Description

Technical Field

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

[0002] Wastewater treatment is the process of removing harmful substances from sewage through physical, chemical, biological and other methods to make it meet discharge standards or water quality requirements for reuse. During the sewage treatment process, it is often necessary to add flocculant particles in a timely manner to accelerate the precipitation of impurities in the water.

[0003] At present, in order to automatically add flocculant particles, workers will use automatic dosing equipment to add them. Therefore, the flocculant particles need to be placed in the automatic dosing equipment for storage. During long-term storage, the flocculant particles are very likely to clump due to moisture, and thus cannot be added smoothly. To this end, we propose a dosing equipment for sewage treatment to solve the above-mentioned problems. Utility Model Content
