Description
Technical field
The present invention relates to more medium filter technical field, specially a kind of circulation type backwashes more medium filter.
Background technique
More medium filter is that the higher water of turbidity is passed through under pressure using one or more of filter mediums
Certain thickness granular or non-grain material, so that effectively removing suspended impurity makes the process of clarification of water, common filtrate has stone
Sand, anthracite, manganese sand etc. are mainly used for water process turbidity removal, softened water, prime pretreatment of pure water etc., more medium filter
(also known as mechanical filter) is using the anthracite of layered, sand, garnet fine crushing or other materials as bed, and one typical
The top layer of more medium filter, bed is made of most light and most crude product grade material, and the material of most heavy and most thin grade is placed on bed
Lower curtate.Its principle is by depth-type filtration -- and biggish particle is removed in top layer in water, and lesser particle is in filter media
Higher depth be removed.Thus the standard after making water quality reach coarse filtration.Equipment is pressure type, and principle is when raw water is from upper
When passing through filtrate under and, suspended matter is retained down since absorption is acted on mechanical choked flow by filtering layer surface in water, when water flows into filter
It is closer due to the sand grains arrangement in filter material layer when layer is intermediate, make particle in water there are more chances and sand grains to collide, then
Flocculation material, suspended matter and sand grain surface adhere to each other in water, and impurities in water is trapped in filter material layer, to obtain clear water
Matter.The backwash of filter is primarily referred to as filter after using some cycles, and filter material layer retains and adsorb a certain amount of sundries
And spot, this declines the effluent quality of filter, and flow reversal makes filtering layer expansion, suspends, by water flow by filter material layer
Shearing force and particle collision friction power cleaning filter material layer make the dirt in filtering layer be detached from and be discharged with backwash water, common is more
For medium filter when carrying out backwash operation, water-saving result is not satisfactory, generallys use the mode inversely intake to filter layer
Repeated flushing is carried out, the water after flushing is directly discharged, wastes water resource, increase the production cost of factory, and factory is given
Production brings great inconvenience.
