With the continuous acceleration of urbanization, the problem of environmental pollution is becoming more and more serious, and the problem of water pollution has attracted much attention. In order to solve this problem, sewage treatment equipment came into being. This paper will focus on the types, characteristics and applications of sewage treatment and environmental protection equipment, in order to provide useful reference for technicians and enterprise managers in related fields.
1. Types and characteristics of sewage treatment and environmental protection equipment.
Sewage treatment and environmental protection equipment mainly includes three categories: physical treatment equipment, chemical treatment equipment and biological treatment equipment.
1.Physical processing equipment.
Physical treatment equipment mainly removes suspended solids and some dissolved impurities in water through physical means, such as precipitation, filtration, separation, etc. Common physical treatment equipment includes grilles, sedimentation tanks, filters, etc. These devices are simple in structure and easy to operate, and are suitable for sewage treatment with small water quality fluctuations and low pollutant concentrations.
2.Chemical processing equipment.
Chemical treatment equipment mainly removes dissolved harmful substances in water through chemical reactions, such as oxidation, reduction, neutralization, etc. Common chemical treatment equipment includes dosing devices, electrolyzers, etc. The treatment effect of these equipment is stable, and it is suitable for sewage treatment with high pollutant concentration and difficult biochemical treatment.
3.Biological treatment equipment.
Biological treatment equipment mainly degrades organic pollutants in water through the metabolism of microorganisms. Common biological treatment equipment includes activated sludge device, biofilm device, etc. These equipment has the advantages of good treatment effect, energy saving and environmental protection, and is suitable for the treatment of various organic pollutants.

Second, the application of sewage treatment and environmental protection equipment.
With the continuous progress of technology, sewage treatment and environmental protection equipment has been widely used in urban sewage treatment, industrial wastewater treatment and other fields.
1.Municipal sewage treatment.
Urban sewage treatment is an important application field of sewage treatment and environmental protection equipment. Through the construction of sewage treatment plants, the use of physical, chemical and biological treatment methods, can effectively remove all kinds of pollutants in urban sewage, meet the national discharge standards, and protect water resources and ecological environment.
2.Industrial wastewater treatment.
The composition of industrial wastewater is complex, the pollutant concentration is high, and the treatment is difficult. According to the characteristics of wastewater in different industries, the selection of appropriate sewage treatment and environmental protection equipment can effectively reduce the content of harmful substances in wastewater and realize the recycling and discharge of wastewater.
3. Conclusions and prospects.
Sewage treatment and environmental protection equipment is an important means to solve the problem of water pollution. For different types of water pollution, the selection of appropriate sewage treatment equipment can effectively improve water quality and protect the ecological environment. In the future, with the continuous progress of technology and the continuous expansion of application fields, sewage treatment and environmental protection equipment will develop in the direction of more efficient, energy-saving and environmental protection, and create a better living environment for human beings.
