Principle and single homogeneous filtering material, filtering are carried out simultaneously with washed-out sand.
Background technology：
In conventional secondary biochemical treatment, active sand will set coagulating basin and sedimentation basin in traditional three-stage treatment process indirectly
After second pond, advanced treating is carried out to secondary clarifier effluent, it is necessary to the process facility such as ad hoc coagulating basin, depositing reservoir.Can not 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.
The content of the invention：
It is an object of the invention to provide a kind of continuous raw streaming active sand filtration treatment device and filter method.
Above-mentioned purpose is realized by following technical scheme：
A kind of continuous raw streaming active sand filtration treatment device, its composition includes：Housing, described housing enters with raw water respectively
Mouth, the connection of washed-out sand outlet of sewer, pure water inlet, described enclosure interior have dirty sand, casting bed, the sand hopper that falls, described sand hopper
For sector structure part and tapering structural member are welded.
Described continuous raw streaming active sand filtration treatment device, the described sand hopper that falls is connected with water-locator, described cloth
Hydrophone is connected with described original water inlet, and described washed-out sand outlet of sewer is connected by pipeline with collecting container, and described catchments
Container is connected with sand-washing device.
Described continuous raw streaming active sand filtration treatment device, described sand hopper bottom of leading is provided with air lift,
Described husky device Surface Machining of washing has circular port, and described water-locator is trapezium structure part installed in the upper of described sand hopper
Portion.
The filter method of described continuous raw streaming active sand filtration treatment device, the 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.In the presence of air compressor machine, the contaminated dirty sand of filter bottom is promoted to air lift the washed-out sand of filter top
In device, the separated from contaminants on sand surface is gone out by the action of turbulent flow of current.Net sand after cleaning returns to casting bed using deadweight
In, and the sewage produced 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 is with washed-out sand simultaneously
Carry out, can 24 hours continuous automatic runnings, backwashed without shutting down, cleverly carry sand and washed-out sand structure instead of traditional big work(
Rate backwashing system, energy consumption is extremely low, Maintenance free, and management is easy, can be unattended.
Collecting flocculation of the present invention, precipitation, filtration treatment simplify the flow of traditional handicraft treatment in one, and floor space is small；
One-time investment is low, without setting up the facilities such as coagulating basin, depositing reservoir, without the equipment such as backwashing pump and electronic, operated pneumatic valve；Effect
Rate is high, continuous filtering, is backwashed without shutting down, without first filtrate problem；Depth-type filtration, filter bed depth is 2000-2500mm, filtering
Effect is good, stable effluent quality；The filter bed loss of flood peak is small, about 0.5m；Continuous wash filtrate, can in time remove filtering layer retention
Impurity, the water inlet of SS concentration≤150mg/L can be born, anti-influent quality impact load ability is strong；Quantities is small, operating cost
It is low with maintenance cost；Modular construction, it is easy to reorganization and expansion.
Active sand filter of the present invention is applied to the process fields such as industrial water, the advanced treating of sewage and Treated sewage reusing,
May be provided at conventional activated sludge method, extended aeration process, SBR system, oxidation ditch system, trickling filter system, oxidation pond system
Rear end.
Active sand filter of the present invention can be used for the directly contact filtering of the surface water and groundwater of running water, so as to cancel
Coagulating basin and sedimentation basin pond in traditional three-stage treatment process；In conventional secondary biochemical treatment, active sand filter can be straight
After being connected in second pond, advanced treating is carried out to secondary clarifier effluent, without process facilities such as ad hoc coagulating basin, depositing reservoirs.Can be straight
Back with water inlet line or channel dosing coagulant are connected on, shuttling movement of the filtrate in filter can play stirring action.With conventional three
Segmentation filtering compares, and active sand filter technique makes quantities and investment significantly reduce, and operation and maintenance cost is low, it is to avoid
Traditional three-stage treatment process facility is various, complex process, investment and the shortcomings of operating cost high.
