Background
At present, odor treatment of a sewage treatment plant is a content of major concern in the design and operation process of the sewage treatment plant. For deodorization, the upper part of the structure should be sealed, and the common sealing means include a glass fiber reinforced plastic awning, a glass fiber reinforced plastic arc cover plate, etc. However, some structures are difficult to be effectively sealed by covering, such as an aeration grit chamber and a rectangular primary settling chamber, and the upper part of the structure is generally provided with a movable suction dredge. If the sealing form of the awning is adopted, the suction dredge needs to be completely sealed in the awning. The method not only increases the required deodorization volume and increases the engineering cost, but also enables the mechanical equipment to be always in a closed space with extremely high water vapor concentration, causes the corrosion of the mechanical equipment and shortens the service life of the equipment.
If the glass fiber reinforced plastic arc cover plate is used for covering, a wider seam is required to be formed in the middle of the arc cover plate for the sand sucker to move back and forth. Thus, the odor is leaked, and the sealing effect is poor.
