Abstract
The utility model discloses a microporous aeration backwashing device for a sewage treatment aeration tank, which comprises a sewage aeration tank, an aerator pipe, a compressed air inlet pipe, a high-pressure backwashing water inlet pipe and an eduction pipe. The compressed air inlet pipe is communicated with the inside of the aerator pipe. The aerator pipe is provided with a plurality of micropores. The high-pressure backwashing water inlet pipe is communicated with one end of the aerator pipe. The eduction pipe is communicated with the other end of the aerator pipe. The high-pressure backwashing water inlet pipe and the eduction pipe are respectively provided with valves. When precipitates are higher than the micropores of the aerator pipe, a valve on the compressed air inlet pipe is closed, the valve on the eduction pipe is opened, the valve on the high-pressure backwashing water inlet pipe is opened, high-pressure backwashing water is started to wash away the precipitates in the aerator pipe, the high-pressure backwashing water is stopped, the valve on the eduction pipe is closed, the backwashing high-pressure water is started again, and at this time, the high-pressure water can be discharged through the micropores, so that the purpose of backwashing the microporous aerator pipe is fulfilled. Due to the adoption of the device, the micropores of the aerator pipe are avoided being blocked by the precipitates and the water treatment capability is improved.
Description
Technical field
The utility model relates to a kind of back-purge system, relates in particular to a kind of aeration in sewage treatment pond micro-pore aeration back-purge system.
Background technology
Cold rolling mill is when handling pickling-rinsing waste water, and the method by acid-base neutralisation normally adds the milk of lime or the sheet alkali of alkalescence to the sour water in the rinse water, feeds flocculation sediment behind the abundant aeration of pressurized air again, and the clear water after up to standard discharges.When neutralization reaction, because pickling composition in the poaching wastewater and milk of lime alkaline components neutralization reaction generate salt and water.Chemical equation: HCl+NaOH=NaCl+H
2O, 2HCL+Ca(OH)
2=CaCl+2H
2O.In the rinse water micro-ferric oxide, ferric oxide and titanium dioxide three-iron behind abundant aeration redox Cheng Tieyu acid-base neutralisation salt and the mud sediment in the milk of lime, reach the micropore height of aeration tube when precipitation capacity after, these throw outs are with the micropore of blocking aeration pipe, influence the aeration effect, prolong the treatment time, thereby reduced water treatment capacity.
The utility model content
At the prior art above shortcomings, the utility model provides a kind of micropore of avoiding throw out blocking aeration pipe, improves the aeration in sewage treatment pond micro-pore aeration back-purge system of water treatment capacity.
The aeration in sewage treatment pond micro-pore aeration back-purge system that the utility model provides, comprise the sewage aeration pond, be arranged on aeration tube, compressed air inlet pipe, high pressure back flushing water inlet pipe and waste pipe in the sewage aeration pond, described compressed air inlet pipe is communicated with aeration tube is interior, described aeration tube is provided with a plurality of micropores, described high pressure back flushing water inlet pipe is communicated with an end of aeration tube, waste pipe is communicated with the other end of aeration tube, on described high pressure back flushing water inlet pipe and the waste pipe valve is set respectively.
Further, on described high pressure back flushing water inlet pipe and the waste pipe check valve is set respectively also.
The beneficial effects of the utility model: be higher than the micropore of aeration tube when throw out after, valve on the closes compression air intake duct is opened the valve on the waste pipe, opens the valve on the high pressure back flushing water inlet pipe, start the high pressure backwashing water, throw out in the aeration tube is rinsed out, stop the high pressure backwashing water, close the valve on the waste pipe, start backwash high pressure water once more, at this moment, high pressure water can outwards release by micropore, thereby reaches the purpose of back flushing micropore aeration pipe.This device is avoided the micropore of throw out blocking aeration pipe, improves water treatment capacity.
Description of drawings
Fig. 1 is the structural representation of aeration in sewage treatment pond micro-pore aeration back-purge system.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
Fig. 1 is the structural representation of aeration in sewage treatment pond micro-pore aeration back-purge system, as shown in the figure.Aeration in sewage treatment pond micro-pore aeration back-purge system comprises sewage aeration pond 1, is arranged on aeration tube 2, compressed air inlet pipe 3, high pressure back flushing water inlet pipe 5 and waste pipe 6 in the sewage aeration pond 1.Compressed air inlet pipe 3 and 2 interior connections of aeration tube, aeration tube 2 is provided with a plurality of micropores 4, and high pressure back flushing water inlet pipe 5 is communicated with an end of aeration tube 2, and waste pipe 6 is communicated with the other end of aeration tube 2; On high pressure back flushing water inlet pipe 5 and the waste pipe 6 valve 7 is set respectively.
Throw out in aeration tube 2 flows backwards, and check valve 8 also is set respectively on high pressure back flushing water inlet pipe 5 and waste pipe 6.
Be higher than the micropore 4 of aeration tube 2 when throw out after, valve on the closes compression air intake duct 3 is opened the valve 7 on the waste pipe 6, opens the valve 7 on the high pressure back flushing water inlet pipe 5, start the high pressure backwashing water, throw out in the aeration tube 2 is rinsed out, stop the high pressure backwashing water, close the valve 7 on the waste pipe 6, start backwash high pressure water once more, at this moment, high pressure water can outwards release by micropore 4, thereby reaches the purpose of back flushing micropore aeration pipe.This device is avoided the micropore of throw out blocking aeration pipe, improves water treatment capacity.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
