What are the reasons for industrial sewage treatment and how to deal with odor?

Industrial sewage treatment can clean human food, which is conducive to human long-term development and environmental protection. The commonly used methods include catalytic activated carbon method, combustion method, ozone oxidation method, etc. the following describes in detail the "causes of industrial sewage treatment and odor treatment".

1、 Causes of industrial sewage treatment

1. The decomposition of organic matter in sewage by microorganisms consumes a lot of oxygen, resulting in the death of organisms in water. Sewage treatment protects aquatic organisms, so as to protect the ecological balance;

2. Heavy metals in sewage enter the human table through the food chain and endanger human health. Sewage treatment cleans human food and is conducive to human long-term development.

3. The odor generated by sewage pollutes the atmosphere and endangers the environment. Sewage treatment is conducive to environmental protection.

2、 How does industrial sewage treatment equipment deal with odor

1. Catalytic activated carbon process

The traditional activated carbon adsorption method has the disadvantages of high regeneration cost of activated carbon and troublesome operation of replacing activated carbon.

2. Combustion method

Combustion methods include direct combustion method and coal contact combustion method. According to the characteristics of odor, when the temperature reaches 648 ℃ and the contact time is more than 0.3s, the odor will burn directly to achieve the purpose of deodorization.

3. Ozone oxidation

Ozone oxidation method uses ozone strong oxidant to oxidize the chemical components in the odor to achieve the purpose of deodorization, such as ozone generator. Ozone oxidation method can be divided into gas phase and liquid phase. Due to the slow chemical reaction of ozone, most odorous substances are removed by liquid medicine cleaning method, and then ozone oxidation is carried out.

4. Water cleaning and chemical deodorization

Water cleaning is to use the characteristics that some substances in the odor can be dissolved in water to make ammonia and hydrogen sulfide in the odor contact and dissolve with water to achieve the purpose of deodorization. Ozone generator.

5. Biological deodorization

Biological deodorization method is to transform odorous substances through microbial physiological metabolism to achieve the purpose of deodorization. At present, the methods of biological treatment of odor in sewage treatment plants at home and abroad mainly include soil treatment method and biological filter method, and the deodorization effect is good.

6. Spraying technology of plant extract

Spray the plant extract with atomization equipment to form small fog particles with large specific surface area, adsorb odor molecules in the air for reaction or catalyze the reaction with oxygen in the air to produce tasteless products without secondary pollution.
