Abstract
The utility model relates to highway ancillary facility sewage treatment equipment for promoting ammonia nitrogen up-to-standard emission. The highway ancillary facility sewage treatment scale is generally designed according to predicted traffic in a design document; but the actual situation is that the predicted traffic cannot be achieved substantially in the first several years after a highway is opened to traffic; and thus, the present situation of large model of the selected equipment is caused, and poor sewage treatment effect is caused. The highway ancillary facility sewage treatment equipment is sequentially provided with an oil separation tank, a grille, an adjusting tank, a biological contact oxidation tank, a secondary sedimentation tank and a sterilization tank which are connected through a sewage pipe, wherein a water outlet of the sterilization tank is provided with an ammonia nitrogen on-line monitor; and a sewage pump is arranged in the secondary sedimentation tank and is connected with the biological contact oxidation tank through a reflow sewage pipe. According to the highway ancillary facility sewage treatment equipment, the sewage treatment cost is greatly reduced, the contradiction that the water quantity of the equipment at the initial stage of operation of the highway is small and the water quantity at the middle and later stages is increased is relieved, whether the ammonia nitrogen is up to standard is judged on line, and reflow retreatment is performed to realize up-to-standard emission.
Description
Technical field
The utility model relates to a kind of sewage disposal device, is specifically related to a kind of motorway affiliated facility sewage disposal device that promotes the ammonia nitrogen qualified discharge.
Background technology
At present, domestic more buried integrated sewage treating apparatus is made up of preliminary sedimentation tank, equalizing tank, A level biological tank, O level biological tank, second pond, sludge sump and sterilization pool.Sewage is at first removed bigger PM for particulate matter through preliminary sedimentation tank, and the back gets into equalizing tank and carries out the water quality and quantity adjusting, wherein establishes sump pump in the equalizing tank; Sewage is promoted to A level biological tank, O level biological tank in the integrated apparatus; Sewage is accomplished main organic matter removal task through the gas blower aeration in these two ponds, the back gets into second pond, in this mud-water separation; Supernatant effluxes after flowing into the sterilization pool sterilization, and the sludge part that precipitates is back to equalizing tank and participates in work of treatment again.General sewage disposal device type selecting does not often match with the actual sewage amount utmost point, and aeration is 24 hour operation in 24 hours then, causes running cost higher, and the water outlet ammonia nitrogen removal frank is not high, and can't judge that can water outlet reach corresponding emission standard.
Motorway affiliated facility WWT scale generally designs according to the prognosis traffic volume in the design document, but practical situation are just to be open to traffic to reach the volume of traffic of expectation in several years at all, and this has just caused equipment choosing model present situation bigger than normal.So, be open to traffic the back water yield and the lectotype selection utmost point do not match, and cause wastewater treatment efficiency not good, even can not be up to standard.And the most ammonia nitrogen removal effect of buried sewage treatment equipment on the home market is bad at present.
Summary of the invention
The purpose of the utility model provides a kind ofly to be alleviated contradiction that less and middle and later periods of initial operating stage water yield water yield increases, can onlinely judge the whether motorway affiliated facility sewage disposal device of the promotion ammonia nitrogen qualified discharge that refluxes or discharge up to standard of water outlet ammonia nitrogen.
The technical scheme that the utility model adopted is:
Promote the motorway affiliated facility sewage disposal device of ammonia nitrogen qualified discharge, be disposed with the oil trap, grid, equalizing tank, biological contact oxidation pond, second pond and the sterilization pool that are connected through waste pipe, it is characterized in that:
The water outlet of described sterilization pool is provided with ammonia nitrogen on-line monitoring appearance;
In the described second pond sump pump is set, is connected with biological contact oxidation pond through the backflow waste pipe.
Described second pond is connected with sludge sump through sludge pipe.
Be provided with submersible pump in the described equalizing tank sewage is promoted to biological contact oxidation pond.
Be provided with aeration tube in described equalizing tank, biological contact oxidation pond and the sludge sump, be connected with blower fan on the aeration tube.
Described sludge sump is provided with mud return line, is connected with biological contact oxidation pond.
The utlity model has following advantage:
The utility model can significantly reduce WWT running cost; The contradiction that alleviation equipment is less in the motorway initial operating stage water yield, the middle and later periods water yield increases effectively improves wastewater treatment efficiency, and can onlinely judge whether the water outlet ammonia nitrogen is up to standard; Reflux and handle again, accomplish qualified discharge.

Embodiment
Below in conjunction with embodiment the utility model is carried out detailed explanation.
The motorway affiliated facility sewage disposal device of the described promotion ammonia nitrogen of the utility model qualified discharge; Be disposed with the oil trap 1, grid 2, equalizing tank 3, biological contact oxidation pond 4, second pond 5 and the sterilization pool 7 that are connected through waste pipe 11, second pond 5 is connected with sludge sump 6 through sludge pipe 13.The water outlet of sterilization pool 7 is provided with ammonia nitrogen on-line monitoring appearance 8.In the second pond 5 sump pump is set, is connected with biological contact oxidation pond 4 through backflow waste pipe 11.Be provided with submersible pump 10 in the equalizing tank 3 sewage is promoted to biological contact oxidation pond 4.Be provided with aeration tube 12 in equalizing tank 3, biological contact oxidation pond 4 and the sludge sump 6, be connected with blower fan 9 on the aeration tube 12.Sludge sump 6 is provided with mud return line 13, is connected with biological contact oxidation pond 4.
Sewage gets into oil trap 1 through waste pipe 11; Vegetable and animals oils in the removal motorway affiliated facility sewage and the petroleum-type in the carwash sewage etc.; Remove back entering equalizing tanks 3 such as larger particles and hair through grid 2, carry out the adjusting of water quality, the water yield at this, the back is promoted to integrated apparatus by submersible pump 10---biological contact oxidation pond 4; Sewage is degraded in this pond and is removed the organic pollution materials of the overwhelming majority; Afterwards from flowing to second pond 5, carry out after the mud-water separation supernatant and drain into sterilization pool 7 and carry out disinfection, the mud that precipitates gets into sludge sump 6 and handles; Mud part after the processing is back to biological contact oxidation pond through sludge pipe 13, part discharging.The water outlet of post precipitation replenishes water inlet in the less situation refluxed of affiliated facility water displacement in early stage, has so promptly solved the problem of the initial stage water shortage that is open to traffic, and has also improved the ammonia nitrogen removal frank of equipment; Under the bigger situation of the water yield, flow to ammonia nitrogen on-line monitoring appearance 8 and carry out monitoring water quality on line and judge,, then be not back to biological contact oxidation pond 4 and handle again through analysis and judgement as the ammonia nitrogen index is up to standard when the then discharging all up to standard of ammonia nitrogen index.
