Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and in particular relates to an automatic dosing device for a sewage treatment plant. Background Art

[0002] At present, the treatment devices on the market add the prepared water treatment chemicals directly into the sewage pool, and then stir the sewage to make the impurities react with the treatment chemicals. It is not possible to spray the chemicals quantitatively to treat the sewage. Moreover, the sewage is stirred manually, which is troublesome to operate and the treatment effect is not ideal. Moreover, it is complicated to disassemble the device when it needs maintenance. During use, since most of the dosing nozzles are fixedly installed inside the device, the spraying direction is fixed when spraying the drugs, causing the drugs to aggregate and unable to disperse evenly, making it impossible for the drugs to quickly and evenly blend with the sewage, thereby affecting the reaction rate of the drugs and sewage and reducing the flocculation effect. For this reason, we propose an automatic dosing device for sewage treatment plants. Utility Model Content
