Slightly, fine fack enters conditioning tank 12, and then sewage is entered by conditioning tank such as any right of claim 1-7 by elevator pump 9
It is required that the processing device system that the domestic sewage in rural areas is integrated, heavy by the first processing pond 1, second processing pond 2, inclined tube
It is discharged after shallow lake pond 3, the processing of ultraviolet-sterilization sterilization pool 4, wherein 3 base sludge of the inclined-tube sedimentation tank is emitted into underground by static pressure
Sludge-tank, outward transport processing or compost after the regular medicament disinfecting of sludge in sludge-tank.
First processing pond 1 controls a small amount of aeration by valve, and the second processing pond 2 is normally aerated.
When DO value is higher than 4.5 or temperature is lower than 20 DEG C, PLC turns 5 air quantity of air blower down automatically, when DO value is lower than 1.5
Or temperature be higher than 35 DEG C when, PLC tunes up the air quantity of air blower 5 automatically；When pH exceeds 6.5-8.5 range, elevator pump pump stops
It only runs and alarms, administrative staff is reminded to check reason；When liquid level is more than setting high liquid level value, elevator pump pump is automatically stopped fortune
It goes and alarms；When liquid level is lower than setting low liquid level value, PlC controls elevator pump and automatically turns on operation and warning reminding administrator
Member.
Embodiment 1
Certain rural area is originally without effective sewage treatment facility, and river water quality is poor in village, and the water bodys stink such as neighbouring ditch is serious,
Severe water pollution.By sample detection, COD value about 210mg/L, total phosphorus 5.5mg/L, total nitrogen 60mg/L in village's sewage, ammonia
Nitrogen 48mg/L.Using apparatus of the present invention system, descending conditioning tank and sludge-tank to build into a set of day output in combination is 80 tons
Sewage Disposal.The sanitary sewage in the village is collected first after septic tank by pipe network, and conditioning tank is entered after thick, fine fack,
Regulating pondage water quality, then sewage is promoted to apparatus of the present invention system by conditioning tank by elevator pump, in present apparatus system
Sterilized except pollutants such as COD, ammonia nitrogen, total phosphorus, and through ultraviolet disinfection, apparatus system treated water outlet COD index be down to 48mg/
L, total phosphorus 0.01mg/L, total nitrogen 12mg/L, ammonia nitrogen 4.5mg/L, effluent quality are obviously improved, being capable of qualified discharge.Sedimentation basin bottom
Portion's sludge is emitted into underground sludge-tank by static pressure, transports outward processing or compost in sludge-tank after the regular medicament disinfecting of sludge.
The problem of very good solution of the present invention rural area sewage quantity is small, residential area dispersion, lacks construction O&M fund,
A kind of sewage-treatment plant system that effect is good, at low cost, integrated is provided.Apparatus of the present invention internal system is confined air
Between, peculiar smell does not dissipate in treatment process, good sewage processing effect, and investment, operating cost are low, and high degree of automation can be supervised remotely
Control operation operation.
Although the present invention has been described by way of example and in terms of the preferred embodiments, they be not it is for the purpose of limiting the invention, it is any ripe
This those skilled in the art is practised, without departing from the spirit and scope of the invention, can make various changes or retouch from working as, therefore guarantor of the invention
Shield range should be subject to what claims hereof protection scope was defined.
