Characteristics of Membrane Structures for Sewage Treatment Ponds
1. Lightweight
The low self-weight of tensile structures stems from their reliance on pre-stressing rather than material properties to maintain structural stability. This results in significantly reduced self-weight compared to traditional building structures while retaining excellent stability. Architects can leverage their lightweight, large-span characteristics to design structural details, organically integrating lightness with structural integrity.
2. Light Transmission
Light transmission stands as one of the most widely recognized characteristics of modern membrane structures. The translucency of membrane materials provides buildings with necessary illumination, which is crucial for energy efficiency. This is particularly vital for commercial buildings requiring abundant light and high brightness. By integrating natural and artificial lighting, the light transmission properties of membrane materials offer greater aesthetic design possibilities for architectural planning. At night, translucency transforms membrane structures into luminous sculptures. The translucency of membrane materials is determined by their underlying fibers, coatings, and colors. Standard membrane materials typically have a spectral transmittance ratio between 10% and 20%, while some can reach up to 40%. Conversely, certain membrane materials are completely opaque. The translucency and color selection of membrane materials can be adjusted through coating colors or surface finishes. By appropriately combining membranes with translucent insulating materials, multi-layered membranes incorporating insulation can achieve translucency. Even with spectral transmittance of just a few percentage points, membrane roofs appear luminous and translucent to the human eye, maintaining the visual appeal of lightweight roofing.
Advantages of Membrane Structure Sewage Tanks
1. Long service life: Membrane material lasts 15-20 years, while steel structures endure up to 50 years;
2. Simple fabrication: Both membrane and steel components are prefabricated in factories, ensuring reliable quality control;
3. Suitable for large-span structures: Membranes are lightweight with high tensile strength. Special UV-cured treatment provides superior corrosion, mold, and bacteria resistance. Ideal for large spans, offering diverse, aesthetically pleasing designs;
4. Rapid Installation: Prefabricated membrane materials and steel structures are transported to the construction site for straightforward assembly, minimizing site occupation;
5. Easy Maintenance: Due to process requirements, regular equipment inspections and maintenance are necessary. This can be facilitated by incorporating pre-installed access doors and walkways in the perimeter membrane. In wastewater treatment, covers are required to seal tanks during construction or process needs. This prevents wastewater vapor from polluting the surrounding environment while allowing personnel and machinery to access the surface for construction work. Consequently, cover plates for sewage treatment tanks must meet stringent requirements across all aspects.
