Abstract
The utility model relates to a sewage treatment device for integral oil removal and sedimentation aiming at accelerating separation between oil and water to float and ensuring good oil removing effect. The sewage treatment device for integral oil removal and sedimentation comprises a water inlet, an entrance channel, a sludge drainage channel, a water distribution lattice wall, an aerating device, a horizontal sedimentation tank, an effluent weir, a water outlet pipe and an oil collecting pipe. The water inlet is communicated with the entrance channel which is communicated with the horizontal sedimentation tank through the water distribution lattice wall; the sludge drainage channel is located in the center of the horizontal sedimentation tank and is arranged along the length direction of the horizontal sedimentation tank; the aerating device comprises an air intake pipe, a micropore aerator and a connection fixing piece; the micropore aerator is mounted at the bottom of the horizontal sedimentation tank close to the water distribution lattice wall and is arranged along the width direction of the horizontal sedimentation tank; the oil collecting pipe is mounted on the sewage plane of the horizontal sedimentation tank close to the tail end; the outlet of the oil collecting pipe is bent downward to the sludge drainage channel; water outlet grooves are mounted at the tail end of the horizontal sedimentation tank; the effluent weir is mounted between the water outlet grooves and the oil collecting pipe; and water from all the water outlet grooves is converged in the water outlet pipe.
Description
Technical field
The utility model relates to a kind of water treatment device.
Background technology
In the middle of sewage disposal, rectangular sedimentation tank can sink suspended solid and floating matter with removing in the sewage.After the waste water process advection sedimentation, but can remove 50% of hypostasis, grease and floating matter approximately.But some trade effluent oleaginousness is big, surpasses more than the 20mg/l, remove 50% petroleum-type of nature come-up through rectangular sedimentation tank, still can not alleviate the load of subsequent treatment process, influence the effect of subsequent treatment process, cause the final outflow water can not be up to standard.
Summary of the invention
The utility model purpose is for overcoming the deficiency of above-mentioned prior art, a kind of faster oil trap deposition all-in-one waste disposal plant that floats, deoils effective with water sepn of greasy dirt that promotes being provided.
The utility model comprises water-in, inlet channel, water distribution tracery wall, aerating apparatus, horizontal sedimentation tank, oil header, spoil disposal ditch, effluent weir, effluent trough and rising pipe; Water-in is communicated with inlet channel, and inlet channel is communicated with horizontal sedimentation tank by the water distribution tracery wall; Aerating apparatus comprises inlet pipe, micro-hole aerator and is connected and fixed part; Micro-hole aerator is installed in the horizontal sedimentation tank bottom, near water distribution tracery wall place, arranges along the horizontal sedimentation tank width.In order not influence sedimentation effect, the installation region width of micro-hole aerator is no more than 1/13 of horizontal flow basin total length.The spoil disposal ditch is positioned at horizontal sedimentation tank central authorities, arranges along the horizontal sedimentation tank length direction; Oil header is installed in horizontal flow basin near on the terminal sewage plane, and the curved downwards spoil disposal ditch that feeds of oil header outlet by handwheel rotation oil header angle, casts aside the greasy dirt on the face of pond, flows into pond intermediary spoil disposal ditch by the oil header outlet, together drains with mud.Effluent weir and effluent trough all are that steel plate is made, and effluent trough is installed in the horizontal flow basin end, and effluent weir is installed between effluent trough and the oil header, and effluent trough is connected with rising pipe; Sewage flows into effluent trough through deoiling post precipitation by effluent weir, comes together in and flows to down operation in the rising pipe.Aerator is selected two-way Endura ∮ 50 aerating tube-type micropore devices for use, and aeration is even, impacts for a short time, is easy to oil and the separating of water, and does not influence sedimentation effect.
Pressurized air produces a large amount of micro bubbles by aerator in water, make it attached on the suspension greasy dirt particle, causes the state of density less than water, utilizes law of buoyancy that it is kept afloat, thereby reaches the purpose of deoiling.Suspended solid when sewage enters the settling region through flowing into the district in the water is precipitated to the pond under action of gravity at the bottom of, supernatant liquor enters next procedure through the effluent trough of pond end, and mud is extracted into the spoil disposal ditch by suction dredger and drains.
The utility model can the many usefulness in a pond, not only may be used solely to remove to sink suspended solid and floating matter, also can be used as the facility that deoils specially, or collection precipitation, oil removing both be one.The specified service area according to waste water oil-contg, inflow district's area and selected aerator of aerator quantity is determined.Realized utilizing a kind of water processing establishment to reach the effect of settling tank and air flotation pool.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, water-in, 2, inlet channel, 3, inlet pipe, 4, the water distribution tracery wall, 5, micro-hole aerator, 6, the spoil disposal ditch, 7, oil header, 8, effluent weir, 9, effluent trough, 10, rising pipe, 11, horizontal sedimentation tank, 12, flow into the district.
Embodiment
The material of micro-hole aerator 5 can be selected polypropylene, EPDM rubber diaphragm, stainless steel PVC for use, or the molectron of several materials.Micro-hole aerator 5 is installed in 12 bottoms, inflow district of horizontal sedimentation tank 11, and in order not influence sedimentation effect, micro-hole aerator 5 is installed width can not surpass 1/13 of horizontal sedimentation tank 11 total lengths.Micro-hole aerator 5 used sources of the gas are pressurized air pipe network air, and the trend of compressed air pipe arranges according to the scene is actual, insert micro-hole aerator at the bottom of the pond, and aeration is even, impact for a short time, are easy to separating of oily and water.
