FRP (Fiberglass Reinforced Plastics) floating cover

Abstract

The invention discloses an FRP (Fiberglass Reinforced Plastics) floating cover and belongs to the technical field of sewage treatment. The FRP floating cover comprises a plate body, wherein connecting seats are symmetrically arranged at the left and right sides of the top of the plate body, a polyurethane foamed layer is arranged in the internal chamber of the plate body, reinforcing ribs are arranged at the top of the polyurethane foamed layer, buoyancy partition plates are uniformly arranged at the bottom of the polyurethane foamed layer, and a hollow chamber is formed between every two adjacent groups of buoyancy partition plates. According to the FRP floating cover, an FRP structure is adopted, and the polyurethane foamed layer is arranged in the middle of a cover plate, so that the cover plate can float on the water and can resist snow damage; the cover plate directly covers a water surface, so that the volume of volatilized exhaust gases of wastewater is reduced, and the gathering and treatment of the exhaust gases are facilitated; the FRP floating cover is relatively light in weight, so that the overall structure of a sewage tank is not affected, and the weight load is not increased fundamentally; the cover plate only has thickness volume, does not take up space fundamentally and is not affected by the width of the sewage tank, so that the difficulty in covering of wide-span sewage tanks is overcome; the cover plate is formed in a modular assembled manner, so that the mounting is simple, and the mounting cost is relatively low.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an FRP floating cover. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. At present, the discharge of urban domestic sewage is the main pollution source of urban water in China, and the treatment of urban domestic sewage is the top priority of urban water conservation and urban water environment protection at present and in the future. This requires us to take the construction of domestic sewage treatment facilities as a priority The important content of urban infrastructure is to be g...
