Description

Technical Field

[0001] The utility model relates to a quantitative dosing device, in particular to a quantitative dosing device for sewage treatment. Background Art

[0002] Wastewater treatment refers to the process of physical, chemical and biological treatment of wastewater containing various organic and inorganic substances, suspended solids, microorganisms and other pollutants generated in various fields such as cities, industries, agriculture, and medical care. It aims to remove or reduce pollutants in wastewater and treat it to water quality standards that meet environmental requirements for safe discharge or recycling.
