[ Focus on Chemical Machinery and Equipment Network ] It is like a red ghost, disturbing the ecological civilization of the sea all day long, and it often reappears after the treatment, which plagues countless farmers and scientists in the world
.
——It is the red tide
.
Chemical machinery and equipment network hotspots pay attention to chemical machinery and equipment.
——It is the red tide
.
This is a kind of seemingly inconspicuous marine microalgae.
It is affected by the increasing extent and depth of ocean utilization by human activities to form red tides.
As the outbreak time becomes longer and longer, the frequency becomes higher and higher.
Red tides give China every year.
The economic loss caused reached 30 billion yuan, and even threatened the safety of the cold source of coastal nuclear power.
It is also listed as one of the three major offshore environmental problems in the world

Farmland sensor detects the nitrogen content of fertilizer to prevent red tide
Farmland sensor detects the nitrogen content of fertilizer to prevent red tide sensor
The red tides formed by the eutrophication of water bodies are harmful to aquatic life, wild animals and even humans.
The main reason is that a large amount of nitrogen, phosphorus and potassium-containing wastewater is discharged into the water body, causing the algae to grow explosively
.
Over-fertilized farmland is also a major source of red tides.
In order to monitor and prevent the occurrence of red tides, professionals have invented a sensor that can be buried under the farmland to prevent red tides from being over-fertilized

.
Since farmers cannot quickly know that the farmland has received enough fertilizer when applying nitrogenous fertilizers, it usually leads to over-fertilization
.
The newly developed sensor that can be buried under the farmland can monitor the nitrogen content of the farmland after fertilization to ensure that it will not be excessive
.
These low-cost devices can be laid out using only ink-jet printed and laser-etched graphite circuits
.
Farmers can read the data of its built-in hub through the device, and accurately detect whether the nutrients needed in the farmland are sufficient
.
Not only can it prevent red tides, but it can also help farmers reduce fertilizer costs

Water quality monitoring to avoid water eutrophication
Water quality monitoring to avoid water eutrophication It is understood that red tides are extremely harmful to water bodies
.
A large number of studies have shown that among the more than 260 species of marine planktonic algae known to cause red tides, as many as 70 species can produce toxins
.
These toxins will not only cause the death of a large number of fish, shrimp, crabs, and shellfish, but also destroy aquatic resources, and in severe cases, they will also form sediments and affect the construction of harbours
.
To avoid the occurrence of red tides, it is necessary to prevent eutrophication in the water body and control the content of nutrients such as nitrogen and phosphorus in the water within a certain range
.
Therefore, to avoid the occurrence of red tides, water quality monitoring and analysis are indispensable

Therefore, to avoid the occurrence of red tides, water quality monitoring and analysis are indispensable
.
Water quality monitoring using various detector and devices, comprehensive, water periodically to various pollutants of the type, concentration, and trends were determined and analyzed further to assess the situation of water of the process
.
The scope and content of water quality monitoring are very extensive, and the detection techniques and instruments involved are also diverse
.
At present, water quality monitoring of physical and chemical techniques mainly based detection, electrochemical common methods, atomic absorption spectrophotometry, ion chromatography, gas chromatography and the like
.
If we want to detect the nutritional level of water bodies, we can use UV-visible spectrophotometers, total nitrogen analyzers, total phosphorus analyzers, suspended solids analyzers, and water toxicity analyzers and other instruments

Summarize
Summarize Red algae can cause many hazards.
To prevent the occurrence of red algae, in addition to using water quality analysis instruments to accurately monitor the water environment and timely understanding of water quality, the more important thing is our protection of the ecological environment.
Whether it is water quality, soil or atmosphere, it is closely related to our health.
Only by maintaining the natural environment in which we live can our own safety and health be guaranteed
