Grid stirring flocculation reaction device

Abstract

The invention discloses a grid stirring flocculation reaction device. The grid stirring flocculation reaction device is composed of a plurality of vertical shafts via series connection; the tops of the vertical shafts are provided with a cover plate; the straight groove of every 1 to 3 rows of the vertical shafts is provided with a stirring machine and a plurality of layers of a grid filling material; each stirring machine is composed of a stirring motor and stirring blades; the stirring motors are arranged on the corridor-type cover plate arranged on the tops of the vertical shafts; the grid filling material is penetrated by stirring shafts; the stirring blades are connected with the stirring motors via the stirring shafts. The grid stirring flocculation reaction device is low in head loss and excellent in effects; effective energy consumption ratio is increased, so that needed flocculation time is shortened, and pond volume is reduced; the grid stirring flocculation reaction device is simple in structure; management, installation, and maintenance are convenient; impact resistance is excellent; water flow conditions are improved greatly; pond bottom sludge deposition is not easily caused; growth of algae on grids, and blocking of grid meshes are not easily caused because of continuous stirring.

Description

technical field [0001] The invention relates to a sewage treatment equipment, in particular to a grid stirring flocculation reaction equipment. Background technique [0002] The flocculation reaction process in the traditional water treatment process is a unit purification process centered on the formation of flocs, and its effect is determined by the chemical action of the flocculant and the physical action of the flocculation reaction facility. There are two types of mechanical flocculation reaction facilities and hydraulic flocculation reaction facilities, and the grid flocculation tank and mechanical flocculation tank are the typical forms of these two reaction facilities. In the grid flocculation tank, raw water and chemicals are mixed and formed by hydraulic flocculation equipment. Large and dense solid flocs visible to the naked eye, the mechanical flocculation tank uses the motor to drive the agitator through the deceleration device to stir the water; but there are m...

[0002] The flocculation reaction process in the traditional water treatment process is a unit purification process centered on the formation of flocs, and its effect is determined by the chemical action of the flocculant and the physical action of the flocculation reaction facility. There are two types of mechanical flocculation reaction facilities and hydraulic flocculation reaction facilities, and the grid flocculation tank and mechanical flocculation tank are the typical forms of these two reaction facilities. In the grid flocculation tank, raw water and chemicals are mixed and formed by hydraulic flocculation equipment. Large and dense solid flocs visible to the naked eye, the mechanical flocculation tank uses the motor to drive the agitator through the deceleration device to stir the water; but there are many shortcomings due to a single mechanical or hydraulic reaction, such as the maintenance workload of a single mechanical flocculation tank Large, high energy consumption, while the single hydraulic stirring type is highly dependent on external environmental factors, and the process is difficult to control
