in the middle part of tank body, water inlet pipe 7 enters pipe core 4; Waste water first rises to top in pipe core 4, and then changed course realizes the first turnover 27, then declines along the annular region between outer tube 3 and pipe core 4; When through diffusion shell 6, space increases suddenly, and flow velocity sharply reduces, now, oil-containing containing the larger solid dirt of the large metric density in turbid wastewater 8 solid-liquid separation be able to sedimentation under the effect of expansion section 26 velocity contrast, and converges in sludge hopper 9 cone bottom shape and becomes mud 10.Waste water changed course after the second turnover 25 through diffusion shell 6 is risen, and is filtered by the filler 1 of tank deck, and filler 1 is porous stacked filler; Its effect increases the settling area of sewage, and make mud pile up its surface, after mud is accumulated to certain thickness, free skating drops down onto bucket; Oil removing principle of the present utility model adds polymerize aluminum chloride medicament before sewage access arrangement, and after abundant reaction, oil-in-water part formed can the flco of sedimentation, then enters the utility model equipment and removes.Through the filtration of filler 1, can remove suspended substances a large amount of in water inlet and flco, relatively clean water outlet converges to the top water storage cavity 28 of central authorities, and is dropped to the water distributor 11 of tank body lower part by downcomer 24.
Water distributor 11 is the T-shaped Wire wound tube of stainless steel, current are evenly distributed on filtering layer through water distributor 11, then slow through anthracite coal measure 13, quartz sand layer 14 and supporting layer 15 respectively from top to bottom, each filtering layer plays absorption oil content and cuts dirty effect and realizes filtering, in the utility model, anthracite coal measure 13 plays main filtration and cuts dirty effect, and quartz sand layer 14 only has top layer to participate in filtration, water outlet 21 is discharged by water outlet 22, suspension content≤20mg/L, oleaginousness≤8mg/L in final outflow water.Due to the operation with pressure of this device, device water outlet 21 can utilize the direct backwater of overbottom pressure to cooling tower to carry out cooling process, and after cooling tower process, water outlet 21 is from flowing to turbid circulating water pond for production plant reuse.
The utility model is after long term operation, and filtering layer can be polluted, and regularly need carry out backwash.When carrying out backwash, water inlet pipe 7 external valve is closed, backwash water port 12 external valve is opened, compressed air inlet 20 external valve is opened, in the outside outfall sewer be communicated with water outlet 22, water (having pressure) is inner through water outlet 22 access to plant, current are from bottom to top by porous filter plate 17, after water cap 16 uniform water distribution, backwash is carried out to filtering layer, during backwash, current loosen each filtering layer, filtering material particle is made to be in suspended state and collision mutually, and pass into compressed-air actuated effect by gas distribution pipe 19, form the process of cleaning.Because the settling velocity of each metafiltration material in water is different, after backwash terminates, the layering of each metafiltration material natural subsidence, returns to former filtration condition, can again put into operation.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, when without prejudice to the utility model spirit, the utility model can do any type of amendment.Such as the utility model is not limited to process oil-containing containing turbid wastewater, also may be used for processing conventional sewage.
