Sewage pipes are the main equipment for the discharge of urban domestic sewage and industrial wastewater, and they are also an important part of environmental protection work.Its role is to transport sewage or wastewater from the place where it is produced to the treatment facility or directly discharged into the water body, which plays a role in protecting the environment and maintaining hygiene.In daily life, we often come into contact with various pipelines, such as sewers, sewage pipes, water supply pipes, etc.The following will introduce the characteristics and applications of sewage pipes for everyone.

1. Characteristics of sewage pipes

1.Strong corrosion resistance

Sewage and wastewater contain a lot of acid, alkali, salt and other chemicals, and some also contain corrosive gases and liquids, so sewage pipes need to be corrosion-resistant.Commonly used sewage pipe materials are: plastic, cast iron, stainless steel, reinforced concrete, etc.Among them, the most widely used are plastic sewage pipes, which have the characteristics of excellent corrosion resistance, fire resistance and easy installation and maintenance.

2.Good compression resistance

Sewage pipes need to have sufficient compression resistance, mainly to withstand the impact of pressure fluctuations and pressure changes.Under normal circumstances, the internal pressure of the sewage pipeline does not exceed 0.3MPa, and the external pressure does not exceed 1.2MPa.

3.Good sealing

Sewage pipes need to have excellent sealing, no leakage, and prevent the spread of odors and bacteria.Its sealing performance directly affects the hygiene and pollution control of the urban environment.

4.Not easy to grow bacteria

There should be no dead corners, holes, bumps, etc. inside the sewage pipes to prevent bacterial reproduction, dirt deposition, and odor emission, so as to avoid environmental pollution and protect people's health and safety.

2. Application of sewage pipes

1.Urban domestic sewage treatment

Urban domestic sewage treatment is one of the main areas of sewage pipeline application.Urban domestic sewage is mostly organic matter and inorganic salts, and contains a lot of nutrients such as nitrogen and phosphorus. If it is directly discharged into the environment, it will not only easily cause eutrophication of water bodies, but also cause environmental pollution and health problems.Therefore, for urban sewage treatment, different treatment processes, such as biological treatment, chemical treatment, physical treatment, etc., need to be used to meet the discharge standards stipulated by the state.

2.Industrial wastewater treatment

Sewage pipes are also widely used in the treatment of industrial wastewater.Industrial wastewater is characterized by strong dependence, many types of pollutants and complex pollutants, which are difficult to deal with.Before industrial wastewater is discharged, pretreatment technology needs to be used to fully separate or remove heavy metals, organic matter, etc. through various treatment methods, so that the water quality can meet environmental protection discharge standards.

3.Agricultural irrigation

In agricultural production, sewage pipes are often used.A lot of water is often used in agricultural production. These water sources will eventually carry fertilizers, pesticides and other pollutants. If discharged at will, it will cause serious pollution to groundwater and soil. Therefore, in agriculture, modern drainage systems are also one of the essential environmental protection measures.

4.Public buildings

In the field of public buildings, sewage pipes also need to be fully used.A large amount of sewage is generated in public buildings, including schools, hospitals, hotels, etc.Sewage pipes need to discharge these sewage into the sewer network or treatment facilities.

In summary, sewage pipelines, as one of the important facilities for urban construction and environmental protection, are indispensable in our daily lives.As ordinary people, we should also do a good job of raising environmental awareness and protecting the environment around us.In the future development, the continuous improvement of technology will further improve the durability and efficiency of sewage pipelines, so that they can play a more important role in the cause of environmental protection.
