Description

A kind of microfauna attachment filler
Technical field
The present invention relates to a kind of filler, be specially filling for sewage treatment.
Background technology
Produce a large amount of mud in municipal sewage treatment process, containing many hazardous and noxious substances in mud, deal with improperly and will cause serious environmental problem.The method of current existing mud decrement mainly comprises molten born of the same parents-recessive growth, uncoupling metabolism, metabolic balance, microorganism predation.The advantages such as wherein microorganism predation technology has pure ecological property, non-secondary pollution, processing costs is low, mud decrement is effective.Microorganism predation technology mainly realizes mud decrement by microfauna to effects such as the picked-up of mud, molten born of the same parents.In the process of sludge predation, a part of mud is absorbed in the mode of food by microfauna, and mud obtains decrement; The part mud then molten born of the same parents of broken wall, with nutritive substance form releases such as carbon nitrogen, reaches the effect of mud decrement by stealth growth.But in the process due to predation, microfauna is extremely responsive to environment, biological density is low, be difficult to the stable dominant population of formation, and under the shock action of current, microfauna is difficult to stable growth and opposing water flow impact pressure.These all strongly limit the application & development of sludge organism predation technology.
At present, what sludge organism predation technology Application comparison was many is by microfauna placing response device, to cause problem and then the mud decrement weak effects such as microfauna biological density is low, growth is unstable like this, if publication number is that in " the deflector type oligochaete sludge decrement reactor " of 1778727, microfauna can only be attached on reactor wall, and be in unbound state, by cause adhesion amount little, cannot stable growth, to the resistivity of water impact, low and then prey ability declines.
Therefore, develop that a kind of biological density is high, microfauna stable growth, microfauna attachment filler that opposing foreign impacts power is strong become the key solving biological sludge predation technology.
Summary of the invention
The present invention be to solve in existing microfauna attachment filler microfauna can not stable growth, biological density is low, causes mud to prey on the technical problem of weak effect, provides a kind of microfauna attachment filler.
Microfauna attachment filler of the present invention comprises carrier, metal grill and support frame composition, described carrier is staggered by filamentary material to weave the reticulation that formed, several metal grills have been horizontally disposed with in described support frame, described carrier is fixed on metal grill upper surface, leaves gap between described carrier and metal grill.
The induction method of above-mentioned microfauna attachment filler is specially:
First the carrier in microfauna attachment filler is put into mud mixture, carrier is made to be in mud moisture interface, utilize the going after profit or gain property of microfauna, the head of microfauna extends to below carrier by the hole of carrier or gap, and afterbody extends to filler top layer and breathes to obtain oxygen.After cultivating 24h, carrier is taken out flushing, washes away the microfauna do not adhered to, how again carrier to be reapposed and again induce in mud mixture, several times so repeatedly.Then carrier is fixed on metal grill upper surface, reinstalls support frame.
Microfauna of the present invention be mingled with band silk earthworm, limnodrilus hoffmeisteri, Limnodrilus hoffmeisteri etc. can the microfauna of sludge predation.
Beneficial effect of the present invention:
1, carrier has certain hole or gap structure, strengthens the stable set of microfauna, ensures that microfauna fully contacts with mud, realizes the efficient predation of mud.Contribute to microfauna apposition growth;
2, described support frame can resist extraneous water flow impact pressure, effectively ensure that the stability of whole filling system structure; The Main Function of metal grill is to carry carrier, slows down the impact of mud to microfauna, realizes the stable growth of microfauna; Draw-in groove plays fixed action, the stability of reinforcing filler system, improves the ability that filling system resists mud collision, for microfauna existence predation provides good environment.
3, microfauna attachment filler of the present invention needs to carry out inducing culture before use, microfauna passes through inducing culture, according to its " going after profit or gain property ", the head of microfauna is extended in sludge blanket downwards by carrier and obtains food, certain gap is left on carrier and metal grill surface, ensure that the fully movement between carrier of the bubble of aerating apparatus, extends bubble residence time, be convenient to microfauna and mud predation is carried out to dissolving oxygen absorption, realize efficient mud decrement effect.
4, multiple layer metal grid is fixed on supporting frame and adds microfauna density in unit volume, improves mud predation efficiency.The more traditional microfauna attachment filler of mud predation efficiency of the microfauna of microfauna attachment filler of the present invention improves more than 30%.
