Summary of the invention
The purpose of this utility model is the shortcoming that overcomes or improve prior art, a kind of compact construction is provided, low cost of manufacture, the waste disposal plant that treatment effect is good, the biochemical process and the Sludge Bed filtration of denitrogenation dephosphorizing are combined, technical process is simple, can resist to impact and meet, traditional mud-water separation means have particularly been changed, have mud-water separation efficient and extraordinary effluent quality more efficiently, and be easy to the integrated sewage treating apparatus that seriation and modularization are produced, not only can be used for large-scale sewage and focus on, more can be applicable to small-sized decentralized wastewater processing.
The integrated biochemistry filtered sewage disposal device of the utility model, it is characterized in that in treating pond, being provided with V-arrangement Sludge Bed strainer, V-arrangement Sludge Bed strainer is separated into treating pond double/anaerobic zone, aerobic reactor zone, between the bottom of described Sludge Bed strainer and the treating pond bottom certain interval is arranged, bottom at the Sludge Bed strainer is provided with the Sludge Bed water-in near aerobic zone one side, the bottom of V-arrangement Sludge Bed strainer is provided with mud return line, mud return line connects reflux pump, mud is back to the place suitable for reading of double oxygen/anaerobic zone, the bottom of aerobic zone is provided with aerating apparatus, the place suitable for reading of Sludge Bed strainer is provided with the water outlet overflow device, and overflow device bottom is provided with rising pipe.
Description of drawings
Fig. 1 is the synoptic diagram of an embodiment of the present utility model.
Embodiment
The integrated biochemistry filtered sewage disposal device that the utility model proposes comprises treating pond 1, the inlet that sewage enters treating pond is 12, V-arrangement Sludge Bed strainer 5 is set in treating pond, its inside is mud-water separation district 4, V-arrangement Sludge Bed strainer 5 is separated into treating pond double/anaerobic zone 2, aerobic reactor zone 3, between the bottom of V-arrangement Sludge Bed strainer and the treating pond bottom certain interval is arranged, the bottom of Sludge Bed strainer is provided with Sludge Bed water-in 6 near aerobic zone one side, the bottom of Sludge Bed strainer is provided with mud return line 7, mud return line connects reflux pump 8, mud is back to the place suitable for reading of double oxygen/anaerobic zone, the bottom of aerobic zone is provided with aerating apparatus 11, the place suitable for reading of Sludge Bed strainer is provided with water outlet overflow device 9, has rising pipe 10 under the overflow device.Below in conjunction with embodiment and accompanying drawing the utility model is described in detail.
The utility model is in practice, the sewage disposal flow process is as follows: simple pretreated sewage through inlet enter double oxygen/anaerobic zone and with the active sludge thorough mixing that refluxes from V-arrangement Sludge Bed filter bottom, behind the oxygen/anaerobic zone of holding concurrently, the gap that from the bottom is V-arrangement Sludge Bed strainer and treating pond bottom enters aerobic reactor zone, enter V-arrangement Sludge Bed strainer through the mud of aeration aerobic treatment and the mixed solution of water from the Sludge Bed water-in, biofiltration and throwing out take place in the Sludge Bed strainer, in the process of upper reaches, micropopulation increases gradually and constantly slows down until the micropopulation transfixion, forming one deck filtration medium is Sludge Bed, and separating and filtering efficient is improved greatly.After the mud-water separation, clear water enters overflow weir and discharges reactor, and active sludge then is back to double oxygen/anaerobic zone by Sludge Bed filter bottom collection tube, the Sludge Bed strainer is a upward flow, and along with the rising of current, flow velocity slows down gradually, more help mud-water separation, efficient improves greatly.
The utility model is integrated biochemistry filtered sewage disposal device, and double oxygen/anaerobic pond, aerobic reaction pond and Sludge Bed strainer are combined, and has changed the traditional wastewater biochemical treatment and has filtered the mode that is arranged of dividing.Adopt integration apparatus, and the traditional filtration means of the change of filter plant wherein, but adopt upward flow V-arrangement Sludge Bed to filter, separation efficiency is improved greatly.Be applicable to fields such as municipal wastewater, sanitary sewage, industrial sewage, not only can be used for large-scale sewage to focus on, more can be applicable to small-sized decentralized wastewater processing, as rural area, sub-district, tourist attractions etc.
Principal feature of the present utility model is embodied in the following aspects.
1, wastewater treatment efficiently not only can be removed common organism, effectively reduces BOD, COD, and has the effect of denitrogenation dephosphorizing, and the aerobic area of sludge filtration bed provides necessary condition by " nutraceutical picked-up " for denitrogenation dephosphorizing.Oxygen compatibility pool provides favourable condition as " selecting the district " for settleability and the hyphomycetic growth of control that improves mixed solution.
2, investment and running cost are low, compare with existing more advanced technology such as SBR, oxidation ditch, needed mechanical assist device, electricity needs, monitoring requirement etc. are all lower, so be that initial cost of investment or later running cost all greatly reduces.
3, moudle type flexible design, Sludge Bed strainer wherein can be used as newly-built equipment, also can reconstruct existing reaction tank, adopts multiple material to be retrofitted in the existing treating pond and uses.
4, floor space is little, and this equipment collection is nitrated, denitrogenation, precipitation and to stablize the mud process be one, has reduced the requirement to connecting between the equipment, has dwindled the floor space of whole plant.
The utility model is determined by experiment, the optimum operation controlled variable of handling municipal wastewater is as follows: oxygen-starved area DO＜0.1mg/L, aerobic zone DO is at 2.0～4.0mg/L, PH should remain on 7.0-8.5, return sludge ratio R=200%, total HRT=8h(aerobic zone 6h, oxygen-starved area 2h), SRT=15d.At this moment, COD on average goes out water concentration below 50mg/L, and ammonia nitrogen approaches 0mg/L, and TN is about 5mg/L, and TP is below 0.5mg/L, and effluent quality reaches (GB18918-2002) one-level category-A standard of country's " urban wastewater treatment firm pollutant emission standard ".COD, ammonia nitrogen and TP average removal rate are all more than 90%.Because the biofiltration and the throwing out of V-arrangement upward flow sludge filtration bed, water outlet is very limpid, and near tap water, SS is almost nil, NTU=2～3.
