Description
Technical field
The invention belongs to water treatment device field, particularly relate to a kind of modification foam bioreactor device.
Background technology
Modification foam has larger specific surface area and stronger absorption property, and therefore, this research selects modification foam as main stuffing.
Foam (pulnice) is a kind of extrusive rock in volcanic rock (lava) material, primarily of volcanic glass, mineral composition.During volcanic explosion, a large amount of volcanic gases produced in magma form foam, and foam cooling subsequently, gas " is sealed up for safekeeping " in foam.Bubble in foam accounts for more than 70% of rock cumulative volume, only has very thin volcanic glass and mineral between bubble, on thus can bubbling through the water column.Foam is similar to slag outward, and porous surface becomes cellular, and color is light, mostly is white, canescence or beige.Foam is a china natural resources amount class nonmetallic minerals large and distributed more widely, reserves are only second to Italy, Greece, occupy third place in the world, the place of production relates to the provinces and regions such as Heilungkiang, Jilin, Liaoning, Inner Mongol, Shanxi, Xinjiang, Yunnan, Hainan, be widely used in the numerous areas such as industry, agricultural, in chemical industry, be used as the carrier of filtering medium, siccative, catalyzer, weighting agent and agricultural insecticide and the control-released agent of fertilizer, also directly can be used as material of construction.
In recent years, preliminary study is carried out to the absorption property of foam and application thereof both at home and abroad, found that foam has unique air hole structure and good adsorptive power.WhithanA.G. wait and found by foam immersion float test, though the rate of water absorption of different densities, size and place of production foam has notable difference, the interconnection of its internal porosity is better, therefore has good mass transfer effect.Bahri Ersoy etc. have studied the foam originating from Turkey Tatvan area, and find that its thermostability is up to 900 DEG C, because size differs, pore size distribution is between 0.05um ~ 2mm, and its specific surface area and overall porosity increase with the reduction of particle diameter.Maria Rosaria Panucci etc. study discovery, and foam is to Cd in the aqueous solution
2+clearance and Cd
2+starting point concentration become remarkable positive correlation.The research such as Fethiye Gode etc., Mustafa Yavuz also shows, foam is to heavy metal Cu in the aqueous solution
2+, Cr
3+there is better clearance, and can 80% be reached when pH=8.Feryal Akbal studies discovery, and foam has obvious adsorption to the methylene blue in the aqueous solution and Viola crystallina, effectively can remove water body chroma.Song Xiuhuan etc. are by more several non-metallic minerals surface-area and hydrogen sulfide adsorption experimental result, find in physisorption, by weak order being by force: diatomite > medical stone > clinoptilolite > foam.Chemisorption mainly levels of transition metals contained by mineral plays a leading role to adsorptive power, is followed successively by the adsorptive power of hydrogen sulfide: foam > diatomite > medical stone > zeolite.
Summary of the invention
The object of this invention is to provide a kind of modification foam bioreactor device, improve the adsorptive power of foam, the adsorptive power of sorbent material provides high concentration of substrate for light-catalyzed reaction, improves light-catalyzed reaction speed, and pollutent is purified completely the absorption of the by product of reaction.
The present invention adopts following technical scheme to achieve these goals:
A kind of modification foam bioreactor device, comprises anaerobic pond, aeration tank and combined-flow hay tank, is filled with soft-filler layer in anaerobic pond, arrange modification foam floating stuffing in aeration tank; Lower end water inlet on the left of anaerobic pond, the flat mouth weir water outlet of upper end, right side; Lower end water inlet on the left of aeration tank, the V-notch weir water outlet of upper end, right side, bottom arranges aeration plate; The upper end of combined-flow hay tank is feed-water end, and feed-water end arranges latticed water distributor, and the water outlet of ring-type collecting gutter is established in bottom, inner filling multilayer modification foam filtrate, and establishes multi-layer porous flap.
Described soft-filler is worked out by multi-layer fiber silk, and soft-filler is single is of a size of 980 mm × 5, mm × 500 mm, specific surface area 160-180 m
2/ m
3, lower end system plummet is anchored at the bottom of pond, and upper end is cut into elongated strip, is suspended in pond.
In described aeration tank, floating stuffing is modification foam, density and water close, can be suspended in water body after attached biological film, particle diameter 0.5 ~ 1mm.
Described combined-flow hay tank filling multilayer modification foam filtrate, particle diameter is respectively 2-4mm, 5-7mm, 10-16mm and 30-40mm from top to bottom, and Thickness Ratio is 1:3:6:9.
One flap is set along the every 20cm of elevation in described combined-flow hay tank, and is staggeredly fixed on the left and right sides, flap is established 2-3 capable diameter 5mm circular hole, pitch of holes 10mm.
Beneficial effect of the present invention: the adsorptive power that improve foam, the adsorptive power of sorbent material provides high concentration of substrate for light-catalyzed reaction, improves light-catalyzed reaction speed, and pollutent is purified completely the absorption of the by product of reaction.The foam resource of exploitation China's abundant, improves wastewater treatment efficiency, reduces filler cost.
