Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and specifically relates to a sewage treatment dosing device. Background Art

[0002] The worsening water pollution situation has brought unprecedented attention to the wastewater treatment and recycling industries. Based on the source of the wastewater, wastewater treatment is generally divided into industrial wastewater treatment and domestic wastewater treatment. Industrial wastewater includes industrial wastewater, agricultural wastewater, and medical wastewater, while domestic wastewater is the wastewater generated by daily life and is a complex mixture of various inorganic and organic substances. Several chemicals are used in the sewage treatment process. There are many types of sewage treatment chemicals, the most commonly used of which are flocculants. Flocculants can be divided into inorganic flocculants and organic flocculants. Inorganic flocculants are divided into low-molecular-weight and high-molecular-weight inorganic flocculants based on molecular weight. Organic flocculants are divided into ionic and non-ionic types. Ionic organic flocculants can change the surface charge of particles and act as a bridge to cause flocculation. During use, the selected chemical must first be mixed with a certain proportion of water until it mixes with the sewage. Existing dosing devices cannot ensure that both mixing steps are fully agitated, thus preventing the chemical from being fully utilized and reducing the effectiveness of the sewage treatment.
