Specific embodiment

Specific embodiment of the present utility model is described in detail with reference to the accompanying drawing.

It is flowed into conditioning tank as shown in Figure 1, the production waste water in processing plastic wire-drawing each stage flows automatically under gravity, Sulfuric acid is added in conditioning tank, the preliminary pH to 7-10 for adjusting waste water, then promoted the alkaline waste water regulated by elevator pump To air floatation machine, and flocculant poly aluminium chloride (PAC) and polyacrylamide (PAM), aluminium polychloride are added in air floatation machine (PAC) molecule and polyacrylamide (PAM) molecule, which build bridge the suspended particles being suspended in waste water to adsorb, forms flocculate, then Using pressure air-dissolving method, i.e., waste water to be processed is first pressurized to 3-4kg/cm2 with water pump, is then fed into the dissolving of special arrangement In, air is substantially soluble in water in tank, then dissolving is put into air floatation machine, is subtracted suddenly in air floatation machine through release To normal pressure, the supersaturated air being at this moment dissolved in the water is escaped from pond in the form of micro air bubble, by suspended particle in water or Elaioleucite takes the water surface to and forms dross, scrapes the dross of formation with Slag Scraping Device be discharged into sludge-tank later.Supernatant after air bearing Gravity flow inflow acidification pool under the effect of gravity, in acidification pool plus sulfuric acid adjusts clear liquid to acidity, and then acid clear liquid gravity flow is flowed Enter Fenton tower, in Fenton tower using Fenton reagent to acid clear liquid carry out advanced oxidation, remove waste water in 50% or more it is organic Object, the waste water after peroxidating flow into reaction tank from Fenton tower, in reaction tank plus after the PH to neutrality of alkali neutralization waste water again Flocculant poly aluminium chloride (PAC) molecule and polyacrylamide (PAM) is added, the waste water after abundant adsorption-flocculation flows into Sedimentation basin, in sedimentation basin after precipitating after a period of time, clear liquid floats, and flocculate sinks, work of the supernatant in gravity After flowing into reduction pond with lower gravity flow, the flocculate residue in sedimentation basin is discharged into sludge-tank, then adds Asia in reduction pond Obtained waste water, to remove remaining oxidant in waste water, is then pumped into biochemistry with self priming pump as reducing agent by sodium sulphate Integration apparatus is handled, adds MBR film method to handle waste water using AO technique in a device, waste water is first with certain speed stream Through biologic packing material, cover with biomembrane on filler, under the collective effect of biomembrane and activated sludge, by AO technique into The operation change of water mode and aeration mode is realized aerobic nitrification and anaerobic denitrifying denitrogenation, dephosphorization and is further removed Organic matter in waste water, the water outlet being purified at this time is pumped into active carbon filter by self priming pump, and is inhaled by active carbon It is discharged into the total discharge outlet of plant area after flowing into clear water reserviors after attached effect progress advanced treating, later to MBR membrane cisterna, active carbon filtering Device, clear water reserviors are backwashed, and remove the impurity being trapped in filter material layer, filter tank is made to restore filter capacity in a short time.

Sludge gravity flow in air floatation machine and sedimentation basin flows into sludge-tank, and MBR membrane cisterna excess sludge is pumped into dirt by self priming pump Mud sump, the sludge settled in sludge-tank are pumped into sludge drying pond by sludge pump and carry out nature desiccation, and residual moisture leads to respectively It crosses natural evaporation bottom of pond naturally osmotic pipe to be back to sludge-tank overflow is to conditioning tank again, after moisture content reduces, sludge obtains desiccation Outward transport.

Basic principles, main features, and advantages of the present invention has been shown and described above.This reality It is not restricted to the described embodiments with novel, the above embodiments and description only describe the originals of the utility model Reason, the utility model also has various changes and improvements on the premise of not departing from the spirit and scope of the utility model, these changes Change and improvement is both fallen in the range of claimed invention.The utility model requires protection scope is by appended right Claim and its equivalent define.
