Description

Technical Field

[0001] The utility model belongs to the technical field of sewage precipitation, and in particular relates to a precipitation device for chemical sewage. Background Art

[0002] Chemical wastewater refers to wastewater produced in the process of producing products in chemical plants, such as oily wastewater from the production of ethylene, polyethylene, rubber, polyester, methanol, ethylene glycol, oil tank areas, and air separation and air compression stations. After biochemical treatment, it can generally meet the national secondary emission standards. Due to the shortage of water resources, the water that meets the emission standards needs to be further deeply treated so that it can be recycled and reused to meet the requirements of industrial water replenishment.

[0003] When the sedimentation devices for chemical wastewater on the market are in use, the residues in the wastewater can easily cause blockage on the filter screen, and most of them need to be cleaned manually, resulting in low work efficiency. Drugs are mostly added during the sedimentation process to precipitate impurities, but the reaction between drugs and wastewater is relatively slow, resulting in a long sedimentation time. When the precipitated water is discharged, some tiny impurities will be discharged together, which affects the sedimentation treatment effect of the wastewater and reduces its purity. Utility Model Content

The cleaned debris is concentrated in the cleaning frame 3 for centralized treatment, which plays a role in preventing the filter screen 5 from being blocked by debris. Through the setting of the stirring mechanism 6, the second motor 601 drives the rotating shaft 602 to rotate, and then drives the blade 604 to stir, so that the suspended matter in the sewage is fully in contact with the flocculant, which plays a role in improving the sedimentation effect. The efficiency of the sedimentation treatment is relatively high. Through the setting of the filtering mechanism 7, the rotating handle 707 is turned to drive the rotating plate 705 to rotate, and the precipitated water enters the outlet pipe 701, and is filtered again by the first filter plate 702 and the second filter plate 704. The activated carbon filter plate 703 absorbs impurities in the water, which plays a role in preventing the precipitated water from being discharged with some tiny impurities.
