Technical Field

The invention belongs to the technical field of sewage treatment, and particularly relates to a novel special MBBR filler.

Background

The MBBR filler is a microbial carrier applied to an MBBR process and mainly provides an environment suitable for growth of microorganisms.

The MBBR filler is a bioactive carrier, adopts a scientific formula, is formed by fusing a plurality of trace elements which are beneficial to the rapid attachment and growth of microorganisms in a high polymer material according to different sewage properties and modifying and constructing through a special process, and has the advantages of large specific surface area, good hydrophilicity, high bioactivity, rapid film formation, good treatment effect, long service life and the like.

The core of the MBBR technology is a biological carrier and an operation control technology;

the biological carrier is a product which is closely combined with the biology in materials;

the existing MBBR biological filler material in the market of China takes High Density Polyethylene (HDPE) as a raw material, the density of the MBBR biological filler material is higher than that of low density polyethylene, but the hardness of the MBBR biological filler material is less than that of the low density polyethylene, so that the service life of the biological membrane filler material in the application process of a sewage treatment plant is shortened, and the depreciation rate and the breakage rate are high. China has a plurality of sewage treatment plants in the prior MBBR process, because the running time is long, the defect is designed on the biomembrane packing tank body at that time, the packing fluidization state is extremely poor, the sewage treatment plants with most of the packing accumulation have no need to carry out the next step on the phenomenon, the cleaning is troublesome, if the cleaning is carried out, the operation is stopped, and the time and the money are consumed.

Disclosure of Invention

The invention aims to provide a novel MBBR special filler which can improve the nitrogen and phosphorus removal effect of a sewage treatment system.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a novel special filler of MBBR, this novel special filler of MBBR includes the casing, the casing is the tubulose, the inside a plurality of faceted pebbles that are equipped with of casing, it is a plurality of the faceted pebble falls into a plurality of hexagonal holes with the casing is inside, the inside crest line that still is equipped with of casing, the crest line is located the inside 115 that are provided with of casing altogether.

Preferably, the shell has a diameter of 25mm, a thickness of 10mm and a surface area of 800 square meters per m for weight transfer.

Preferably, the hexagonal holes are 37 in total.

Preferably, the ridge is located the hexagonal downthehole wall, every all set up on the alternate surface of hexagonal downthehole wall the ridge.

Preferably, the outer wall of the housing is corrugated.

Compared with the prior art, the invention has the beneficial effects that the grain size of the nano Fe3O4 in the product is 30nm, the surface roughness is large, the film hanging speed is higher than that of the filler made of common High Density Polyethylene (HDPE), meanwhile, the surface potential of the filler is positive charge, the filler is suitable for the attachment growth of microorganisms, the porosity of the filler reaches 94% in design, the fluidization system effect is good, the aeration is arranged at the bottom, an interception screen is designed at an outlet to prevent the filler from being accumulated in a large area, the filler is designed to have 37 apertures, 25mm in diameter and 10mm in thickness, and 115 ridges are arranged inside, when the filler is contacted with water, the hydraulic shearing effect is achieved, the flow state effect of water flow and air flow is good, the density of the filler reaches 0.95 ~ 0.976g/cm, the fluidization state can be realized by smaller aeration or stirring, the service life of the filler is far longer than that of the filler made of the common High Density Polyethylene (HDPE), the service life of the filler can reach 50 years, the breakage rate is lower, the cleaning and the replacement process is simpler and convenient, the filler is independently designed in terms of the performance, and the comprehensive stirring/aeration tank is good according to.

Detailed Description

In order to further understand the contents, features and effects of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings.

The novel MBBR special filler of the embodiment of the invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1, this novel special filler of MBBR includes casing 1, casing 1 is the tubulose, 1 inside a plurality of faceted pebbles 3 that are equipped with of casing, it is a plurality of faceted pebble 3 falls into a plurality of hexagonal holes 2 with 1 inside of casing, 1 inside still is equipped with crest line 4 of casing, crest line 4 is located 1 inside of casing and is provided with 115 altogether.

Specifically, the diameter of the shell 1 is 25mm, the thickness is 10mm, and the surface area is 800 square meters per m for planting.

Specifically, the hexagonal holes 2 are 37 in total.

Specifically, crest line 4 is located hexagonal hole 2 inner walls, every all set up on the alternate surface in hexagonal hole 2 inner walls crest line 4.

Specifically, the outer wall of the shell 1 is corrugated.

In conclusion, the filler is designed to have the aperture of 37, the diameter of 25mm and the thickness of 10mm, and the internal 115 ridges are added, so that when the filler is contacted with water, a water conservancy shearing effect is achieved, the flow state effect of water flow and air flow is good, the density of the filler reaches 0.95 ~ 0.976.976 g/cm, and the fluidization state can be realized by small aeration or stirring.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
