Description

Biological carrier sewage treatment equipment

Technical Field

The invention relates to sewage treatment equipment, in particular to biological carrier sewage treatment equipment.

Background

At present, the pollution of the river channel affects the physical and mental health of people and threatens the survival of aquatic organisms such as fish, so that the river channel needs to be treated as soon as possible and as best as possible.

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 the variety of other algae is 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.

For the treatment of water eutrophication, various countries and regions adopt different physical, chemical and biological methods to prevent, control and repair the eutrophication, and certain effect is achieved.

The main physical treatment methods at present comprise sediment dredging, water diversion flushing, mechanical aeration and the like, and mainly have the following problems:

1. on one hand, the engineering quantity is huge, and the operation cost is high;

2. on the other hand, sediment dredging is carried out on severely polluted rivers and lakes, so that the suspension and diffusion of sediments at the bottom layer are easily caused, the release of nitrogen and phosphorus nutrient salts in the sediments and metal ions adsorbed by the nitrogen and phosphorus nutrient salts is promoted, and the water environment is subjected to the risk of secondary pollution caused by the heavy metal ions released from the sediments and the nitrogen and phosphorus nutrient salts;

the chemical method comprises coagulant addition, algaecide addition and the like, and can achieve certain effects in a short time, but also has the following problems:

1. incomplete treatment and high cost;

2. secondary pollution is generated, and a new ecological problem is caused.
