Described circulation device comprises a high pressure positive blower, connecting tube and aeration tube, and the input terminus of described high pressure positive blower is communicated with reactor top by connecting tube, and output terminal is communicated with aeration tube, and aeration tube is arranged on reactor lower part.
The present invention also comprises a control device, whether this control device comprises data handler, be arranged on reactor internal upper part oxygen probe and pressure probe, carry out Treatment Analysis to work to exhaust orifice open/close and apparatus of oxygen supply control by the data of data handler to oxygen probe and pressure probe collection.
Vacuum breaker is provided with between described apparatus of oxygen supply output terminal and inlet mouth.
The invention has the beneficial effects as follows: adopt the present invention of said structure by arranging an airtight reactor, and constantly for providing oxygen in reactor, and circulation device is set in reactor, can be the reaction of inner aerobic biochemical and sufficient oxygen is provided, improve aerobic biochemical reaction mass, perfectly can realize activated sludge process.The present invention is simple and practical, Be very effective.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is principle schematic of the present invention.
Embodiment
With reference to Fig. 1, the present invention is a kind of oxygen-enriched aeration system, comprise a reactor 1, control device and an apparatus of oxygen supply 2, apparatus of oxygen supply adopts oxygen cylinder oxygen supply, this reactor 1 inner hollow, reactor 1 is arranged inlet mouth 3, venting port 4, inlet channel 5, outlet conduit 6 and spoil disposal pipeline 7, apparatus of oxygen supply 2 output terminal is connected with inlet mouth 3, being provided with vacuum breaker 8 between apparatus of oxygen supply 2 output terminal and inlet mouth 3, being also provided with one in reactor 1 for the gas on reactor 1 top being delivered to the circulation device of reactor 1 bottom; Whether control device comprises data handler, is arranged on reactor 1 internal upper part oxygen probe 9 and pressure probe 10, carry out Treatment Analysis to work to venting port 4 opening and closing and apparatus of oxygen supply 2 control by data handler to the data that oxygen probe 9 and pressure probe 10 gather.Before operation, active sludge is placed in reactor 1 bottom (can place filler according to sewage quality situation and processing requirements in active sludge, magnetic etc.), microorganism and treatment sewage, sewage pumps into from inlet channel 5, mix in reactor 1, aeration, after microbiological deterioration in active sludge, staticly settle, after degraded, water flows out from rising pipe, aged mud jack-up is got rid of from spoil disposal pipeline 7, in operational process, liquid level is not full of reactor 1 inside, the headspace of reactor 1 is gas, control reactor 1 inner top by control device and maintain pressure constant state, Real-Time Monitoring oxygen content simultaneously, when oxygen content is lower than set(ting)value, start apparatus of oxygen supply 2 oxygen supply, open venting port 4 to be exhausted when the headspace pressure of reactor 1 is too large.Adopt the present invention of said structure by arranging an airtight reactor 1, and constantly for providing oxygen in reactor 1, and circulation device is set in reactor 1, can be the reaction of inner aerobic biochemical and sufficient oxygen is provided, improve aerobic biochemical reaction efficiency and aerobic biochemical reaction quality, perfectly can realize activated sludge process.The present invention is simple and practical, Be very effective.
As shown in the figure, circulation device can adopt following embodiment, comprises a high pressure positive blower 11, connecting tube 12 and aeration tube 13, and the input terminus of high pressure positive blower 11 is communicated with reactor 1 top by connecting tube 12, output terminal is communicated with aeration tube 13, and aeration tube 13 is arranged on reactor 1 bottom.The oxygen at reactor 1 top pumps into bottom through high pressure positive blower 11, oxygen enters aqueous phase through bottom aeration tube 13, and partial oxidation is utilized by the biosolubilization in active sludge in aqueous phase, can improve the rate of consumption of oxygen, acceleration aerobic biochemical reacts, and improves aerobic biochemical speed of response and quality.
Above-described embodiment is preferred version of the present invention, and the present invention also can have other embodiments.Those skilled in the art also can make equivalent variations or replacement under the prerequisite without prejudice to spirit of the present invention, and these equivalent modification or replacement are all included in the scope set by the application's claim.
