The environment, style and odor of sewage pool directly affect people's life and health. For the sake of people's physical and mental health and the harmonious development of society, many cities cover the sewage pool membrane to collect and manage the waste gas.
1. Corrosion resistance
The anti hanging membrane is covered and sealed because the membrane material used is the fluorocarbon fiber membrane (PVDF) with strong corrosion resistance, and the anti hanging membrane of sewage tank is covered with membrane cloth, and the steel structure directly suspends the membrane outside. The membrane cloth with strong corrosion resistance directly insulates the corrosive gas, which avoids the damage caused by the steel structure directly contacting the corrosive gas and greatly prolongs the service life of the steel structure Life;
2. Low cost
Because the span of primary sedimentation tank is generally large, the steel content is increased, so the cost of membrane structure construction is more advantageous;
3. Fast construction
Membrane structure construction is much faster than normal steel structure construction, and the construction site requirements are not high;
4. Easy to install
The surface of the membrane material used for covering and sealing the reverse lifting membrane of the sewage pool has a antifouling coating, and the surface is not easy to be contaminated with dirt and dust. It can be kept clean for a long time only by the washing of rainwater. The installation is very convenient, which reduces the occupation of the site, especially in the old pool closure reconstruction project, the membrane structure can be lifted as a whole without affecting the operation of the equipment inside the pool.
