What is Rich Oxidation Rich Oxidation Eutrophication?

Eutrophication refers to the process of increasing the growth and reproduction of algae and other aquatic organisms due to the discharge of a large amount of nitrogen, phosphorus, potassium and other elements into the surface water body with a slow flow rate and long renewal cycle, so that the rate of organic matter production far exceeds the consumption rate, and the organic matter in the water body accumulates, destroying the aquatic ecological balance.

Eutrophication refers to the large amount of nutrients such as nitrogen and phosphorus required by organisms entering lakes and rivers under the influence of human activities.

Slow water bodies such as mouths and bays cause the rapid growth of algae and other plankton, the decrease of dissolved oxygen in the water body, the deterioration of water quality, and the death of a large number of fish and other organisms. Under natural conditions, lakes also transition from eutrophication to eutrophication, albeit very slowly. However, eutrophication of water bodies caused by the artificial discharge of industrial wastewater and domestic sewage containing nutrients can occur in a short period of time.

When eutrophication occurs in a water body, planktonic algae bloom in large numbers, forming a bloom (a natural ecological phenomenon in which algae bloom in freshwater bodies). Due to the different colors of the dominant planktonic algae, the water surface tends to appear blue, red, brown, milky white, etc. This phenomenon in the ocean is called red tide or red tide.

Rich oxidation refers to the valency of oxygen in the compound is -1, and the general reduction of oxygen is -2 valence, but in some cases the oxygen is too sufficient, which can be understood as the -2 valence oxygen is oxidized by oxygen atoms, thus showing -1 valence, such as hydrogen peroxide H2O2 and sodium peroxide Na2O2

For example, a large amount of factory waste and domestic waste is discharged into the water, and a large amount of nutrient-rich substances such as nitrogen and phosphorus are overgrown by algae, which consumes oxygen in the river, kills a large number of fish and other organisms, and forms the so-called red tide.

The August of Jesus is eutrophication, not oxygenation.

It is eutrophication, which refers to the excessive nitrogen, phosphorus and potassium in the water (these are necessary for plant growth), so it will cause the rapid growth of algae in the water, after the death of algae, the corpse will decay under the action of bacteria, this process will consume oxygen, and bacteria will also consume oxygen, which will eventually lead to a lack of oxygen in the water, resulting in a large number of fish and shrimp death.

It depends on the use of**.

If water quality is oxidized, it is eutrophication.

However, in mineralogy, some minerals are called oxide-rich ores, which means minerals with a high oxygen content. For example, zinc oxide-rich ore, iron oxide-rich ore, etc.

Oxygen is a non-polar molecule with very low solubility in water, and the presence of ions does not enrich the water with oxidation.

Red tides are discoloration of seawater caused by abnormal proliferation or aggregation of planktonic algae, protozoa, or bacteria in seawater. Red tide is a kind of disaster, which has appeared in history for a long time, but it has not become more serious until now.

Red tide is a historical name, but in fact, red tide is not always red, it can take on different colors depending on the species and number of organisms that cause it. For example, the red tide formed by noctilucent algae and medium stingworm is red, the red tide of eugleniflagellate is mostly dark brown and reddish-brown, the red tide of Ceratocophyllum is generally brownish-yellow, the red tide of green mountain algae is green, and the red tide of some diatoms is generally brownish-yellow. In 1937, the red tide of floating sciulator and rhomboids in Xigang, Xiamen, caused the water to be yellowish brown and slightly greenish.

Therefore, red tide is actually a general term for various color tides.

Red tides are divided into open sea type and inner bay type, exotic type and primary type, and monophasic, biphasic and multiphasic type depending on the species of organisms present.

Eutrophication refers to the large amount of nutrients such as nitrogen and phosphorus required by living organisms entering slow flowing water bodies such as lakes, estuaries, and bays, causing algae.

and other phenomena such as the rapid reproduction of plankton, the decline of dissolved oxygen in the water body, and the mass death of fish and other organisms.

A large number of dead aquatic organisms are deposited on the bottom of the lake, where they are decomposed by microorganisms and consume large amounts of dissolved oxygen.

The dissolved oxygen content of the water body is drastically reduced, and the water quality deteriorates, which affects the survival of fish and greatly accelerates the eutrophication process of the water body. When eutrophication occurs in the water body, due to the mass proliferation of plankton, the water body often appears blue, red, brown, milky white, etc., this phenomenon is called bloom (water splash) in rivers and lakes, and red tide in the sea.

In the waters where red tides occur, some plankton multiply explosively, turning the water red, hence the name "red tide". These algae have a foul smell, are poisonous, and cannot be eaten by fish. Algae shade the sunlight and allow benthic plants to photosynthesize.

It is hindered and dies, and after decay, it releases nutrients such as nitrogen and phosphorus, which are then used by algae. This leads to a vicious cycle, with algae blooming, water quality deteriorating and fishy, and lack of oxygen in the water, causing fish to suffocate and die.

Eutrophication is a phenomenon in which the amount of dissolved oxygen in water decreases and the water quality deteriorates due to the bloom of plants, especially algae.

Eutrophication refers to the phenomenon of water pollution caused by excessive nutrient content such as N and P in water bodies. Its essence is that the input and output of nutrients are out of balance, which leads to the imbalance of species distribution in the aquatic ecosystem, and the crazy growth of a single species, which destroys the flow of matter and energy in the system, and gradually extinguishes the entire aquatic ecosystem.

Excess nitrogen, phosphorus and other nutrients in the water body mainly come from untreated or incompletely treated industrial wastewater and domestic sewage, organic waste and livestock and poultry manure, as well as agricultural fertilizers, the largest of which is a large amount of chemical fertilizers applied on farmland.

Water eutrophication: Water eutrophication refers to the phenomenon that after nitrogen, phosphorus and other nutrients are discharged into rivers and lakes, the nitrogen and phosphorus content in the water increases, and the water quality tends to eutrophication, resulting in a large number of algae and aquatic weeds, turbid water quality, hypoxia in the water body, and the death of fish and other aquatic organisms.

Typical representatives: .Red tide (seawater) and bloom (freshwater) are typical representatives of eutrophication in water bodies.

It is too much nitrogen, phosphorus and potassium in the water that promote the growth of plants, which leads to the growth of plants in the water and the suffocation of organisms in the water.

Phosphorus and nitrogen accumulate in water bodies, causing algae to grow and damage the environment.

It refers to the phenomenon of water pollution caused by excessive content of plant nutrients such as nitrogen and phosphorus.

From the perspective of ecological water treatment, eutrophication refers to the phenomenon of water pollution caused by excessive nutrient content such as N and P in the water body. Its essence is that the input and output of nutrients are out of balance, which leads to the imbalance of species distribution in the aquatic ecosystem, the crazy growth of a single species, the destruction of the flow of matter and energy in the system, and the degradation and even extinction of the entire aquatic ecosystem.

When eutrophication occurs in a water body, under certain natural conditions, planktonic algae may bloom, forming malignant ecological events such as blooms (algal blooms), red tides or green tides.

Evaluation of lake eutrophication:

It is to make an accurate judgment on the trophic status of the lake through a series of indicators related to the trophic status of the lake and the interrelationship between the indicators. At present, the basic method of lake eutrophication evaluation in China mainly adopts the comprehensive trophic state index (TLI) and the comprehensive trophic state index (TLI) ( ), that is, the index of chlorophyll a (CHLA), total phosphorus (TP), total nitrogen (TN), transparency (SD) and permanganate index (CODMN) is comprehensively evaluated according to a certain calculation method.

It is a water deterioration caused by high concentrations of nitrogen, phosphorus and potassium.

Eutrophication is eutrophication.

It's overnutrition! Too much.
