DEVICE FOR REMOVING FLOATING AND WEIGHTED WASTE FROM THE PLANTS OF BIOLOGICAL CLEANING OF SEWERAGE WASTE (OPTIONS)

摘要

The utility model relates to structural elements of sewage treatment plants, in particular, plants designed for biological treatment of domestic sewage (UBO) of detached houses and cottages. The technical problem solved by this utility model is to increase the efficiency of biological treatment plants for domestic wastewater by ensuring the removal of large contaminants from them. The solution to this problem is provided by the fact that the device for removing floating and suspended debris from the UBO is equipped with a stand with quick-detachable means for installing it in a vertical working position and different transverse teeth made with hook-shaped bent ends, while the said teeth are made with a regular increase in the transverse span teeth from the upper to lower teeth along the rack in the direction from its upper part to the opposite end part. In embodiments, the working surface of the rack can be either multifaceted or cylindrical; one of the faces of the multifaceted working surface of the rack is made without teeth; the working surface of the rack is cylindrical, while the teeth are located on the entire working surface of the rack; the working surface of the rack is made cylindrical, while the teeth are located only on one of the semi-cylindrical parts of the working surface; the working surface of the rack is made semi-cylindrical, while the teeth are located only on the cylindrical part of the working surface. The stand, teeth and quick-release tool are made of a polymeric material, for example, polyethylene and / or vinyl plastic, or other similar materials. Quick-detachable means for installing the rack is made in the form of a hook-latch mounted on the end of the rack, or in the form of a locking annular thickening made on the upper end of the rack, while the device can be made disposable. In another embodiment, the transverse teeth are made in the form of arcuate curved rods installed along the height of the uprights, while the teeth adjacent to the height have the opposite direction of bending. In an embodiment, the upper part of the rack is additionally equipped with a stopper in the form of an annular thickening made with the possibility of locking relative to the latch fixed in the UBO case when the rack is installed in the vertical operating position. The technical effect of using the proposed utility model is the ability to remove floating and suspended garbage from biological treatment plants and thereby increase the efficiency and quality of sewage treatment.
