The electrocoagulation method can be used alone or in combination
with other treatment methods, such as pretreatment method, which
can improve the biodegradability of wastewater; generally for
refractory organic wastewater, such as pharmaceutical, chemical,
fuel industry wastewater and contains refractory treatment The
toxic substances have a good treatment effect. Electro-flocculation
is mainly used to remove heavy metals, suspended solids and
emulsified organic matter in wastewater. It has been widely used in
petroleum and petrochemical industries, electroplating
industry,non-ferrous metal smelting industry and ship bottom sewage
treatment. The treatment effect of the process on pollutants is
shown in the following table:
Application of electroflocculation in treatment of high
concentration organic wastewater
When the high-concentration biochemical and non-biochemical organic
wastewater is treated by the traditional process, the traditional
process is used, the process is long, the operation cost is high,
the load is high, and the effect is not obvious; the
electroflocculation has been successfully used for such wastewater
treatment, Under the action of electric charge, biochemical and
non- biochemical organic matter directly breaks the molecular bond
and degrades COD. For example, high-concentration organic
wastewater in slaughtering and aquaculture, high-concentration
wastewater in food plants, alkane-containing wastewater in
petroleum industry, textile printing and dyeing wastewater, etc.
Application of electroflocculation in treatment of high ammonia
In the treatment of high ammonia nitrogen wastewater,
electroflocculation also has a good treatment effect, which has
been applied to the treatment of garbage leakage.
Application of electroflocculation in the treatment of
electroplating wastewater (including heavy metals)
Electro-flocculation in the treatment and reuse of electroplating
wastewater can overcome the problems that are difficult to solve by
chemical treatment. It can not only effectively remove heavy metal
ions in electroplating wastewater, but also reduce the salt content
in water, so that the treated water can be recycled and reused.
Process. Electroplating wastewater treated by electroflocculation
can achieve the following treatment effects: Cr<0.001, removal
rate up to 100%; Ni<0.005 removal rate up to 100%; Zn<0.062
removal rate up to 57%.
Application of electroflocculation in the treatment of fluorine-
In some developing countries, such as China, Egypt, India, etc.,
fluorosis is an endemic disease with a long-term comparison.
Therefore, the defluoridation problem of drinking water has become
a popular direction. The methods of removing fluorine include: lime
precipitation method, coagulation sedimentation method, adsorption
and ion exchange method, electrocoagulation method, electrodialysis
method, reverse osmosis method, etc.
Electrocoagulation is a more competitive method.
Application of electroflocculation in dye (high chroma) wastewater
Dye wastewater has the characteristics of high COD, high chroma,
high salt content, and difficult organic degradation of organic
matter. In the past, it has been generally treated by a combination
of physicochemical methods and biological methods. However, due to
the complicated drainage composition, the handling difficulty is
still large. With the development of electroflocculation
technology, electrocoagulation treatment of dye wastewater has the
advantages of small equipment, small land occupation, simple
operation management, high COD removal rate and good decolorization
Application of electroflocculation in wastewater treatment of
(including emulsified oil and heavy metals) Electroflocculation has
a unique effect in the treatment of oil latex, SS, organic matter.
Can be widely used in petrochemical, paint dyes, pigments and other
wastewater, car wash wastewater, oil field wastewater and other

Equipment operating costs
Power consumption: According to different water treatment
requirements, the electricity consumption per ton of water treated
Plate loss: According to different water treatment requirements,
the cost of plate consumption is 0.01-0.03 CN RMB / ton of water.
Electric flocculation operation cost: 0.06 - 0.78 CN RMB / ton of
water (electricity price is 0.5 CN RMB / kW)
Equipment operation instructions
The electric flocculation can be installed at the location near the
treatment site, and the power control cabinet should be placed in
the drying equipment room. If there are special explosion-proof
requirements, it needs to be explained in advance.
Method of operation
The equipment is a continuous automatic operation mode, and no
special care is required. The water inlet is provided with a flow
meter, and the flow rate can be controlled by the valve. The water
is pressurized by the pump into other processing systems, or
directly discharged, and the equipment discharge can be set to
manual or automatic control according to requirements.
- When the equipment is used, it needs to be turned on and then
turned on. If the equipment is not in use, the equipment cannot be
energized to avoid danger and equipment damage.
- Do not arbitrarily power off when the equipment is working through
- Do not touch the voltage output when powering up to avoid danger.
- Keep the heat sink well ventilated when the device is powered.
- The electrical parts must not be watered or wrapped in plastic
cloth or the like.
- The equipment must be shut down before servicing.
- If the subsequent process or equipment has been fouled, the treated
process or equipment should be drained once every 2 hours, no less
than 3 minutes each time; and the dirt should be cleaned regularly
to prevent the residue from clogging the equipment and causing an
- Do not rub hard when loading or unloading equipment.
