Specific embodiment

The utility model is described in further detail with reference to the accompanying drawing.

As shown in Figure 1 to Figure 3, specific embodiment of the utility model, including aeration tank 1 and electrochemical reactor, aeration Pond 1 is V-type sequential aeration device 2, and aerator 2 includes impulse generator 24 and air blower 25, and electrochemical reactor will be dirty Aqueous electrochemical catalytic oxidation treatment；

The SBBR Combined sewage process flow is as follows:

A, it is fed sequentially into coarse rack and fine fack into sewage, removes big rubbish and residue；

B, conditioning tank is entered back into, controls the pH value and water of sewage, and retain 8 hours；

C, sewage is then passed through into primary sedimentation tank, sludge settling is removed；

D, sewage is sent into V-type sequential aeration pond 1 again with intake pump, adjusts aerator 2 as staggered form aeration, adjustment exposes Tolerance optimum value is in 72~90L/h；

E, the sewage after aeration enters electrochemical reactor, is electrolysed by positive and negative anodes, is electrolysed to phenols harmful substance, Resolve into innocuous substance；

F, the sewage after electrochemical reactor is electrolysed enters back into biomembrane processing pond, with blender, number hole aerator Activated sewage processing is carried out with air pump；

G, biomembrane processing pond is equipped with sludge mouth and sludge-tank and is discharged sludge, water trap will treated sewage transport to disappearing Malicious pond；

H, it is disinfected after discharge purified water；

I, sludge is transported to soot.

Further, the V-shaped sequence arrangement in 1 pool wall of aeration tank of aerator 2, air blower 25 is against in aeration tank 1 The V-shaped blowing of sewage, using impulse generator 24 pulsed be aerated, shape be sector, bottom be equipped with slot 23, face expose Gas pond 1, such V-type intersect aeration, enhance aeration area, save 1 space of aeration tank.

Further, resistance type air bearing dustproof cover 21 is installed in the aperture of aerator 2, prevents sludge from entering device.

Further, air bearing dustproof cover is equipped with solarization air cap 22, blows out bubble and is aerated to sewage, and aeration raises gas purification effect Fruit is good.

Further, phenols electrolytics formula is MOx+H2O=MOx (OH)+H++e-=MOx (OH)=MOx+1+H ++ e- is converted to harmless substance by phenols harmful substance.

Further, the sludge of sludge-tank transports to soot by dewaterer dehydration and sludge are outer together.

Further, additive liquid chlorine, ozone, chlorine dioxide, ultraviolet light are added in sterilization pool to carry out disinfection.

Coarse rack: sewage enters coarse rack, removes large-scale pollutant；

Fine fack: sewage enters fine fack, removes small-sized pollutant；

Conditioning tank: regulating water quality water, adjustment pH value, the residence time 8 hours；

Primary sedimentation tank: sewage layering removes sinker and floating material；

Aeration tank 1: aerator 2 uses pulsed aeration, is arranged in 1 pool wall of aeration tank by V-type sequence.It is acted on It is to make activated sludge in aeration tank 1 sufficiently and waste water, has oxygenolysis to the organic pollutant in sewage.

Electrochemical reactor: the technique uses direct oxidation method, and principle is: being generated by metal oxide MOx (resistance) The high oxide MOx+1 that the aoxidizes pollutant preferably and free radical MOx (OH) for preferably making pollutant oxidizing fire, makes pollutant Noxious material is changed into innocuous substance, or the organic matter of biocompatible is converted into biocompatible substance (such as aromatic substance Ring-opening oxidation is fatty acid), further to implement biological treatment.

Reaction equation is as follows:

MOx+H2O→MOx(·OH)+H++e-

Then existing oxygen reaction on the hydroxyl free radical and anode adsorbed, and the oxygen in hydroxyl free radical is made to be transferred to gold Belong to oxide lattice, form high oxide MOx+1:

MOx(·OH)→MOx+1+H++e-

When organic matter is not present in solution, the active oxygen following steps of two states carry out oxygen evolution reaction:

MOx(·OH)→O2+MOx+H++e-

MOx+1→MOx+O2

When, there are when oxidable Organic Pollutants R, reaction is as follows in solution:

R+MOx(·OH)y→CO2+MOx+yH++e-

R+MOx+1→MOx+RO

RO is the pollutant after oxidation, nontoxic.The reactor is containing cyanide, is containing phenol, alcohol-containing, nitrogenous organic dyestuff Wastewater treatment in, direct electrochemical oxidation has all played very effective effect；

Sequencing batch biofilm reactor (SBBR) process is as follows:

The reactor one complete period is total to about 8 hours.After starting SBBR, waste water is transported to reactor by intake pump In, after water level reaches high water level electrode, self-con-tained unit stops water inlet；Blender starts to stir, and it is anti-to carry out 2 hours anaerobism It answers；Subsequent air pump is started to work, and is carried out aeration by aeration tank 1 (containing activated sludge) and is kept aeration quantity in 72~90L/h, instead Answer device denitrification effect best, TN removal rate reaches 73.4%.Flow is adjusted with spinner flowmeter, is aerated aerobic stage totally 5 hours, It is precipitated 0.5 hour after aeration, starts to drain after precipitating, stop draining when water level reaches lowest water level electrode heel row water control hydrophone, It finally leaves unused and allows within 0.5 hour activated sludge activity recovery.

SBBR technique is increased electrochemical catalytic oxidation process flow by the utility model, is handled in sewage and is difficult to containing phenols etc. The pollution factor of processing reaches optimal aeration quantity by improving aerator composition and layout.V-type aeration method greatly enhances Aeration area saves 1 space of aeration tank, meets process sewage target Scheme from the basic SBBR that solves, not only has good Good denitrogenation dephosphorizing efficiency also adds sewage treatment capacity, and realizes sewage treatment integration, and occupied area is few, can save Province part capital expenditure and operational administrative are more convenient.These features can meet Small Urban sewage treatment at this stage in skill Art and requirement economically, this method have important practical application value.
