Principle and single homogeneous filtering material, filtering are carried out at the same time with washed-out sand.
Background technology：
In conventional secondary biochemical treatment, active sand will be set coagulating basin and sedimentation basin in traditional three-stage treatment process indirectly
After secondary settling tank, advanced treating is carried out to secondary clarifier effluent, needs the process facilities such as ad hoc coagulating basin, clarifying basin.It cannot be direct
In back with water inlet line or channel dosing coagulant, active sand process engineering amount and investment business are higher, and operation and maintenance cost is high.
Invention content：
Up-flow thermopnore continuous filter unit and filter method are used the object of the present invention is to provide a kind of.
Above-mentioned purpose is realized by following technical scheme：
A kind of to use up-flow thermopnore continuous filter unit, composition includes：Housing, the housing respectively with raw water into
Mouth, the connection of washed-out sand outlet of sewer, water purification outlet, the enclosure interior have dirty sand, casting bed, the sand hopper that falls, the sand hopper
It is welded for sector structure part with tapering structural member.
Described uses up-flow thermopnore continuous filter unit, and the sand hopper that falls is connect with water distributor, the cloth
Hydrophone is connect with the original water inlet, and the washed-out sand outlet of sewer is connect by pipeline with collecting container, and described catchments
Container is connect with sand-washing device.
Described uses up-flow thermopnore continuous filter unit, and the sand hopper lower part of leading is equipped with air lift,
The husky device surface of washing is machined with round hole, and the water distributor is mounted on the upper of the sand hopper for trapezium structure part
Portion.
The filter method using up-flow thermopnore continuous filter unit, this method comprises the following steps：
Active sand filter is based on countercurrent action, and pending raw water enters filter interior by water inlet pipe, through bottom water distribution
Device evenly distributes backward superinverse circulation filter bed, the overflow discharge filter system after filter top is collected of the filtrate after filtering
System.Under the action of air compressor machine, the contaminated dirty sand of filter bottom is promoted to the washed-out sand of filter top by air lift
In device, the separated from contaminants on sand surface is gone out by the action of turbulent flow of flow.Net sand after cleaning returns to casting bed using dead weight
In, and sewage caused by cleaning sand is discharged from the sewage draining exit of filter.
Beneficial effects of the present invention：
1. the present invention is widely used in drinking water, industrial water, advanced treatment of wastewater and Treated sewage reusing process field.Active sand mistake
Filter（Also known as continuous shifting sand filter）Using up-flow thermopnore work principle of filter and single homogeneous filtering material, filtering and washed-out sand are simultaneously
Carry out, can 24 hours continuous automatic runnings, backwashed without shutting down, cleverly put forward sand and washed-out sand structure instead of the big work(of tradition
Rate backwashing system, energy consumption is extremely low, Maintenance free, and management is easy, can be unattended.
2. Collecting flocculation of the present invention, precipitation, filtration treatment simplify the flow of traditional handicraft processing, floor space in one
It is small；One-time investment is low, without setting up the facilities such as coagulating basin, clarifying basin, is set without backwashing pump and electronic, operated pneumatic valve etc.
It is standby；It is efficient, it is continuous to filter, it is backwashed without shutting down, no primary filtrate problem；Depth-type filtration, filter bed depth are 2000-
2500mm, good filtration effect, stable effluent quality；Filter bed head loss is small, about 0.5m；Continuous wash filtrate, can be in time
The impurity of filtering layer retention is removed, the water inlet of SS concentration≤150mg/L can be born, anti-influent quality impact load ability is strong；Engineering
Measure small, operating cost and maintenance cost are low；Modular construction is easy to reorganization and expansion.
3. active sand filter of the present invention is suitable for the processing such as industrial water, the advanced treating of sewage and Treated sewage reusing neck
Domain may be provided at conventional activated sludge method, extended aeration process, SBR system, oxidation ditch system, trickling filter system, oxidation pond system
Rear end.
4. active sand filter of the present invention is in direct contact filtering available for the surface water and groundwater of tap water, so as to take
Coagulating basin and the sedimentation basin pond to disappear in traditional three-stage treatment process；In conventional secondary biochemical treatment, active sand filter can
After being directly arranged in secondary settling tank, advanced treating is carried out to secondary clarifier effluent, without process facilities such as ad hoc coagulating basin, clarifying basins.It can
Directly in back with water inlet line or channel dosing coagulant, shuttling movement of the filtrate in filter can play stirring action.With routine
Three-stage filtering compares, and active sand filter technique makes quantities and investment significantly reduce, and operation and maintenance cost is low, avoids
Traditional three-stage treatment process facility is various, complex process, high investment and operating cost the shortcomings of.
