Quick-acting rotary sand vertical flow circulating water treatment equipment

Abstract

The invention belongs to the field of water treatment equipment, and particularly relates to quick-acting rotary sand vertical flow circulating water treatment equipment. The equipment comprises a water treatment box, the water treatment box is internally provided with a stirring area, a reaction area and a settling area, the stirring area and the reaction area are fixedly connected with a vertical L-shaped partition plate, and two vertical baffles are fixedly connected between the reaction area and the settling area; one baffle is fixedly connected with the inner top wall of the water treatment box, and the other baffle is fixedly connected with the inner bottom wall of the water treatment box; a first motor is fixedly connected to the top wall, corresponding to the stirring area, of thewater treatment box, and a first vertical rotating shaft is fixedly connected to the output end of the first motor. The equipment has the advantages that the equipment can be widely used for mine water treatment occasions, micro-polluted surface water treatment occasions or other various occasions requiring flocculent sedimentation, and is wide in application range, small in occupied area and highin efficiency.

Description

Technical field [0001] The invention belongs to the field of water treatment equipment, and particularly relates to a quick-acting sand whirl vertical flow circulating water treatment equipment. Background technique [0002] The current process used for high and low turbidity wastewater and feedwater treatment uses traditional flocculation sedimentation technology by adding flocculants (mainly polyaluminum chloride or polyferric sulfate) and coagulants (high molecular weight anionic polyacrylamide) The colloid and suspended solids are formed into alum flowers and then settle naturally. This method is currently used more commonly. However, when using traditional techniques, the alum flowers formed after the addition of chemicals are looser, have a lighter specific gravity and a slower sedimentation rate, and require a large enough The floor area (that is, the surface load is small enough) can make most of the flocs settle, so that the effluent meets the design requirements.

AI Technical Summary

Problems solved by technology

[0002] The current process for treating high and low turbidity sewage and water supply adopts traditional flocculation and sedimentation technology, by adding flocculant (mainly polyaluminum chloride or polyferric sulfate) and coagulant (high molecular weight anionic polyacrylamide) The colloid and suspended matter form alum flowers and then settle naturally. This method is currently used more commonly, but when the traditional technology is used, the alum flowers formed after adding the agent are loose, the specific gravity is lighter, and the sedimentation speed is slower, so a large enough alum is required. The occupied area (that is, small enough surface load) can make most of the flocs settle and make the effluent meet the design requirements
