Description

Ecological water treatment device

Technical Field

The utility model relates to a sewage treatment field especially relates to an ecological water treatment's device.

Background

The water eutrophication refers to the phenomenon of water quality pollution caused by excessive content of nutrient salts such as N, P in the water. The essence of the method is that the species distribution of the water ecosystem is unbalanced and a single species grows excessively due to the unbalanced input and output of nutritive salt, so that the flow of substances and energy of the system is damaged, and the whole water ecosystem gradually goes to death.

In surface fresh water systems, phosphate is often the limiting factor for plant growth, while in seawater systems it is often ammonia nitrogen and nitrate that limits plant growth and overall production. Eutrophic substances, often nutrients of limited content in these water systems, for example, in normal freshwater systems the phosphorus content is usually limited, so that an increase in phosphate leads to overgrowth of the plants, whereas in seawater systems phosphorus is absent, while the nitrogen content is limited, so that the addition of nitrogen-containing pollutants eliminates this limiting factor and overgrowth of the plants occurs. Domestic sewage, wastewater from industries such as chemical fertilizers and foods, and farmland drainage contain a large amount of nitrogen, phosphorus and other inorganic salts. After the natural water body receives the wastewater, the nutrient substances in the water are increased, the autotrophic organisms are promoted to grow vigorously, particularly, the individual number of blue algae and red algae is increased rapidly, and other kinds of algae are reduced gradually. Algae in the water body mainly comprises diatom and green algae, the appearance of a large amount of blue algae is a sign of eutrophication, and the algae finally becomes mainly comprising the blue algae along with the development of the eutrophication. The algae can be rapidly propagated and the growth period is short. Algae and other plankton are decomposed by aerobic microorganisms after death, and dissolved oxygen in water is continuously consumed, or the algae and other plankton are decomposed by anaerobic microorganisms, and gases such as hydrogen sulfide are continuously generated, so that the water quality is deteriorated from two aspects, and a large amount of fishes and other aquatic organisms are killed. During the decay process of algae and other plankton residues, a large amount of nutrients such as nitrogen, phosphorus and the like are released into water for the utilization of new generation of algae and other organisms. Therefore, the eutrophic water body is difficult to self-purify and restore to a normal state even if the source of external nutrient substances is cut off.

In some slow-flow rivers, the water flow is slow, so that the oxygen in the water body is insufficient, and the ecological environment of the river water is further deteriorated.
