Improve subsequent biological treatment efficiency.It is embodied in biology and can assimilate organic carbon (AOC) and biodegradable dissolubility is organic
Carbon (BDOC) concentration raises.Therefore ozone oxidation can be used for Biological Pretreatment, can be effectively improved subsequent biochemical reaction.
Ozone oxidation and biological treatment are combined, for refractory organic industrial sewage advanced treating, can be by waste water
In persistent organic pollutants exhaustive oxidation decompose, and there is no by-product, do not produce secondary pollution, thus thoroughly solve difficulty fall
Solve a difficult problem for organic industrial sewage pollution control.
MBR technology is that high performance membrane is separated the technology combined with biodegradation, and MBR technology the most in a large number should
For advanced treatment of industrial waste water field, but in industrial wastewater secondary treatment yielding water, residual is the big of difficult for biological degradation mostly
Molecular organic, the biodegradability of waste water is poor, directly uses MBR to process organic removal efficiency the highest.Ozone oxidation can
Significantly change organic molecular structure, effectively larger molecular organics can be converted into small-molecule substance, improve two grades
The biodegradability of water outlet, is the important pretreatment technology of biological treatment.
And inventor discovers how to join together for difficulty ozonation technology and MBR technology in a relatively simple manner
Degraded organic industrial sewage advanced treating field, ensures system treatment effeciency simultaneously, reduces operating cost, is in through engineering approaches application
The problem needing to solve.

Detailed description of the invention
Below the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described reality
Executing example is only a part of embodiment of this utility model rather than whole embodiments.Based on embodiment of the present utility model, this
The every other embodiment that field those of ordinary skill is obtained under not making creative work premise, broadly falls into this practicality
Novel protection domain.
With specific embodiment, advanced treatment apparatus of the present utility model is described further below in conjunction with the accompanying drawings.
Embodiment 1
With reference to Fig. 1, the refractory organic industrial sewage advanced treatment system that the present embodiment provides, by ozone oxidation tower, in
Between pond and MBR pond be composed in series, pending waste water is after water inlet 1 enters ozone oxidation tower 2, with ozone activating QI in oxidizing tower
Body is sufficiently mixed contact, and the hardly degraded organic substance in water, under the Oxidation of ozone gas, a part of oxidized resolves into two
Carbonoxide and water, another part macromolecule hardly degraded organic substance is oxidized resolves into simple low molecule organic matter, and waste water obtains
Processing, the water after process flows out through outlet, enters intermediate pool 3；In intermediate pool 3, part ozone gas remaining in water
Body reacts further with the Organic substance in water, is exhausted by the ozone gas in water, simultaneously due to ozone activating QI in water
The aeration dissolution of oxygen in body, the dissolved oxygen in water is the highest, and in intermediate pool, in holding process, the dissolved oxygen in water contains
