Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a decentralized wastewater treatment device. Background Technology

[0002] Decentralized wastewater treatment systems are environmentally friendly devices specifically designed to treat decentralized domestic sewage, effectively addressing the problem of low sewage collection and treatment efficiency. These systems are typically used in areas where large-scale sewage treatment plants are difficult to construct or where centralized sewage treatment facilities are difficult to cover, such as rural areas, towns, and remote regions. In general, decentralized wastewater treatment systems are efficient, environmentally friendly, intelligent, and flexible wastewater treatment equipment, effectively solving the problem of decentralized domestic sewage treatment and providing strong support for environmental and water resource protection. However, existing decentralized wastewater treatment systems still have some drawbacks. For example, the sewage cannot be filtered with sand and gravel before entering the system, resulting in a large amount of sand and gravel entering the device. Over time, this affects the filtration effect and damages the internal structure of the system. Furthermore, some impurities settled at the bottom of the system are difficult to clean, further impacting the treatment effect. Therefore, we propose a decentralized wastewater treatment system.

The collection box can be removed from the bottom of the filter elements; operators only need to periodically disassemble the collection box to remove the filtered sand and gravel, greatly increasing the filtration efficiency. When wastewater enters the sedimentation chamber, impurities settle at the top of the lifting plate. At this time, the servo motor drives the external threaded rod to rotate via the motor shaft. The rotation of the external threaded rod causes the threaded lifting plate to move up and down, and the impurities accumulated at the top of the lifting plate are moved to the top of the sedimentation chamber. Operators can then remove the cover plate via the servo motor for cleaning. Attached Figure Description
