Maximize the effect by using special chemical fibers.
Using a variety of manufacturing methods and a variety of chemical
fibers to produce a full range of biological contact materials, in
order to deal with wastewater of different concentrations and water
quality, has been widely used in river ecological restoration,
chemical, textile, electronics, food and other industry wastewater
treatment.It can stably
maintain microorganisms with slow proliferation rate such as
nitrifying bacteria and denitrifying bacteria. At the same time,
the peeling of the attached microorganisms is continuous rather
than concentrated, and there is no phenomenon that the water
quality is affected by the biofilm shedding.Use high-efficiency
food chains attached to biological ropes to reduce the amount of
excess sludgeThe treatment of water quality is stable.Simple
It can completely correspond to wastewater treatment with large
load changes.It can be used stably for a long time (generally more
than ten years), and the efficient treatment effect makes it
achieve the best price/performance ratio.
The bio cord filter media is in the form of a rope, which is first
fixed on the frame and then placed in a biological reaction tank.
Fix the upper and lower ends of the bio cord filter media on the
frame. The standard is 10cm between the vertical and horizontal.
Therefore, the installation amount of the bio cord filter media for
1 cubic meter frame is 100m.
There are usually two ways to fix the bio cord filter media. As
shown in Figure 1, the two ends of the bio cord filter media are
firstly bag-stitched, and then fixed with a fixed steel pipe
through the cloth bag. Figure 2, using the cable to bind the bio
cord to the frame directly.
In the method of Figure 1, the steel pipe passes through the
sewing bag and is fixed to the frame by a U-ring.
In the method of Figure 2, the bio cord filter media is fixed on
the frame outside the reaction tank, and then the frame is placed
in the reaction tank.
There are two ways to set the bio cord filter media in the
aeration tank. The first one is to install on one side and the
other side to aerate. The second is to set up and install on both
sides and aerate in the center. Space must be left above and below
the bio cord setting frame to maintain a good water flow state, and
a baffle (rectifier plate) can also be used to improve water flow
When the concentration of organic matter entering the biological
reaction tank is high, a backwashing device must be installed. The
excess sludge attached to the bio cord filter media is periodically
backwashed to maintain the efficient treatment activity of the
attached microorganisms on the bio cord.
There must be enough oxygen in the aeration tank. The amount of
aeration is determined by various conditions. If the amount of
aeration is calculated based on the organic matter content in the
wastewater, the amount of aeration per hour must be more than 3
times the volume of the aeration tank.
It is also necessary to use a diffusing tube, and pay attention
to a sufficient amount of air to achieve good processing
(10) After the above correct use method is achieved, the use of
bio cord filter media for wastewater treatment will certainly
achieve satisfactory treatment results.

The annular fiber bundle is formed by the inner core and the outer
fiber of the bio cord filter media.
The material of the bio cord filter media is composed of one or
more materials, and the specific surface area is adjusted by the
change of the material. The main chemical fiber materials used are:
the most hydrophilic chemical synthetic fiber-polypropylene fiber,
which can maintain stable structure of vinylon and nylon even if a
large number of microorganisms are attached, and the best elastic
recovery effect of polyvinylidene chloride. material.
The bio cord filter media has various outer diameters from 20mm
to 45mm, and the common standard size is 45mm. From the previous
experimental data, it can be seen that the 45mm diameter bio cord
filter media has the best microbial adhesion effect. As the
diameter of the bio cord filter media increases, the amount of
attached microorganisms also increases, but the microorganisms
attached per unit cross-sectional area tend to decrease.
The strength tension of the bio cord filter media is 74kg, which
can fully cope with the water flow impact in the reaction tank and
the weight of the attached sludge, and will not easily break.
