Geomembrane application case: Sewage treatment plant case application
Geomembrane treatment of sewage ponds is a technology widely used in environmental protection projects. Its basic principle is to use the permeability and filterability of geomembrane to separate the harmful substances in sewage, so as to achieve the purpose of purifying water quality. Here we will introduce the basic principle, construction process and advantages of geomembrane treatment of sewage ponds in detail.
Basic Principles
Geomembrane is a kind of thin film made of polymer material, which has excellent permeability and filterability. In sewage ponds, geomembrane is used as a medium to separate harmful substances from sewage. Specifically, geomembranes allow water molecules to pass through, while preventing soil particles, suspended solids, and harmful substances from passing through. In this way, the harmful substances in the sewage are trapped by the geomembrane, and the water flows out through the geomembrane.
Application process
1.Preparatory work
Before construction, it is necessary to carry out site investigation and cleaning work to ensure that the construction area is clean and smooth. At the same time, prepare the required geomembrane materials and construction equipment.
2. Lay geomembrane
According to the design requirements, the geomembrane is laid on the bottom of the sewage pond. During the laying process, it should be ensured that the geomembrane is flat, without wrinkles and bubbles, and excessive stretching or distortion should be avoided.
3.Fixing the geomembrane
In order to ensure that the geomembrane will not shift or slip, it is necessary to fix it around the anchor rod, batten or steel frame. When fixing, attention should be paid to moderate strength to avoid damage to geomembrane.
4. Testing and debugging
After laying and fixing, it is necessary to test and debug to ensure that the geomembrane can operate normally. It includes pressure test, permeability test and filtration effect evaluation of geomembrane.
5. Maintenance and maintenance
During operation, it is necessary to carry out regular maintenance and maintenance of the geomembrane, including cleaning and replacing the damaged geomembrane, etc., to maintain its good filtration effect and service life.
1.High efficiency: geomembrane has high filtration performance, which can effectively intercept harmful substances in sewage and achieve the purpose of purifying water quality.
2.Simple construction: the geomembrane laying and installation process is relatively simple, and does not require complex mechanical equipment and professional skills, so the construction period can be greatly shortened.
3.Strong adaptability: geomembrane can be designed into various shapes and sizes according to actual needs to meet the needs of different specifications and types of sewage ponds. At the same time, its installation and use process does not require special maintenance and management, with strong adaptability.
4.Strong durability: geomembrane is made of polymer material, has good corrosion resistance and durability, can maintain its original performance and shape for a long time, to ensure the stability and reliability of sewage treatment.
5.Economic benefits: Compared with the traditional sewage treatment process, geomembrane treatment has the advantages of low cost and high efficiency. Although the initial investment of geomembrane is relatively high, its long-term operation cost is low, and it does not require a lot of manpower and material input, so it has a high cost performance.
Geomembrane treatment is an efficient, simple, adaptable, durable and economical sewage treatment technology, which has been widely used in environmental protection projects.
