Common sense in the room to raise flowers
In the room, choosing the right flowers can greatly improve air quality and create a more pleasant living environment. Certain plants have remarkable abilities to absorb harmful substances. For example, plum trees can absorb mercury vapor, while pomegranate plants are effective at capturing lead particles from the air. Snapdragons, cannas, morning glories, and gladiolus can transform toxic sulfur dioxide into less harmful sulfate compounds through leaf oxidation. Narcissus, Mirabilis, chrysanthemums, and saxifrages can convert nitrogen oxides into proteins within their cells. Spider plants, aloe vera, and tiger orchids are known for their ability to absorb formaldehyde and other indoor pollutants, helping to reduce and prevent air pollution.
Some flowering plants naturally produce bactericidal substances. Jasmine, clove, honeysuckle, and morning glory release compounds that can kill certain airborne bacteria and help inhibit the spread of diseases such as diphtheria, tuberculosis, and typhoid fever.
Another interesting feature of flowers is their "complementary" behavior. Most plants perform photosynthesis during the day, absorbing carbon dioxide and releasing oxygen, while at night they take in oxygen and release carbon dioxide. However, cacti behave differently—they release carbon dioxide during the day and absorb it at night, releasing oxygen instead.
When placing flowers indoors, it's important to be mindful of how many you have. At night, most plants consume oxygen and release carbon dioxide, which can lower indoor oxygen levels. If too many plants are kept in a room, especially at night, this may cause discomfort such as chest tightness or disrupted sleep.
Additionally, some flowers emit strong or pungent scents. Orchids, roses, lilies, and night-scented flowers, for instance, can fill a room with intense fragrance. While pleasant, excessive fragrance can overstimulate the nervous system, leading to difficulty falling asleep, especially if the scent is present in the bedroom for long periods. Some plants, like Christmas poinsettias, emit gases that may not be ideal for prolonged exposure. Tulips and hydrangeas can also cause skin irritation if handled frequently due to their airborne particles.
Lastly, some flowers are actually toxic. The bulb of the daffodil contains lycorine, which can cause vomiting if ingested, particularly by children. Contact with the leaves or flowers can lead to redness and swelling on the skin, and if the juice gets into the eyes, it can cause serious eye damage.
By being aware of these characteristics, you can make smarter choices when selecting and arranging flowers in your home, ensuring a healthier and more comfortable living space.
COD controller, also known as COD transmitter, is an instrument used to monitor and control the level of chemical oxygen demand in water or wastewater.
COD (chemical oxygen demand) is an important indicator for measuring the content of organic pollutants in water. It reflects the amount of oxidant consumed by strong oxidants (such as potassium dichromate) to oxidize reducing substances (mainly organic matter) in water under certain conditions, usually expressed in milligrams per liter (mg/L).
The COD Sensor matched with the controller can quickly and accurately determine the COD value in the water sample through specific chemical reactions and detection technologies. It usually adopts advanced digital measurement technology and signal processing algorithms to ensure the accuracy and stability of the measurement results. It is also often equipped with an intelligent control system, which can automatically perform calibration, temperature compensation and other operations to improve the accuracy and reliability of the measurement.
In the fields of environmental protection, water treatment, scientific research, etc., COD controllers are widely used in water quality monitoring, wastewater treatment effect evaluation, pollution source investigation, etc. By using COD controllers, users can timely understand the content of organic pollutants in water bodies, so as to take corresponding treatment and protection measures to ensure that the water quality meets relevant standards and requirements.
In short, COD controllers are important water quality monitoring equipment and play a vital role in water quality protection and environmental management.
