For achieving the above object, the technical scheme that the utility model is taked is: a kind of high tower Orygen enriched aeration device, and it comprises air compressor machine, oxygen main frame, inlet pipe, high tower aeration tank, triphase separator and water suction pump; Wherein, described air compressor machine is connected successively with oxygen main frame; Described inlet pipe one end is connected on oxygen main frame, and it extends into high tower aeration tank; The bottom of described high tower aeration tank is provided with a water inlet pipe, and top is provided with described triphase separator; Described high tower is also provided with a circulation tube on aeration tank, and water suction pump is arranged on circulation tube.
High tower Orygen enriched aeration device of the present utility model is further set to: be provided with vacuum breaker, strainer in described inlet pipe; The end of this inlet pipe is provided with a water of condensation outlet valve.
High tower Orygen enriched aeration device of the present utility model is further set to: on described triphase separator, connect rising pipe and exhaust collection pipe.
High tower Orygen enriched aeration device of the present utility model is further set to: the height of described high tower aeration tank is 15 ~ 20m, and gas-water ratio is 1:5.
High tower Orygen enriched aeration device of the present utility model is also set to: described circulation tube extends into 2/5 place of high tower aeration tank height.
Compared with prior art, the utlity model has following beneficial effect:
1. high tower Orygen enriched aeration device of the present utility model, compared with conventional pure oxygen aeration device, has little, simple to operate, the low gas-water ratio of floor space and can reach the effect that conventional air aeration is realized, and economic dispatch plurality of advantages more.
2. high tower Orygen enriched aeration device of the present utility model can be by the effect of water suction pump, then in conjunction with the effect of aeration, reaches the state of the full pond of effective formation admixture activation, can effectively shorten aeration time, power cost saving.
3. high tower Orygen enriched aeration device of the present utility model is provided with triphase separator, has collected the tail gas that oxygen-enriched aeration produces, and the investment of odor treatment will reduce greatly; Meanwhile, oxygen-enriched aeration, because the concentration of oxygen is higher, can effectively suppress some and detest the growth of (holding concurrently) gas bacterium, alleviates the intensity of foul smell.
Brief description of the drawings
Fig. 1 is the schematic diagram of high tower Orygen enriched aeration device of the present utility model.
Embodiment
Refer to shown in Figure of description 1, the utility model is a kind of high tower Orygen enriched aeration device, and it is made up of several parts such as air compressor machine 1, oxygen main frame 2, inlet pipe 3, high tower aeration tank 4, triphase separator 5 and water suction pumps 6.
Wherein, described air compressor machine 1 is connected successively with oxygen main frame 2.This oxygen main frame 2 is for the preparation of oxygen, and it adopts PSA method Preparation of oxygen, and it is 0.2MPa that air compressor machine 1 makes the oxygen pressure that oxygen main frame 2 produces.Due to on-the-spot oxygen, handling and the transport of oxygen are removed from.
Described inlet pipe 3 one end are connected on oxygen main frame 2, and it extends into high tower aeration tank 4.The pure oxygen that this inlet pipe 3 is prepared oxygen main frame 2 blasts in high tower aeration tank 4.Be provided with vacuum breaker 7, strainer 8 in described inlet pipe 3, described vacuum breaker 7 and strainer 8 can effectively prevent sewage backflow.Be provided with a water of condensation outlet valve 9 in the end of described inlet pipe 3, can effectively get rid of by this water of condensation outlet valve 9 sewage that condenses.
The height of described high tower aeration tank 4 is 15 ~ 20m, and gas-water ratio is 1:5, and its bottom is provided with a water inlet pipe 10, and top is provided with described triphase separator 5.On described high tower aeration tank 4, be also provided with a circulation tube 11, water suction pump 6 is arranged on circulation tube 11.Described circulation tube 11 extends into 2/5 place of high tower aeration tank 4 height, and it can enter the mixed solution circulation in high tower aeration tank 7 in high tower aeration tank 7, can make the state of full pond in mixing like this in conjunction with the effect of oxygen.
On described triphase separator 5, connect rising pipe 12 and exhaust collection pipe 13.This triphase separator 5 can effectively be controlled the loss of mud, and collect the tail gas producing in oxygen-enriched aeration, because gas-water ratio is little, the tail gas amount (foul smell amount) producing is also little, simultaneously, oxygen-enriched aeration, because the concentration of oxygen is higher, can effectively suppress some and detest the growth of (holding concurrently) gas bacterium, alleviates the intensity of foul smell.
Utilize the method for high tower Orygen enriched aeration device treatment of dyeing and printing of the present utility model as follows: certain printing and dyeing enterprise is disposed to high tower aeration tank 4 by the water outlet of hydrolytic tank by water inlet pipe 10, be 12h in the residence time of high tower aeration, gas-water ratio is controlled at 1:5, and the tail gas of collection accesses equalizing tank by exhaust collection pipe 13.
Before treatment of dyeing wastewater, its water-quality guideline is as follows: COD
cr: 1200mg/L; PH:10.5, colourity is 450 times, sulfide is 8mg/L.After hydrolytic tank is processed, COD
crfor 550mg/L, pH:8.10, colourity is 500 times, and sulfide is 70mg/L.After this high tower aerating apparatus is processed, COD
crfor 130mg/L, pH:7.50, colourity is 40 times, and sulfide is 0.2mg/L.In addition unnecessary oxygen enters after equalizing tank, and the concentration of sulfide maintains within the scope of 3-5mg/L.
