Description
[technical field]
This utility model relates to a kind of waste gas utilization device, is specifically related to a kind of ozone tail gas and utilizes device, belongs to technical field of environment protection equipment.
[background technology]
Ozone has higher oxidation-reduction potential (2.07V) in water, is commonly used to carry out sterilizing, deodorization, decolouring etc., has a wide range of applications in drinking water treatment.In recent years, ozonation technology is constantly improved and is strengthened, it is combined into multiple new and high technology with physics, chemistry and bioscience, not only effect stability, but also it is strong to have oxidability, reaction is fast, easy to use, do not produce the advantages such as chemistry secondary pollution, at present by the advanced treatment process being more used in big city Sewage Plant.But, ozone has toxicity, and in air, ozone concentration reaches 0.1mg/m3Time just the eyes of people, nose, larynx and respiratory tract are produced stimulation, 0.01～0.02mg/m3Time can smell stink, therefore ozone tail gas typically will be emitted into air after ozone tail gas destructor is by remaining ozone decomposed again.
Research currently for ozone tail gas has focused largely on the decomposition of tail gas, to prevent ozone from causing secondary pollution.But, owing to the efficiency of ozone generation of ozonator is low, in foul smell tail gas, oxygen (tail oxygen) content is still up to more than 80%, and utilization rate is low, is the most all directly discharged into air because it is harmless, thus causes a large amount of wastes of energy.
Additionally, the aeration time needed for biochemical aeration method conventional in sewage disposal process mainly uses air aeration, air aeration is longer, and easily there is sludge bulking.And pure oxygen aeration is compared with air aeration, it has following characteristics: (1) oxygen transfer rate is fast, and activated sludge concentration is high, therefore can improve organic removal rate, make Aeration tank volume be substantially reduced；(2) surplus sludge volume is few, and mud has good settleability, is not susceptible to sludge bulking；(3) Aeration tank can keep the dissolved oxygen of high concentration, have preferable anti impulsion load ability.If but utilized merely pure oxygen aeration, then would need to rely on sewage farm self to prepare oxygen, the operating cost of pure-oxygen aeration method can be caused to rise, increase management difficulty.
Therefore, for solving above-mentioned technical problem, necessary offer one ozone tail gas utilizes device, to overcome described defect of the prior art.
[utility model content]
For solving above-mentioned technical problem, the purpose of this utility model is to provide a kind of ozone tail gas to utilize device, and it can effectively reduce energy consumption, and after ozone tail gas destroys in addition, most ozone is converted into O2, this gas is passed through Aeration tank, and the advantage of pure oxygen aeration is also fully demonstrated, and improves the water quality of water outlet.
For achieving the above object, the technical scheme that this utility model is taked is: a kind of ozone tail gas utilizes device, and it includes Aeration tank, sedimentation tank, fibre turntable filter chamber, ozone contact tank, activated carbon filter, tail gas breaking plant I, tail gas breaking plant II and ozone preparation station；Wherein, described Aeration tank, sedimentation tank, fibre turntable filter chamber, ozone contact tank, activated carbon filter are sequentially connected with；Described tail gas breaking plant I is connected between ozone contact tank and Aeration tank；Described tail gas breaking plant II is connected between activated carbon filter and Aeration tank；Described ozone is prepared station and is respectively connecting to ozone contact tank and activated carbon filter.
Ozone tail gas of the present utility model utilizes the device to be also: have mud return line and mud discharging pipe bottom described sedimentation tank.
Compared with prior art, this utility model has the advantages that
Ozone tail gas the most of the present utility model utilizes device to combine the energy-saving and cost-reducing advantage with pure oxygen aeration of waste gas utilization, can accelerate oxygen transfer rate to a certain extent, can reduce air blast machine room and blast air capacity, reduce power consumption.
Ozone tail gas the most of the present utility model utilizes device, enters the residual quantity of ozone in the tail gas of Aeration tank and is less than 0.1mg/L, and a small amount of ozone contributes to sterilizing, improves the safety of water outlet.
[accompanying drawing explanation]
Fig. 1 is the schematic diagram that ozone tail gas of the present utility model utilizes device.
[detailed description of the invention]
Refer to shown in Figure of description 1, this utility model utilizes device for a kind of ozone tail gas, and it is prepared several parts such as station 6 and forms by Aeration tank 1, sedimentation tank 2, fibre turntable filter chamber 3, ozone contact tank 4, tail gas breaking plant I7, activated carbon filter 5, tail gas breaking plant II8 and ozone.
Wherein, described Aeration tank 1, sedimentation tank 2, fibre turntable filter chamber 3, ozone contact tank 4, activated carbon filter 5 are sequentially connected with；Mud return line 21 and mud discharging pipe 22 is had bottom described sedimentation tank 2.
Described tail gas breaking plant I7 is connected between ozone contact tank 4 and Aeration tank 1；Described tail gas breaking plant II8 is connected between activated carbon filter 5 and Aeration tank I.
Described ozone preparation station 6 is respectively connecting to activated carbon filter 5 and ozone contact tank 4.
The method utilizing ozone tail gas of the present utility model to utilize is as follows:
1), when bringing into operation, after water inlet enters Aeration tank 1, open blast aeration machine and blast air to Aeration tank 1, the time of staying 37 hours in Aeration tank, Aeration tank 1 water outlet carries out mud-water separation after entering sedimentation tank 2, this stage residence time is 6 hours, and then this water outlet enters fibre turntable filter chamber 3 and removes the float in water further, and water outlet enters ozone contact tank 4, and open the ozone that ozone preparation station 6 prepares, add H2O2And tail gas breaking plant 8, the ozone contact tank time of staying is 1 hour, and then water outlet enters activated carbon filter 5, open ozone preparation station 6 simultaneously and lead to the valve of activated carbon filter 5, and open tail gas breaking plant 7, and lead to the valve at Aeration tank 1,30 minutes activated carbon filter 5 time of staying.
2), after stable a period of time, in Aeration tank, 37 hours time of staying shortened to 33 hours, and remaining process section time of staying and added amount of chemical all keep constant.
Experimental data is as follows: when ozone tail gas does not utilize, and its Aeration tank water inlet index is as follows: CODCr: 480-500mg/L；Colourity: 130-150 times, activated carbon filter effluent quality index is as follows: CODCr: 70-80mg/L；Colourity: 10-15 times；
After ozone tail gas utilizes, its Aeration tank water inlet index is as follows: CODCr: 480-500mg/L；Colourity: 130-150 times, activated carbon filter effluent quality index is as follows: CODCr: 60-70mg/L；Colourity: less than 10 times.
By above-mentioned experiment, it can be deduced that to draw a conclusion: process ozone tail gas by the method, outlet effect can be made more preferable, and aeration time can be shortened, reduce processing cost.
Above detailed description of the invention is only the preferred embodiment of this creation, and not in order to limit this creation, all any modification, equivalent substitution and improvement etc. done within this spirit created and principle, within should be included in the protection domain of this creation.
