Oxidation reaction is touched, oxygen is entered by micro- oxygen aeration head 22 in the second tube body 4, for the micro- oxygen aerobic microbiological adhered on filler 23
Oxygen source is provided, micro- oxygen aerobic microbiological opens the phenyl ring of phenyl amines small-molecule substance, and so that it is further broken into degradable has
Machine object so that COD concentration is greatly reduced in waste water；Third tube body 3 is flowed by the waste water of filler 23 to contact with biological anode 24,
The trace oxygen contained in waste water at this time can promote the degradation of remaining phenyl amines small-molecule substance, while 24 table of biological anode
The anaerobe of face attachment decomposes easily biodegradable organics, and generates extra electron, by external circuit, by extra electron
It is supplied to biological-cathode 21, promotes the progress of biological-cathode reaction, has further speeded up the fracture of azo bond, reached decoloration and drop
The effect of low COD, and the product after decomposing can be used as nutriment necessary to anaerobe existence, ensure the micro- life of anaerobism
The growth of object eliminates and manually adds additional nutriment；By waste water the giving up from 2 tube wall of the 4th tube body of biological anode 24
Water outlet aperture 11 flows out.
It by taking acid orange (AO7) waste water from dyestuff as an example, is learnt by detection, when a concentration of 100mg/L of water inlet AO7, outer power-up
When pressure 0.7V, aeration quantity 600mL/min, pH value are 7, hydraulic detention time 12h is repeatedly taken at third thief hole 12
Sample obtains the removal rate of AO7 up to 89.2% ± 2.0%, is repeatedly sampled at waste water tap hole 11, obtain going for AO7
Except rate is up to 92.4% ± 2%.A concentration of 1000mg/L of COD in raw wastewater, COD removal rates are reachable at waste water tap hole 11
95.4% ± 1%.It can be seen that Integral waste water processing unit of the present invention, can effectively remove the dyestuff macromolecular in waste water
Substance reduces the COD concentration of waste water.
The above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although with reference to preferred embodiment to this hair
It is bright to be described in detail, it will be appreciated by those skilled in the art that can technical scheme of the present invention be modified or be waited
With replacing, without departing from the objective and range of the technical program, should all cover in scope of the presently claimed invention.
