The service life of sewage treatment equipment is a complex and changeable issue, which is affected by many factors, including equipment type, quality, operating environment, maintenance and sewage treatment process. The following is a detailed analysis of the service life of sewage treatment equipment:

First, the type of equipment

1. Mechanical equipment: This type of equipment is relatively simple, and the service life is usually about 5 years. The wear and damage of mechanical parts are the main factors affecting their life.

2. Biological equipment: Biological equipment is relatively complex and generally requires maintenance for more than 10 years. The stability and activity of the biofilm have an important impact on the performance of the equipment, and proper maintenance can extend the service life.

3. Physical and chemical equipment: This type of equipment is more complex and has a service life of more than 20 years. The stability and reaction efficiency of the material during physicochemical treatment are the key to determine its life.

4. Integrated sewage treatment equipment: high-quality integrated sewage treatment equipment, after scientific design and fine manufacturing, can be used under normal operating conditions for many years, or even more than ten years.

Second, equipment quality

The quality of the equipment is a key factor in determining its service life. High quality materials, precision manufacturing processes and strict quality control all provide a strong guarantee for the stability and durability of the equipment.

Third, the operating environment

1. Climatic conditions: the installation location and climatic conditions of the equipment will directly or indirectly affect the service life of the equipment. For example, extreme weather conditions may accelerate the aging and damage of equipment.

2. Water quality: the composition and concentration of sewage also have a great impact on the equipment. High concentrations of sewage may aggravate corrosion and wear of equipment.

Fourth, maintenance

Regular cleaning, inspection and maintenance of the equipment can detect and solve problems in time, thus extending the service life of the equipment. On the contrary, if the equipment is not effectively maintained for a long time, its performance may gradually decline, and eventually lead to early scrapping of the equipment.

Fifth, other influencing factors

1. Equipment upgrade: With the continuous development of science and technology, a new generation of sewage treatment equipment is constantly being launched. For some aging sewage treatment equipment, the necessary equipment upgrades and updates can extend their service life, while improving the operating efficiency and production capacity of the equipment.

2. Operation mode: The correct operation mode can avoid unnecessary loss and failure, thus extending the service life of the equipment.

Sixth, specific cases and parameters

The first trouble-free operation time of the pump unit used in some sewage treatment equipment should not be less than 10,000 hours, and the service life should not be less than 10 years.

The cumulative time of trouble-free operation of the submersible push mixer should not be less than 2 years, and the service life should not be less than 10 years.

The first trouble-free operation time of the blower should not be less than 10,000 hours, and the service life should not be less than 10 years.

The service life of the biochemical tank filler varies according to the material, but generally should not be less than 5 years.

To sum up, the service life of sewage treatment equipment is a comprehensive problem, which needs to consider many aspects of equipment type, quality, operating environment, maintenance and sewage treatment process. In practical applications, the appropriate equipment should be selected according to the specific situation, and the maintenance of the equipment should be strengthened to extend the service life of the equipment and improve the efficiency of sewage treatment.
