Description

Technical Field

[0001] The utility model relates to the technical field of environmentally friendly sewage treatment, in particular to a high-efficiency air flotation filter tank. Background Art

[0002] ss suspended solids refers to solid matter suspended in water, including inorganic matter, organic matter, mud, clay, microorganisms, etc. that are insoluble in water. The content of suspended solids in water is one of the indicators to measure the degree of water pollution. ss suspended solids are the main cause of water turbidity. Organic suspended solids in water bodies are prone to anaerobic fermentation after sedimentation, which deteriorates water quality. The current water treatment device has low efficiency and poor effect in removing suspended solids in sewage.

[0003] In the flotation filter, bubbles carry particles in the sewage and float on the surface. A scraper device is needed to scrape these particles to a slag discharge device. However, the scraper devices used in the flotation filters currently on the market are generally driven by a walking trolley to drive a scraper plate to do reciprocating motion to scrape the particles, or a mud scraper is used to scrape the particles. The reciprocating operation can easily break the bubbles and the particles will sink again. Many flotation filters only have one scraper device, which is not flexible enough. When the scraper device is damaged or under maintenance, the flotation filter can only be shut down, delaying production. The scraper plate of the flotation filter using a mud scraper is too long and consumes a lot of energy.

[0004] Therefore, improvements are made to address the above problems. Utility Model Content
