Abstract
The invention discloses a kind of filter devices for handling surface rain runoff, and including filter material layer and bed course, wherein filter material layer includes sand, volcanic sand, coconut palm chaff, sand, volcanic sand, coconut palm chaff mix, hydraulic loading is no more than 30m3/m2.d, and filtrate layer thickness is more than 50cm, and bed course is located at below filter material layer, rainwater is flowed by upper epidermis, bottom is flowed out, and collecting pipe is located in bed course, and bed course is made of gravel, 5 15mm of gravel diameter, thickness can be 20 30cm.The drawbacks of present invention can overcome the filtration system of traditional single filter material that can only remove water part pollutant, filtrate can provide existence place for plant and microorganism, strengthen media filtration effect, using technical solution of the present invention, SS removal rates 85% or so in runoff rainwater, ammonia nitrogen 35% or so, COD70% or so, total phosphorus 50% or so.
Description
Technical field
The present invention relates to a kind of filter device, particularly a kind of filter device for handling surface rain runoff.
Background technology
With the quickening of urbanization process, the ratio shared by the waterproof region area in the cities such as road, bridge, building is more next
Bigger, the run-off of Urban Rain has increased to 55% after exploitation via 10% before city development.Rainfall elution air,
It washes away road, building etc. and carries the pollutants such as large amount of organic, pathogen, heavy metal, finish, suspended solid later, most
Enter surface water, underground water and urban rivers and lakes water system eventually, Urban Water Environment is caused to pollute, ecosystem health is unbalance.At present
The non-point pollution problem that Urban Rain rainwash is brought is increasingly sharpened.The concept of rainwater biofiltration proposes by American,
Relatively broad application is obtained in rainwater treatment at present.Its core is to collect runoff rainwater by forms such as grooves, works as rainwater
Filtration system is flowed through, pollutant is removed under filtering, osmotic absorption and biodegradable synergy, reaches control rainwater diameter
Flow the purpose of pollution.
Invention content
Goal of the invention：The object of the present invention is to provide a kind of filter device for handling surface rain runoff, the filter devices
Existence place can be provided for plant and microorganism, strengthen the filter effect of filtrate, overcome traditional filtration system that can only filter
The drawbacks of water part pollutant.
Technical solution：The present invention relates to a kind of filter device for handling surface rain runoff, mainly by filter material layer and bed course
It forms.The filtrate layer thickness is more than 50cm, is made of husky, volcanic sand and coconut palm chaff；The volume group of filter material layer sand, volcanic sand and coconut palm chaff
Become：Husky volume ratio accounts for 60-85%, volcanic sand 5-20%, coconut palm chaff 10-25%.Wherein grains of sand diameter 0.3-0.5mm, the volcano grains of sand
Diameter 0.3-0.5mm, coconut palm chaff grain size 0.1-0.3mm.Bed course is made of gravel, thickness 20-30cm, grain size of gravel 5-15mm；It is blind
Pipe is set in bed course, facilitates the rainwater collected after filtering.
Above-mentioned filter material layer is made of sand, volcanic sand and coconut palm chaff, and three is sufficiently mixed, sand not water conservation in itself, it is impossible to give
Plant storage moisture.Coconut palm chaff is cocoanut husk fiber dust, is coconut by-product or waste after processing.It is from cocoanut husk
A kind of pure natural organic matter medium under coming off in fiber process.Coconut palm chaff after through processing is very suitable for cultivating
Plant.It can ensure sufficient the air gap while moisture is supplied, and be conducive to the growth of plant.Volcanic sand refers to
Pyroclastic tephra similar in thickness and the grains of sand.Volcanic sand mainly makees base manure, the more micropores of rough surface, these features particularly suitable for
Microorganism grows on its surface, breeding, forms biomembrane.Volcanic sand contains activated carbon, and the high surface area that porosity generates is training
The good hotbed of bacterium in water is supported, and its surface is positive charge, be conducive to microorganism fixation growth, hydrophily is strong.
Advantageous effect：The present invention has preferable section of dirty effect, and filtered experiment shows that surface rain after filtering, goes out
Water water quality is preferable, SS removal rates 85% or so, ammonia nitrogen 35% or so, COD70% or so, total phosphorus 50% or so.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.

Rainfall duration 35min, hydraulic loading for 7m3/m2.d after filtering, SS removal rates 85% in runoff rainwater, ammonia nitrogen 33%,
COD78% or so, total phosphorus 50%.
Embodiment 2
The present invention is laid with Mr. Yu city arterial highway side, long 40m, wide 5m, filtrate layer thickness 50cm, wherein husky volume ratio is
75%, volcanic sand volume ratio is 15%, and coconut palm chaff volume ratio is 10%, and cushion thickness 30cm, 1 hour precipitation is 1 millimeter, rainfall
55min, hydraulic loading 2m3/m2.d are lasted, after filtering, SS removal rates 90% in runoff rainwater, ammonia nitrogen 30%,
COD73%, total phosphorus 52%.
