People have paid more attention to environmental protection in their lives, and Shanghai, where the editor of a membrane structure, has also implemented a garbage separation policy. Can the membrane structure be combined with the cover of the sewage tank? And how can we better solve those existing sewage pond pollution? There are many questions, and we will answer them one by one.
Membrane structure sewage tank cover contains a lot of content. Commonly, there is a steel-supported anti-suspended fluorocarbon fiber membrane sewage tank waste (odor) gas collection device, which is a type of anti-suspended sewage tank cover. That is, the steel is supported on the outside and the membrane is on the inside and fixed by tension; the main materials are ordinary carbon steel and high-strength membrane (PVC, PVDF, PTFE) and PE wire rope tie rods.
The biggest highlight of the sewage tank cover is the "anti-hanging". The high-strength and corrosion-resistant membrane is on the inside and the exhaust is covered. The steel is supported on the outside and the membrane is suspended. It solves the problem of corrosion durability caused by direct contact of steel support with corrosive gas, and the service life is greatly increased.
In terms of safety, common structural loads are mainly self-weight, wind load, snow load and earthquake action. The self-weight of the membrane is generally only 1kg / ㎡, which is a lightweight and high-strength material. It is most suitable for large-span sewage tanks to minimize the impact of the weight of the material. The shape of the sewage tank is mostly a cone, and due to the need The collected gas is a closed structure as a whole, and the wind will slip through the curved film surface, which will greatly reduce the impact of wind load on the overall structure from the shape; the earthquake effect can be almost ignored, as long as the sewage tank body is stable during the earthquake, The cover will also be secure.
The life of the steel supporting steel is 40-50 years, and the life of the membrane is slightly lower, which can also reach 15-20 years. In general, only the middle of the membrane needs to be replaced, and the cost of the membrane replacement is relatively low. The support does not need to be changed, the main needs to replace the membrane material, reducing maintenance costs, collecting gas needs to be closed, opening the air inlet and air outlet for ventilation.
Membrane structure combined with sewage tank cover treatment is a good combination form, which not only treats the sewage and reduces the environmental pollution, so that we can live a more secure life.
