Description
Technical field
The utility model relates to a kind of electroplating sewerage settling tanks, more specifically, it relates to a kind of anti-disturbance of electroplating sewerage
Three-level settling tank.
Background technique
Metal ion in the sewage and waste liquid of electroplate factory's discharge, with the presence of in the form of simple cation, some with
Acid group form exists, and some still belongs to carcinogenic and aberration inducing extremely toxic substance.How toxic electroplating sewerage is, and harmfulness is larger, without
Handle electroplating sewerage up to standard be discharged into river, pond or in depth under, can not only endanger environment, and can polluted drinking water and work
Industry water.The Cr VI that contains in electroplating sewerage environmental pollution and can seriously endanger human health, it is therefore necessary in earnest plus
With processing.
Currently, the system for being commonly used for electroplating sewerage processing, what is be widely used has following different types of processing side
Method: chemical precipitation method, and it is divided into neutralization precipitation method and sulphide precipitation；Solvent extraction and separation method；Absorption method；At redox
Logos, and it is divided into chemical reduction method, ferrite process and electrolysis method；Ion-exchange；Membrane separation process technology；Biologic treating technique.
But no matter above-mentioned any processing method is used, be all essential by settling pond body and being precipitated to sewage
Link, existing sedimentation pond body are usually all then to stand sewage, and flocculation is added directly by sewage after reaction tank introducing
Agent is drawn after particle sedimentation, then by oettIed sewage, is then further processed, this method is due to needing sewage
Static a period of time, therefore treatment effeciency is not high；And sometimes for sewage treating efficiency is improved, while being precipitated, sink
Shallow lake pond also can introduce and be discharged sewage, but since sewage flows into sedimentation basin from above sedimentation basin, can be to the aquatic products in sedimentation basin
Raw impact makes the water in sedimentation basin generate biggish fluctuation, therefore some particles can not precipitate.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of anti-disturbance three-levels of electroplating sewerage
Settling tank.
To achieve the above objectives, the present invention adopts the following technical solutions: a kind of anti-disturbance three-level sedimentation of electroplating sewerage
Pond, including first order settling tank, second level settling tank and third level settling tank, the first order settling tank, second level settling tank
Successively reduced with the height of third level settling tank, in the first order settling tank in upper place be equipped with it is closely sealed with first order settling tank
The lower section of semi-permeable membrane, the semi-permeable membrane is equipped with sewage water inlet pipe, and the first order settling tank is opposite to each other in one end of sewage water inlet pipe
Equipped with the first water outlet flushed with Chi Ding, the first drainage tube is connected on first water outlet, first drainage tube prolongs
Under the liquid level for reaching second level settling tank, the bottom of the second level settling tank is equipped with cotton-shaped felt, and Chi Ding is opposite to each other in first
One end of drainage tube is equipped with the second water outlet, and height is equipped with the second drainage tube on second water outlet, and second drainage tube prolongs
Under the liquid level for reaching third level settling tank.
Preferably, being equipped with water fender below second water outlet, the area of the water fender accounts for second level sedimentation
The 2/3 of the pond gross area.
Preferably, first drainage tube extends to below water fender.
The utility model compare compared with the prior art have the advantage that by using semi-permeable membrane by first order settling tank every
Disconnected to the full extent to stay in the pollutant to settle down below semi-permeable membrane, entire subsiding and purifying efficiency is very high, and structure
It is very simple, meanwhile, turbulent water leads to sedimentation when semi-permeable membrane can intake to avoid sewage water inlet pipe and the first outlet pipe is discharged
Pollutant is evoked by water flow, influences effect of settling, and the bottom in the settling tank of the second level is laid with cotton-shaped felt, can grab absorption
The pollutant of sedimentation improves subsiding and purifying effect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the anti-disturbance three-level settling tank embodiment of the utility model electroplating sewerage.
In figure: 1, first order settling tank；2, second level settling tank；3, third level settling tank；4, sewage water inlet pipe；5, semi-transparent
Film；6, the first water outlet；7, the first drainage tube；8, the second water outlet；9, the second drainage tube；10, cotton-shaped felt；11, water fender.
Specific embodiment
Disturbance three-level settling tank embodiment anti-to the utility model electroplating sewerage is described further with reference to the accompanying drawing.
A kind of anti-disturbance three-level settling tank of electroplating sewerage, including first order settling tank 1, second level settling tank 2 and the third level
The height of settling tank 3, first order settling tank 1, second level settling tank 2 and third level settling tank 3 successively reduces, first order settling tank
Upper place is equipped with the semi-permeable membrane 5 closely sealed with first order settling tank 1 in 1, and the lower section of semi-permeable membrane 5 is equipped with sewage water inlet pipe 4, the first order
Settling tank 1 is equipped with the first water outlet 6 flushed with Chi Ding in one end of sewage water inlet pipe 4 opposite to each other, is connected on the first water outlet 6
