Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more specifically, to a device for harmless treatment of potato starch wastewater. Background Art

[0002] Potato is an important food crop and industrial raw material, and is widely grown around the world. The production process of potato starch involves soaking, washing, and separation of raw materials. These processes will produce a large amount of organic matter, such as starch, protein, sugar, fat, etc. Potato starch wastewater is a high-concentration organic wastewater containing a large amount of suspended solids, organic matter, nitrogen, phosphorus and other pollutants. If it is discharged directly without treatment, it will cause serious pollution to the environment.

[0003] Most of the traditional wastewater harmless treatment devices filter through filter plates, but this structure will cause impurities in the wastewater to remain on the upper end of the filter plate. Long-term use will cause the filter plate to be blocked. If it is not cleaned in time, it will affect the treatment effect.

[0004] In the process of treatment, flocculants are generally added to precipitate impurities in the wastewater. However, most traditional treatment devices directly add flocculants into the sedimentation tank and do not have a stirring mechanism, resulting in a slow mixing rate of the flocculant in the later stage, affecting the wastewater treatment efficiency.
