Embodiment Construction

[0042] The present invention will be further described in detail below in conjunction with the drawings.

[0043] Such as figure 1 with Figure 8 As shown, a micro-vortex coagulation sedimentation clarification tank with power and water saving without mechanical stirring, increment and quality upgrading, includes an inlet pipe 1, an outlet pipe 20, and a flocculation device and a clarification device arranged in the clarification tank. The flocculation device is set In the center of the sedimentation tank, the clarification device is set in the annulus between the flocculation device and the side wall of the sedimentation tank; the inlet pipe 1 is connected to the vortex mixing equipment 2, and the entrance of the vortex mixing equipment 2 is provided with a flocculant dosing port 27 and the outlet is opened Coagulant dosing port 28; among them,

[0044] The flocculation device includes a multi-stage folded plate flocculation channel 5 and a multi-stage grid flocculation channel 6....

Abstract

The invention discloses an electricity-saving water-saving non-mechanical stirring incremental upgrading microvortex coagulating sedimentation clarification pond and belongs to water treatment equipment. The problems that the conventional mechanical stirring clarification pond is high output water turbidity and unsmooth in turnover and mud discharge, machines are liable to damage and the water making force cannot meet the requirement are mainly solved. The electricity-saving water-saving non-mechanical stirring incremental upgrading microvortex coagulating sedimentation clarification pond comprises a water inlet pipe, a water outlet pipe, a flocculation device and a clarification device, wherein the water inlet pipe and the water outlet pipe are communicated with eddy mixing equipment; theflocculation device is arranged in the center of the clarification device; the clarification device is arranged in an annular space between the side walls of the flocculation device and the clarification device; and mechanical stirring is replaced by disturbance and flocculation of multi-stage folded plate flocculation channels and multi-stage grid flocculation channels, so that water is completely purified under the action of gravity flow, the turbidity is reduced, electricity and energy are saved, discharge of sewage is reduced and the treatment quantity of sludge is reduced.

Description

Technical field [0001] The invention relates to the field of raw water pretreatment and sewage treatment, and in particular to a micro-vortex coagulation sedimentation clarifier for power-saving and water-saving without mechanical agitation and incremental quality upgrading. Background technique [0002] In recent years, the coagulation sedimentation treatment process of raw water, sewage, and wastewater includes three stages: mixing of water and chemicals, reactive flocculation and water clarification and separation. The clarification tank is a kind of equipment that completes the above process. Among them, the mechanical stirring clarification tank is a common clarification tank. Its working principle is to use machinery to lift and stir the water, promote the circulation of sludge, and make the solid impurities in the water contact with the formed sludge to flocculate and separate and settle. The high-density clarification tank is a variant of the mechanical agitation clarific...
