Description

Technical Field

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

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Direct discharge of untreated wastewater can severely pollute natural water bodies such as rivers, lakes, and oceans, disrupting the balance of aquatic ecosystems. Harmful substances in wastewater can cause the death of aquatic organisms, deteriorate water quality, and affect aquatic biodiversity and ecological functions. For example, excessive nitrogen and phosphorus in water bodies can lead to algal blooms, red tides, or algal blooms, depleting oxygen and causing fish and other aquatic animals to suffocate and die. Wastewater treatment removes pollutants, allowing wastewater to meet certain water quality standards for reuse. It can be transported to points of use through dedicated reuse networks. During reuse, water quality monitoring and management are necessary to ensure the safety and stability of the reused water and prevent adverse effects on human health and the environment due to improper reuse.

[0003] Patent publication number "CN221889349U" discloses "a sewage treatment device", which includes a sewage treatment tank and an auxiliary cleaning component. The upper part of the sewage treatment tank is provided with a movable cleaning component, which includes a side plate fixedly connected to the side wall of the sewage treatment tank, a first housing, and a second housing. A rotating scraper is rotatably connected between the second housing and the first housing. A movable anti-splash shell is provided on the upper part of the rotating scraper. In this sewage treatment device, the motor drives the threaded rod to rotate, the rotation of the threaded rod drives the moving block to move, the movement of the moving block drives the rotating scraper to rotate, the rotation of the rotating scraper drives the gear to rotate, and the rotation of the gear drives the rotating scraper to clean the garbage on the outer surface of the filter screen while rotating and moving. The movable anti-splash shell prevents splashing when the rotating scraper cleans the garbage.

[0004] The device in the aforementioned patent uses a threaded rod to rotate, which drives a moving block to move. The moving block then drives a rotating scraper to rotate, which in turn drives a gear to rotate. The gear then drives the rotating scraper to move while rotating, cleaning the debris on the outer surface of the filter screen. However, if the debris has a strong adsorption capacity, the rotating scraper may not achieve the desired cleaning effect. On the one hand, the scraper may not be able to effectively remove the highly adsorbed debris. On the other hand, if the gaps between the scrapers are too large, some debris may remain and be difficult to clean thoroughly. Utility Model Content
