The function of covering the sewage tank membrane is to seal harmful gases inside the sewage tank. Covering the sewage tank can effectively prevent the odor and harmful gases in the sewage tank from emitting into the air, affecting air quality and polluting the surrounding environment. It is an essential equipment in the sewage treatment process.
Add a membrane structure above the sewage tank to isolate the waste gas generated in the tank from the air. Add an air outlet on the outer surface of the protective cover and install a ventilation duct. The waste gas enters the waste gas pollution tower through the ventilation duct. To increase the collection of waste gas, a fiberglass fan is installed in front of the pollution tower, which sucks the waste gas into the pollution tower. The waste gas is sprayed in two stages inside the tower. If the waste gas is acidic, it is absorbed by alkali solution circulation. If the waste gas is alkaline, it is absorbed by acid solution circulation spray. The waste gas treatment efficiency is over 90%, and the discharge meets relevant national regulations.
The cleverness of the steel supported anti hanging UV film structure lies in the “anti hanging” feature. The seven color film uses fluorocarbon fiber film with strong corrosion resistance to cover the exhaust gas, while the steel structure suspends the film on the outside. This not only enhances the anti-corrosion function of UV film, but also fundamentally solves the corrosion problem of steel structures caused by contact with corrosive gases. Therefore, steel structures can be designed according to the anti-corrosion level of ordinary construction steel structures, with a service life of 50 years, which enhances the function of steel structures and completes the perfect combination of structural skeleton and covering materials.
