Description
Technical field
The present invention relates to water treatment biological carrier, be meant the suspended biological carrier that a kind of material and microbe species and habit adapt more specifically.
Background technology
Suspended biological carrier is being brought into play important effect in biological sewage treatment, the suspended biological carrier of practical application at present is more, and most of bio-carrier products have been done a lot of improvement in configuration aspects, and improves less relatively to the carrier material.Further investigation to suspended biological carrier now shows, the material of bio-carrier directly influences the tack of bio-carrier to microorganism, some researchs improve the material of bio-carrier, the plastic filler on a kind of hydrophilic elastic surface is disclosed as Chinese patent 01129834.0, material is by common plastics, water-soluble high-molecular material, inorganic powders etc. mix to be formed, show good hydrophilicity in actual applications, microorganism colonization speed and intensity in the water treatment system have been improved, and for example Chinese patent 03150250.4 discloses a kind of microbial dry powder that added in material, the bio-carrier of active sludge dry powder, strengthen the biological activity of carrier, can shorten the Start-up and Adjustment time.These researchs show that further the carrier material reaches wastewater treatment efficiency important influence in reactor to the carrier biofilm.
But also there is following weak point in existing suspended biological carrier material research: (1) material selects not consider with combination the different sorts of microorganism in the sewage, thereby existing bio-carrier can not adsorb diversified microbial population in the sewage, can not dispose of sewage more up hill and dale; (2) material distributes singlely, does not have spatially to be interspersed according to the habit of microorganism different population, and spatially utilization ratio is not high to make material; Though patent 03150250.4 described bio-carrier has added microbial dry powder, the different classification of life habit according to microbial population are not added on different zones, thereby can not adsorb microorganism on multiple populations effectively.
Summary of the invention
The objective of the invention is to the shortcoming that exists at existing suspended biological carrier, provide that microbial diversity suits mutually in a kind of material and the sewage, material spatial distribution and the mutually unified suspended biological carrier of different microorganisms life habit.
Technical scheme of the present invention is as follows:
The suspended biological carrier that a kind of material and microbe species and habit adapt, it is characterized in that: the material diversity of suspended biological carrier be interspersed, specifically be meant: (1) suspended biological carrier is formed an element body by outside material ring, middle material ring, inner materials ring and steady arm, wherein outside material ring, middle material ring, inner materials ring connect by the radial support bar, get a plurality of element bodies, around one of them fixing axle center of steady arm, evenly be provided with and circumferentially support the three-dimensional vesicular structure of formation by circumferential steady arm; (2) polymerizable material of inner materials ring surface spraying anaerobion dry powder and inorganic powder, the double oxygen animalcule dry powder of polymerizable material surface spraying and the inorganic powder of middle material ring, the polymerizable material surface spraying aerobic microbiological dry powder and the inorganic powder of outside material ring, steady arm polymerizable material surface spraying inorganic powder.
Above-mentioned element body evenly is provided with and is meant, an element body is set every 10～30 °, and is circumferentially supported by circumferential steady arm, has constituted the suspended biological carrier of a three-dimensional vesicular structure.
Anaerobion dry powder is to contain Clostridium, Bacteroides, genus bifidobacterium, Corynebacterium lactobacillus, streptococcus, Flavobacterium, Escherichia, Aerobacter, micrococcus sp to close the powder that the anaerobic sludge drying and grinding of pseudo-Monas, methagen, methane coccus spirobacteria, methane coccus, sarcina methanica forms.
The oxygen animalcule dry powder of holding concurrently is that the aerobic-anaerobic microbe drying sludge that contains Bacillus proteus, pseudomonas, micrococcus, genus bacillus grinds the powder that forms.
Aerobic microbiological dry powder is to contain to give birth to the moving glue bacterium of branch, sphaerotilus natans bacterium, white Bei Shi thiobacterium, moving glue bacterium, thiobacillus, fungi, algae, protozoon, metazoal aerobic microbiological drying sludge and grind the powder that forms.
Inorganic powder is to contain the powder that at least a uniform mixture in bodied ferric sulfate, magnesiumcarbonate, active silicic acid, SODIUMNITRATE, saltpetre, ammonium sulfate, the silicon oxide is worn into.
The present invention compares with existing suspended biological carrier has following advantage:
(1) carrier material diversity configuration, it is the different sorts of considering microorganism, in the different material of different area configurations, form different microbial films in different zones, can bring into play the advantage of specific pollutants in the degradation of sewage of each microbial population to greatest extent, can finish the anaerobic and aerobic of sewage simultaneously and handle, separately multiple pollutant in the sewage be handled simultaneously, handle more thorough.
(2) being interspersed of carrier material is the zone difference different in the space, and be unified mutually with the required living environment of the microorganism of different population, gives full play to the different population microbic activity, increases the utilization ratio of material on the carrier space.
(3) microbial dry powder and the inorganic powder of material surface spraying, have stronger close microorganism property, can very fast biofilm at the biofilm initial stage, in the old film rear surface that comes off pit is arranged, convenient fresh attached growth of microorganisms makes bio-carrier in use keep stable wastewater treatment efficiency always.
(4) this bio-carrier preparation method is easy, and cost is lower, and is easy to use, and effect obviously is better than other multiaspect hollow ball, cascade ring carrier, is easy to apply.
