Abstract
The utility model discloses one kind to become hole filtering pool, including pond body 1, it is characterised in that：Filter layer 2 is provided with described pond body 1, the filtrate that the filter layer 2 uses is formed for rubble sand and fine quartz sand, and the ratio between particle diameter of rubble sand and fine quartz sand is not less than 140 not less than 6, weight ratio.Change hole filtering pool of the present utility model mainly uses coarse media, it is filtered by whole filter layer, this avoid the surface filtration that general filter chamber forms filter layer, reduces filtering layer resistance, penetrating too early for suspended particle is it also avoid, filtering velocity can also be improved；The addition of fine filtering material simultaneously mixes the local porosity for significantly reducing coarse media in filter layer, improves the flocculation of fine particle in sewage, is more beneficial for the removal to fine particle, also drastically increases the retaining power in filter tank；With the characteristics of equipment investment is low, occupation of land is small, good filtration effect, short filtration time, suitably promote the use of.
Description
Technical field
Water-treatment technology field is the utility model is related to, specifically a kind of equipment investment is low, takes up an area small, filter effect
Change hole filtering pool good, filtration time is short.
Background technology
Existing filter tank only forms the surface filtration of filtering layer, and filtering layer resistance is larger, causes wearing too early for suspended particle
Thoroughly, filtering velocity is slower；The local porosity of filtrate is larger, the flocculation unobvious of fine particle in sewage.
The content of the invention
The purpose of this utility model is the problem of presence for prior art, there is provided a kind of equipment investment is low, takes up an area small, mistake
The filter change hole filtering pool that effect is good, filtration time is short.
The purpose of this utility model solves by the following technical programs：
One kind becomes hole filtering pool, including pond body, it is characterised in that：Filter layer, the filter layer are provided with described pond body
The filtrate used is formed for rubble sand and fine quartz sand, and the ratio between particle diameter of rubble sand and fine quartz sand is not less than 6, weight
The ratio between be not less than 140.
The particle diameter of the rubble sand is 3.5mm~4.0mm.
Described filter layer is supported using the supporting plate for being evenly arranged water collection cap, and the lower section of supporting plate is gathering ground
And the pond body at gathering ground is provided with delivery port.
The particle diameter for entering water space and being less than fine quartz sand of the water collection cap.
Pond body at the gathering ground is provided with backwashing water import and the bottom of gathering ground is provided with drain.
The utility model has the following advantages compared with prior art：
Change hole filtering pool of the present utility model mainly uses coarse media, and it is filtered by whole filter layer, this
Sample avoids the surface filtration that general filter chamber forms filter layer, reduces filtering layer resistance, it also avoid the mistake of suspended particle
Early penetrate, filtering velocity can also be improved；The addition of fine filtering material simultaneously mixes the partial bores for significantly reducing coarse media in filter layer
Gap rate, the flocculation of fine particle in sewage is improved, be more beneficial for the removal to fine particle, also drastically increase filter
The retaining power in pond；With the characteristics of equipment investment is low, occupation of land is small, good filtration effect, short filtration time, suitably promote the use of.
Brief description of the drawings
Accompanying drawing 1 is the structural representation of the present utility model for becoming hole filtering pool.
Wherein：1-pond body；2-filter layer；3-water collection cap；4-supporting plate；5-gathering ground；6-delivery port.
Embodiment
The utility model is further described with embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1：One kind becomes hole filtering pool, including pond body 1, filter layer 2 is provided with pond body 1, filter layer 2 is using equal
The even supporting plate 4 for being disposed with water collection cap 3 is supported, and the lower section of supporting plate 4 is to be set in the pond body 1 at gathering ground 5 and gathering ground 5
There is delivery port 6；The filtrate that filter layer 2 uses is formed for rubble sand and fine quartz sand, the particle diameter of rubble sand for 3.5mm~
The ratio between 4.0mm and the particle diameter of rubble sand and fine quartz sand are not less than 140 not less than 6, weight ratio.In said structure, collection
The particle diameter for entering water space and being less than fine quartz sand of water cap 3；The pond body 1 at gathering ground 5 is provided with backwashing water import and collection simultaneously
The bottom in pool 5 is provided with drain.
It is a kind of positive stream deep-bed filter with " orthokinetic coagulation " Theoretical Design to become hole filtering pool, and it than is generally made using one kind
The bigger filtrate of particle diameter of filter medium and another particulate filtrate mix filter bed by a certain percentage, become what hole filtering pool used
Particle diameter of filter medium and shared ratio difference are larger.Become hole filtering pool and mainly use coarse media, be integral filter, so filtering layer
Resistance is small, and filtering velocity is higher, is not easily blocked, the situation of surface filtration when will not form thin media filtration, and contamination capacity is high, backwash
Cycle is grown, and adds limited amount fine filtering material, and is dispersed in whole filtering layer, significantly reduces the partial bores of coarse media
Gap rate, realize the effect to tiny suspended particulate " orthokinetic coagulation " in water.
Change hole filtering pool of the present utility model mainly uses coarse media, and it is filtered by whole filter layer 2, this
Sample avoids the surface filtration that general filter chamber forms filter layer 2, reduces the resistance of filter layer 2, it also avoid suspended particle
Penetrate too early, filtering velocity can also be improved；The addition of fine filtering material simultaneously mixes the part for significantly reducing coarse media in filter layer 2
Porosity, the flocculation of fine particle in sewage is improved, be more beneficial for the removal to fine particle, also drastically increase
The retaining power in filter tank；With the characteristics of equipment investment is low, occupation of land is small, good filtration effect, short filtration time, suitable promote makes
With.
Above example is only to illustrate technological thought of the present utility model, it is impossible to limits protection model of the present utility model with this
Enclose, it is every according to the utility model proposes technological thought, any change done on the basis of technical scheme, each fall within this reality
Within the scope of novel protected；The technology that the utility model is not directed to can be realized by prior art.
