Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
The rural waste disposal plant with multi-functional baffling shown in Fig. 1-2 comprises submersible sewage pump 1 and processing unit.In this example, the whole outer profile size of described rural waste disposal plant is length * wide * height: 7.15m * 2.4m * 2.4m.It is made up of the processing unit of sizes such as 6.Its designing treatment ability is: standard load: 24m3/d, design maximum load: 48m3/d.It is to remove COD (Chemical Oxygen Demand chemical oxygen demand (COD)), BOD (Biochemical Oxygen Demand biochemical oxygen demand (BOD)), ammonia nitrogen and suspended substance that this treatment unit mainly acts on.Processing unit in turn comprises three anaerobic unit, two aerobic units and a precipitation unit by water inlet direction 3 to water outlet direction 8 according to the drainage flow direction, and adjacent processing unit connects by duct segments.In order to prolong the treatment time of sewage, described pipeline adopts baffling pipe 21 in this example.
1. anaerobic unit, 13, No. 2 ponds 14, No. 1 pond and No. 3 ponds 15 are anaerobic unit.13, No. 2 ponds 14, No. 1 pond and No. 3 ponds 15 are connected to venting hole 4 by vapor pipe 5.Submersible sewage pump 1 connects No. 1 pond 13 by reverse checkvalve 20, water inlet gate valve 19 through waste pipe 2.Be provided with three-phase sparger 23 in No. 3 ponds 15.
Anaerobic unit can be grown in separately the control environment acid-producing bacteria and methanogen respectively, help the degraded of pollutent, wherein anaerobism Unit the 1st promptly has the water quality regulation function concurrently in No. 1 pond 13, gas, solid, liquid three phase separation can be realized in Unit the 3rd i.e. triphase separator in No. 3 ponds 15, reduce sludge loss.
Place the granule sludge that has anerobe in the anaerobic unit, the organism in the sewage is carried out anaerobic oxidation.The anaerobic biological treatment method is to utilize facultative anaerobe and obligatory anaerobic bacteria that larger molecular organics in the sewage is degraded to low molecular compound, and then is converted into the organic wastewater treatment of methane, carbonic acid gas, is divided into two stages of acid digestion and alkaline digest.In the acid digestion stage.By the effect of acid-producing bacteria excretory exoenzyme, make larger molecular organics become simple organic acid and alcohols, aldehydes ammonia, carbonic acid gas etc.; In the alkaline digest stage, the meta-bolites of acid digestion further resolves into the biogas that methane, carbonic acid gas etc. constitute under the methanogen effect.This treatment process is mainly used in processing such as the organic waste water of high density and fecal sewages.
2. aerobic unit, No. 4 ponds 16 and No. 5 ponds 17 are aerobic unit.

Aerobic unit has following characteristics:
1, because packing specific area is big, and aerobic condition is good in the pond, and the biosolids amount of unit volume is higher in the pond, therefore, biological contact oxidation pond has higher volumetric loading;
2, owing to biosolids amount in the living pond is many, current mix fully, so the cataclysm of water quality and quantity is had stronger adaptive faculty;
3, surplus sludge volume is few, does not have the sludge bulking problem, and operational management is easy.
3. settling tank, i.e. No. 6 ponds 18.
For reoxygenation and the suspended substance precipitation that helps water, to reduce suspended substance to the unitary impact of subsequent disposal, the baffling pipe 21 that stretches in described No. 6 ponds 18 is water spraying pipe 31, and the port of water spraying pipe 31 is horn-like.Water spraying pipe 31 is to be made by pyramid type iron sheet 29, is installed in No. 6 ponds 18 by water spraying pipe carriage 30.The water of discharging from 17 aerobic oxidation ponds, No. 5 ponds by the trumpet type water spraying pipe 31 in No. 6 ponds 18 of precipitation dispensing, disperses the water impact of current, further precipitates the mud in the sewage.
Shown in Fig. 1-2, the discharge of mud for convenience, each processing unit is provided with mudhole 22 near the place, bottom, and mudhole 22 connects mud discharging arm 11 by spoil disposal gate valve 12 and is finally discharged by mud discharging house steward 10.
Operational process of the present utility model, shown in Fig. 1-2:
Submersible sewage pump 1 is the anaerobic oxidation pond with 13, No. 1 ponds, sewage transport to 1 pond 13, and No. 1 pond 13 has the function that septic tank is regulated water quality; It is the anaerobic oxidation pond that sewage enters 14, No. 2 ponds, No. 2 ponds 14 through 13 backs, No. 1 pond by baffling pipe 21 bafflings, and the effect of baffling pipe 21 is the paths that prolong sewage, increases the residence time of sewage; Sewage enters pond 15 through 14 backs, No. 2 ponds No. 3 by baffling pipe 21 bafflings, No. 3 pond 15 is the anaerobic oxidation pond, and three-phase sparger 23 has water, mud, the isolating function of gas in No. 3 ponds 15, and water enters pond 16 No. 4 through baffling pipe 21, sludge settling is at the bottom of the pond, and gas is discharged by venting hole 4; Sewage enters pond 16 through 15 backs, No. 3 ponds No. 4 by baffling pipe 21 bafflings, No. 4 pond 16 is the aerobic oxidation pond, the middle part in No. 4 ponds 16 is compartments that upper and lower two-layer woven wire 24 constitutes, throw urethane filler 26 in the compartment into, gas distribution pipe 25 under lower floor's woven wire connects with outside aerator 7 pipes, and aeration is carried out in No. 4 ponds 16; Sewage enters 17, No. 5 ponds, No. 5 ponds 17 through 16 backs, No. 4 ponds by baffling pipe 21 bafflings and is the aerobic oxidation pond, and structure, function in No. 5 ponds 17 are identical with No. 4 ponds 16; Sewage is back by tapping into into No. 6 ponds 18 with water spraying pipe 31 through No. 5 ponds 17, No. 6 pond 18 is a settling tank, further precipitate the suspended substance of sewage, the effluent quality of from No. 6 pond 18 water outlets 9, discharging: COD≤150mg/L, suspended substance≤80mg/L, BOD≤60mg/L satisfies " farmland irrigating water's quality standard " (GB5084-2005).
