Anti-aging thermal-insulation sealing tent cover for float type sewage pool

Abstract

The invention relates to an anti-aging thermal-insulation sealing tent cover for a float type sewage pool, which comprises a tent body of a multilayer structure. The tent body at least comprises a sunshine anti-aging layer, a thermal-insulation layer and an anticorrosion layer which are sequentially arranged from top to bottom, wherein the sunshine anti-aging layer is made of building membrane materials, the thermal-insulation layer is made of foam thermal-insulation materials, and the anticorrosion layer is made of plastic plates. The anti-aging thermal-insulation sealing tent cover is free of steel structures, reinforced concrete and complex processes, low in cost, convenient in construction and especially suitable for sealing of used sewage pools and methane recovery of anaerobic sewage pools. The anti-aging thermal-insulation sealing tent cover can effectively resolve the problems of thermal-insulation sealing of sewage pools, foul gas environmental pollution reduction, sewage treatment methane recovery, sewage plant environment beautification, and the like.

Description

technical field [0001] The invention relates to a tarpaulin, in particular to an anti-aging tarpaulin used for heat preservation and sealing of a sewage pool. Background technique [0002] In the process of sewage treatment, especially industrial sewage treatment and anaerobic process pools for sewage treatment, due to the large span of sewage pools, open-air sewage pools are often used, which will produce foul-smelling gases that pollute the surrounding environment and directly affect people's lives and health. At the same time, it is necessary to keep the temperature constant during the biochemical treatment of sewage. The open-air pool emits a lot of heat. In winter, auxiliary heat sources are often used for heating, which wastes a lot of energy. On the other hand, a large amount of biogas generated in the anaerobic process will also Distributed into the air, polluting the air, causing potential fire hazards, waste of energy from biogas, and so on. For this reason, the t...

Problems solved by technology

[0003] The traditional method is to use reinforced concrete structure for sealing. The amount of reinforced concrete is large and the cost is high. At the same time, since a lot of pipeline equipment such as water replenishment and return flow and biogas recovery are added to the sewage treatment tank, maintenance is very inconvenient, especially for those who have solved the problem. The construction of the built sewage pool is very difficult to seal; the second is that in recent years, the landscape membrane structure technology has been applied to the sealing of the sewage pool. Disadvantages such as leakage, especially the steel structure is easy to corrode, and maintenance is difficult and risky
