Background
The sewage treatment filler is a measure which is taken for discharging sewage into a water body, discharging into a certain water body or reusing the sewage after the sewage is treated by a certain method and reaches certain set standards. The biological membrane process for sewage treatment mainly comprises the processes of a biological filter, a biological rotating disk, a biological contact oxidation tank, a biological aerated filter, a biological fluidized bed and the like, and is characterized in that microorganisms are attached to and grow on the surface of a filler to form a biological membrane, and pollutants are adsorbed and converted by the microorganisms after the sewage is contacted with the biological membrane, so that the sewage is purified.
At present, the well-known biological fillers are soft fillers, elastic fillers and combined fillers, wherein: soft filler: when in use, the fine fiber is easy to harden and lose activity; elastic filler: after a period of use, the central region of the packing is not in sufficient contact with the wastewater, and the efficiency is reduced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that, overcome prior art's defect, provide a cavity biofilm carrier, this kind of biofilm carrier has overcome the filler and has hardened, the central zone is insufficient with the waste water contact phenomenon, effectively improves purification efficiency.
In order to solve the technical problem, the utility model provides a hollow biological filler, including main part and the solid fixed ring of setting at the main part both ends, gu all be connected with fixed rope on the fixed ring, the main part is inside hollow tubular structure, all is equipped with the net hole on the inside and outside surface of main part, and the main part forms for the polyurethane foaming, is provided with the fixed column in the fixed ring, the fixed column passes through threaded connection by first connecting rod and second connecting rod and constitutes, the outer end of first connecting rod and second connecting rod all is provided with the stopper, gu all set up on fixed ring and the main part and supply first connecting rod and second connecting rod male through-hole, fixed rope and first connecting rod or second connecting rod fixed connection.
After adopting above-mentioned structure, compare with prior art, the utility model has the advantages of it is following:
the utility model discloses a hollow filler main part, the surface area of the filler of effective expansion, thereby make in the main part, surface adsorption's microorganism homoenergetic and waste water fully contact, thereby effectively improve purification efficiency, and, because the main part adopts the polyurethane foaming to form, it can harden to have avoided using for a long time the back filler, and service life is improved, and on this basis, when the installation is packed, through-hole on with solid fixed ring aligns with the through-hole in the main part, then pass through the through-hole with first connecting rod and second connecting rod inside inserting the main part, and connect the inner of first connecting rod and second connecting rod, thereby with solid fixed ring and the firm connection of main part, can connect fixed rope on the fixed column, such structure makes the filler fixed firm more firm.
As an improvement, a connecting hole is formed in the inner end of the first connecting rod, an internal thread is arranged in the connecting hole, and an external thread matched with the internal thread is arranged on the outer wall of the inner end of the second connecting rod, so that the first connecting rod and the second connecting rod are connected through the connection of the internal thread and the external thread, and the connection through the thread is very convenient, simple and reliable.
As an improvement, the fixing rope comprises a first part connected with the first connecting rod or the second connecting rod and a plurality of obliquely arranged branch parts, one end of each branch part is connected with the fixing ring, the other end of each branch part is connected with the first part, and the branch parts are uniformly distributed along the circumferential direction of the fixing ring, so that the filler is fixed more stably and firmly.
As a modification, the main body has an outer diameter of 150mm, an inner diameter of 120mm, a length of 2000mm and a thickness of 15 mm.
As an improvement, the width of the grid holes is 4-5 mm.
