Description
Technical field
The present invention relates to water treatment biological carrier, be meant suspended biological carrier that a kind of and microbial bodies adapts and preparation method thereof more specifically.
Background technology
Suspended biological carrier is one of existing biological sewage treatment important materials, and the suspended biological carrier of practical application at present is more, is bringing into play important effect in sewage disposal.In the research of suspended biological carrier, carrier structure is one of research focus, a kind of suspended biological carrier of regulating proportion is disclosed as Chinese patent 02218096.6, connect to form by circular arc retaining plate, circular arc wing plate, fixed ring, proportion adjustable pipe, set collar, specific surface area is bigger, can regulate proportion, freely suspends in sewage, be fluidization under the effect of aeration in biological contact oxidation pond, processing efficiency is greatly improved.But still come with some shortcomings: (1) makes smooth surface because this retaining plate is a slab construction, and the serrated slot on wing plate surface is a single direction in addition, so be not easy to biological attachment; (2) because of the wing plate plane does not have hole, hydrodynamic performance is not good, causes on the carrier nutrition and oxygen to supply with insufficient; (3) owing to will regulate proportion by structure, make complex structure, manufacturing cost is higher.
Chinese patent 99253300.7 discloses a kind of spindle-type suspended biological carrier, is made up of rack, guipure, filler, axial cord, and it is little to have a volume, advantage such as specific surface area is big.But also come with some shortcomings: the hole pattern structure of (1) rack and guipure is blocked by microorganism easily, makes the filler of inner face and internal space thereof be difficult to make full use of; (2) attaching surface mainly relies on the filling surface of inner face, and the structural frames of rack and guipure is more tiny, does not obtain utilizing.
Summary of the invention
The objective of the invention is to the shortcoming that exists at existing suspended biological carrier, provide that microbial bodies adapts in a kind of and the sewage, simple in structure, it is convenient to prepare, and cost is low, hydrodynamic characteristic good suspension bio-carrier during use.
The objective of the invention is to be achieved through the following technical solutions:
The preparation method of the suspended biological carrier that a kind of and microbial bodies adapts is as follows,
(1) adopt polymer-extruded machine, nozzle is equipped with the cross section and has groove, and the mould of rough inner surface;
(2) extrude the cross section by this mould projection, shaggy thread polymeric acceptor are arranged;
(3) there are projection, shaggy thread polymeric acceptor to twine the suspended biological carrier of any face shaping that forms irregular space through spiral by some cross sections.It is 1～3mm that suspended biological carrier adopts the silk footpath of thread polymeric acceptor; The screw diameter of selecting for use when thread polymeric acceptor spiral twines is 6～8mm, and pitch is 4～7mm.
The suspended biological carrier of the present invention's preparation, there are projection and surface irregularity in the cross section of its filament, is twined by thread polymeric acceptor and forms any face shaping of random layer.
The structure of the suspended biological carrier that this and microbial bodies adapts can be individual layer or bilayer or multilayered structure; Face shaping is generally cube, also can be cylindrical or spherical.
The present invention compares with existing suspended biological carrier has following advantage:
(1) space structure of carrier of the present invention and microbial bodies are complementary, and are fit to the apposition growth of the microorganism of each population, make that the accumulative microbe species is many on the carrier, and all contaminations is all had Degradation, and be more thorough to sewage disposal.
(2) effective surface area of carrier of the present invention is big, can adsorb a large amount of microorganisms and form stable, ecological abundant microbial film, has improved the degradation capability of microbial film to pollutent in the sewage.
(3) carrier winding arrangement, hydrodynamic characteristic is good, each surface of carrier is direct and gas-to-liquid contact in BAF, embodied good hydrodynamic characteristic, make biomembranous nutrition and oxygen supply with fully, improve the biological activity of microorganism greatly, improve microbial film thereupon sewage treatment effect.
(4) the old microbial film on the carrier can leave carrier more up hill and dale under the ballistic effect of Liquid Flow, does not block bio-carrier.
(5) carrier is entwined by the filament spiral, and is simple in structure, and preparation is easy, and cost is low, easily applies.
