Technical field
The utility model relates to a kind of domestic sewage processing system, especially a kind of samll cities and towns that are suitable for carry out sewage treatment
Domestic sewage processing system, belong to the innovative technology of domestic sewage processing system.
Background technique
In recent years, the urbanization in China is continuously improved with economic development, along with the quickening and economy of Development of China's Urbanization
Continuous development, the water environment of samll cities and towns is also faced with serious pollution.In order to avoid walking the old road of " first polluting, rear to administer ",
Cooperate the completion of China's strategy of sustainable development, we will develop the sewage treatment work of economical rationality, suitable Small Urban
Skill, ensure urban population water resource normal use, while by sewage treatment arrive meet country discharge standard.
Currently, town sewage has become one of the main reason for China's regionality water pollution, this living environment to us
Cause serious influence, domestic most of sewage treatment project built at present concentrates on city or county town, therefore samll cities and towns
Waste water control is a new strategic objective of the country behind big and medium-sized cities, but because of Small Town Wastewater collection mode with shut off for
Main, rainy season sewage silt content is big, and the limitation of the factors such as samll cities and towns' treatment facility small scale, at high cost, and domestic main concentrate is ground
Study carefully the sewage treatment process of big and medium-sized cities.It is suitble to the technique of processing small town sewage, and biochemical treatment is integrated
The design in pond rarely has specific instance analysis.With the attention of Environmental problem, and the promotion to low-carbon life, small city
It is few that town sewage treatment needs a set of investment operating cost, and effluent quality can be up to < <urban wastewater treatment firm pollutant emission standard
(GB18918-2002) > > level-one A standard treatment process.
Since the search time that China is dedicated to Small Town Wastewater treatment process is shorter, and mainly, research is setting for monomer
Meter and the design of integrated A AO etc., how the feature small according to Small Town Wastewater water quality and treatment scale, design a set of land occupation and advise
Mould is small, investment operating cost is few, effluent quality can reach<<urban wastewater treatment firm pollutant emission standard (GB18918-2002)>
The treatment process of > level-one A standard is the problem of each sewage disposal technology personnel are worth thinking.
Summary of the invention
The purpose of this utility model is that considering the above problem and providing a kind of domestic sewage processing system.The utility model
Land occupation small scale, investment operating cost are few, effluent quality can reach < <urban wastewater treatment firm pollutant emission standard (GB18918-
2002) > > level-one A standard.
The technical solution of the utility model is as follows: the domestic sewage processing system of the utility model, includes adjusting sand setting
Pond, anaerobic pond, anoxic pond, the first aerobic tank, the second aerobic tank, sedimentation basin, filtering cloth filtering pool, storage basin, sludge concentration tank, life
Sewage enters adjusting setting pot by water inlet pipe, adjusts the anaerobic pond that the sewage in setting pot is transported to next door by suction pump

It sets, is communicated between two ponds by the second through-hole, the first aerobic tank is disposed adjacent with the second aerobic tank, by the between two ponds
Three through-holes communicate, and the sewage in the second aerobic tank is entered in sedimentation basin by fourth hole, and the top of sedimentation basin, which is equipped with, to be made in pond
Supernatant enter the fifth hole of filtering cloth filtering pool, treated in filtering cloth filtering pool filtered fluid flows into tubular type by the 8th through-hole
Sterilizer, sewage is finally discharged through outlet pipe after disinfection.
The utility model adjusts setting pot and is combined into one conditioning tank and setting pot, and the water for adjusting setting pot passes through suction pump
Be transported in anaerobic pond, between anaerobic pond and anoxic pond, between anoxic pond and aerobic tank and between two aerobic tanks, it is aerobic
It is all connected by through-hole between pond and sedimentation basin, between sedimentation basin and filtering cloth filtering pool, between sewage successively passes through, is entered next
In a pond；Sewage in aerobic tank is flowed back into anoxic pond by interior reflux pump；Sludge in sedimentation basin by sludge pipe into
Enter into storage basin, the sludge in storage basin is flowed back into anaerobic pond and sludge concentration tank respectively by sludge pump, and sludge is dense
The sludge in contracting pond is further processed by sludge dewatering vehicle.The utility model realizes the denitrogenation dephosphorizing of sanitary sewage, removes
Organic matter and suspended matter in water and other impurities, filter tank water outlet are directly over tubular type ultraviolet sterilizer and carry out disinfection, thus
Reach level-one emission standard A.In addition, the utility model, which is adjusted in setting pot, is added to air-lift device, it is used for sand discharge, is reduced artificial
The danger of sand discharge.Each processing unit, which is fully integrated integrated pond type, can reduce head loss between each monomer, and
Complicated pipeline is laid with, and is easy to manage concentratedly, is reduced investment operation expense；Meanwhile each monomer is integrated, reduces land occupation
Area；AAO method (anaerobic- anoxic- oxic method) and filtering cloth filtering pool, further denitrogenation dephosphorizing are used simultaneously, and removal organic matter suspends
Object etc. improves effluent quality.
