Active sand filter for filtering suspended matter is based on countercurrent action, and raw water to be processed passes through position through water inlet pipe
Enter filter in the water distributor of filter bottom, water flow is from bottom to top countercurrently by filter bed, and filtered fluid after filtering is in mistake
Aggregation, flows out through overflow port at the top of filter.System for filtering active sand is a kind of efficient mistake for integrating coagulation, clarification, filtering
Treatment process is filtered, is made of multiple active sand filter units for filtering suspended matter.It is not required to shut down backwash；Using list
Grade filtrate, is not necessarily to gradation, and no waterpower is unevenly distributed and the problems such as primary filtrate；It does not need backwash pump and its shuts down switching use
Electronic, operated pneumatic valve；Without setting up coagulation, clarifying basin, without coagulation, clarification mechanical equipment.Therefore, system for filtering active sand
Occupied area is more compact, and operating cost is more economical.Raw water enters filter interior by water inlet pipe, and evenly distributes through water distributor
Pass through filter material layer and outlet to adverse current on afterwards.In the process, raw water is filtered, and the pollutant load in water reduces；Stone simultaneously
The content of pollutant increases in sand filtrate, and the pollutant load of lower layer's filter material layer is higher than upper layer filtrate.Positioned at filter
In the sand-washing device that the quartz sand filter media of bottom is promoted to filter top under the action of air compressor machine by the air lift in center
Cleaning.Filter bed is returned to after sand grains cleaning, while will cleaning produced pollution beyond the region of objective existence row.In the filter due to quartz sand filter media
In top-down motion state, stirring action is played to raw water, therefore stir flocculation to complete in filter.Filter
Interior filtrate cleaning in time, can bear higher water inlet pollutant concentration.Active sand filter for filtering suspended matter is special
Internal structure and its own characteristic, so that coagulation, clarification, filtering are fully completed in the same pond body.System for filtering active sand
By the concrete pond of corresponding construction, tapered filter sand guiding device, self-filtering unit, water inlet line, filtrate effluent pipeline, punching
The composition such as elastic connection, air compressor machine and control system between wash water outlet pipe, self-filtering unit and corresponding pipeline.Self-filtering
Unit includes inlet and outlet pipes, water distributor, sand-washing device, flushing water outlet pipe and air lift casing etc..Inlet and outlet pipes
The top of filter element is all located at flushing water outlet pipe.The contaminated filtrate of filter bottom is elevated by air lift
To the sand-washing device of filter top, separate pollutant from active sand by action of turbulent flow, impurity is gone out by ejected wash water
Mouth discharge, net sand return to casting bed to realize continuous filtering using self weight.
