Processing method.
Background technology
In recent years, the living standards of the people of rural area are continuously improved, and water consumption increases year by year, while increasing rural area dirt
The discharge capacity of water.The water quality of country sewage is close with city domestic sewage, and the pollutant concentrations such as organic matter, nitrogen, phosphorus are higher.By
In in rural area, sewage disposal small scale, peasant household, which lives, more to be disperseed, and sewage collecting is difficult, it is difficult to extensive centralized processing,
It is suitble to using the unattended integrated sewage treating apparatus for handling small-scale sanitary sewage.
Currently, to the research of rural sewage treatment process tend to diversification, but mainly including the use of soil as collect and
At the natural ecological treatment system of discharge carrier, conventional treatment systems and small-scale sewage using complicated biology and physical process
Manage device.Natural ecological treatment system such as artificial swamp, floor space is excessive, and investment cost is high, and complex management, outlet effect is not
People's will to the greatest extent；Common traditional life sewage treatment process such as anaerobic- anoxic- oxic activated sludge process, activated sludge usually occur
Abnormal or sludge bulking or sludge decomposition, it is therefore desirable to Attended mode, to be taken in time for activated sludge abnormal conditions
Counter-measure；Although Small Sewage Treatment Equipment such as membrane bioreactor realize the integration in structure, but plant investment compared with
Height, operation power consumption are larger.
Therefore, for country sewage feature and complex management of the existing technology, investment operating cost, high, processing is imitated
The disadvantage of fruit difference, need to seek it is a kind of can unattended, country sewage integrated treatment that investment operating cost is low, energy-efficient
Equipment.

Hypoxic-ischemic brain-damage 1-3, organics removal and bulky grain suspended matter；Third level hypoxic-ischemic brain-damage 1-3 is discharged from bottom water distribution
9 upward uniform water distribution of captation enters 2 suspension haydite filter bed 6 of flow-raising aeration biological filtering pool, and compressed air is through aeration and biological
2 distribution device 8 of filter tank enters suspension haydite filter bed 2 and is aerated, and remaining organic matter in nitrification ammonia nitrogen and degradation sewage flows up out
Water reaches top water distribution gathering ground 4；A part of effluent recycling of 2 water distribution gathering ground 4 of flow-raising aeration biological filtering pool is to the first order
Hypoxic-ischemic brain-damage 1-1 water distributions gathering ground 4, mixes with raw sewage, carries out denitrification denitrogenation, and another part water outlet, which then enters, catchments
Water outlet is aerated by canal 2-1, compressed air through being aerated mixing tube 15, to be sufficiently mixed carry out coagulation with the medicament added；By
Water outlet after coagulation enters 3 settling zone 3-1 of inclined-plate clarifying basin and is precipitated, to further remove dephosphorization, suspended matter and organic matter,
Up-flow water outlet, which is entered by inclined plate 3-2 behind water distributing area 4 of catchmenting, is collected to the water outlet of outlet pipe 16, is deposited to sludge in sludge bucket 3-4
It is discharged by sludge pipe 17.
1 interval of deflector type hypoxic-ischemic brain-damage carries out backwash and restores its filtering cloth head for a period of time, uses
Combined water and air backwash.When being backwashed to first order hypoxic-ischemic brain-damage 1-1, equipment stopping adds flocculant five minutes
Stop water inlet afterwards, opens the electrically operated valve 22 of the bottoms first order hypoxic-ischemic brain-damage 1-1 gas-distribution pipe 12, compressed air is through gas-distribution pipe
12 flow to the bottoms first order hypoxic-ischemic brain-damage 1-1 distribution device 8, and carrying out uniform aeration to filter tank increases suspension haydite filter bed 6
Degrees of expansion is fluidized, biomembrane is fallen off and impurity sinks to bottom, aeration opens backwash pump 18 by outlet canal 2-1 after five minutes
First order hypoxic-ischemic brain-damage 1-1 water distributions gathering ground 4 is squeezed by backwashing water inlet pipe 14 compared with clean water, flows into suspension haydite
Filter bed 6 carries out air water combined cleaning, opens simultaneously bottom by outside the sewage discharge pond containing impurity, backwash is closed after ten minutes
Water pump 18 simultaneously stops being aerated and drain, and restores water inlet and dosing, to complete the recoil to first order hypoxic-ischemic brain-damage 1-1
It washes.Second level hypoxic-ischemic brain-damage 1-2 and third level hypoxic-ischemic brain-damage 1-3 are backwashed using same procedure.Up-flow
