Description
Technical field
The invention belongs to water treatment facilities field, particularly relate to a kind of modified foam bioreactor device.
Background technology
Modified foam has bigger specific surface area and stronger absorption property, and therefore, this research selects modified foam to make
For main stuffing.
Foam (pulnice), is a kind of effusive rock in igneous rock (lava) material, mainly by volcanic glass, mineral group
Become.During volcano eruption, a large amount of volcanic gases produced in magma form foam, subsequently foam cooling, and gas " is sealed up for safekeeping "
In foam.Bubble in foam accounts for more than the 70% of rock cumulative volume, volcanic glass the most very thin between bubble and mineral, because of
And on can bubbling through the water column.Being similar to slag outside foam, porous surface becomes cellular, and color is light, mostly be white, canescence or
Person's taupe.Foam is the class nonmetallic minerals that china natural resources amount is big and distributed more widely, and reserves are only second to Italy, Greece,
Occupying 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, extensively should
For the numerous areas such as industrial, agriculture, chemical industry is used as filtering agent, drier, catalyst, filler and agricultural kills
The carrier of worm agent and the controlled release agent of fertilizer, it is possible to be directly used as construction material.
In recent years, absorption property and application thereof to foam have carried out Primary Study both at home and abroad, find that foam has uniqueness
Air hole structure and good adsorption capacity.WhithanA.G. wait and found by foam immersion float test, different densities, big
Though little and place of production foam rate of water absorption has notable difference, but the interconnection of its internal porosity is preferable, therefore has very well
Mass transfer effect.Bahri Ersoy etc. have studied the foam originating from Turkey Tatvan area, finds that its heat endurance is up to
900 DEG C, because particle size differs, pore-size distribution between 0.05um～2mm, its specific surface area and overall porosity subtracting with particle diameter
Little and increase.Maria Rosaria Panucci etc. study discovery, and foam is to Cd in the aqueous solution2+Clearance and Cd2+At the beginning of
Beginning concentration becomes notable positive correlation.The research such as Fethiye Gode etc., Mustafa Yavuz also indicates that, foam is to weight in the aqueous solution
Ni metal2+、Cr3+There is preferable clearance, and when pH=8 up to 80%.Feryal Akbal studies discovery, and foam is to water-soluble
Methylene blue and crystal violet in liquid have obvious suction-operated, can effectively remove water body chroma.Song Xiuhuan etc. are by the most several
Nonmetallic mineral surface area and hydrogen sulfide adsorption experimental result, find in physisorption, by weak order being by force: diatom
Soil ＞ medical stone ＞ clinoptilolite ＞ foam.Chemisorbed is mainly levels of transition metals contained by mineral and plays adsorption capacity leading
Effect, is followed successively by the adsorption capacity of hydrogen sulfide: foam ＞ diatomite ＞ medical stone ＞ zeolite.
Summary of the invention
It is an object of the invention to provide a kind of modified foam bioreactor device, improve the adsorption capacity of foam, inhale
The adsorption capacity of attached dose provides high concentration of substrate for light-catalyzed reaction, improves light-catalyzed reaction speed, and by the pair of reaction
Product absorption makes pollutant be fully cleaned up.
The present invention adopts the following technical scheme that to achieve these goals
A kind of modified foam bioreactor device, including anaerobic pond, aeration tank and combined-flow filtering tank, fills out in anaerobic pond
There is soft-filler layer, aeration tank arranges modified foam floating stuffing；Lower end water inlet on the left of anaerobic pond, flat mouth weir, upper end, right side goes out
Water；Lower end water inlet on the left of aeration tank, the triangular-notch weir water outlet of upper end, right side, bottom arranges aeration plate；The upper end of combined-flow filtering tank is
Water inlet end, water inlet end arranges latticed water distributor, and bottom sets ring-type collecting gutter water outlet, internal filling multilayer modification foam filtrate,
And set multi-layer porous flap.
Described soft-filler is worked out by multi-layer fiber silk, and single a size of 980 mm × 500 mm of soft-filler ×
5 mm, specific surface area 160-180 m2/m3, 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 modified foam, and density is close with water, can be suspended in water body after attached biological film
In, particle diameter 0.5 ~ 1mm.
Described combined-flow filtering tank filling multilayer modification foam filtrate, particle diameter from top to bottom be respectively 2-4mm, 5-7mm,
10-16mm and 30-40mm, thickness is than for 1:3:6:9.
One flap is set along the every 20cm of elevation in described combined-flow filtering tank, and staggered is fixed on the left and right sides, on flap
If 2-3 row diameter 5mm circular hole, pitch of holes 10mm.
Beneficial effects of the present invention: improve the adsorption capacity of foam, the adsorption capacity of adsorbent is that light-catalyzed reaction carries
For high concentration of substrate, improve light-catalyzed reaction speed, and the accessory substance of reaction is adsorbed and makes pollutant be fully cleaned up.Exploitation
The foam resource of China's abundant, improves wastewater treatment efficiency, reduces filler cost.
