Description

Inclined tube precipitator

Technical Field

The utility model relates to a water quality treatment device, in particular to an inclined tube precipitator.

Background

The conventional inclined tube precipitator comprises a water inlet stirring tank and an inclined tube precipitation tank, wherein a mechanical stirring device is arranged in the water inlet stirring tank, so that sewage can quickly react with a medicament, and the sewage enters the inclined tube precipitation tank for mud-water separation after the sewage reacts in the water inlet stirring tank. At present, the waste water cleaned by a plurality of enterprises often contains a small amount of grease, and because the content of the grease is very low, the cost performance is not high due to the adoption of the air floatation process; and the conventional inclined tube precipitator is adopted for treatment, so that part of flocculating constituents often float on the surface due to oil content, and the effluent exceeds the standard.
