Background technology
Existing rural domestic sewage treatment facility is mostly very simple and crude, general three compartment septic tanks that adopt are processed, but it mainly bears the physical sedimentation effect, and processing efficiency is very low, poor effect, in water outlet, the concentration of organism and ammonia nitrogen is still very high, after the discharge surface water body, causes the water function serious degradation, the smelly blackening of water body, even fishes and shrimps disappearance, caused serious pollution to the water environment in rural area, seriously restricted the improvement of rural environment and the development of rural economy.The dissimilar underground powerless anaerobic processing device grown up in recent years, although more remarkable to removing the organic pollutant effect, the COD discharge can reach " integrated wastewater discharge standard " one-level or the requirement of secondary limit value substantially.But " integrated wastewater discharge standard " (GB18918-2002) I and II standard code ammonia nitrogen allows emission limit to be respectively 5mg/L (one-level B is 8mg/L) and 25mg/L, because being limited to the design defect of this type of technique and technology, existing treatment technology and facility water outlet NH 3-N is difficult to up to standard, and in the urgent need to researching and developing high-efficient simple domestic sewage in rural areas by using denitride technology or existing apparatus being carried out to biological reinforced processing, this is that current technology for treating domestic sewage in rural area is badly in need of the significant problem solved.
The utility model content
The purpose of this utility model is to provide the one way of life waste disposal plant, realizes the efficient processing to sanitary sewage.
The utility model is that the technical scheme that its technical problem of solution adopts is,
Sewage treatment unit, comprise anoxic pond, aerobic reactor and settling tank, anoxic pond is communicated with source of sewage by pipeline, sewage promotes and enters in anoxic pond through pump, and the water outlet of anoxic pond is communicated with aerobic reactor, and the sewage after processing in anoxic pond enters aerobic reactor, be provided with flow-disturbing mechanism in aerobic reactor, the water outlet of aerobic reactor is communicated with settling tank, and the sewage after processing in aerobic reactor enters settling tank, after being processed by settling tank, discharges;
Particularly, be provided with water entry in aerobic reactor, this water entry extends to bottom from the aerobic reactor top, flow-disturbing mechanism arranges around this water entry, sewage flows out from its bottom from the water entry top enters, and flows through arrival aerobic reactor top after flow-disturbing mechanism, from the aerobic reactor overhead stream to settling tank, aerobic reactor bottom is provided with aeration mechanism, by aeration mechanism, is become better in oxygen reactor and is passed into air;
Flow-disturbing mechanism comprises one group of corrugated plate, and this corrugated plate surface is provided with the urethane filler, and each corrugated plate extends from the aerobic reactor top to its bottom;
Be provided with the reverse screw paddle stirrer in anoxic pond, the anoxic pond top has lid, in this lid, is provided with venting port, and the gas in anoxic pond is discharged from this venting port.
The utility model has the advantage of, be provided with the reverse screw paddle stirrer in the anoxic pond of this device, both can play stirring action, can hold back mud again, improve sludge concentration, sewage flows into aerobic reactor certainly after processing in anoxic pond, corrugated plate vertically is set in aerobic reactor, corrugated plate surface attachment Polyurethane filler, the corrugated plate design had both improved the clear height ratio greatly, increased flow path, play the effect of holding back mud, allow sewage that the filler contact reacts on sufficient time and corrugated plate is arranged, also increased the path of aeration bubble, improved oxygen-transfer efficiency, play energy-conservation effect, sewage flows into settling tank afterwards, the mud of settling tank and Digestive system mixture through pump reflux to anoxic pond, nitrate in water produces anti-nitration reaction in anoxic pond, nitrate is converted to nitrogen, thereby the nitrogen pollutant in removal water.
The accompanying drawing explanation
Fig. 1 is the structural representation of the sewage treatment unit that the utility model proposes.
Embodiment
For technique means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with illustrating and specific embodiment, further set forth the utility model.
As shown in Figure 1, the sewage treatment unit the utility model proposes comprises anoxic pond 1, aerobic reactor 2 and settling tank 3, anoxic pond 1 is communicated with source of sewage by pipeline, sewage promotes and enters in anoxic pond 1 through pump, the water outlet of anoxic pond 1 is communicated with aerobic reactor 2, sewage after processing in anoxic pond 1 enters aerobic reactor 2, be provided with flow-disturbing mechanism in aerobic reactor 2, the water outlet of aerobic reactor 2 is communicated with settling tank 3, sewage after processing in aerobic reactor 2 enters settling tank 3, after being processed by settling tank 3, discharges;
Be provided with water entry 4 in aerobic reactor 2, this water entry 4 extends to bottom from aerobic reactor 2 tops, flow-disturbing mechanism arranges around this water entry 4, sewage flows out from its bottom from water entry 4 tops enter, arrive aerobic reactor 2 tops after flowing through flow-disturbing mechanism, from aerobic reactor 2 overhead stream to settling tank 3, aerobic reactor 2 bottoms are provided with aeration mechanism, by aeration mechanism, are become better in oxygen reactor 2 and are passed into air;
Flow-disturbing mechanism comprises one group of corrugated plate 5, and these corrugated plate 5 surfaces are provided with the urethane filler, and each corrugated plate 5 extends from aerobic reactor 2 tops to its bottom;
Be provided with reverse screw paddle stirrer 6 in anoxic pond 1, anoxic pond 1 top has lid, in this lid, is provided with venting port, and the gas in anoxic pond 1 is discharged from this venting port.
