Description
Technical field
The utility model discloses a kind of filter tank, is related to Water purification technical field, specifically a kind of high-efficiency double-layer filter
Expect filter tank.
Background technology
Filtering generally refers to suspended impurity in filter material layer trap water, so that water obtains the technical process of clarification.Ran
Cheng Zhong, for single bed filter after backwash, the particle diameter of top layer filtrate is small, and retention suspended particulate amount is more, and lower floor's particle diameter is larger
Filtrate tends not to play a role completely.After especially filtering a period of time, the hole between the filtrate of top layer is gradually blocked, even
Mud film is formd, filtration resistance is increased severely, delivery turbidity rise, filter process is forced to stop, and it is outstanding to result in lower floor's filtrate retention
Floating particles effect is not fully exerted far away, and filter bed overall utilization rate is low.Further, since existing filtering centre drainage ditch is deposited
Only played a role when backwashing water outlet, but making filter tank integral surface utilization rate not high.And existing filter tank is severe in burst
Under water quality situation, often need to reduce turbidity by increasing ozone dosage or increasing substantially flocculant dosage, but cause pair
The generation of product bromate, or waste a large amount of chemical agents.The utility model provides a kind of high-efficiency double-layer filter material filter pool, passes through
Coal sand double-layer filter material, the pollutant carrying capacity in filter tank is improved, meanwhile, drainage ditch among existing filter tank is removed, the whole equal energy in filter tank
Filtrate is covered, in identical floor space, adds filter area.Can also or leading portion sedimentation basin water outlet severe in influent quality
When turbidity is high, to ensure filter tank standard water discharge, tiny flocculation dosing structure is set up, will be tiny in water by adding flocculant in advance
Particle flocculates again, then is removed by filter.
Utility model content
The utility model provides a kind of high-efficiency double-layer filter material filter pool, it is possible to increase the filter area and pollutant carrying capacity in filter tank,
And effluent quality can be ensured when influent quality deteriorates.

The beneficial effects of the utility model are：
The utility model covers coal sand double-layer filter material in the pond body of filter tank, and upper strata particle diameter is more than lower floor's particle diameter, grain during filtering
The larger particle in footpath is retained on upper strata, and the less particle of particle diameter removes in lower floor's filter material layer, improves the dirty energy of receiving in filter tank
Power；And the thickness of double-layer filter material is provided, while effluent quality is ensured, filter cycle is improved, further may be used
Reduce backwash frequency；
Meanwhile in terms of the type of pond, the middle drainage ditch in existing V-type pond filter tank is removed, whole filter tank can cover filtrate,
In identical floor space, filter area is added；
And it is severe in influent quality or when leading portion sedimentation basin delivery turbidity is high, to ensure filter tank standard water discharge, intaking
Jing Chu sets up chemical feed pipe and agitating device, adds flocculant by secondary, fine particle in water is flocculated again, then pass through filtering
Remove.Therefore the utility model mainly designs more than, greatly improves filter tank utilization rate, and quadratic micro-flocculation work can be selected
Skill, by adding flocculant, fine particle is flocculated into floccule again, removed by the filtration of filtrate, make water outlet water
Matter is further enhanced.
