Sewage treatment equipment plays a vital role in the sewage treatment process, they treat and purify sewage in a variety of ways to ensure that it meets the standards for safe discharge or reuse. The following is the main role of sewage treatment equipment in the sewage treatment process:

First, remove suspended solids

Sewage may contain suspended solid particles, suspended sediment and other impurities. Sewage treatment equipment removes these suspended substances through physical treatment processes, such as grilles, sedimentation tanks, filters, etc., to make the water clear. Grille filtration can remove large suspended and floating objects, such as plastic bags, branches, etc., to prevent them from clogging subsequent processing equipment; Precipitation is the use of gravity, so that the large particles in the sewage naturally sink to the bottom, forming sludge.

Second, degrade organic matter

Sewage contains a lot of organic matter, such as fat, protein, carbohydrates, etc. These organic matter is the main pollution source of sewage. Sewage treatment equipment through chemical treatment (such as ozone oxidation, chlorination, etc.) and biological treatment (such as activated sludge method, aerobic treatment, anaerobic treatment, etc.) and other processes, the organic matter is decomposed into lower harmless substances to further purify water quality. Biological treatment is the core link in the sewage treatment process, which uses the metabolic action of microorganisms to transform organic matter into stable inorganic matter.

Third, remove heavy metals

Sewage may contain heavy metal ions, such as lead, mercury, chromium, etc. These heavy metal ions have serious damage to water and ecological environment. Sewage treatment equipment can remove heavy metals through chemical methods (such as complex precipitation, ion exchange, etc.) to reduce environmental pollution.

Fourth, disinfection and sterilization

There may be a variety of microorganisms in sewage, such as bacteria, viruses, parasites, etc., which may pose a threat to human health. Sewage treatment equipment can kill these microorganisms through physical treatment (such as ultraviolet disinfection) and chemical disinfection (such as chlorination) to prevent the spread of diseases in the water body.

Fifth, the realization of water reuse

Sewage treatment equipment can also be further treated, and the treated water body can be used in agricultural irrigation, industrial production and other fields to achieve the reuse and reuse of water resources. This can not only save water resources, but also reduce the pollution of sewage discharge to the environment.

To sum up, sewage treatment equipment plays a vital role in the sewage treatment process, they treat and purify sewage in a variety of ways to ensure that it meets the standards for safe discharge or reuse. The application of these devices not only helps to protect the environment and maintain ecological balance, but also helps to improve resource utilization and human quality of life.
