The invention provides a full glass fiber reinforced plastic deodorizing cover plate with internal integrated air ducts. The full glass fiber reinforced plastic deodorizing cover plate is made of highstrength glass fiber reinforced plastics. The cover plate is formed by connecting a plurality of cover plate units, each cover plate unit comprises two semi-arched flanks on both sides, deodorizing air ducts are formed in the inner sides of the bottoms of the semi-arched flanks, the deodorization air ducts are arranged in the direction of the cross section span of the cover plate, air suction ports are formed in the side faces of the deodorizing air ducts, and air outlet pipes are arranged on the upper portions of both ends of the deodorizing air ducts. According to the full glass fiber reinforced plastic deodorizing cover plate with the internal integrated air ducts, the deodorizing air ducts are integrated in the cover plate, the fact that odor is collected evenly in the space of the lower portion of the cover plate, and dead spaces are avoided; and meanwhile the advantages of convenient disassembly and assembly, safety and beauty are achieved.
