Description
Technical field
The utility model is related to a kind of drinking water treatment filter tank.More particularly to a kind of upward flow floating media filter.
Background technology
At present, the handling process of China's overwhelming majority earth surface water source waterworks is common process, i.e. coagulation, precipitation, mistake
Filter and sterilization.Wherein, filter element generally using it is lower to stream filter tank, filtrate based on quartz sand, part water factory using anthracite,
Heavy mineral and activated carbon (relative density of this several filtrate is both greater than 1).Conventional filter tank species mainly have conventional rapid filter,
V-type filter tank, valveless filtering pool, siphon filter, moving flushing cage filter chamber etc., use V-type more newly-built the big-and-middle-sized waterworks at present
Filter tank.
Above-mentioned filter tank is primarily present problems with：
1st, filtrate is relatively costly, and filter tank structure is complex.
2nd, the aperture resistance of large resistance underdrain system is big, and power consumption during backwash is big.Water system is matched somebody with somebody in even slight drag
System, because filtrate proportion is larger, power consumption during flushing is also larger.
3rd, because manufacturing process is limited, the particle diameter of filtrate is difficult to accomplish completely the same, China use effective grain size and
Nonuniformity coefficient method, the effective grain size d10=0.55, K80 of individual layer quartz sand filter media<2.0.When filter tank is recoiled using high-velocity flow
When washing, the current for flowing up can float filtering layer to hold up and, and sand grains is in suspended state, and it is existing to occur hydraulic classiciation automatically
As, i.e., the small sand grains of particle diameter be located at upper strata, the big sand grains of particle diameter be located at lower floor, it is lower to stream filter tank strainability thus can drop
It is low.Even using the even-granular filter of air-water backwashing, filtering layer can also be presented in various degree unavoidably after the operation long period
Hydraulic classiciation phenomenon.
4th, it is lower to filter is flowed through when, in filtering layer retain impurity can more and more, current flow through filtering layer the loss of flood peak understand by
It is cumulative big, when the loss of flood peak of a certain depth exceedes the depth of water at this below sand face, negative pressure appearance will occur.In negative pressure
Area, originally gas soluble in water can constantly discharge.Escaping gas brings two kinds of consequences：One is to reduce effective filtering surface
Product, increases filtering layer local resistance, increases the loss of flood peak；Two is that bubble can penetrate filtering layer, rises to filter tank surface, takes away lightweight
Or thin matter filtrate, structure of filtering layer is destroyed, in backwash, bubble is easier to take away a large amount of filtrates.
Utility model content
Problem to be solved in the utility model is to provide a kind of low cost, simple installation and the strong upward flow of dirt-removing power is light
Matter filter material filter pool, it is proposed that following technical scheme：
A kind of upward flow floating media filter, the filter tank is divided into three layers, and bottom, middle level and top are sequentially provided with from top to bottom
Layer, raw water canal and water distributing area that filter tank bottom is communicated with, the raw water canal is communicated with raw water tubes and backwash water pipe, described to match somebody with somebody
Pool bottom is provided with a gas washing pipe, and the gas washing pipe passes through filter tank side wall；Filter tank middle level is provided with the mistake being made up of light filter material
Filtering layer and drainage ditch, the filter layer and drainage ditch are separated with dividing plate, and the dividing plate middle part is set to side parietal suture gap filter plate, the side
Baffle plate of the slant setting in filter layer is provided with the top of parietal suture gap filter plate；Clear water zone and clear water canal that filter tank top layer is communicated with,
The clear water zone bottom is provided with top gap filter plate, and the clear water canal is communicated with clear water pipe and initial filter water discharge spout.
Further improvement of these options, the light filter material material is plastics.
Further improvement of these options, top gap filter plate and the side parietal suture gap filter plate are by plastics system
Into.
Further improvement of these options, the raw water tubes, backwash water pipe, gas washing pipe, drainpipe, clear water pipe and just
Drainage delivery pipe is fitted with a switch valve.
Further improvement of these options, the pipeline in water distributing area of the gas washing pipe is perforated pipe.
Further improvement of these options, the perforation pipe surface is provided with evenly distributed multiple steam vents.
The beneficial effects of the utility model are：
(1) material of light filter material is plastics (such as polyethylene), and manufacturing cost is relatively low, and particle diameter of filter medium is more uniform,
Entirely filtering layer is stronger containing dirty ability.Because the proportion of light filter material is much smaller than quartz sand, the intensity that water is rinsed need to only meet handle
Impurities in water is drained, and backwash rate is obviously reduced under the conditions of same washing time, i.e., washing water quantity can be reduced.In order to
Resistance is excessive caused by all filtrates are squeezed in upper layer gap filter plate lower section when avoiding backwash, is especially set on the pool wall of side
Gap filter plate discharge backwashing wastewater is put.Unique side parietal suture gap filter plate design so that when water is rinsed, the water level meeting in pond
Drop to the distance below of top gap filter plate, the Fluidization of light filter material is increased, power consumption when water is rinsed
Can reduce.
(2) filter type is upward flow, without worrying negative pressure appearance.
(3) design of top gap filter plate, it is to avoid the loss of light filter material.
(5) current can be directly entered upper strata filtrate and send out by side parietal suture gap filter plate by lower floor's filtrate when in order to avoid filtering
Raw short circuit, especially an inclined baffle plate is increased in the present apparatus.Unique baffle design so that current are along side parietal suture gap filter plate
The path extension of filtering, resistance increase, largely avoid the generation of short circuit problem, it is ensured that water after filter matter upwards.
(6) due in running stress it is smaller, top gap filter plate and side parietal suture gap filter plate can be made of plastics, into
This is relatively low, easy for installation.
(7) bed rearrangement filter tank structure is relatively simple, it is easy to accomplish automation.
