Micro-electrolysis catalytic oxidation technology has the following advantages:
1. Efficiently remove pollutants
Effective against a variety of pollutants
It can effectively remove organic pollutants in wastewater, such as phenols, benzene, halogenated hydrocarbons and other refractory organic matter, as well as nitrogen- and sulfur-containing heterocyclic compounds, and has a wide range of applications.
It also has a good removal effect on heavy metal ions such as chromium, mercury, lead, copper, etc., and can reduce them to forms with low toxicity or easy precipitation and separation.
High removal efficiency
This technology can achieve a high level of removal rate of organic pollutants, usually above 70% or even higher, and the removal rate for some specific pollutants can be close to 100%.
The removal rate of heavy metal ions is also considerable, which can significantly reduce the content of heavy metals in wastewater and meet the requirements of emission standards.
2. Mild reaction conditions
Normal temperature and pressure operation
Micro-electrolysis catalytic oxidation technology can be carried out at normal temperature and pressure, without the need for harsh conditions such as high temperature and high pressure. It has low equipment requirements, is easy to operate, and has relatively low operating costs.
This gives this technology great advantages in practical applications, especially for some small and medium-sized wastewater treatment projects, which can reduce investment and operating costs.
No need for additional medicines
In many cases, the micro-electrolysis catalytic oxidation process does not require the addition of a large amount of chemicals, reducing the cost of chemicals and the risk of secondary pollution.
The oxidative degradation of pollutants can be achieved only by relying on iron ions and other substances produced by micro-electrolysis and oxygen in the air, which is environmentally friendly.
3. Strong adaptability
Good adaptability to changes in water quality
This technology has strong adaptability to changes in wastewater quality and can maintain good treatment effects under different pH values, temperatures, salinity and other conditions.
For industrial wastewater with complex composition and large fluctuations, micro-electrolysis catalytic oxidation technology can operate stably and effectively remove pollutants.
Can treat high concentration wastewater
It can treat high-concentration organic wastewater and heavy metal wastewater. Micro-electrolysis catalytic oxidation technology has unique advantages for some wastewater with higher concentration that is difficult to treat with conventional methods.
It can be used as a pretreatment method to reduce the toxicity and load of wastewater and create conditions for subsequent in-depth treatment.
4. Simple equipment and small floor space
The equipment structure is simple
Micro-electrolysis catalytic oxidation equipment usually consists of a reactor, packing, aeration system, etc. The structure is relatively simple and easy to install and maintain.
Compared with some complex wastewater treatment processes, its equipment investment cost is low and the construction period is short.
Small footprint
Because the equipment has a compact structure and a small footprint, it is suitable for use in places with limited space, such as factory workshops, urban sewage treatment plants, etc.
Flexible layout can be carried out according to actual conditions to improve land utilization.
5. Less sludge is produced
Sludge reduction
The amount of sludge produced during the micro-electrolysis catalytic oxidation process is relatively small, which can greatly reduce the cost and difficulty of sludge treatment compared with traditional chemical precipitation methods.
This has important implications for reducing the overall cost and environmental impact of wastewater treatment.
Sludge properties are stable
The sludge produced is relatively stable in nature and is not prone to secondary pollution, making it easy for subsequent treatment and disposal. For example, it can be processed through dehydration, drying, etc., and then safely landfilled or recycled.
