Technical field
The utility model relates to the processing units of domestic sewage in rural areas.
Background technique
With the development of economy, while China rural area living standards of the people improve, living-pattern preservation, agriculture are brought
Requirement of the village people to quality of life is higher and higher, so that the yield of sanitary sewage is also higher and higher.Due to life in the countryside dirt
The governing system of water is not perfect, sewage discharge and collect it is most of be directly discharged into the form of open channel or underdrain into rivers or
It permeates the ground with rainwater, the underground drinking-water of polluted river water source and resident.
Drinking water in rural China in addition to life wash one's face and rinse one's mouth with wash water other than, further include sanitary wastewater and other mixing class sewage,
Such as: sewage caused by the brings such as rural area aquaculture and poultry farming sewage, farming etc..Since population one is gathered in rural area
As scale in 500-3000 people, sewage day, yield was at 20-500 tons or so, it is difficult to focus on.Water relatively concentrate on it is early,
In, late cooking time section, the sewage of these three periods discharge is 2~3 times of usually quantity of wastewater effluent, and water changes greatly.
The construction of Rural water supply pumping equipment and operation cost are high, and shortage of funding is a great problem for hindering Rural Water Pollution to administer.It is existing
Oxidation pump needed for device using anoxic-aerobic process processing domestic sewage in rural areas is more, and equipment cost is high, energy consumption height when operation,
It comes into operation in the rural area for being not suitable for many shortages of funding.

Water hole；
Aerobic tank is divided into two parts by setting partition among aerobic tank, and the bottom of partition is equipped with the second water hole；Close
Setting return pipe is back in the water inlet of anoxic pond in the aerobic tank of sedimentation basin side；
Third water hole is set in the middle part of the partition between aerobic tank and sedimentation basin；It is provided in the side wall upper part of sedimentation basin
The mouth of a river；
Abacus is set in the bottom of anoxic pond and aerobic tank, filler is loaded on orifice plate；
Water tank inlet is connected by the water inlet of water pump and anoxic pond with pipeline；
The aeration head connecting with aeration pump is arranged in below the orifice plate of the bottom of aerobic tank.
The principle and application method of the rural domestic sewage treating device of the utility model:
One, start:
(1) domestic sewage in rural areas is added in water tank inlet, and is delivered in anoxic pond with water pump and flows into aerobic tank
In sedimentation basin, water level is made to reach the 50%~70% of anoxic pond height；Sewage treatment plant is taken to contain nitrobacteria and denitrification
The sludge of bacterium, is added in anoxic pond and aerobic tank, and sludge concentration is made to reach 300~500mg/L；Starting aeration pump makes aerobic
Area's dissolved oxygen reaches 2~3mg/L；Controlling mixed liquid recycle ratio is 300%；It cultivates, stops after 5 days, in discharge with this condition
Clear liquid completes the culture of a cycle；Then domestic sewage in rural areas is rejoined, is cultivated under conditions of a cycle,
Incubation time successively successively decreases 1 day by each period, until incubation time reduces to 1 day；Microorganism is attached on filler to grow；
(2) it is continuously injected into domestic sewage in rural areas again, makes hydraulic detention time 18 of the sewage in anoxic pond and aerobic tank
Hour, after operation 1 day, gradually by anoxic pond and the hydraulic detention time in aerobic tank shorten to 14~15 hours, it is 10~12 small
When, 8~9 hours, after being discharged COD, ammonia nitrogen, total nitrogen, total phosphorus stabilizer, startup stage terminates；
Two, stable operation:
Domestic sewage in rural areas is continuously added in water tank inlet, by temperature in water tank inlet is 20~25 DEG C by water pump
Sewage, which is input in anoxic pond, carries out Anaerobic Treatment, hydraulic detention time 4h, and treated, and water is flow to by the first water hole
In aerobic tank；Aerobic tank is aerated through aeration head with aeration pump, the dissolved oxygen content in aerobic tank is 2~3mg/L, and waste water is good
Hydraulic detention time in oxygen pond is 5h, controls mixed liquid recycle ratio 200%~300%；Treated water is through third water hole
It is flowed into sedimentation basin, aluminium polychloride (PAC) 15~20mg/L of dosage in sedimentation basin, the supernatant water after precipitating is through top
Water outlet outflow, completes wastewater treatment.
The device of the utility model compared with the prior device, has the following advantages:
1) it is at low cost: since the device can be by sludge fermentation at organic matter, using the organic matter of degradation as denitrifying
Carbon source, therefore do not need additional carbon, Treatment of Sludge.Aerobic zone only needs an oxidation pump, does not need sludge reflux pump, also not
Nitrification liquid reflux pump is needed, installation cost is low, and energy-consuming consumptive material takes also low when operation, solves rural domestic sewage treating device fortune
Seek problem at high cost.
2) strong shock resistance: the fluctuation of domestic sewage in rural areas water quality and quantity is big, takes to add anoxic zone and aerobic zone and fill out
The impact resistance of the technique can be improved in the method for material.
3) effluent quality is good: the anoxic zone residence time is long, and denitrification is thorough, while the sludge generated is detested in anoxic zone bottom
Aerobe fermentation forms organic matter, further increases denitrification effect, removes total nitrogen effect than general rural domestic sewage treating device
More preferably, removal rate is up to 68.72%.
