Description
Technical field
The present invention relates to the medium filter of sewage disposal, particularly to the media filtration of a kind of steel industry sewage disposal
Device.
Background technology
The environmental protection policy of country, it is desirable to highly water intensive industry (such as steel industry) improves the utilization ratio of water resource as far as possible.
After the sewer of each operation stage is generally collected by domestic large-scale steel industry, focus on, water in rear formation up to standard
Carry out reuse.
Steel industry sewage has the features such as low COD, high suspended matter, high concentrtion.Domestic be generally adopted by coagulating sedimentation+
The processing mode of media filtration.Preferable to the Pollutant Treatment such as float, turbidity effect in sewage water.In typically can also reaching
Water circulation standard.
But along with being gradually improved of water resources management, industrial and mining establishment are produced new book and takes increasingly tightening up of management.Having must
Will be by " middle water " resource further.It is back to use such as the high-quality water spot such as recirculated cooling water, boiler feedwater.It is right to need
The water quality of middle water improves further.
Steel industry sewage has the features such as low COD, high suspended matter, high concentrtion.Water also has the oils and fats of trace, iron ion
The situation such as exceed standard.Centering water carries out high-quality reuse and is necessary to control these indexs.
Use quartz sand media filtration generally for pollutant such as the float in water, can effectively remove；Oils and fats pollutes
Thing can use Endocarpium Juglandis medium to adsorb, and can effectively remove；Iron ion can use manganese sand filtering material, carries out being catalyzed oxidation and goes
Remove.
Need at quartz sand filtration+Endocarpium Juglandis filtration+filtration with manganese sand series connection so needing to reach above-mentioned effect
Reason.Significantly increase the investment of equipment, add the difficulty of operational management.
Summary of the invention
It is an object of the invention to provide a kind of for steel industry sewage disposal and reuse requirement, design have developed one
The medium filter that novel medium filtrate is combined.Effectively can remove oil removal, oils and fats, ferrum with a kind of equipment
The medium filter of the steel industry sewage disposal of the multiple pollutants such as ion.
The solution of the present invention is such that
A kind of medium filter of steel industry sewage disposal, the mistake connected into including cylinder and the end socket that is connected with cylinder two ends
Filter container, the top of filter container inner chamber has and includes the upper water-distributing device into water water dispensing apparatus, and bottom has employing bottom many
The lower water-distributing device that orifice plate is constituted with bottom single head sideshake formula water cap, is provided with between upper and lower cloth water-bound and includes that middle part is many
Orifice plate and the middle water-distributing device of double end sideshake formula water cap；It is placed with between upper and lower cloth water-bound and includes manganese sand filtering material, quartz sand
Filtrate, the medium filtrate of Endocarpium Juglandis filtrate, according to three kinds of medium filtrates by the descending arrangement of density be: manganese sand filtering material, quartz
Sand filtering material, Endocarpium Juglandis filtrate, be respectively put into upper and lower water distribution knot by manganese sand filtering material, quartz sand filter media, Endocarpium Juglandis filtrate from bottom to top
Between structure.
More specifically technical scheme also includes: described Endocarpium Juglandis filtrate is arranged on the top of middle water-distributing device, with quartz
Sand and manganese sand filtering material are completely isolated by middle water-distributing device, and described quartz sand filter media and manganese sand filtering material are arranged on lower water-distributing device
Top, arrangement mode is: quartz sand filter media-manganese sand filtering material-lower water-distributing device.Quartz sand filter media directly contacts not with manganese sand filtering material
Having physical isolation, the difference in specific gravity using both separates.
The invention have the advantage that
1, will originally need three kinds of filter series connection to process the effect that can be only achieved, just can be realized by a kind of filter.Pole
Big saving investment, typically can save more than 50% at this operation stage.
2, equipment occupation of land has saved 60%, saves cost of land.
3, system operation energy consumption has saved 50%.
4, equipment product aqueous suspension clearance reaches more than 80%, has reached the removal effect of quartz filter.
5, equipment product water oils and fats clearance reaches more than 70%, has reached the removal effect of Endocarpium Juglandis filter.
6, equipment product water iron ion removing rate reaches more than 90%, has reached the removal effect of manganese sand filter.
