Description
Technical field
The utility model relates to field of sewage treatment equipment, especially efficient sedimentation tank and sewage disposal system.
Background technique
Sedimentation basin is a kind of structures or equipment that suspended matter in water removal is removed using precipitation, utilizes the naturally heavy of water
It forms sediment or the effect of coagulating sedimentation removes the suspended matter in water, sedimentation basin is divided into horizontal sedimentation basin and vertical precipitating by water (flow) direction
Pond, wherein the waste water of vertical sedimentation basin is discharged into pond from top to bottom by the water inlet pipe for being located at sedimentation basin center, and then waste water is along pond
Entire section slowly rise, suspended matter is settled under the effect of gravity in bottom of pond taper sludge bucket, primary water from pond upper end week
It is discharged in the overflow weir enclosed, can guarantee outlet effect by reasonably designing water intake velocity, sedimentation time etc., but it is still
With certain problem:
(1) uniformity of water inlet pipe water distribution is bad, and larger to the impact of settling zone, easily causes the disturbance of suspended matter, shadow
Ring sedimentation effect.
(2) in order to accelerate the precipitating of suspended matter, it is obliquely installed one group of parallel corrugated inclined plate in pond usually to shorten
Then the sedimentation stroke of particulate matter, still, the wave trough position that suspended matter needs to be moved to bellows are sunk in sludge bucket, still
Since trough only accounts for the general breadth of inclined plate, cause the aisle spare of suspended substance sedimentation to greatly reduce, causes to change water
Road influences precipitation surface load, this results in the reduction of sludge settling speed, problem of the suspended matter siltation on inclined plate easily occurs,
The use of sedimentation basin is seriously affected.
(3) multiple inclined plates are often and are installed in sedimentation basin after overall package again, once a certain or certain inclined plates are broken
Damage then needs whole be moved out to outside pond to be replaced, affects normal use, and complicated for operation, or even need integral replacing, at
This height is not easy to maintain；It is usually present biggish gap meanwhile when overall package, between inclined plate and pool wall, easily occurs short
Stream causes to run mud problem, influences effluent characteristics.
