Layer, sets watertight insulation 17 to prevent effluent seepage corrosion building raft foundation, and the outside of watertight insulation 17 of base plate 6 is spread
If pea gravel concreten layer 18, for protecting waterproof layer without damage, the outside masonry panel of watertight insulation 17 of basic secondary beam 8
19, the inwall of each lattice of septic tank is equipped with anticorrosive tile layer 20, avoids corrosion in water waterproof layer from causing seepage；
（4）The hole to be provided 22 set between each lattice of septic tank by the top of wall 19 connects, and ensures biogas through septic tank
The blast pipe 28 of interior setting drains into outdoor, assembles indoors to prevent biogas, ensures the safe operation of septic tank；The end of blast pipe 28
Fire resisting damper 29 is installed, has isolated the disaster hidden-trouble that outdoor naked light is brought；
（5）The casting concrete cover plate 23 on each lattice of septic tank, septic tank are respectively provided with inspection well cover per lattice crown center
24, facilitate maintenance of equipment and periodic cleaning septic tank；
（6）Sewage is sorted into septic tank, toilet sewage, rainwater, keep a public place clean waste water and other be free of grease and nuisance
The waste water of matter is directly discharged into septic tank water inlet 25, kitchen etc. to be needed first to be discharged into septic tank after oil interceptor is handled containing greasy sewage
Water inlet 25, hot waste water discharge should carry out cooling processing in advance, and medical treatment waits the waste water containing harmful substance to pass through at specialty
Discharged after reason, acidic and alkaline waste water discharges after needing neutralisation treatment, and the waste water of keeping a public place clean more than sediment charge discharges after preferably precipitating in advance；Sewage from
Septic tank water inlet 25 in the first lattice of septic tank 1 enters, retained in the first lattice of septic tank 1 excrement slag, initial fermentation, sterilization and
Worm's ovum is precipitated, is divided into three layers of upper, middle and lower naturally by preliminary sedimentation, fermentation, decomposition, the upper strata of floating and the lower floor of precipitation are stayed
Get off and continue to ferment, decompose, the intermediate layer tentatively clarified is continued fermentation into the second lattice of septic tank 2 and decomposed, and enters back into septic tank
3rd lattice 3 storage precipitation, is sequentially entered in each lattice of septic tank, finally substantially innoxious sewage enters by drainpipe 14
Stored in last lattice of septic tank, be thusly-formed multi-stage sewage processing system so that sewage disposal is more thorough.Septic tank is last
Is provided with drainage pipeline 27 in one lattice, drainage pipeline 27 connects dredge pump 26, when liquid level opens pump water more than septic tank last lattice
Dredge pump 26 starts behind position 30, and the sewage after processing is discharged into city planting ductwork through drainage pipeline 27, when liquid level is less than termination of pumping water level 31
Dredge pump 26 is stopped afterwards.
Septic tank is four lattice, on the basic secondary beam 8 between the first lattice of septic tank 1 and the second lattice of septic tank 2, septic tank
On basic secondary beam 8 between two lattice 2 and the lattice 3 of septic tank the 3rd and the base between the lattice 3 of septic tank the 3rd and the lattice 4 of septic tank the 4th
Bored on plinth secondary beam 8 and open multiple osculums 13, penetrate osculum 13 with drainpipe 14 so that the first lattice of septic tank 1 and septic tank
Between second lattice 2, between the second lattice of septic tank 2 and the lattice 3 of septic tank the 3rd, between the lattice 3 of septic tank the 3rd and the lattice 4 of septic tank the 4th
Interconnect.
Base plate 6, foundation girder 7 and the surface of basic secondary beam 8 in each lattice of septic tank polish flat, and rejected region is pre-
Respective handling measure is first taken, using closed material mending concrete surface crack, inner corner trim 11 is painted into fillet with cement mortar,
External corner 12 is polished into fillet so that coil waterproof layer 16 is gently excessive in negative and positive angular position, prevents bending is impaired from causing seepage.
To ensure to use safely, reconstruction of existing building engineering must is fulfilled for the requirement of existing state compulsory standard, transforms
Work progress should have reliable safety measure, and existing building raft foundation must not have an impact the crack of structure safety and seriously lack
Fall into, parking motor vehicles are forbidden on the ground in the range of sewage disposal system, and set that No Open Flames danger warning sign, sewage
