Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a feeding and mixing device for wastewater treatment. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of the daily lives of ordinary people.

[0003] Existing wastewater treatment feeding and mixing devices still have some shortcomings. Most wastewater treatment feeding and mixing devices require the addition of chemical reagents during use. The depth to which the chemical reagents enter the wastewater is fixed, and multiple depths cannot be added. In addition, the mixing speed of a single stirring rod is limited. Therefore, we propose a wastewater treatment feeding and mixing device. Utility Model Content
