Biofilm method:
A method of treating sewage or waste gas by using a film-like biome fixed on
the surface of inert material. The biological filter method, biological
contact oxidation method and biological turntable method all belong to this
method.
Distillation Technology
(1) Biological filter A bioreactor used to treat sewage, which is filled with
inert filter material, and biological communities grow on the surface of the
material to treat pollutants. Advantages: 1) The treatment effect of the
biological filter is very good, and it can meet the strictest environmental
protection requirements in all seasons. 2) No secondary pollution. 3)
Microorganisms can grow on the organic matter in the filler without adding
additional nutrients. Therefore, it is quick to start after shutdown, and can
quickly restore the best use effect. 4) The biological filter has a large buffer
capacity, which can automatically adjust the peak concentration so that the
microorganisms always work normally and have a strong resistance to impact
loads. 5) The operation adopts automatic control, which is very stable and does
not require manual operation. There are few vulnerable parts, maintenance and
management are very simple, and unmanned management can be basically achieved.
Workers only need to inspect whether there is a machine failure. 6) The body of
the biofilter is assembled, which is convenient for transportation and
installation; when increasing the processing capacity, only components need to
be added, which is easy to implement; and it is also convenient for separate
treatment under the conditions of air source dispersion. 7) The energy
consumption of this type of filtration type biological filter is very low, and
the pressure loss of the filter after only six months of operation is only about
500Pa.
(2) Biological turntable An aerobic bioreactor for sewage treatment. It is
composed of a water tank and a set of discs. The lower part of the disc is
submerged in water, the upper part of the disc is exposed to the air, and there
are biological communities growing on the surface. The rotating turntable
repeats Contact with sewage and oxygen in the air to purify the sewage.
Advantages: 1) Small footprint, compact structure 2) Low energy consumption,
high treatment efficiency 3) Convenient management and easy operation Especially
suitable for sewage treatment of small and medium-sized livestock and poultry
processing plants
(3) The structure of biological contact oxidation tank includes tank body,
filler, water distribution device and aeration device. The working principle is:
setting filler in the aeration tank and using it as the carrier of biofilm.
After being oxygenated, the wastewater to be treated flows through the filler at
a certain flow rate, contacts the biofilm, and the biofilm and suspended
activated sludge work together to purify the wastewater. Advantages: 1) High
volume load, strong impact load resistance 2) The advantages of membrane method,
less residual sludge 3) The advantages of activated sludge method, supplemented
by mechanical equipment for oxygen supply, high biological activity, short mud
age 4) Can decompose other biological treatment difficult to decompose
substances 5) Easy to manage, eliminate the disadvantages of sludge floating and
expansion
