Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a sedimentation separation device for sewage treatment. Background Art

[0002] Wastewater refers to wastewater, sewage and waste liquid generated in the process of industrial production, which contains industrial production materials, intermediate products and products lost with water, as well as pollutants generated in the production process. With the rapid development of industry, the types and quantities of wastewater have increased rapidly, and the pollution of water bodies has become increasingly widespread and serious, threatening human health and safety. Wastewater refers to wastewater, sewage and waste liquid generated in the process of industrial production, which contains industrial production materials, intermediate products and products lost with water, as well as pollutants generated in the production process.

[0003] After searching, the invention patent with Chinese patent number CN118771651 B discloses a sedimentation separation device for sewage treatment. Compared with the prior art, the invention patent with Chinese patent number CN118771651 B continuously rotates the stirring plate, and the air holes are evenly arranged at the bottom of the stirring plate. When air continuously enters the sewage through the air holes, the continuous rotation of the stirring plate drives the air outlet position in the sewage to continuously change, so that the range of bubbles in the sewage is wider, and the aeration range is further expanded, thereby increasing the contact probability of impurities in the sewage and increasing the sedimentation rate.

[0004] However, in actual use of the above-mentioned device, for sewage containing a large amount of colloidal particles, soluble organic matter or tiny suspended matter, simple physical stirring may be difficult to achieve the expected effect. The pollutants in this type of sewage are often relatively stable and are not easy to form larger flocs and quickly precipitate through simple physical stirring. In addition, during the use of the above-mentioned device, the sediment is accumulated on the inside of the device. Too much sediment will clog the bottom of the device, thereby affecting the normal use of the device. Therefore, it is necessary to propose a sedimentation and separation device for sewage treatment.
