Abstract

The invention discloses an environment-friendly variable range flocculation unit for sewage treatment. The environment-friendly variable range flocculation unit comprises a flocculation tank, wherein a first stirring shaft is arranged in the flocculation tank; helical mixing blades are arranged on the outer part of the first stirring shaft; a driven gear is arranged on a part, which is positioned below the flocculation tank, of the first stirring shaft; one side of the driven gear is meshed with a driving gear; the driving gear is driven by a first motor; a first cavity is formed in the lower half part of the first stirring shaft; the lower end of the first stirring shaft is communicated with an air inlet pipe through a rotary air pipe joint; a plurality of first through holes communicated with the interior of the flocculation tank are formed in the first cavity; a second cavity is formed in the upper half part of the first stirring shaft; and a plurality of second through holes communicated with the flocculation tank are formed in the second cavity. The environment-friendly variable range flocculation unit disclosed by the invention has the beneficial effects that the sewage and flocculating agent are effectively mixed by utilizing a horizon bar, effective flocculation can be realized by utilizing the helical mixing blades and gas-flow mixing, and the sewage treatment effect is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an environment-friendly variable range flocculation device for sewage treatment. Background technique [0002] Flocculation refers to the process in which fine aggregates or coarse particles in solution formed by coagulation form coarse flocs in the presence of bridging substances and turbulent water flow. It is a process mainly based on physical aggregation. The coagulation process involves a complex balance of a series of variable factors, including: the physical and chemical properties of colloidal impurities in the solution, the coexistence of salts in water, the properties of the solution itself (such as pH value, temperature, etc.), the performance of the mixing agent and external forces effect (such as stirring conditions, etc.). [0003] Existing flocculation often requires a stirring device, but the stirring effect of the existing stirring device is poor, and i...
