The reverse hanging film capping is to seal the odor to avoid affecting the surrounding environment and health, and the reverse hanging film capping is a widely used deodorization method.
The reverse hanging film capping is to seal the odor to avoid affecting the surrounding environment and health, and the reverse hanging film capping is a widely used deodorization method. With the help of air exchange between intake and outlet, the odorous gas is pumped into the deodorizer for deodorization. Generally covered in sludge thickening tank, sedimentation tank, aeration tank, digestion tank and other large-span pools.
Capping the reverse hanging membrane of the sewage tank only concentrated the odor in the reverse hanging membrane, and did not remove the odor. The odor in the normal operation of the sewage tank is constantly produced, only sealed treatment, without treatment, the odor concentration will be more and more large. Although the reverse hanging film has enough tightness, when the concentration reaches a certain limit, the odor will still overflow. This requires the odor to be transported through the pipeline to the deodorization equipment for treatment, in order to achieve the role of odor treatment.
The reverse hanging film is covered with a highly corrosion-resistant fluorine carbon fiber film to cover the exhaust gas, and the steel structure hangs the film outside. This not only gives play to the corrosion resistance of the fluorine carbon fiber film, but also fundamentally solves the corrosion problem caused by contact with corrosive gases of the steel structure. Therefore, the steel structure can be designed according to the corrosion resistance grade of the ordinary building steel structure, and the service life is 50 years, giving full play to the performance of the steel structure, and achieving the perfect combination of the structural skeleton and the covering material.
The usage rate of reverse hanging membrane covering in sewage tanks is increasing now. So, what risks can reverse hanging membrane covering in sewage tanks avoid? Let's take a closer look together.
With the progress of science and technology and the popularity of the concept of environmental protection, gas film building, as an innovative form of building, is gradually favored by people.So, when choosing a gas film building, what advantages should we pay attention to?
In recent years, ozone pollution has become a difficult problem affecting the improvement of atmospheric environment quality. As one of the main precursors of ozone formation, VOCs pollution control is an important topic for the "14th Five-Year Plan" PM2.5 and ozone collaborative control. Where is the difficulty of VOCs pollution control?
Inflatable membrane football stadium belongs to the indoor football field, the main structure adopts membrane structure design, the principle is the same as that of large balloons, due to the difference in internal and external pressure of the membrane structure, the tens of tons of membrane structure expands, and the surrounding is connected with the ground and anchored by steel cables and concrete ground, forming a tight air support structure, which can be built in the shortest time.
Shanghai Zhanji Fabric Structure Co., Ltd. is a professional membrane structure vendor who has an expert engineering design and construction team, and are at the leading position in this membrane field all over China.
