Abstract
The utility model discloses a suspended biomass filling for a biological wastewater processing device, which comprises a hollow plastic ball, block polyurethane carriers, a plastic separating frame, and a mass, the hollow plastic ball is provided with the plastic separating frame in the inner diameter direction, the two sides of the plastic separating frame are respectively provided with a block polyurethane carrier, each block polyurethane carrier is provided with a through hole vertical to the plastic separating frame, and the mass is arranged between the lower of the through hole of the block polyurethane carrier and the inner wall of the hollow plastic ball. The periphery of the block polyurethane carrier used by the utility model is in a zigzag, has large specific surface area, thus favoring the attachment and the growth of the microorganism; the two block polyurethane carriers are separated by the plastic separating frame, thus preventing the block polyurethane carriers from deformation and extrusion generated by bearing buoyancy long term, improving the gas-liquid mass transfer effect, and prolonging the service live; the mass adjusts the specific weight of the filling, to lead the filling to be in a suspension state when in aeration, and lead the cross sections of the block polyurethane carriers to be in a state parallel to the horizontal surface, thereby achieving optimal water distribution and gas distribution effects.
Description
Technical field
The utility model belongs to technical field of waste water processing, relates in particular to a kind of suspended biological filler that is used for the biological effluent treatment device.
Background technology
It is various to have the used filling kind of biological effluent treatment device now, and the fixed filler of typing that early occurs is arranged, and mainly is the honeycomb filler; The suspension type filler that extensively adopts is at present arranged, as soft-filler, semi soft packing, elastic solid filler, combined packing etc.; The suspended biological filler that continues to bring out is arranged, as urethane filler, baton round floating stuffing etc.
The fixed filler of finalizing the design is used in early seventies, is characterized in, under situation about not stopping up, treatment effect is more stable, and specific surface area is 200m
2/ m
3About, work-ing life is longer, is generally 5～8 years.But such filler is very high to water distribution, the inhomogeneity requirement of gas distribution, demoulding difficulty easily takes place, thereby cause obstruction.In the use, it is found that when organic substrate concentration was high, the honeycomb filler was easy to stop up, in case stop up, its processing efficiency sharply descends, the serious structures of breaking-up even.Simultaneously, its cost is higher.
The suspension type filler results from early eighties, and still among continuous development, present water treatment field is most widely used so far.This class filler is perfect through improvement progressively, high life reach 5～10 years, and cost is moderate, and is the most competitive on the current market.Wherein, soft-filler comes out the earliest, its principal feature is that theoretical specific surface area is big, biofilm demoulding effect better, do not stop up, but its actual effective ratio area is less.
The characteristics of comprehensive above filler, people develop combined stuffing again, and it has brought into play the advantage of medium-soft and soft-filler to a certain extent, the suitable waste water that biodegradability is relatively poor and concentration is lower.But the manufacturing of existing combined stuffing is normally by realizing at the outer rim colligation soft fiber of semi soft packing, though its specific surface area is than semi soft packing height, work-ing life is shorter than semi soft packing, and because to a certain degree clustering phenomena still can appear in soft fiber after operation for some time, thereby reduced the specific surface area of such filler, caused the processing power of biological effluent treatment device to descend or the effluent quality variation.
Existing suspended biological carrier is based on baton round floating stuffing and urethane filler.The plastic filler specific surface area is little, the biofilm weak effect; Urethane filler reference area is big, but the easy accumulation of long-time running is agglomerating, influences the water outlet effect; Other has the built-in urethane carrier of baton round filler, has alleviated urethane to a certain extent and has piled up agglomerating shortcoming, but still can't solve the clustering phenomena of urethane carrier in the baton round, influences wastewater treatment equipment long-time running effect.
Summary of the invention
The purpose of this utility model is to be the suspended biological filler that is used for the biological effluent treatment device that a kind of specific surface area height, long service life, moderate cost is provided, can improves wastewater treatment ability and stable effluent quality.
The suspended biological filler that is used for wastewater treatment comprises hollow baton round, massive polyurethane carrier, plastics separation frame, mass, hollow baton round interior diameter direction is provided with the plastics separation frame, the both sides of plastics separation frame are respectively equipped with the massive polyurethane carrier, the massive polyurethane carrier is provided with and the vertical through hole of plastics separation frame, is provided with mass between the through hole below of massive polyurethane carrier and the hollow baton round inwall.
The periphery of described massive polyurethane carrier is the polygonal structure of indention.Described massive polyurethane carrier is the massive polyurethane carrier of handling through networking with netted channels and collaterals structure.The sphere of described hollow baton round is plastics channels and collaterals structures, is welded to form by two hemisphere.Described plastics separation frame is made up of two identical plastics stripper loops.Described plastics stripper loop is the mutually inserted structure, and 2-6 jack and 2-6 pin are set respectively, is uniformly distributed on the plastics stripper loop, and jack and pin are oppositely arranged.Described mass diameter is greater than massive polyurethane carrier through-hole diameter.Filler proportion after the described suspended biological filler counterweight is 1.05～1.20, and the aeration operation is in suspended state.
The hollow baton round that the utility model is used, sphere are plastics channels and collaterals structure, and percentage of open area is big; The massive polyurethane carrier that uses, the polygonal structure of peripheral indention more helps microorganic adhesion and growth; The massive polyurethane carrier has good gas-liquid mass transfer effect, the plastics separation frame is set simultaneously separates two blocks of massive polyurethane carriers, prevent that massive polyurethane is subjected to buoyancy to produce deformation and extruding conglomeration for a long time, improved the gas-liquid mass transfer effect, prolonged filler work-ing life; The built-in counterweight of hollow baton round is effectively regulated filler proportion, is in suspended state when making padding aeration during water treatment applications all the time; Mass is provided with by the massive polyurethane carrier and firmly is stuck in plastics hemisphere top, regulates massive polyurethane carrier cross-section in the form that is parallel to horizontal plane, reaches better distribute water and air effect.
