Description
Technical field
The open a kind of novel ozone of the present invention and BAF sewage-treatment plant, belong to sewage disposal technology neck
Territory, especially relates to the sewage-treatment plant using ozone oxidation to combine with BAF.
Background technology
Along with socioeconomic development and the growth of population, water resource has become as the restriction of national economy sustainable development
Factor.The water resources crisis that China faces is more acute, and China's water resource per capita is only 1/4th of world's per capita share, warp
The high speed development of Ji, industrial and agricultural production water and total amount of pollutants discharged be continuously increased, and wastewater treatment rate is the highest, has increased the weight of natural water dirty
Dye.Therefore, improve sewage disposal level, develop suitable waste water treating and reutilizing device, be possible not only to conservation of nature environment, also solve
The water scarcity problem having determined current.
Ozone has extremely strong oxidation susceptibility, and its oxidability is only second to fluorine, and higher than chlorine and potassium permanganate, and ozone can be
Decompose voluntarily in short time, there is no secondary pollution, be preferable green oxidation medicament.At present, ozone technology is in water treatment field
Having obtained many application perhaps, ozone not only has the highest sterilization effect, it is also possible to be difficult to raw in oxidation removal water
The organic pollution of thing degraded.But it is used alone ozone oxidation costly, and is only capable of major part larger molecular organics oxygen
Chemical conversion small organic molecule, and Organic substance thoroughly can not be removed.
BAF (BAF) is a kind of sewage treatment technique of the later development 1980s, essence
It is a kind of biomembrance process, in Aeration tank, i.e. fills biologic packing material, utilize pollution in the biomembrane degradation water that filling surface adhere to
The processing unit of thing.Due to selected filler self, the easy attached biological film of filling surface.Biomembrane grow numerous
Kind and the microorganism of quantity, have aerobic bacteria, and hold concurrently oxygen bacterium, anaerobe, so BAF is to the various Organic substances in water
There is a good removal effect, ammonia nitrogen is also had the highest removal efficiency simultaneously.Although but BAF efficiency
Height, the water source being only applicable to sewage of low concentration advanced treating and the micro-pollution of former water processes, it is impossible to remove refractory organic.
At present, the equipment the most ozone oxidation not combined with biological aerated filter in sewage disposal process, effectively carry
Rise the filter effect of former water, therefore just have the proposition of the present invention.
Summary of the invention
For the deficiency of sewage water filtration technology, the invention provides a kind of ozone and fill with BAF sewage disposal
Putting, this device is suitable for processing high concentration, the organic sewage of difficult degradation, and there is low cost, high efficiency, equipment is simple, be prone to behaviour
Make, produce water water quality advantages of higher.

Use tail gas decomposer, the ozone in tail gas is decomposed further, the safety of protection environment.
4) after ozone oxidation, the dissolved oxygen in water body is greatly improved, and makes the aeration rate in follow-up BAF significantly
Reduce, reduce energy consumption.
BAF backwash of the present invention uses the combination of spiral aeration process and pulse air punching and the punching of continuous water
Mode, the recoil air-flow moment of some strength enters filtering layer makes filtering layer be in variable speed expansion state with solid stream of water jointly, biological
Film and impurity fast-falling under strong shearing, collision effect, after instant airflow pulse, gradually stablizes also when expanding filtering layer
Sedimentation, opens gas again when not yet reaching dense state, then filtering layer starts again the violent state change of another cycle.Wherein current begin
The result playing the effect frequent operation uniformly recoiling and rinsing filtering layer eventually is to enhance back flushing process, thus in water consumption, gas consumption
Measure little in the case of, it is ensured that higher backwash efficiency substantially increases backwash effect.
