Three Manifestations of the Anti-hanging Film on the Sewage Tank

The problem of waste gas pollution from sewage ponds has become one of the important issues affecting ecological and environmental protection, especially for enterprises in some industrial production areas. Unreasonable discharge of sewage and other issues have caused serious pollution to the environment. Therefore, the sewage pond must be rehabilitated. Cover treatment to prevent unreasonable discharge of waste water and waste gas from polluting the environment.

According to different structures, the sewage tank can be divided into steel frame anti-hanging film, tension anti-hanging film and inflatable anti-hanging film.

1. The steel frame anti-hanging membrane is to use the steel structure as the support frame and use the principle of the membrane material to hang the steel structure against the outside of the membrane material to protect the steel structure from corrosion by the exhaust gas in the pool and prolong the service life of the steel structure .

2. The tensioned anti-hanging membrane can be provided with support points such as masts, and anchor points can be set around it to form a stable system through tensioning.

3. The inflatable anti-hanging membrane structure should have a closed inflatable space, and an inflatable device that maintains internal pressure should be installed. The internal pressure is used to maintain the tension of the membrane material and form a curved surface as required by the design. Air-bearing, air-ribbed and air pillows can be used formula.

The membrane material used for the anti-hanging membrane of the sewage tank is the latest environmentally friendly membrane material. The outer coating of the membrane material has strong physical and chemical resistance, and is still not subject to high heat, severe cold, strong acid and alkali, and strong corrosion.
