Abstract
The utility model discloses a hollow short tube membrane filler. The hollow short tube membrane filler is characterized in that a short tube is hollow; one end of the short tube is opened; and the other end of the short tube is sealed or provided with a plurality of micropores. The length of the filler is 4-8 cm; the diameter of the filler is 2-4 cm; the diameter of the micropore on the sealed end is 5-10 mm; and the total area of the holes is 40-60 percent of the section area of the tube. The internal and external surfaces of the short tube are coarse and unpolished, and also are provided with regular and irregular textures. The filler fully plays the advantages of the hollow short tube filler, has a simple structure and a low price, is convenient to machine and use, and also has the functions of the membrane filler for conventional biological processing and the function of preventing sludge from running off and promoting the separating of the sludge and water in the biological processing. The filler has an advantage of creating different microbial growing environments by optimizing the structure form of the filler, thus being beneficial to the diversity of the microbial growth. The oxygen-limited environment can be manually created to optimize the growing environment of heterotrophic bacteria, can be beneficial to the simultaneous nitrification and denitrification, and can be used for improving the sewage treatment effect. The filler is mainly used for water supply or used in bioreactor in sewage treatment.
Description
Technical field
The utility model relates to a kind of hollow short pipe film filler that can build the different microorganisms growing environment.Belong to city water and technical field of sewage.
Background technology
The film filler is as the core of bio-reactor, and filler selection directly influences the microbial growth environment, further changes the water treatment effect.Anoxic and denitrification are to get in touch two notions closely.Under anoxic condition, if there is available carbon source, then mikrobe must carry out denitrification.Nitrobacteria in the microflora is easy to break away from flco and free the existence, or main existence is carried out denitrifying heterotrophic bacteria and then mainly concentrated on flco inside at the skin of flco.When dissolved oxygen was controlled at suitable scope, the nitrobacteria that has been in oxygen condition carried out nitrated, and the heterotrophic bacteria that is in anoxic condition carries out denitrification.At present, it is big that the most fillers in many biological treatment reactors all have specific surface area, be evenly distributed, and easy to be filmed, cost is low, can promote traditional performances such as mud-water separation.But the mikrobe major part of adhering on the filler is present under the aerobic condition, and the mikrobe that anaerobic condition exists down is less, and the microorganism growth environment is single, is unfavorable for synchronous nitration and denitrification, has influenced the performance of biological treatment reactor.Though some filler has been optimized filling-material structure, form is comparatively complicated, makes difficulty, and cost is high, is inappropriate for practical application.Therefore, but need a kind of that propose from the angle of improving the microorganism growth environment and large-scale promotion on the market badly and use new-type filler.
The utility model content
The purpose of the utility model is the defective to above-mentioned existence, proposes a kind of hollow short pipe film filler that can build the different microorganisms growing environment.It has the performance of conventional water treatment filler, and it is few effectively to have overcome conventional biologic packing material microbe species, the limitation of synchronous nitration and denitrification difficulty.
A kind of hollow short pipe film filler is characterized in that: said hollow short pipe film filler is a hollow, an end opening, and the other end sealing or the other end seal and are provided with some micropores at closedend.
Said hollow short pipe film pack length is 4 ~ 8cm, and diameter is 2 ~ 4cm, and the micro-pore diameter that is provided with of sealing is 5mm ~ 10mm, the micropore total area be hollow short pipe film filler section area 40% ~ 60%.
The coarse tarnish of surfaces externally and internally of said hollow short pipe film filler, and with ripple or random lines.
Tubulose can prevent sludge loss and promote mud-water separation; Sealing of one end or closedend are provided with micropore can build the different microorganisms growing environment so that dissolved oxygen presents gradient in the pipe, and filling tube inner opening end is in aerobic environment; Constantly reduce along the journey dissolved oxygen; Closedend is in anaerobic environment, makes filler have multiple environment simultaneously concurrently, helps the variety of microorganism growth; Can carry out synchronous nitration denitrification denitrogenation, help improving processing efficiency.
The coarse tarnish of said short tube surfaces externally and internally, and have ripple or random lines concurrently, help microorganic adhesion, hang film time weak point.
The utility model is with respect to the spherical combined stuffing that waits, and is cheap, makes simple.It has kept the form of conventional tube filler; And be optimized, not only give full play to the advantage of hollow short pipe filler, and overcome its deficiency; Be suitable for and carry out synchronous nitration and denitrification; Build the different microorganisms growing environment simultaneously, microbe species is significantly increased, can effectively improve the water treatment effect.
