Description
Technical field
Pipe network systems design area is collected the invention belongs to dispersant type domestic wastewater, is applied in particular to one kind
The inspection shaft of Domestic sewage collecting.
Background technology
Problem of environmental pollution has been increasingly becoming the livelihood issues of social common concern, and causes government and State Council's neck
The great attention led.Wherein, the unified of sanitary sewage collects the Environmental security health that treatment directly concerns the people, strengthens life
Sewage pollution preventing and treating living, curbs environmental pollution, and can fundamentally change traditional life sewage and disperse what is discharged and digest naturally
Present situation, and then advance process and the development of pro-environmental society work.
The construction of biological sewage pipe network system is then the most key and basic part in sewage disposal system, country and government
Also substantial amounts of material resources manpower has been put into this respect to be studied and built.Wherein, family inspection shaft is connect in present pipe network system
Use simple plastic well, brick well or fabricated cement concrete inspection shaft more.The structure of these inspection shafts is more simple
It is single, there are problems, it is mainly reflected in the following aspects：
1st, structure is single, it is impossible to realize the isolation and treatment to materials such as impurity in sanitary sewage and greases；
2nd, barrier performance is not enough, sealing is poor, the easy seepage of sanitary sewage, and serious pollution is caused to underground water；
3rd, the object such as impurity and scum silica frost is unprocessed is directly entered sewage network, finally easily causes the blocking of pipe network and breaks
It is bad, bring huge economic losses and environmental hazard.
The content of the invention
For above-mentioned problems of the prior art, it is contemplated that being given birth to for waste pipe network system provides a kind of being applied to
The inspection shaft of sewage collecting living, effectively can carry out preliminary treatment to sanitary sewage, be sewage collection and sewage network it is smooth
Logical operation provides strong technology and material guarantee.
To realize above-mentioned technical purpose, above-mentioned technique effect is reached, the present invention is achieved through the following technical solutions：
A kind of inspection shaft suitable for Domestic sewage collecting, is made up of, the well prefabricated well seat, pit shaft and movable manhole cover
Cylinder is arranged on well seat, and the movable manhole cover is arranged on the top of the pit shaft, and the inside of the pit shaft is longitudinally disposed
There are two pieces of active clapboards, two pieces of active clapboards are laterally inside separated into oil interceptor, filtering ponds and heavy by the pit shaft
Shallow lake pond；The top of the pit shaft is provided with the water inlet pipe and oil collecting pipe connected with the oil interceptor, and the position of the oil collecting pipe is high
Degree is slightly below the position height of the water inlet pipe, and the bottom of the pit shaft is provided with the outlet pipe connected with the sedimentation basin；Institute
The middle and lower part for stating filtering ponds is horizontally arranged with a dismountable permeable stainless steel string bag, the two ends of the permeable stainless steel string bag
It is separately fixed at two pieces of active clapboards；A filtering ponds are offered on the active clapboard of the oil interceptor side
Water inlet, the position height of the position height higher than the permeable stainless steel string bag of the filtering ponds water inlet；Positioned at described heavy
A filtering ponds delivery port is offered on the active clapboard of shallow lake pond side, the position height of the filtering ponds delivery port is less than
The position height of the permeable stainless steel string bag.
Further, the material of the well seat and the pit shaft is high-density polyethylene plastics.
Further, the cross section of the pit shaft is circle, is easily installed and saves floor occupying area, the more square inspection of crushing resistance
Look into well more preferable；Circular pit shaft outside is unified overall, can be split with well seat and the process such as zoarium.
Further, the material of the movable manhole cover can as needed select plastics or cement concrete constructions, facilitate right
Inspection shaft is overhauled.
Further, the active clapboard uses draw-in groove Seal Design, it is ensured that only between various pieces in the pit shaft
Vertical property and water proofing property, it is to avoid the current between each several part interact.
Further, the two ends of the permeable stainless steel string bag respectively by movable bolt be fixed on two pieces it is described activity every
Plate, the impurity screening that the permeable stainless steel string bag is collected into can periodically carry out dismounting cleaning, easy to operate simple, be easy to dimension
Shield.
Further, the active clapboard, the permeable stainless steel string bag and the movable bolt make antiseptic and rustproof place
Reason, it is to avoid sewage causes damage to the structure of inspection shaft, the strong of inspection shaft is ensure that while inspection shaft service life is extended
Degree and stability.
Further, the bottom of pond of the sedimentation basin is provided with dismountable precipitation inclined plate, the position of described precipitation inclined plate one end
Put height it is equal with the position height of the filtering ponds delivery port lower edge, the position height of the precipitation inclined plate other end with it is described
The bottom of pond of sedimentation basin is approached.
Operation principle of the invention is as follows：
Food waste sewage, gray water and other sanitary sewages for being collected into by water-service pipe net flow to the water inlet of inspection shaft；
Sewage flows into oil interceptor from the water inlet of inspection shaft first, and oil interceptor employs flat flow construction, and sewage is in oil interceptor along water
Square to slow flowing, because the suspensions such as Oil in Sewage Water fat are different with the proportion of water, therefore in flowing, the oil product in sewage
Float up to surface, oil layer flows out from oil collecting pipe, be collected into drain sump and focused on.
And the sewage after oil removing then enters filtering ponds by the filtering ponds water inlet on active clapboard；Into the dirt of filtering ponds
Water from top to bottom by the filtering of the permeable stainless steel string bag, by some impurity in sanitary sewage and the larger solid of volume
Grain is intercepted；The space of the permeable stainless steel string bag can be determined according to water quality index such as specific sanitary sewage SS, it is ensured that can
Large granular impurity and rubbish etc. in filter sewage.
It is heavy that sewage after being filtered through the permeable stainless steel string bag is flowed into by the filtering ponds delivery port on another piece of active clapboard
Shallow lake pond, coprecipitation mode is advection sedimentation；The precipitation inclined plate of sedimentation basin bottom can ensure the horizontal flow velocity of sewage in 5mm/s~7mm/
Between s；Sewage network can be then flowed directly into by the sewage after sedimentation basin treatment make unified collection treatment.
When after inspection shaft is using a period of time, it is necessary to when it is cleared up and is safeguarded, can first by permeable stainless (steel) wire
Pocket is taken out, and impurity thereon is cleared up, and the precipitation inclined plate taking-up of active clapboard and sedimentation basin is cleared up and safeguarded.
Inspection shaft dismounting of the invention and easy to assembly, maintenance work convenient and efficient, periodic cleaning can extend inspection shaft service life, protect
Card sanitary sewage flows unimpeded and treatment effect.
Compared with prior art, the beneficial effects of the invention are as follows：
