Description

A kind of water color ink wastewater purification treatment equipment

Technical field

The utility model relates to a kind of wastewater purification treatment equipment, and particularly a kind of water color ink wastewater purification treatment equipment, belongs to sewage treatment area.

Background technology

At present, what domestic packed in cases industry generally adopted is water color ink printing technology, in process of production, need to change ink cleaning of graphic arts equipment and can produce a certain amount of printing ink wastewater.Because COD and the colourity of water color ink waste water are generally all very high, not possessing can directly biochemical treatment condition, even if adopt tens times of direct thin up way dilutions even hundred times, thousands of times, the COD of waste water and colourity are also difficult to reach emission standard, have increased again pollution volume, intractability and the processing cost of waste water simultaneously; Adopt to burn, transport outward buried method and also make cost for wastewater treatment very high, easily cause secondary pollution, allow enterprise be difficult to bear.

Utility model content

The purpose of this utility model is to overcome the shortcoming of prior art, provides a kind of high treatment effect, cheaply water color ink wastewater purification treatment equipment.

The purpose of this utility model is achieved through the following technical solutions: a kind of water color ink wastewater purification treatment equipment, it is characterized in that: along purification process technique flow process, be followed successively by with grid, aerator, the equalizing tank of lift pump, PH coarse adjustment pond, PH accurate adjustment pond, one-level coagulation basin, two-stage coagulation pond, with swash plate strainer, the preliminary sedimentation tank of sludge pump, anaerobic pond with combined stuffing, with aerator, the Aerobic Pond of combined stuffing, with center thrust-augmenting nozzle, flow-stopping plate, effluent weir, the second pond of sludge pump, outlet sump, adopt gas blower to carry out aeration, between each adjacent pool, there are connecting water pipe and height fall from high to low, wherein preliminary sedimentation tank is connected with pressure filter through the pipeline of sludge pump is installed with second pond.

Described grid adopts automatically middle grid, and interval of grid strip is 40mm.

Described gas blower adopts rotary blower.

Described pressure filter adopts plate-and-frame filter press.

The utlity model has following advantage: dosage is few, running cost is low; Easy and simple to handle, fully automatic operation; Do not produce secondary pollution; Stable water outlet is up to standard.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

In figure: 1-equalizing tank, 101-grid, 102 aeration tanks, 103-lift pump, 2-PH coarse adjustment pond, 3-PH accurate adjustment pond, 4-one-level coagulation basin, 5-two-stage coagulation pond, 6-preliminary sedimentation tank, 601 hypotenuse strainers, 602-sludge pump, 7-anaerobic pond, 701-combined stuffing, 8-Aerobic Pond, 801-aerator, 9-second pond, 901 center thrust-augmenting nozzles, 902-flow-stopping plate, 903-effluent weir, 10-outlet sump, 11-gas blower, 12-pressure filter.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further described, but protection domain of the present utility model is not limited to the following stated.

As shown in Figure 1, a kind of water color ink wastewater purification treatment equipment: be followed successively by the equalizing tank 1 with grid 101, aerator 102, lift pump 103 along purification process technique flow process, PH coarse adjustment pond 2, PH accurate adjustment pond 3, one-level coagulation basin 4, two-stage coagulation pond 5, preliminary sedimentation tank 6 with swash plate strainer 601, sludge pump 602, anaerobic pond 7 with combined stuffing 701, Aerobic Pond 8 with aerator 801, combined stuffing 701, with the second pond 9 of center thrust-augmenting nozzle 901, flow-stopping plate 902, effluent weir 903, sludge pump 602, outlet sump 10.Adopt gas blower 11 to carry out aeration, between each adjacent pool, there are connecting water pipe and height fall from high to low, wherein preliminary sedimentation tank 6 is connected with pressure filter 12 through the pipeline of sludge pump is installed with second pond 9, grid 101 adopts automatically middle grid, interval of grid strip is 40mm, gas blower 11 adopts rotary blower, and pressure filter 12 adopts plate-and-frame filter press.

The utility model technical process is as follows: sewage is introduced into equalizing tank 1, in equalizing tank, be provided with mechanical grille 101, after sewage, enter successively PH coarse adjustment pond 2, PH accurate adjustment pond 3, one-level coagulation basin 4, two-stage coagulation pond 5, in PH equalizing tank, mainly add sodium hydroxide, in coagulation basin, mainly add PAM and PAC, in coagulation basin water outlet, contain great quantity of floc suspended substance, therefore sewage enters preliminary sedimentation tank 6, preliminary sedimentation tank 6 adopts ramp type settling tank, enter afterwards anaerobic pond 7, macromolecule contaminant is degraded to small molecules pollutent, then enter Aerobic Pond 8, most of pollutent is removed at Aerobic Pond 8, Aerobic Pond 8 water outlets enter second pond 9, last sewage enters outlet sump 10 after precipitation.

The day processing waste water ability 100t of now take is example, the in the situation that of surplus with due regard to, each pond reference volume is as follows: equalizing tank 1 is that 50m3, PH coarse adjustment pond 2 are 3 m3, PH accurate adjustment pond 3 is 3 m3, one-level coagulation basin 4 is 3m3, and two-stage coagulation pond 5 is that 3 m3, preliminary sedimentation tank 6 are that 12m3, anaerobic pond 7 are that 20m3, Aerobic Pond 8 are that 50m3, second pond 9 are that 12m3, outlet sump 10 are 6m3.Grid 101 is selected automatically middle grid, interval of grid strip 40mm, and lift pump 103 and sludge pump 602 all adopt WQ10-7-0.75 type, and gas blower 11 is HC-501 type, and dosing adopts volume pump metering dosing, and pressure filter 12 is XMY30/630-UB type.
