What are the microorganisms in the water body in the inland wetlands?

Water microorganisms in inland wetlands generally have the following categories:

1 Bacteria: such as Bacillus, Escherichia coli, Proteus, cyanobacteria, etc.

2 Fungi: yeasts, filamentous fungi, etc.

3 Actinomycetes: Streptomyces, Nocardia, etc.

4 Zooplankton: paramecium, etc.

5 Algae.

Marine Wetlands Wetlands formed by the beach between the supratidal zone and the low tide line. The Ramsar Convention on Wetlands extends the wetland to a depth of 6 m below the low tide line. Inland wetlands are a general term for wetlands developed on land outside the coastal zone.

Constructed wetlands are wetlands formed by human factors. Such as paddy fields, reservoirs, canals, salt pans and fish ponds. Surface Flow Constructed Wetland The core technology of constructed wetland is undercurrent wetland.

Generally, it is composed of two levels of wetlands connected in series and treatment units in parallel. The wetland is filled with different media according to the different pollutants treated, and different kinds of purified plants are planted. The water is systematically purified through the physical, chemical and biological pathways of substrates, plants and microorganisms, and has significant removal efficiency of BOD, COD, TSS, TP, TN, algae, petroleum, etc.; In addition, the unique flow regime and structure of the process formed a good nitrification and denitrification functional zone, and the removal of TN, TP and petroleum is significantly better than that of other treatment methods.

It mainly includes the internal structure system, the active enzyomal medium system, the cultivation and matching system of plants, the water distribution and water collection system, the anti-clogging technology, and the winter operation technology. The forms of undercurrent synthetic wetlands are divided into vertical flow undercurrent constructed wetlands and horizontal flow undercurrent constructed wetlands. The influent water is purified by using the different flow characteristics in the wetland.

After underflow wetland purification, the river water can meet the surface water standard and then be discharged through the drainage system. Vertical flow underflow constructed wetland: In the vertical underflow system, the sewage flows longitudinally from the surface to the bottom of the bed, and the sewage passes through different patented medium layers in turn in the process of longitudinal flow to achieve the purpose of purification.

The vertical flow underflow wetland has a complete water distribution system and water collection system, which has the advantage of covering a smaller area than other forms of wetland, high treatment efficiency, the whole system can be completely built underground, and the ground can be built into green space and used with landscape planning. Horizontal flow underflow constructed wetland: It is another form of underflow wetland, in which sewage flows from one end of the inlet along the horizontal direction through sand, medium and plant roots, and flows to the end of the outlet in turn to achieve the purpose of purification.

Ditch-type constructed wetland: Ditch-type wetland bed includes a plant system, a media system, and a collection system. It mainly collects and treats non-point source pollution such as rainwater, and purifies rainwater and sewage through filtration, adsorption and biochemistry.

It is an effective means of water quality management and protection in small watersheds.

Common microorganisms in water are bacteria, fungi, bacteriophages, viruses, protozoa, algae, etc.

1. Bacteria. Bacteria (scientific name: bacteria) are one of the main groups of organisms and belong to the bacterial domain.

It is also the most abundant group of all organisms, with an estimated total of about 5,10,30 individuals. The shapes of bacteria are quite varied, mainly globular, rod-shaped, and spiral-shaped.

2. Fungi. A fungus, is a type of eukaryotic organism. The most common fungi are mushrooms, but fungi also include molds and yeasts.

More than 70,000 species of fungi have been discovered, estimated to be only a fraction of all that exist. Most fungi, which were originally classified into animals or plants, are now their own kingdom and are divided into four phyla.

3. Bacteriophages.

Phages are viruses that invade bacteria and are the genetic material that gives biological traits to the host bacteria. Bacteriophages must parasitize within living bacteria and have strict host specificity, which depends on the molecular structure and complementarity of phage adsorption organs and receptors on the surface of the recipient bacteria. Bacteriophages are the most prevalent and widespread group of viruses.

Bacteriophages can usually be found in places full of bacterial communities, such as soil and animal intestines.

4. Protozoa.

Protozoa are unicellular cells with specialized organelles that have all the functions necessary to sustain life and continue offspring, such as mobility, nutrition, respiration, excretion, and reproduction. Every protozoa is a complete organism.

5 Algae. Algae are a class of eukaryotes in the protist kingdom (some are also prokaryotes, such as the algae of the phylum Cyanobacteria). Mainly aquatic, non-vasculating, capable of photosynthesis.

They range in size from single-celled dinoflagellates as small as 1 micron long to large brown algae up to 60 meters long. Some leading experts continue to classify algae as plants or plant-like organisms, but algae have no true roots, stems, leaves, and no vascular bundles. This is the same as bryophytes.

Common aquatic.

Microorganisms: fungi, bacteria, protozoa, bacteriophages. Aquatic microorganisms in ecosystems.

They mainly play the role of decomposition. Without aquatic microorganisms, animal and plant residues, excrement, etc. cannot be recycled, and the substances will be locked in organic matter and cannot be used by producers, which will lead to the collapse of the entire ecosystem.

Bacteria, fungi, such as: actinomycetes, saprophytes, protozoa. They come in different carbohydrates.

Including sugar, starch, organic acids, cellulose, hemicellulose, etc. as energy sources.

Bacteria are important decomposers, they are widely distributed and can decompose organic matter, one gram of soil usually contains 40 million bacterial cells, and the bacteria on the earth form a biomass, this biomass is more than all existing plants and animals, bacteria are important in the circulation of nutrients, and the circulation of many nutrients is dependent on organisms.

Unlike bacteria, fungi are single-celled organisms.

Most saprophytic vegetative fungi increase the hyphae of divergent reticular systems. Bacterial proliferation is limited and eats exposed organic matter, and fungi can use their hyphae to penetrate larger organic matter.

Water in nature can be divided into groundwater and surface water, and in addition to deep underground water, there are various microorganisms present in various surface waters such as lakes, rivers, oceans, etc. However, they contain different types of microorganisms, in number and in distribution.

Some of them are "autochthonous", such as sulfur bacteria, nitrifying bacteria, iron bacteria, photosynthetic bacteria, etc. in autotrophic bacteria. Heterotrophic bacteria include Pseudomonas, actinomycetes, fungi, protozoa and algae. Among the aquatic bacteria, gram-negative bacilli are the most common (95), positive bacteria account for 4, and cocci account for only 1.

Other aquatic bacteria are foreign and come from soil, air, garbage, factory waste, or municipal sewer sewage. The microorganisms from the first two are generally saprophytic, whereas among the microorganisms from the sewers,

Microorganisms in activated sludge.

Activated sludge is a general term for the microbial community and the organic and inorganic substances they adsorb. The microbial community mainly includes bacteria, protozoa, and algae, among others. Among them, bacteria and protozoa are the two main categories.

a) Bacteria. Bacteria are single-celled organisms like cocci, bacilli, and spirochetes, among others. They have many types, large quantities and small volumes in activated sludge, and have strong ability to adsorb and decompose organic matter, and play a key role in sewage treatment.

In the early stage of activated sludge culture, a large number of bacteria are free in the sewage, but with the gradual formation of sludge, they gradually gather into larger groups, such as mycelium, filamentous bacteria, etc.

Colloids. The colloidal pellet is a fine particle composed of bacteria and the colloidal substances secreted by it, which is the main body of activated sludge, and the adsorption performance, oxidative decomposition ability and coagulation and sedimentation properties of the sludge are all related to the mycelium. The colloidal group is spherical, branched, mushroom-shaped, and vertical.

2.Jersey bacteria.

This bacterium has a large demand for carbon nutrients, and often has a large number of carbohydrates, which causes them to multiply too quickly and cause sludge to expand, so it has a strong ability to decompose organic matter.

White sulfur bacteria can decompose sulfur-containing compounds; Thiophafilament bacteria are a common filamentous bacterium that can loosen the sludge and even cause the sludge to swell when it multiplies.

It is recommended that the landlord adopt it as the answer.

Bacillus, actinomycetes, fungi, algae.

According to the different living environments, organisms can be divided into terrestrial organisms and aquatic organisms.

The distinction is based on the living environment.

Other introductions. Terrestrial organisms generally refer to organisms that live on land. They usually possess the following characteristics:

1. It has a structure to prevent water dispersion, such as reptiles have scales or nails, and insects have exoskeletons; 2. It has organs that support the body and movement, and has a variety of movement methods, such as: crawling, walking, jumping, running, etc., in order to forage for food and avoid predators; 3. Have respiratory organs located inside the body that can breathe in the air, such as lungs and trachea. (The exception is earthworms, which breathe against the body wall); 4. It has well-developed sensory organs and nervous system, and can respond to the changing environment in a timely manner.

The terrestrial environment is much more complex than the aquatic environment.

Aquatic life. Aquatic life is a general term for organisms that live in various types of water bodies. There is a wide variety of aquatic life, with various microorganisms, algae, as well as aquatic higher plants, various invertebrates and vertebrates.

The lifestyle is also diverse, including floating, squakling, swimming, sessile and cave-dwelling.
