Flocculation equipment for sewage treatment based on chain drive lifting principle
Technical Field
The invention relates to the technical field of sewage, in particular to flocculation equipment for sewage treatment based on a chain transmission lifting principle.
Background
Sewage, generally refers to effluent water from life and production that is contaminated to some extent. The sewage mainly comprises domestic sewage, industrial wastewater and initial rainwater. The main pollutants of the sewage include pathogen pollutants, oxygen-consuming pollutants, plant nutrients, toxic pollutants and the like. Sewage treatment (sewerage treatment, wateraster treatment): the sewage is purified to reach the water quality requirement of draining a certain water body or reusing the water body. Sewage treatment is widely applied to various fields such as buildings, agriculture, traffic, energy, petrifaction, environmental protection, urban landscape, medical treatment, catering and the like, and is increasingly used in daily life of common people.
In the treatment of sewage, one of the most used is flocculation technology. Flocculation refers to the process of making suspended particles in water or liquid agglomerate or form flocs, thereby accelerating the coagulation of particles and achieving the purpose of solid-liquid separation, and this phenomenon or operation is called flocculation. Flocculation is generally carried out by adding a suitable flocculating agent, the effect of which is to adsorb the particles, to "bridge" the particles, and thus to promote agglomeration. In the latex industry, flocculation is the first stage of latex coagulation, an irreversible aggregation. The flocculating agent is typically an ammonium salt type electrolyte or an adsorptive colloidal chemical.
Before carrying out flocculation to sewage, in order to make the flocculation effect obtain the best, need to make flocculating agent and sewage can obtain abundant effectual mixed treatment usually, prior art utilizes stirring vane to stir the processing to sewage, but because flocculation cell volume is great, and the disturbance scope is less, can't realize the effective mixing of flocculating agent and sewage.
