In the sewage treatment plant, the tanks are mainly square tanks and round tanks. Generally, the square tank adopts an arched sealing scheme. So how should the anti-hanging membrane sealing scheme be selected as a circular tank?
Generally speaking, the circular sewage tank is sealed with anti-hanging membrane. First, the situation of the sewage tank will be asked to roughly determine the sealing scheme of the tank body.
The centrally driven sewage tank generally chooses a fixed anti-hanging membrane sealing scheme. The sewage part uses a steel structure as a supporting structure, and the membrane material is covered on it. The membrane material can be used to isolate the bridge frame to avoid corrosion of the bridge frame.
For the sewage tank with peripheral transmission, the follow-up anti-hanging film sealing scheme can be selected, that is, the anti-hanging film rotates with the mud scraper. Of course, a fixed sealing scheme can also be used, but sealing the entire bridge frame will affect the service life of the scraper.
