Organic pollution

Organic pollution refers to pollutants composed of natural organic substances in the form of carbohydrates, proteins, amino acids, and fats, and certain other biodegradable synthetic organic substances. It can be divided into two categories: natural organic pollutants and synthetic organic pollutants. Organic pollution is very harmful to humans, but some measures can be taken to remove or reduce the harm.

Organic pollution sources: substances including phenols, aldehydes, sugars, polysaccharides, proteins and oils, etc., exist in large quantities in many industrial wastewaters. Organic pollution can be divided into two categories: natural organic pollutants and synthetic organic pollutants.

Organic pollution hazards: 1. The impact on the birth weight of children may reduce the birth weight of human babies. Stunting, skeletal development and metabolic disorders can all have an impact on human life. 2. It inhibits the nervous system, attention disorder, and immune system. 3. It is a hazard to the reproductive system. It also poses a potential threat to the human body’s endocrine system, leading to testicular cancer in men, decreased sperm count, abnormal reproductive function, imbalanced sex ratio of newborns, breast cancer in women, early puberty, etc., which not only harms individuals, but also their offspring Cause permanent effects. 4. It is to increase the incidence of cancer.

Organic pollution detection method: Indoor environmental pollutants mainly include formaldehyde, benzene, total volatile organic compounds, ammonia, radon, etc. The organic pollutants are mainly the first three. Common methods for determining formaldehyde include spectrophotometry and gas chromatography. The standard methods prescribed by the state are phenol reagent spectrophotometry, acetylacetone spectrophotometry, and gas chromatography. Commonly used gas chromatography for measuring benzene: Total Volatile Organic Compounds (TVOC), which are mainly volatilized from indoor building materials, paints, etc., can also be produced during smoking and cooking. Because of the large number of substances contained, they cannot be fully qualitative. Antoluene is calculated, mainly by gas chromatography. Because the content of organic pollutants in indoor air is low in the air, the enrichment absorption method should be used when collecting air samples.

Organic pollution solutions: 1. Place green plants in the room, such as Chlorophytum, Aloe, etc. These green plants have a certain absorption effect and can beautify the room. 2. Putting tea, pineapple, etc. to absorb harmful pollution, its cost is low, and it can achieve the function of deodorization. 3. Air purification device (the principle of adsorption purification). The purchase of machinery and equipment has a large power consumption and high cost. 4. Activated carbon (super adsorption capacity). Activated carbon can absorb harmful gases, can be used for a long time, and has low cost. 5. Chemical methods. There are many indoor air purification technologies, including photocatalytic technology, such as: titanium dioxide photocatalytic technology, which can degrade a variety of organic pollutants and inorganic pollutants such as sulfides and nitrogen oxides at room temperature and pressure, with rapid reaction and energy consumption Low, complete degradation, very suitable for indoor air purification.
